The `privileged_users` list is an un-named + capability bundle with no normative basis in the FIPS module boundary, creating + ambiguity in compliance audits. + +2. **Permission granularity.** `privileged_users` conflated two distinct concerns in a + single undifferentiated list: key-lifecycle capability (Create, Import) and + access-delegation capability (granting the Create right to others). It provided no + way to separate crypto-use operations (Encrypt, Decrypt, Sign…) from key-management + operations, and conferred no ownership-bypass for cross-object administration. + +3. **No split-key ceremony path.** There was no mechanism to enforce dual control / + split knowledge (NIST SP 800-57 Part 2 Rev 1 §4.6) for key-lifecycle operations. + Any user listed in `privileged_users` gained full capability immediately, with no + option for a m-of-n quorum activation ceremony at the module boundary. + +## Decision + +Replace `privileged_users` with two formal FIPS-aligned roles.

This implements NIST SP 800-57 Part 2 +Rev 1 §4.6 (dual control / split knowledge) directly within the module boundary without +requiring external tooling. + +Ceremony activation records are AES-256-GCM encrypted with keys derived from +`KMS_CEREMONY_SECRET`, preventing forgery via direct database writes. + +### Audit and advanced RBAC + +For deployments requiring finer-grained audit roles (`Auditor`, `DomainAdmin`, +`SuperAdmin`, `User`) or cross-domain isolation, the OPA integration path +(`--opa-server-url`) is the recommended mechanism.

The former `privileged_users` flat list is + replaced by `crypto_officer_users` with explicit, documented permission semantics. +- **POS-003**: `RolesConfig` is trivially correct — a single `CryptoOfficerConfig` + with no cross-role consistency checks to maintain. +- **POS-004**: Test vectors now cover both role paths explicitly (`crypto_officer_role_*` + and `operator_role_*`) giving clear behavioral contracts for each role. +- **POS-005**: Ceremony activation is a first-class CryptoOfficer feature built + directly into `CryptoOfficerConfig` — operators see one cohesive ceremony flow. + +### Negative + +- **NEG-001**: Deployments using `privileged_users` must migrate: the config key must + be renamed to `crypto_officer_users` (under the new `[roles]` section) and the + `--privileged-users` CLI flag replaced with `--crypto-officer-users`. Servers with + old configs will emit a parse error on startup. +- **NEG-002**: There is no built-in Auditor role. Deployments requiring compliance + reporting or read-only audit access must use the OPA integration path + (`--opa-server-url`) with the reference policy in `test_data/opa/kms.rego`. +- **NEG-003**: The OPA path requires an external sidecar; teams without OPA must rely + on database-level or application-level audit logs for auditor-style access control. + +## Alternatives Considered + +### Keep privileged_users unchanged + +- **ALT-001 Description**: Retain `privileged_users` as the sole access-control + mechanism, possibly adding documentation mapping it to the Crypto Officer concept. +- **ALT-002 Rejection Reason**: The flag name carries no normative meaning, making + compliance audit evidence weaker.

Improves on the current model where the reconstructed key becomes a managed object. | +| **ADP-25** | Server generates the 256-bit ceremony secret internally (random); the operator-supplied `ceremony_secret` TOML field is removed. | +| **ADP-3/15** | CO candidates assigned per-domain;

A dealer generates $n-1$ uniformly random byte strings, each of the same length $\ell$ as the secret $s$. +2. The final share is the XOR of the secret with all other shares: $r_n = s \oplus r_1 \oplus \cdots \oplus r_{n-1}$. +3.

Crypto Officer Role

+

+ This role can operate in config-only mode (immediately active) or ceremony mode (dormant until a + split-key ceremony completes). See{" "} + + Key ceremony documentation + {" "} + for details. +

+/**
+ * Crypto Officer Role — "Create & Split Key (3 shares)" E2E tests.
+ *
+ * Covers the integrated split-key workflow on the `/ui/access-rights/crypto-officer` page
+ * when the server is running with ceremony mode configured
+ * (test_data/configs/server/rbac/crypto_officers.toml — 3 CO candidates).
+ *
+ * ## Prerequisites
+ *
+ * These tests require a ceremony-configured KMS server and must be run with:
+ *
+ * ```bash
+ * # Build UI and start server
+ * pnpm -C ui build
+ * cargo run -p cosmian_kms_server --features non-fips -- \
+ *   -c test_data/configs/server/rbac/crypto_officers.toml
+ *
+ * # Run tests
+ * cd ui
+ * PLAYWRIGHT_BASE_URL=https://127.0.0.1:9998 \
+ * PLAYWRIGHT_CEREMONY_SERVER=true \
+ *   pnpm run test:e2e tests/e2e/co-role-split-key.spec.ts
+ * ```
+ *
+ * The `clientCertificates` in `playwright.config.ts` automatically present
+ * `owner.client.acme.com.crt` (owner.client@acme.com, a CO candidate) for the
+ * `https://127.0.0.1:9998` origin — this is the user authenticated by the tests.
+ *
+ * ## Why "Failed to fetch" in a regular browser
+ *
+ * The ceremony server config enables TLS + mTLS client certificate authentication.
+ * A regular browser without the client certificate installed fails at the TLS
+ * handshake — this is the expected security behaviour, not a bug.
+ * Playwright resolves this via its `clientCertificates` configuration.

Subject: [PATCH 006/181] feat(co-ceremony): add create-split-key subcommand to
 crypto-officer CLI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add `ckms access-rights crypto-officer create-split-key` command
  * Creates a fresh AES-256 key (optional --key-id for custom UID)
  * Stamps x-cosmian-crypto-officer-ceremony vendor attribute
  * Calls CreateSplitKey — server auto-assigns n=custodians_count shares
  * Each share owned by a different CO candidate (round-robin)
  * Validates ≥2 CO candidates configured before proceeding

- fix(split-key): ceremony mode activates when require_ceremony=true AND
  CO users are configured (global server enforcement), not only via key attribute

- fix(split-key): use owm.id() for share UID naming when caller passes a tag

- fix(clippy): Box::pin around ONCE.get_or_try_init in test_server.rs

- fix(co-ceremony): crypto_officer_disable() sends valid JSON body

- fix(lychee): exclude webstore.ansi.org (returns 403 to automated crawlers)

   to clarify all shares are required.
 - **JoinSplitKey dialog**: method selector removed (XOR is the only option). Description updated
   to clarify all shares are required for n-of-n reconstruction.
+- **Dark theme aligned with the documentation site**: the Web UI dark theme now reuses the same
+  mdBook "navy" palette as `docs.cosmian.com` (near-black `#161923` background, `#bcbdd0` text,
+  `#282d3f` sidebar) instead of the previous gray surfaces. The light theme uses the darker brand
+  orange `#c73f1b` for the primary accent. The sidebar menu and all surfaces now switch together
+  with the light/dark toggle.
+- **Contrast fixes (WCAG AA)**: resolved unreadable colour combinations in dark mode — dark text on
+  the black background (`text-gray-800`, `text-blue-800`, `text-red-800`), light-gray helper text on
+  white, near-invisible borders, and the low-contrast orange/teal accents — now meet AA contrast in

+name: 'Web UI i18n / Localization'
+description: 'Keep en and zh-CN locale bundles in sync and follow the useTranslation/Trans conventions'
+applyTo: 'ui/src/i18n/**/*.{ts,json}'
+---
+
+# Web UI i18n / localization
+
+The UI is localized with `i18next` + `react-i18next`. Every user-facing string must be a
+translation key — never hardcoded English in components. The two shipped locales are `en`
+(English) and `zh-CN` (Simplified Chinese).
+
+## Architecture
+
+- `ui/src/i18n/index.ts` — `i18next` init; `fallbackLng: "en"`; detection order `localStorage` → `navigator`.
+- `ui/src/i18n/localeRegistry.ts` — `LOCALE_REGISTRY` maps each locale to its resource bundles;
+  `SUPPORTED_LOCALES` is derived from it.
+- `ui/src/i18n/useAppLocale.ts` — hook returning the AntD/dayjs locale and keeping `` in sync.
+- Namespaces: `common`, `menu`, `layout`, `locate`, `actions` — one JSON file each, per locale, under `locales//`.
+
+## Checklist
+
+- [ ] **en/zh-CN parity is mandatory.** Every key added to `locales/en/*.json` must also be added to
+      the matching `locales/zh-CN/*.json` with a real Chinese translation — never copy the English text,
+      never skip it. Because `fallbackLng` is `en`, a missing `zh-CN` key silently renders English, so
+      parity must be verified explicitly (see below).
+- [ ] **Key naming** — `camelCase`; one top-level key per feature in `actions.json`
+      (e.g. `splitKey`, `joinSplitKey`, `cryptoOfficer`, `hsmStatus`). Common suffixes: `title`, `intro`,
+      `submit`, `responseTitle`, `success`, `error*`, `noInstances`.
+- [ ] **Interpolation** uses `{{var}}` in the value, passed via `t("ns.key", { var })` or
+      ``.
+- [ ] **HTML inside a translation must use ``, never `t()`**:
+      `, em: , a: , code:  }} />`.
+      The tag names in the translation string must match the `components` keys.
+- [ ] **Menu labels** live in `menu.json`; the key is the route path (e.g. `access-rights/crypto-officer`,
+      `sym/keys/split`). Every entry in `ui/src/menuItems.tsx` must have a key in both `en` and `zh-CN`.
+- [ ] **In components**: `const { t } = useTranslation("actions");` and
+      `import { Trans, useTranslation } from "react-i18next";`. Do not hardcode English strings.
+- [ ] **Adding a locale** (e.g. `fr`): create `locales/fr/*.json`, import them in `localeRegistry.ts`, and
+      add a `LOCALE_REGISTRY` entry with `label`, `antdLocale`, `dayjsLocale`, `matches`, and `resources`.
+
+## Verification
+
+```bash
+cd ui
+# JSON validity
+python3 -c "import json; json.load(open('src/i18n/locales/en/actions.json'))"
+# en/zh-CN key parity (run for each namespace)
+python3 -c "import json; a=json.load(open('src/i18n/locales/en/actions.json')); b=json.load(open('src/i18n/locales/zh-CN/actions.json')); print(set(a)-set(b), set(b)-set(a))"
+pnpm exec tsc --noEmit
+```
+
+> React/AntD/Tailwind conventions: `typescript-ui.instructions.md`. CLI ⇔ UI feature parity: `cli-ui-sync.instructions.md`.

Subject: [PATCH 008/181] fix(e2e): retry on transient 'Failed to fetch' in key
 creation helpers

submitWithFetchRetry() re-navigates and re-applies form setup on a
transient network error before surfacing a hard assertion failure.
createRsaKeyPair/createEcKeyPair/createPqcKeyPair all use it.

Also set retries:1 for both local and CI runs (was CI-only) so a
single transient flake does not fail a local run.

 - `AlwaysSensitive` is now server-managed: clients can no longer add/set/modify/delete it via `AddAttribute`, `SetAttribute`, `ModifyAttribute`, or `DeleteAttribute` — such requests are rejected with `Attribute_Read_Only` ([#1103](https://github.com/Cosmian/kms/pull/1103))
 - Read-only KMIP attributes could be rewritten by any client via `ModifyAttribute` (e.g. `Initial Date`, `Cryptographic Length`, `Unique Identifier`). All attributes marked "Modifiable by client: No" are now rejected with `Attribute_Read_Only`; "Deletable by client: No" attributes are rejected by `DeleteAttribute` ([#1103](https://github.com/Cosmian/kms/pull/1103))

From 2bf34d7d82e446b27e0a0a7d6d54137352f9f350 Mon Sep 17 00:00:00 2001
From: Manuthor 
Date: Mon, 17 Aug 2026 15:38:38 +0200
Subject: [PATCH 010/181] feat(kmip-1.4): implement CreateSplitKey and
 JoinSplitKey for KMIP 1.4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both operations are defined in KMIP 1.4 spec (§4.38 and §4.39) but were
missing correct struct definitions and 1.4↔2.1 conversion impls.

Changes:
- Fix CreateSplitKey 1.4 struct: add object_type (required), optional
  unique_identifier (key to split), rename parameter→prime_field_size
- Fix CreateSplitKeyResponse 1.4 struct: replace wrong split_key_parts
  field with spec-compliant split_key_unique_identifiers list
- Fix JoinSplitKey 1.4 struct: replace binary split_key_parts data
  with spec-compliant object_type + split_key_unique_identifiers list
- Add From (1.4→2.1): maps optional UID to empty
  TextString when absent (server generates a new key)
- Add TryFrom (2.1→1.4)
- Add From (1.4→2.1): split_key_method defaults to XOR
  (overridden by handler after reading the stored shares)
- Add TryFrom (2.1→1.4)
- Wire CreateSplitKey and JoinSplitKey into the Operation TryFrom
  conversions (both 1.4→2.1 and 2.1→1.4 directions)
- Add 4 new round-trip and conversion tests in kmip_1_4_tests.rs

All 214 kmip tests and 32 key ceremony tests pass.

Subject: [PATCH 011/181] fix(wizard): remove dead fields from AuthWizardResult
 and wire auth_verifier

http_api_token was always None (token written directly into HttpConfig).
ui_config_oidc was already applied inside configure_auth via ui.ui_oidc_auth.
auth_verifier was built but never wired into ClapConfig by the caller.

- Remove http_api_token and ui_config_oidc from AuthWizardResult
- Remove all #[allow(dead_code)] suppressions
- Wire auth_verifier: auth_result.auth_verifier into ClapConfig in mod.rs

Subject: [PATCH 012/181] fix(ui): gate CO revoke UI on is_crypto_officer +
 sync log-reference.md
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The disable-btn was rendered for any user when ceremony_activated && users.length > 0,
causing the unit test to fail:
  CryptoOfficerRevoke.test.ts:93 – non-active CO saw disable-btn (expected null)

Fix: condition changed to ceremony_activated && is_crypto_officer so only the
currently active CO sees the revoke section (self-revoke or peer-revoke via
the target selector). Dormant CO candidates can still call the backend API.

Also sync log-reference.md: one log message in kms_client changed wording.

Subject: [PATCH 013/181] docs(get-attrs): fix stale comment about SplitKey
 stored Attributes

The comment claimed crypto metadata (algorithm, length, format) is NOT
duplicated into the stored Attributes. This is wrong: create_split_key.rs
sets cryptographic_algorithm, cryptographic_length, and key_format_type in
share_attrs and passes them to database.create at creation time.

The overlay code in get.rs is a valid defensive fallback for:
- SplitKey objects imported via KMIP without explicit attributes
- Attributes cleared by DeleteAttribute
- Any pre-fix objects in existing databases

Updated the comment to accurately describe the fallback purpose.

-Cryptographic Risk Scorer & Report Generator
-==============================================
-Reads the findings.json produced by scan_source.py (and optionally
-cargo audit --json for CVE data) and produces:
-  • risk_report.json  — machine-readable risk report with prioritized findings
-  • crypto_report.md  — Markdown fragment (sensor run details)
-  •      — complete crypto_inventory.md MkDocs page (if --docs-output given)
-
-Usage:
-    python3 risk_score.py \\
-        --input findings.json \\
-        --output-json risk_report.json \\
-        --output-md  crypto_report.md \\
-        [--project-name "My Project"] \\
-        [--audit-json cargo_audit.json] \\
-        [--docs-output documentation/docs/certifications_and_compliance/audit/crypto_inventory.md]

-# ── KMIP / runtime policy — combined mitigation map ──────────────────────────
-#
-# Two complementary layers determine whether a scanner finding is "mitigated":
-#
-#  Layer 1 — Runtime algorithm policy (algorithm_policy.rs deny-list)
-#    Any algorithm explicitly denied by algorithm_policy.rs cannot be reached
-#    through any KMIP operation.  All source hits for those algorithms are
-#    therefore "blocked by runtime policy" regardless of which file they appear
-#    in.
-#
-#  Layer 2 — Source-location context (KMIP spec / protocol / test code)
-#    Some algorithms (EC-P192, RSA-1024, SHA-1 in OAEP) are not in the deny-list
-#    because the KMIP spec requires supporting them as enum values or because
-#    NIST SP 800-131A Rev. 2 explicitly permits them in specific contexts
-#    (RSAES-OAEP w/ SHA-1 for legacy key unwrapping, Acceptable ≠ Recommended).
-#    These hits are mitigated by documenting their exact protocol context.
-#
-# Result: all current CRITICAL and HIGH findings are fully mitigated.

-# =============================================================================
-# Cosmian KMS — Runtime Network Security Analyser
-# =============================================================================
-# Performs a comprehensive black-box security assessment of a running KMS
-# server using exclusively open-source tools available on any modern Linux:
-#
-#   • openssl s_client  — cipher suite negotiation, cert chain, protocol versions
-#   • curl              — HTTP security headers, HSTS, CORS, Content-Security-Policy
-#   • nmap (optional)   — port scan, TLS NSE scripts (nmap --script ssl-*)
-#   • sslyze (optional) — deep TLS analysis, certificate transparency, OCSP
-#   • nuclei (optional) — template-based vulnerability scanning
-#   • Custom Python     — KMIP protocol tests, rate-limit probes, auth checks
-#
-# Usage:
-#   bash .mise/scripts/audit/runtime_security.sh --server-url https://HOST:PORT \
-#       [--cert certs/client.pem] [--key certs/client.key] [--ca certs/ca.pem] \
-#       [--output-dir /tmp/runtime-] [--report] [--insecure]
-#
-# Options:
-#   --server-url     KMS server URL (required, e.g. https://localhost:9998)
-#   --cert          Client TLS certificate (for mTLS tests)
-#   --key           Client TLS private key (for mTLS tests)
-#   --ca            CA certificate for server verification
-#   --output-dir    Output directory (default: cbom/runtime/ — overwritten on each run)
-#   --report        Write Markdown report (default: stdout summary only)
-#   --insecure            Skip server cert verification (dev environments)
-#   --help                Show this help
-#
-# Exit code: 0 = all checks PASS;  1 = critical finding(s);  2 = tool error

-## 🔒 FIPS 140-3 Compliance
-
-**Score: 49%** of detected algorithm references are FIPS 140-3 approved.
-
-The remaining 51% are:
-
-| Category | Reason |
-|----------|---------|
-| PKCS#11 / HSM | FIPS status depends on the certified HSM hardware |
-| Covercrypt ABE | Attribute-based encryption — FIPS not applicable |
-| ChaCha20-Poly1305 | Non-FIPS builds only (`--features non-fips`) |
-| KMIP 1.4 legacy enums | Type definitions — not active crypto operations |
-
-!!! success "FIPS build mode"
-    `cargo build` (without `--features non-fips`) exercises **only FIPS 140-3
-    approved algorithms** at runtime.
-
----
-
-## 🛡️ Memory Safety — Zeroize Discipline
-
-The sensor found **204 references** to `Zeroizing` / `ZeroizeOnDrop`
-across the codebase — automatic key-material zeroing on drop (CWE-316 mitigation).
-
-!!! success "Best practice implemented"
-    All derived key material (HKDF, PBKDF2) and private key bytes are wrapped in
-    `Zeroizing>` — secrets are scrubbed from memory when their scope ends.

-| Layer | Tool | What it discovers |
-|-------|------|-------------------|
-| Source code | `scan_source.py` | Algorithm usage, deprecated primitives, weak keys, hardcoded material, PQC/zeroize |
-| Dependency tree | `cdxgen` (OWASP CycloneDX) | Cryptographic library versions from `Cargo.lock` |
-| CVE feed | `cargo audit` (RustSec) | Known vulnerabilities in crypto dependencies |
-| Live TLS | `testssl.sh` (optional) | Cipher suites, certificate chain, TLS version |
-
-The sensor outputs a **Cryptographic Bill of Materials (CBOM)** in CycloneDX 1.6 format
-(see [`cbom/cbom.cdx.json`](../../../cbom/cbom.cdx.json)).

-## ▶️ How to Run
-
-??? tip "Full scan — source + CVE + CBOM (also updates this page)"
-    ```bash
-    bash .mise/scripts/audit/crypto_sensor.sh --repo-root .
-    # With live TLS scan:
-    bash .mise/scripts/audit/crypto_sensor.sh \\
-        --repo-root . --server-url https://localhost:9998 --update-cbom
-    ```
-
-??? tip "Source scanner only (fast, no network)"
-    ```bash
-    python3 .mise/scripts/audit/scan_source.py \\
-        --repo-root . --output /tmp/findings.json
-    ```
-
-??? tip "Risk scorer + page regeneration"
-    ```bash
-    python3 .mise/scripts/audit/risk_score.py \\
-        --input /tmp/findings.json \\
-        --output-json /tmp/risk_report.json \\
-        --docs-output documentation/docs/certifications_and_compliance/audit/crypto_inventory.md
-    ```
-
-Output files are written to `cbom/sensor/` (stable path — overwritten on each run):
-
-| File | Content |
-|------|---------|
-| `findings.json` | Raw per-line source scanner findings |
-| `risk_report.json` | Risk-scored findings + CVE data |
-| `cargo_audit.json` | CVE advisory data |
-| `dep_cbom.json` | Dependency-level CBOM (cdxgen) |
-| `tls_report.txt` | TLS scan output (if `--server-url` was given) |

-### 1.1 In-scope components
-
-| Component | Technology | Risk level |
-|-----------|-----------|------------|
-| KMS server binary (`cosmian_kms`) | Rust (Actix-web, tokio) | Critical |
-| KMIP protocol engine (`cosmian_kmip`) | Rust | High |
-| JWT/JWKS authentication middleware | Rust (jsonwebtoken, reqwest) | High |
-| Database backends (SQLite, PostgreSQL, Redis-findex) | Rust (sqlx, redis) | High |
-| CLI client (`ckms`) | Rust (clap) | Medium |

-
-### 1.2 Out of scope
-
-- Physical HSM devices (Utimaco, Proteccio, Crypt2Pay) — covered by vendor certifications
-- Third-party cloud services (AWS XKS, Azure EKM, GCP CMEK) — covered by cloud-provider SLAs
-- Infrastructure layer (OS, network) — covered by deployment hardening guides
-
-### 1.3 Methodology
-
-This audit combines:
-
-1. **Automated static analysis** — `cargo audit`, `cargo deny`, `semgrep`, `gitleaks`, `grep`-based pattern checks (orchestrated by `.mise/scripts/audit/multi_framework.sh`)
-2. **Manual code review** — targeted review of authentication, cryptographic key handling, input parsing, and inter-service communication paths
-3. **Integration testing** — Rust `#[test]` modules in `crate/clients/clap/src/tests/security/` and `crate/server/src/middlewares/jwt/jwks.rs`
-4. **Control gap analysis** — mapping findings to each framework's control catalogue
-

-
-### 5.1 Assurance level mapping
-
-| Level | Requirement | KMS evidence |
-|-------|-------------|-------------|

-## 6. OSSTMM
-
-The Open Source Security Testing Methodology Manual (OSSTMM) defines five security channels: **Human, Physical, Wireless, Telecommunications, Data Networks**. The KMS is primarily a data-network application.
-
-### 6.1 Data Networks channel
-
-| OSSTMM section | Test area | Finding | Status |
-|----------------|-----------|---------|--------|
-| 5.1 — Posture | Server does not broadcast version by default | Confirmed: no `Server:` header in default config | ✅ |
-| 5.3 — Enumeration | KMIP endpoint returns 422 (not 404) for invalid bodies | `curl -X POST -d '{}' .../kmip/2_1` → 422 | ✅ |
-| 5.4 — Visibility | Sensitive fields masked in debug output | DB URL password → `****`; TLS passphrase masked | ✅ |
-| 5.6 — Access | CORS headers do not reflect attacker origin | CORS tests `cors_config.rs` (C1–C3) confirm | ✅ |
-| 5.7 — Trust | JWKS source must use HTTPS | `validate_jwks_uris_are_https()` enforced at startup | ✅ |
-| 5.8 — Controls | SSRF via open redirect blocked | `Policy::none()` on JWKS client; SR1 test confirms | ✅ |
-| 5.10 — Process | Batch request count mismatch handled gracefully | Batch abuse tests B1–B5 in `batch_abuse.rs` | ✅ |
-| 5.11 — Configuration | No wildcard CORS; no hard-coded credentials | Code scans pass; `deny.toml` bans enforced | ✅ |

-### 6.2 Residual risk summary
-
-| Risk area | Residual risk | Mitigation |
-|-----------|--------------|------------|
-| MFA enforcement | Low–Medium | Depends on OIDC provider configuration |
-| SQLite backup integrity | Low | WAL mode; deployment guide recommends periodic backups |
-| Rate limiting | Low | Not implemented at KMS level; recommend reverse-proxy (nginx, Caddy) |
-| Side-channel attacks | Very low | FIPS provider; constant-time primitives via OpenSSL |

-# Runtime Network Security Audit
-
-!!! abstract "Scope"
-    This report documents the **live runtime security assessment** methodology and expected results for the Eviden KMS server.
-    The analysis targets the running server process over the network — complementing [static source analysis](owasp_security_audit.md)
-    and [multi-framework compliance](multi_framework_security_audit.md) reports.
-
-    Run the analyser with:
-    ```bash
-    bash .mise/scripts/audit/runtime_security.sh \
-        --server-url https://HOST:PORT \
-        [--cert client.pem] [--key client.key] [--ca ca.pem]

-        KMS->>DB: Look up access control for user
-        KMS-->>CLI: KMIP Response
-    ```
-
-=== "Auth modes"
-
-    | Mode | How it works | When to use |
-    |---|---|---|
-    | **mTLS** | Client presents X.509 certificate signed by trusted CA | Internal services, CLI tooling |
-    | **JWT (OAuth2)** | Bearer token from Auth0 / Keycloak / OIDC provider | Web UI, end-user access |
-    | **API key** | Shared secret in header | Machine-to-machine, simple integrations |
-    | **No auth** | Disabled — dev/test only (`--auth-type none`) | Local development only |
-
-    !!! warning
-        Never deploy with `--auth-type none` in production.
-        The KMS must enforce at least one authentication method on all KMIP routes.
-
-=== "mTLS test"

-    # Test mTLS with ckms-generated certs
-    bash .mise/scripts/audit/runtime_security.sh \

- access.rs: correct stale CryptoOfficerConfig doc that claimed 'No
  cryptographic use' — active CO can Encrypt/Decrypt/Sign/MAC/Hash
  (CO candidate is already Operator; promotion must not reduce rights).
  Document blast radius: active CO is a global crypto oracle, all
  accesses audit-logged at ERROR target=audit.

- permissions.rs: document the peer-revocation trust model — dormant
  candidates can revoke active COs deliberately (break-glass path:
  prevents a situation where a compromised active CO cannot be revoked
  because no other active CO exists). No behavior change.

- CHANGELOG/feat_split_key.md: remove false claim that activation errors
  are 'propagated with ?'. Auto-activation is intentionally non-fatal:
  key is stored unconditionally; failures are WARN-logged with a pointer
  to the manual activation endpoint (fail-secure).

The server rejects activation only when ALL shares belong to the activating
candidate (solo self-activation guard). It does not require the candidate to
own zero shares. Align key_ceremony.md step 6 and the CryptoOfficerActivate
doc comment to reflect the real invariant.

GrantAccess and RevokeAccess are custom server routes, not KMIP operations.
They are owner-scoped: only the object owner can manage ACLs on their objects.
The CO ownership bypass does not extend to ACL management on foreign objects.
Remove them from the CO column and add an explanatory note.

MIME-Version: 1.0

The 'live divergence' between Destroy and Revoke observed in testing is a
probe-methodology artefact: Destroy silently skips objects the caller cannot
destroy (continue → 200 with count=0), while Revoke returns Unauthorized.
Both call user_can_perform_operation, which includes the CO bypass for active
COs on non-HSM objects. Add a comment making this semantic difference explicit.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PM-2: dormant CO candidates (listed but not yet ceremony-activated) pass
enforce_create_permission by design — they need Create/Import to complete the
ceremony prerequisite (ceremony vicious-circle break).

PM-3: Rekey routes through this gate because it creates a new Managed Object.
When crypto_officer.users is configured, object ownership alone does not grant
Rekey — the asymmetry vs Destroy/Revoke/SetAttribute is intentional.

Subject: [PATCH 030/181] fix(dispatch): route CO lifecycle ops through
 enforce_create_permission explicitly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CreateKeyPair, Register, ReKeyKeyPair, CreateSplitKey, JoinSplitKey have no
KmipOperation enum variant. The CryptoOfficer arm was falling through to an
implicit Ok(()) for these tags — undocumented and unaudited. Route them through
enforce_create_permission (same as the Operator arm) to make the allow path
explicit, consistent, and auditable. Active COs always satisfy this gate since
they are listed in crypto_officer.users.

Addresses PB-1 from PR #991 review.

Subject: [PATCH 031/181] docs(locate): clarify CO ownership bypass behavior
 for Locate (PM-6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The find_all vs find swap at the top of locate() is a real CO ownership bypass:
active COs receive all matching objects regardless of ownership/grants, while
non-COs only see owned/granted objects. The bypass only manifests as a
difference in the *returned UID list* — not in exit code — so testing requires
diffing result sets across callers, not just checking success.

Addresses PM-6 from PR #991 review.

The ownership bypass (user_can_perform_operation) covers KMIP key-lifecycle
operations only. Crypto operations (Encrypt/Decrypt/Sign/…) route through
is_owm_authorized_with_get_wildcard, which checks ownership or explicit grants
and has no CO bypass. The previous doc claimed 'global encrypt/sign/decrypt
oracle' combined with ownership bypass — this was incorrect. An active CO can
only use crypto ops on keys they own or have been explicitly granted.

Subject: [PATCH 033/181] fix(ceremony): elevate split-key share audit logs to
 ERROR, add session_id correlation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F-6: upgrade CreateSplitKey share-stored log and ceremony source-key
destruction log from info!() to tracing::error!(target: 'audit', ...)
so that split-key events are captured by SIEM/audit sinks regardless of
the runtime log level filter (CWE-778 Missing Logging of Critical
Operations).

F-7: fix misleading 'currently a no-op' doc comment on
CryptoOfficerConfig::validate() — the n>=3 guard was already enforced
by co.validate() in server_params.rs; only the doc was stale.

F-8: generate a UUIDv4 ceremony_session_id before the share loop in
create_split_key() and stamp it on every share audit entry, enabling
cross-share correlation in audit logs. Generate a join_session_id in
join_split_key() for the same reason.

Update log-reference.md with new error-level audit entries and their
variable/notes documentation.

Subject: [PATCH 034/181] fix(ceremony): F-2 + F-3 + F-9 security fixes for CO
 split-key ceremony
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F-9 — Enforce activated_by uniqueness in crypto_officer_activations:
- query.sql (PostgreSQL): add `activated_by VARCHAR(255)`, update INSERT,
  add partial unique index: CREATE UNIQUE INDEX ON (activated_by) WHERE revoked_at IS NULL
- query_mysql.sql: add column, update INSERT, add migration queries;
  uniqueness enforced at application layer (MySQL lacks partial-index support)
- PermissionsStore trait: add `activated_by: &str` to
  `activate_crypto_officer_ceremony()`
- sqlite.rs / pgsql.rs / mysql.rs: idempotent startup migration (ALTER TABLE),
  pass `activated_by` through to the INSERT
- redis_with_findex.rs: pass `activated_by` (captured in sealed payload)
- database_permissions.rs: thread `activated_by` from join_split_key caller
- pgsql.rs tests: strip `postgresql://credentials@` from test fixtures so
  lychee does not fail on comma-separated multi-host port strings
- lychee.toml: exclude Ubuntu manpages + ETSI (flaky/bot-blocking); remove
  stale workaround entries (root cause fixed in test fixtures)

F-2 — Compensating delete when CO ceremony activation fails:
- In JoinSplitKey: when `perform_crypto_officer_ceremony_activation` fails,
  delete the just-stored reconstructed key (`kms.database.delete`)
- Log the rollback at `error!(target="audit")` with session_id, uid, error
- If the delete itself fails: log a second CRITICAL audit event for SIEM
- Return `Err(e)` — JoinSplitKey fails atomically; orphan prevention

F-3 — Optional AES-KW share wrapping via ceremony_wrapping_key_id:
- `CryptoOfficerConfig.ceremony_wrapping_key_id: Option`
- CLI flag: `--ceremony-wrapping-key-id` / env: `KMS_CEREMONY_WRAP_KEY_ID`
- Wired through `RolesConfig` → `CryptoOfficerConfig` in server_params
- CreateSplitKey: retrieves AES wrapping key, RFC 5649 wraps each share's
  bytes before DB storage, stamps `x-cosmian-share-wrapping-key` attr
- JoinSplitKey: detects attribute, unwraps bytes before XOR reconstruction
- `extract_key_bytes` promoted to `pub(crate)` for reuse in JoinSplitKey
- `Box::pin(create_split_key(...))` at call-site (future size limit)
- key_ceremony_tests.rs: add `ceremony_wrapping_key_id: None` to structs

 # CHANGELOG — feat/split_key
 
-## Features — Key Ceremony (XOR n-of-n split knowledge)
-
-- **Split-key ceremony for Crypto Officer role** (NIST SP 800-57 Part 2 Rev 1 §4.6 split knowledge):
-  `CreateSplitKey` and `JoinSplitKey` KMIP 2.1 operations implement XOR-based secret sharing.
-  All $n$ shares are required to reconstruct; threshold always equals total parts (n-of-n scheme).
-- **Config-driven ceremony**: `[roles]` section gains `crypto_officer_require_ceremony`, `ceremony_secret`
-  (hex-encoded 32-byte AES-256 key for GCM sealing), `crypto_officer_users`. When enabled, ceremony
-  candidates are inactive until all shares are joined via `JoinSplitKey`.
-- **Automatic share tagging**: shares created by ceremony candidates carry `x-cosmian-crypto-officer-ceremony`
-  vendor attribute tag for automatic ceremony detection.
-- **Active record management**: `crypto_officer_activations` table persists ceremony records with
-  sealed payload (AES-256-GCM via KDF-derived keys), activated\_by/participants/key\_hash tracking,
-  revoke support with `revoked_at`/`revoked_by`.
-
-## Security Improvements
-
-- **Zeroization of key material**: `xor_split` / `xor_join` now use `Zeroizing>` throughout;
-  heap memory wiped on drop. Shares consumed via `into_iter()` (no clone), leaving a single
-  zeroized copy. Derived `CeremonyKeys.obfuscation_key` zeroed on drop via explicit `Drop` impl.
-- **`ceremony_secret` never logged**: custom `Debug` impl for `RolesConfig` masks `ceremony_secret`
-  as `""`; prevents secret exposure when `RUST_LOG=debug`.
-- **Compensating delete on activation failure**: `JoinSplitKey` now deletes the reconstructed
-  key from the DB when ceremony auto-activation fails, then returns the error.  Previously the failure
-  was non-fatal and the key persisted without an activation record — any user holding a Grant on the
-  resulting UID could access it, bypassing ceremony dual-control.  A second CRITICAL audit entry is
-  emitted if the compensating delete itself fails, enabling SIEM alerting.
-- **Optional AES-KW share wrapping at rest**: new config field `ceremony_wrapping_key_id`
-  (CLI `--ceremony-wrapping-key-id` / env `KMS_CEREMONY_WRAP_KEY_ID`).  When set, `CreateSplitKey`
-  wraps each share's bytes with the referenced AES key using RFC 5649 (NIST SP 800-38F) before writing
-  to the DB.  `JoinSplitKey` detects the `x-cosmian-share-wrapping-key` vendor attribute and unwraps
-  transparently.  When the KMS is HSM-backed, the wrapping key can be HSM-resident, providing
-  hardware-boundary protection equivalent to purpose-built HSM split-key solutions.
-- **Split-key audit logs elevated to ERROR**: `CreateSplitKey` share-stored and source-key
-  destroyed events, and the `JoinSplitKey` reconstructed-key-stored event, now emit at
-  `error!(target="audit")`.  This ensures they are captured by SIEM/audit sinks regardless of the
-  runtime `RUST_LOG` filter (CWE-778 mitigation).
-- **Corrected doc comment on `CryptoOfficerConfig::validate()`**: the method previously said
-  "currently a no-op" but the n≥3 guard was already implemented.  Doc updated to reflect the actual
-  enforced invariant.
-- **Ceremony session ID stamped on audit logs**: a `Uuid::new_v4()` ceremony session ID is
-  generated once per `CreateSplitKey` call and stamped on every audit log entry for that call.
-  Similarly, `JoinSplitKey` generates a join session ID.  This enables SIEM correlation of all shares
-  from a single ceremony split (NIST SP 800-57 Part 2 Rev 1 §4.6 audit requirements).
-- **DB-level uniqueness on `activated_by`**: `crypto_officer_activations` gains an
-  `activated_by VARCHAR(255)` column.  PostgreSQL/SQLite add a partial unique index
-  `WHERE revoked_at IS NULL` (at most one active record per user at DB level).  MySQL enforces at
-  application layer (no partial-index support).  Idempotent startup migrations handle upgrades of
-  existing databases.
-- **Strict permission enforcement on JoinSplitKey**: ceremony activation is attempted as an
-  auto-activation side-effect of `JoinSplitKey`. Activation failure is now **fatal** — the reconstructed
-  key is deleted on failure.
-- **Fail-secure unenrolled users**: when roles are configured, unknown users default to Operator
-  (minimum privilege) instead of unrestricted access (NIST SP 800-57 Part 2 Rev 1 §4.8).
-- **Prevent duplicate active ceremony records**: `activate_crypto_officer_ceremony` revokes prior active
-  records before insert; SELECT uses `ORDER BY activated_at DESC LIMIT 1` for deterministic retrieval.
-- **Complete `key_part_identifier` validation**: join verifies identifiers are unique and form `{1..=N}`,
-  preventing duplicate-share attacks that would produce garbage reconstructed keys.
-- **Explicit `UniqueIdentifier` handling**: `unwrap_or_default()` replaced with match on
-  `TextString` variant; non-text UIDs return clear `KmsError::InvalidRequest`.
-
-## Features — Role Model (Two-Role RBAC)
-
-- **Two-role model**: `Operator` (default, read/write crypto ops) and `CryptoOfficer`
-  (lifecycle + ownership bypass). Replaces earlier three-role design.
-- **CryptoOfficerConfig**: simplified from former multi-role structs; fields are
-  `users`, `require_ceremony`, `ceremony_secret` — no longer includes `total_parts` (removed as dead code).
-- **`UserId` type safety**: dedicated newtype wrapping `String` with `From<&str>`, `Deref`,
-  `PartialEq` for `&str`/`String`, plus `try_new()` rejecting empty strings. Serde derives added.
-- **`ObjectHandle<'a>` enum**: typed object ID classifier with `is_hsm()`, `hsm_parts()`, prefix matching
-  replacing the removed `has_prefix()` utility; used consistently across dispatch/permissions/HSM paths.
-
-## CLI (`ckms`)
-
-- `ckms access-rights crypto-officer status` — print CO role configuration and ceremony state
-  (`GET /access/crypto-officer/status`).
-- `ckms access-rights crypto-officer disable` — revoke active CO ceremony (requires active CO).
-- Docs updated in `documentation/docs/kms_clients/main_commands.md` (heading levels fixed, trailing
-  whitespace removed).
+## Features
+
+### Two-role RBAC (CryptoOfficer / Operator)
+
+Replaces the former `privileged_users` flat list with two FIPS 140-3 aligned roles:
+
+- **`Operator`** (default) — crypto-use ops: Encrypt, Decrypt, Sign, Verify, MAC, Hash, Locate, GetAttributes.
+- **`CryptoOfficer`** — key-lifecycle ops + ownership bypass: Create, Import, Certify, Rekey, Activate, Revoke, Destroy, Get, Export, SetAttribute, …
+- Unknown users default to `Operator` (fail-secure, NIST SP 800-57 Pt 2 §4.8).
+- New `[roles]` TOML section; migration: rename `privileged_users` → `crypto_officer_users` under `[roles]`.
+
+### Split-key ceremony (XOR n-of-n)
+
+`CreateSplitKey` and `JoinSplitKey` KMIP 2.1 (and 1.4) operations implement XOR n-of-n secret sharing:
+
+- Shares tagged `x-cosmian-crypto-officer-ceremony`; each owned by a different CO candidate.
+- `JoinSplitKey` with all ceremony shares auto-activates the CO role (writes `crypto_officer_activations`).
+- Activation records AES-256-GCM sealed from `ceremony_secret` (hex 32-byte); `ceremony_secret` masked in logs.
+- **Optional AES-KW share wrapping** (`ceremony_wrapping_key_id` / `KMS_CEREMONY_WRAP_KEY_ID`): each share encrypted with RFC 5649 before DB write; unwrapped transparently on `JoinSplitKey`. HSM-backed key supported.
+- `ceremony_key_id` (`KMS_CEREMONY_KEY_ID`) accepted by config parser for future KMS-object sealing key (ADP-26, not yet functional — use `ceremony_secret` in the meantime).
+
+### Revocation
+
+- **Self-revoke**: active CO calls `POST /access/crypto_officer/disable`.
+- **Peer revocation**: any CO candidate calls the same endpoint with `{ "target_user": "" }` to demote another active CO without server restart (NIST SP 800-152 FR:6.119).
+
+## Security
+
+- Zeroized key material throughout (`Zeroizing>`, `Drop` on `CeremonyKeys`).
+- **Compensating delete on activation failure**: reconstructed key deleted from DB if auto-activation fails; CRITICAL audit entry if the delete itself fails (prevents bypass via failed ceremony).
+- Audit events for `CreateSplitKey`/`JoinSplitKey` elevated to `error!(target="audit")` (CWE-778 mitigation).
+- Per-call session UUID stamped on all ceremony audit entries for SIEM correlation.
+- DB partial unique index on `activated_by WHERE revoked_at IS NULL` (PostgreSQL/SQLite); application-level guard on MySQL.
+- Complete `key_part_identifier` validation: shares must form `{1..=N}` with no duplicates.
+- Ceremony candidates exempted from `Create`/`Import` restriction before ceremony completes (prevents bootstrap deadlock).
+
+## CLI
+
+- `ckms access-rights crypto-officer status` — show role config and ceremony state.
+- `ckms access-rights crypto-officer disable` — revoke active ceremony.
+- New `create-split-key` subcommand under the `crypto-officer` CLI group.
 
 ## Web UI
 
-- **Crypto Officer page** (`/ui/access-rights/crypto-officer`): status page showing role config,
-  ceremony activation state, CO user list, and Disable button (visible only when active ceremony exists;
-  requires active CO privileges). Menu label shortened from "Crypto Officer Role" to "Crypto Officer".
-- **Crypto Officer page fully localized**: all labels, descriptions, badges, tooltips, and ceremony
-  workflow steps are now translated via i18n, including Chinese (`zh-CN`). The menu entry
-  "Crypto Officer" is also localized.
-- **Split Key and Join Split Key pages localized and kept generic**: both dialogs
-  (`/ui/sym/keys/split` and `/ui/sym/keys/join`) render their headings, descriptions, labels,
-  placeholders, validation messages, and result text via i18n (English and Chinese). They no longer
-  reference the key ceremony or Crypto Officer role — the share count is always user-editable. The
-  corresponding "Split"/"Join" menu entries are also localized.
-- **Search Objects locate buttons across action forms**: key/object/certificate identifier inputs in
-  symmetric, RSA, EC, Covercrypt, MAC, PQC, FPE, certificate, attribute, object, and rotation-policy
-  dialogs now use the reusable `KeyIdInput` component so users can search and select existing objects
-  directly from the form, with object-type filtering where applicable.
-- **SplitKey / JoinSplitKey dialogs**: removed unsupported "Polynomial Sharing GF(2^8)" (Shamir) option;
-  now defaults to XOR method. **Threshold (k) input removed** and **method selector removed** —
-  only XOR n-of-n is supported. Renamed "Total Parts" to "Number of Shares". Updated descriptions
-  to clarify all shares are required.
-- **JoinSplitKey dialog**: method selector removed (XOR is the only option). Description updated
-  to clarify all shares are required for n-of-n reconstruction.
-- **Dark theme aligned with the documentation site**: the Web UI dark theme now reuses the same
-  mdBook "navy" palette as `docs.cosmian.com` (near-black `#161923` background, `#bcbdd0` text,
-  `#282d3f` sidebar) instead of the previous gray surfaces. The light theme uses the darker brand
-  orange `#c73f1b` for the primary accent. The sidebar menu and all surfaces now switch together
-  with the light/dark toggle.
-- **Contrast fixes (WCAG AA)**: resolved unreadable colour combinations in dark mode — dark text on
-  the black background (`text-gray-800`, `text-blue-800`, `text-red-800`), light-gray helper text on
-  white, near-invisible borders, and the low-contrast orange/teal accents — now meet AA contrast in
-  both themes.
-
-## Bug Fixes
-
-- **Ceremony candidate exemption extended to Create/Import**: ceremony candidates (users in
-  `crypto_officer_users` with `require_ceremony = true`) can now create and import keys before
-  completing the ceremony. Previously only `CreateSplitKey`/`JoinSplitKey` were exempted, causing
-  a chicken-and-egg problem where candidates could not create the master key to split.
-  The exemption remains scoped to ceremony candidates only — full CO privileges (ownership bypass)
-  still require ceremony completion.
-- **Missing test data restored**: re-added deleted config files in `test_data/configs/server/client/`
-  (`auth_plain*.toml`, `jwt.toml`) required by integration tests (`test_kms_all_authentications`,
-  `test_vendor_id_in_vendor_attributes`).
-- **Lychee exclude patterns added**: example OAuth URLs in config templates excluded from link checking.
-  Non-routable IP `1.2.3.4` (used in forward proxy tests) excluded from link checking.
+- **Crypto Officer page**: status dashboard (ceremony state, active CO list, custodian count); configurable base key ID with live share-UID preview (`#1`, `#2`…); peer-revocation dropdown (visible to active CO only); ceremony activation form.
+- **SplitKey / JoinSplitKey dialogs**: Shamir option removed; only XOR n-of-n supported. "Total Parts" renamed to "Number of Shares". Threshold and method selectors removed.
+- **Dark theme**: aligned to mdBook Eviden palette (`#161923` bg, `#bcbdd0` text, `#282d3f` sidebar, orange `#f14611`). All contrast ratios WCAG AA.
+- **Sidebar fixes**: sub-menus visible when sidebar is collapsed; collapse trigger button color corrected in light theme.
 
 ## Testing
 
-- **7 ceremony vector tests**: `create_split_key_xor` round-trip (2-of-2, 3-of-3), `join_split_key_*`
-  variants covering consistency checks, failure scenarios, and full lifecycle activate→disable→deny.
-- **11 RBAC CLI tests** (`rbac_tests.rs`): verify the two-role model per ADR-2026-06-24:
-  CO can create/export/destroy keys; CO **cannot** encrypt/decrypt (Operator-only); Operator can
-  encrypt/decrypt with grant; Operator cannot create/export/destroy keys; CO ownership bypass;
-  Operator needs explicit grant; grant/revoke access flow.
-- **7 RBAC E2E tests** (`rbac-flow.spec.ts`): SplitKey/JoinSplitKey UI loading, access control
-  page smoke tests, grant access flow via UI, Crypto Officer page accessibility.
-- Server config TOMLs: `cert_auth_crypto_officer.toml`, `cert_auth_crypto_officer_ceremony.toml`,
-  `cert_auth_operator_only.toml`, `rbac/*.{toml}` for role-separation tests.
-- Pre-commit hook fixes applied: shellcheck SC2329/SC2086/SC2119, Go tab→space normalization,
-  CRLF→LF line endings, Python quote style, trailing whitespace, trailing newlines.
+- 7 ceremony vector tests (2-of-2, 3-of-3 round-trips, failure scenarios, full activate→disable→deny lifecycle).
+- 11 RBAC CLI tests (`rbac_tests.rs`): CO/Operator permission matrix per ADR-2026-06-24.
+- 7 RBAC E2E tests (`rbac-flow.spec.ts`): UI smoke tests for split-key and CO pages.
 
 ## Documentation
 
-- **Key ceremony guide** (`documentation/docs/configuration/authorization/key_ceremony.md`): explains
-  two-role RBAC, XOR n-of-n split knowledge, NIST references (SP 800-57 Pt 2 §4.6–§4.8), Mermaid
-  sequence diagrams for 4-phase ceremony flow, and CLI quick reference.
-- **Authorization reference** (`documentation/docs/configuration/authorization.md`): updated role model,
-  operation tables, permission evaluation order, and normative requirements table.
+- Key ceremony guide: two-role RBAC, XOR n-of-n, NIST references, Mermaid sequence diagrams, CLI quick reference.
+- Authorization reference: updated role matrix, operation tables, permission evaluation order.

SSRF via attacker-controlled CRL Distribution Points in KMIP Validate/Import (COSMIAN-2026-020).

- Add validate_crl_url() in crate/server/src/core/certificate/mod.rs:
  blocks private/loopback/link-local IPs and internal hostnames before
  any network I/O; allows HTTP and HTTPS (RFC 5280 CDPs are typically HTTP).
- Rewrite get_crl_bytes() in crate/server/src/core/operations/validate.rs:
  - Call validate_crl_url() before every HTTP(S) fetch
  - Exempt kms_public_url prefix (server's own CRL endpoint is trusted)
  - Add reqwest::redirect::Policy::none() (no redirect following)
  - Add 30-second request timeout
  - Cap response body at 10 MiB (CRL_MAX_RESPONSE_BYTES)
  - Reject bare filesystem paths and file:// URIs in production
  - Allow file:// in #[cfg(any(test, feature = "insecure"))] for test fixtures
  - Use ? on .send() so network failures stay ClientConnectionError (soft-fail)
- Add kms_public_url param to verify_crls() and get_crl_bytes(); pass from
  both validate_operation() and import_operation() via kms.params
- Add 10 regression tests SR-CRL-01 through SR-CRL-10 covering all vectors
- Add COSMIAN-2026-020 entry to SECURITY.md
- Exclude RFC-1918/link-local test URLs from lychee link checker

+
+**Summary:** Cosmian KMS fetched CRLs from URLs embedded in X.509 CRL Distribution Points (CDPs) during KMIP `Validate` and `Import` operations without applying any SSRF mitigations. The `get_crl_bytes()` function in `crate/server/src/core/operations/validate.rs` accepted arbitrary `http://` URLs (including loopback, private RFC-1918, and link-local addresses), followed HTTP redirects unconditionally, read the full response body without a size cap, and treated non-URL CDP values as local filesystem paths — allowing arbitrary file reads. A secondary vector existed via `file://` scheme URLs, which were explicitly converted to filesystem paths.
+
+This is a separate code path from COSMIAN-2026-009 (Google CSE `original_kacls_url` SSRF); the fix for that advisory did not cover CRL Distribution Point fetches.
+
+**Impact:** A post-authentication attacker with `Validate` or `Import` permission could:
+
+- Probe internal HTTP services reachable from the KMS host (confirmed blind SSRF via PoC on v5.26.0).
+- Access cloud metadata endpoints (e.g. `169.254.169.254`) from cloud-hosted deployments.
+- Read arbitrary local files readable by the KMS process via bare filesystem paths or `file://` URIs.
+- Cause denial of service via a slow or unbounded HTTP response body (no size cap, no timeout).
+
+**Mitigation:** Upgrade to 5.27.0. The fix adds `validate_crl_url()` in `crate/server/src/core/certificate/mod.rs` (HTTPS and HTTP allowed; private, loopback, link-local IPs and internal hostnames rejected), applies `reqwest::redirect::Policy::none()` and a 30-second timeout to the CRL-fetch client, caps responses at 10 MiB, and removes filesystem-path and `file://` CRL resolution in production builds (`file://` remains available in `#[cfg(test)]` only). Ten regression tests (SR-CRL-01 through SR-CRL-10) cover all mitigations.

 /// Retrieves Certificate Revocation List (CRL) bytes from a list of URIs.
 ///
-/// This function takes a list of URIs, which can be either URLs or file paths, and retrieves the
-/// corresponding CRL bytes. The retrieved CRLs are cached to avoid redundant network or file system
-/// access. If a CRL is already cached, it is directly retrieved from the cache.
+/// In production, only `http://` and `https://` URIs are fetched. All other URI
+/// types (bare filesystem paths, LDAP, FTP, …) are rejected to prevent
+/// Server-Side Request Forgery (COSMIAN-2026-010).
 ///
-/// # Arguments
+/// When the `insecure` feature is enabled (or in `#[cfg(test)]` builds),
+/// `file://` URIs are additionally permitted so that integration tests and
+/// air-gapped test environments can load local CRL fixtures without an HTTP
+/// server. **Never enable the `insecure` feature in production.**
 ///
-/// * `uri_list` - A vector of strings representing the URIs from which to retrieve the CRLs.
+/// URLs that begin with `kms_public_url` (the server's own base URL) are
+/// exempted from the SSRF host check: the KMS server may legitimately fetch
+/// its own auto-generated CRL endpoint.
 ///
-/// # Returns
+/// Each HTTP(S) URL is validated against [`validate_crl_url`] before any
+/// network I/O: private/loopback/link-local IP ranges and internal hostnames
+/// are rejected unless covered by the `kms_public_url` exemption above.
+/// HTTP redirects are never followed. Responses are capped at
+/// [`CRL_MAX_RESPONSE_BYTES`] and the request times out after 30 seconds.
 ///
-/// A `KResult` containing a `HashMap` where the keys are the URIs and the values are the corresponding
-/// CRL bytes. If an error occurs during the retrieval process, a `KmsError::Certificate` is returned.
+/// Successfully fetched CRLs are cached in [`CRL_CACHE_MAP`] to avoid
+/// redundant network round-trips within the same server process.
 ///
 /// # Errors
 ///
-/// This function will return an error if:
-/// - The provided URI is invalid.
-/// - There is an error in retrieving the CRL from a URL.
-/// - There is an error in reading the CRL from a file path.
-/// ```
+/// Returns [`KmsError::Certificate`] if:
+/// - A URI uses a non-HTTP(S) scheme or is a bare filesystem path (production).
+/// - The URL targets a private, loopback, link-local, or internal hostname
+///   (and is not the server's own URL).
+/// - The HTTP request fails, times out, or returns a non-2xx status.
+/// - The response body exceeds [`CRL_MAX_RESPONSE_BYTES`].

Subject: [PATCH 056/181] fix(test): use temp file in sr_crl_10 instead of
 test_data submodule

The test relied on test_data/certificates/openssl/prime256v1.crl which is
not available in all CI environments (submodule not checked out for some
jobs). Replace with a self-contained tempfile::NamedTempFile write so the
test is hermetic on every runner. Rephrase inline comment to avoid lychee
false-positive on file:// placeholder text.

 ### `cosmian_kms_server_database`
 

From 41bd94484c740a25cdac787ef3fbda98f86842f3 Mon Sep 17 00:00:00 2001
From: Manuthor 
Date: Wed, 19 Aug 2026 15:43:03 +0200
Subject: [PATCH 057/181] feat: implement auto CRL refresh and persist CRLs in
 DB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- fix(crl): use find_all in find_revoked_certificates so CRL includes
  certs from all users, not just those accessible to the requesting user
- feat(crl): add CO guard at generate_crl entry; audit-log CO bypass
- feat(crl): add KMS::find_active_co() helper (first active CO or None)
- feat(crl): auto-regenerate issuer CRL on certificate revocation when
  kms_public_url is set; uses find_active_co for signer identity;
  errors are warn-logged and never fail the Revoke operation
- feat(db): add crls table (SQLite/PgSQL/MySQL/Redis) with upsert_crl
  and get_crl; table created at server boot alongside all other tables
- feat(crl): persist signed CRL to DB after every generate_crl call
- feat(crl): get_cached_crl loads from DB on cold start (no 404 after
  server restart); public CDP endpoint immediately available
- test(crl): add test_crl_contains_certs_from_all_users — regression
  guard for find_all fix: 3 certs owned by 2 users, CRL must have 3
  entries; reverts to 1 without fix
- fix(lychee): exclude crate/ from link checks to avoid false-positive
  parse errors on multi-host PostgreSQL connection strings in comments
- docs(pki): sync pki.md with auto-CDP injection, public CDP endpoint,
  CO requirement, auto-regen on revoke, DB persistence, kms_public_url
- docs(revoke): remove stale 'revocation reason not maintained' sentence
- docs(tables): add crls table (count 5->6, schema, ERD, Redis note)
- docs(log-reference): add new auto-CRL warn/info/audit log entries

 ## Links between tables
 
 - `objects.id` is referenced by `read_access.id` and `tags.id`: one object can have many access rows and many tags.
 - `objects.wrapping_key_id` points to `objects.id`: a wrapping key is itself an object, and many objects can be wrapped by the same key.
+- `crls.issuer_id` logically references `objects.id` (the CA certificate): one CA has at most one current CRL row.
 - `objects.owner` and `read_access.userid` hold user identifiers.
   Users are authenticated identities and are **not** stored in a dedicated table.
 - `parameters` and `crypto_officer_activations` are standalone and do not reference `objects`.

+```toml

+kms_public_url = "https://kms.example.com"

+The updated CRL is immediately available at the public CDP endpoint:
+
+```http
+GET /public/certificates/{issuer_id}/crl    # no authentication required
+```
+
+If no active CO is found when one is required, the regeneration is skipped and a

+The endpoint returns **404** only if the CRL has never been generated since the
+last server start **and** no CRL is stored in the database.
+
+!!! note "Cold-start behavior"
+    Generated CRLs are persisted in the KMS database (`crls` table) and reloaded
+    on server restart, so the public endpoint continues to serve the last signed CRL
+    without requiring a manual `generate-crl` call after each restart.
+
 ### Authority Information Access (AIA)
 
 The AIA extension (`authorityInfoAccess`, OID 1.3.6.1.5.5.7.1.1) can be added

Subject: [PATCH 059/181] feat(crl): configurable validity, Cache-Control
 headers, background refresh scheduler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements 3 features bringing CRL lifecycle parity with Vault PKI, EJBCA,
AWS Private CA, and DigiCert:

1. Configurable CRL validity (--crl-default-validity-days, default 7).
2. Cache-Control + Expires headers on GET /public/certificates/{id}/crl.
   max-age = next_update - now - 60s. RFC 7234 / DigiCert CDN practice.
3. Background CRL refresh scheduler (spawn_crl_refresh_cron).
   Wakes every crl_refresh_check_hours (default 1). Regenerates CRLs
   expiring within crl_refresh_overlap_hours (default 24).
   Prevents stale CRL windows — analogous to EJBCA Overlap Time.

Also: list_crl_issuers() in all DB backends; 3 new server params;
scheduler wired into start_kms_server.rs.

+# ADR-2026-08-20: PKI / X.509 CRL Generation, Distribution & Auto-Refresh Architecture
+
+## Status
+
+Proposed | **Accepted** | Rejected | Superseded | Deprecated
+
+## Context
+
+The Eviden KMS already supported certificate issuance (KMIP `Certify` operation) and
+revocation (KMIP `Revoke`). However, the revocation data was entirely internal to the KMS
+database. Any PKI relying party (TLS stack, browser, OCSP client) needed a Certificate
+Revocation List (CRL) to enforce revocation, and no such CRL distribution mechanism existed.
+
+Several constraints drove the design:
+
+- **RFC 5280 §3 / §5**: CRL Distribution Point (CDP) URIs embedded in certificates must be
+  reachable by unauthenticated relying parties. The KMS cannot require OAuth2/JWT credentials
+  for a CDP endpoint.
+- **RFC 5280 §5.2.3**: CRL Number extensions must be monotonically increasing across CRL
+  generations, including across server restarts.
+- **FIPS 140-3**: CRL signing must use only FIPS-approved algorithms. Authority Key
+  Identifier construction was previously relying on `EVP_sha1()` (not FIPS-approved for new
+  use) and had to be replaced.
+- **Multi-CA**: the KMS can host multiple independent CAs. The solution must be per-issuer,
+  not global.
+- **Operator UX**: operators must be able to configure a public-facing `kms_public_url` and
+  have CDP URIs auto-inserted into newly issued certificates without manual configuration.
+- **Cold-start availability**: the public CDP endpoint must be immediately available after a
+  server restart without requiring a manual `generate-crl` call.
+- **Access control**: because CRL generation enumerates *all* revoked certificates regardless
+  of ownership (bypassing user filters), it must be gated behind the Crypto Officer role when
+  CO users are configured.
+
+## Decision
+
+Implement a three-tier CRL architecture:
+
+### Tier 1 — Authenticated CRL generation endpoint
+
+`GET /certificates/{issuer_id}/crl` (requires authentication)
+
+- Signs a fresh X.509 v2 CRL using the CA's private key from the KMS key store.
+- Lists all certificates with `CertificateLink → issuer_id` and KMIP state `Deactivated` or
+  `Compromised`, regardless of owner (CO-only bypass).
+- Supports `format=der` (default, `application/pkix-crl`) and `format=pem`
+  (`application/x-pem-file`) query parameters.
+- Supports `validity_days` override (server default: 7 days, never < 1).
+- Uses a process-global atomic counter seeded from UTC Unix timestamp as CRL Number, guaranteeing
+  monotonic uniqueness across concurrent calls and server restarts.
+- Writes the signed CRL DER and `next_update` timestamp to the `crls` database table
+  (non-fatal on DB error — in-memory cache still works).
+- Populates a process-local `GENERATED_CRL_CACHE` (`LazyLock>>`) for fast re-serving.
+- Also exposed as a new CLI command `ckms certificates generate-crl` and Web UI action
+  (Certificates → Certs → Generate CRL).
+
+### Tier 2 — Unauthenticated public CDP endpoint
+
+`GET /public/certificates/{issuer_id}/crl` (no authentication)
+
+- Serves pre-signed CRL DER bytes from the two-level cache (in-memory → DB fallback).
+- Returns HTTP 404 with a diagnostic message until the cache is primed.
+- Sets `Last-Modified` (RFC 7231 IMF-fixdate) and `Content-Disposition` headers.
+- Intended as the CDP URI in `crlDistributionPoints` extensions: `{kms_public_url}/public/certificates/{issuer_id}/crl`.
+- Does **not** sign fresh CRLs — it only serves the last signed bytes; no key material is
+  accessed on this path.
+
+### Tier 3 — Scheduled CRL auto-refresh
+
+A background cron task (`spawn_crl_refresh_cron`) wakes every `crl_refresh_check_hours`
+(default: 24 h, 0 = disabled) and regenerates any stored CRL whose `next_update` timestamp
+falls within `crl_refresh_overlap_hours` (default: 48 h) of the current time.
+
+This models the *CRL overlap window* pattern (EJBCA "CRL Overlap Time", AWS PCA 1-day overlap):
+the new CRL is signed before the old one expires, so relying parties always have a valid CRL
+even if no revocation event triggered a manual regeneration.
+
+The cron runs in its own OS thread with a single-threaded Tokio runtime to avoid contention
+with the main Actix-web executor. It is shut down cleanly via a `oneshot::Sender<()>` held by
+the server startup routine.
+
+### Tier 4 — Auto-injection of CDP extension
+
+When `kms_public_url` is configured, the `Certify` operation automatically inserts a
+`crlDistributionPoints` extension (RFC 5280 §4.2.1.13) pointing to the public CDP endpoint
+into newly issued non-self-signed certificates, unless the subject or the caller already
+provides a CDP.
+
+Self-signed certificates receive `id-ce-noRevAvail` (RFC 9608) instead, since self-signed
+certs cannot appear in a CRL they also sign.
+
+Re-certifications that already carry a CDP are not modified.
+
+### FIPS-safe AKI construction
+
+The `AuthorityKeyIdentifier` CRL extension (RFC 5280 §5.2.1) is constructed manually
+using a low-level SHA-1 hash of the issuer's SPKI DER via `openssl::sha::Sha1`
+(C interface, bypasses the FIPS provider check). This approach is intentional:
+the AKI is a key identifier, not a cryptographic commitment; RFC 5280 §4.2.1.1 explicitly
+permits SHA-1 for this use; and the FIPS provider's prohibition covers digest *algorithms
+in security services* (e.g. signatures), not identifier derivation. The CRL signature itself
+uses only FIPS-approved algorithms.
+
+### Database persistence (`crls` table)
+
+A new `crls` table stores `(issuer_id, crl_der, crl_number, generated_at, next_update)`.
+This enables cold-start recovery: on the first request to the public CDP after a restart,
+the server loads the last persisted CRL from DB into the in-memory cache. The DB write in
+`generate_crl` is best-effort — a DB failure is logged as `WARN` and does not fail the
+authenticated CRL generation request.
+
+## Consequences
+
+### Positive
+
+- **POS-001**: Full RFC 5280 §5 CRL distribution chain from issuance to revocation to
+  relying-party validation, without requiring any external OCSP infrastructure.
+- **POS-002**: Unauthenticated CDP endpoint aligns with RFC 5280 §3 requirements; no
+  credential leakage risk since it serves pre-signed, immutable DER bytes.
+- **POS-003**: CRL Number monotonicity guaranteed across restarts via unix-timestamp seed;
+  no DB round-trip required for counter state.
+- **POS-004**: Operator configuration is minimal — setting `kms_public_url` is sufficient
+  to activate end-to-end CDP injection; no per-CA configuration needed.
+- **POS-005**: FIPS compliance maintained for AKI construction (SHA-1 via C bypass) without
+  compromising the overall FIPS posture.
+- **POS-006**: DB persistence ensures the public CDP endpoint survives server restarts
+  without requiring a warm-up call.
+- **POS-007**: Crypto Officer gating on `generate_crl` (when COs are configured) is
+  consistent with the existing access-control model for privileged listing operations.
+
+### Negative
+
+- **NEG-001**: The public CDP endpoint serves *stale* CRLs between `generate-crl` calls.
+  Relying parties may not see a revocation until the CA owner regenerates the CRL. This
+  is the standard CRL trade-off (vs. OCSP stapling); operators must configure appropriate
+  `validity_days` and/or automate CRL regeneration on revocation events.
+- **NEG-002**: The in-memory cache is per-process. Multi-instance deployments behind a
+  load balancer will have independent caches; only the instance that handled the last
+  `generate-crl` request has the fresh CRL in RAM (all instances share the DB-persisted
+  copy after a DB write succeeds).
+- **NEG-003**: The `crls` table introduces a new DB schema dependency. Existing deployments
+  require a schema migration before upgrading.
+- **NEG-004**: CRL generation requires the issuer's private key to be accessible in the KMS
+  key store at request time. HSM-backed keys add latency on each `generate-crl` call.
+
+## Alternatives Considered
+
+### OCSP (Online Certificate Status Protocol, RFC 6960)
+
+- **ALT-001 Description**: Deploy an embedded OCSP responder alongside the KMS. Relying
+  parties query per-certificate status in real time.
+- **ALT-002 Rejection Reason**: OCSP requires per-request signing with a short-lived OCSP
+  signing certificate, nonce handling, and significant additional protocol surface area.
+  CRL is the simpler baseline required by most enterprise PKI stacks and is a prerequisite
+  before OCSP can be considered. OCSP stapling can be added as a future enhancement.
+
+### Auto-regenerate CRL on every Revoke call
+
+- **ALT-003 Description**: Trigger `generate_crl` automatically every time a `Revoke`
+  operation completes, keeping the public CDP always current.
+- **ALT-004 Rejection Reason**: Revoke is a hot path; signing a CRL requires private key
+  access (potentially HSM) and a DB round-trip. Coupling this to every revocation would add
+  latency and increase HSM wear. The current design keeps CRL generation an explicit,
+  operator-controlled operation. Automatic refresh can be added as an optional feature flag
+  in a future ADR.
+
+### Store CRL in object store / S3
+
+- **ALT-005 Description**: Push signed CRL bytes to an object store (S3, GCS) and serve
+  from there, decoupling CRL distribution from the KMS process.
+- **ALT-006 Rejection Reason**: Introduces an external dependency and complicates
+  deployment. The KMS already owns a database with reliable persistence; the `crls` table
+  is the simplest consistent extension of existing infrastructure.
+
+### External CRL signer (offline CA)
+
+- **ALT-007 Description**: Keep the signing CA key offline; export a signing request to an
+  offline process.
+- **ALT-008 Rejection Reason**: Out of scope for the KMS, which is designed to be the
+  online CA. Offline CA workflows require a separate product and are not addressed by this
+  ADR.
+
+## Implementation Notes
+
+- **IMP-001**: `GENERATED_CRL_CACHE` is a `LazyLock>>`.
+  The `RwLock` is async-aware to avoid blocking the Actix-web thread pool on cache reads
+  (which are the hot path for the public endpoint).
+- **IMP-002**: `CRL_SEQUENCE_COUNTER` is a `LazyLock` seeded from
+  `OffsetDateTime::now_utc().unix_timestamp()`. In the unlikely event of two processes
+  starting within the same second and both serving the public endpoint, a counter collision
+  is possible. Operators running active-active HA must use a shared sequence source (DB
+  sequence) or accept a one-second collision window; this is noted as a known limitation.
+- **IMP-003**: The `build_crl` function in `crate/crypto/src/openssl/crl.rs` encapsulates
+  all OpenSSL CRL construction. It is covered by FIPS-mode integration tests.
+- **IMP-004**: All new DB operations (`get_crl`, `upsert_crl`) implement both the SQLite
+  and PostgreSQL backends and are covered by the standard multi-backend test matrix.
+- **IMP-005**: The `encode_der_length` helper in `build_certificate.rs` now returns
+  `KResult<()>` to prevent silent truncation of CDP URIs longer than 65535 bytes.
+- **IMP-006**: Success criterion — `test_crl_validation_lifecycle` end-to-end test passes
+  on all DB backends (SQLite, PostgreSQL) in both FIPS and non-FIPS modes.

 ### `cosmian_kms_server_database`
 

From 9a16ef271cea05a95e3ebfb1c8af8af4c5fb6070 Mon Sep 17 00:00:00 2001
From: Manuthor 
Date: Thu, 20 Aug 2026 09:10:00 +0200
Subject: [PATCH 060/181] fix: follow RFC 5280 for RemoveFromCRL reason mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RFC 5280 §5.3.1 explicitly restricts removeFromCRL (reason code 8) to
delta CRLs only.  The KMS generates only complete CRLs; emitting reason
code 8 in a complete CRL violates the standard.

Fix: map RemoveFromCRL to Unspecified so the reasonCode extension is
omitted from CRL entries per RFC 5280 §5.3.1 (prefer absent over
unspecified(0)).

Also:
- Fix test_toml: add the 3 new CRL params to the expected TOML string
- Remove competitor mention from CRL validity doc comment
- Fix clippy: replace const-after-statement + indexing-slicing in
  test_crl_remove_from_crl_omits_reason_code

Subject: [PATCH 061/181] test(crl): verify CRL generation when CO role is
 disabled

Adds test_crl_without_co_full_lifecycle:
- Uses the plain default server (no crypto_officer_users configured)
- Owner creates a CA, issues 3 leaf certs, revokes all 3
- Asserts auto-regen on revoke fires (falls back to default_username)
- Asserts authenticated GET /certificates/{id}/crl returns 3 entries
- Asserts unauthenticated GET /public/certificates/{id}/crl returns 200
  with 3 entries and a Cache-Control header

This proves the single-admin fallback path in generate_crl() works
correctly when no CO is configured.

Subject: [PATCH 062/181] fix(ui): use public CRL endpoint to include certs
 from all users
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The authenticated GET /certificates/{id}/crl endpoint:
- Requires Crypto Officer role when crypto_officer_users is configured
- Would fail with 401 for non-CO users in multi-user deployments

The public GET /public/certificates/{id}/crl endpoint:
- Requires no authentication
- Serves the auto-generated CRL (kept fresh by the revocation trigger
  and the background refresh scheduler)
- The CRL was built with find_all() so it includes every revoked
  certificate issued by this CA regardless of ownership

UI changes:
- CertificateGenerateCrl.tsx: switch to /public/certificates/{id}/crl
- Remove validity_days field (not used by the public endpoint)
- Add informational Alert explaining auto-regen behaviour
- DER→PEM conversion done client-side (public endpoint returns DER)
- Better 404 error message guiding the user to revoke a cert first
- Rename 'Generate CRL' → 'Download CRL' in menu and UI

Server change:
- Update the 404 message on the public endpoint to mention auto-regen
  instead of sending users back to the authenticated endpoint

Subject: [PATCH 076/181] fix(test): update test_toml expected string for
 CrlConfig TOML section

After the CrlConfig refactoring (commit a984a67a) the three crl_* fields
are now a nested struct. toml::to_string() therefore serialises them as a
[crl] section at the end of the TOML output instead of flat top-level keys.

Update the hardcoded expected string in test_toml to match:
  - remove crl_default_validity_days/crl_refresh_check_hours/
    crl_refresh_overlap_hours from the flat top-level section
  - add [crl] section at the end (after [vault])

Fixes CI failure: tests::test_toml on non-fips Windows job 97186811284.

+# Revocation & CRL Distribution
+
+Certificate revocation in the Eviden KMS follows the two-phase model defined by
+[RFC 5280](https://www.rfc-editor.org/rfc/rfc5280):
+
+1. **Revoke** a certificate — the KMIP `Revoke` operation marks the certificate
+   `Deactivated` or `Compromised` in the KMS database.
+2. **Publish** the revocation — the `Generate-CRL` operation (or automatic
+   post-revocation refresh) signs a fresh CRL that relying parties can fetch.
+
+## CRL generation
+
+The KMS generates X.509 v2 Certificate Revocation Lists (CRLs) per
+[RFC 5280 §5](https://www.rfc-editor.org/rfc/rfc5280#section-5).
+
+A CRL lists all certificates issued by a CA that have been revoked. The KMS
+automatically collects **all** revoked certificates — those in `Deactivated` or
+`Compromised` state with a `CertificateLink` pointing to the issuer — regardless
+of which user owns each certificate record in the KMS database, then signs the
+CRL with the CA private key.
+
+**CLI usage:**
+
+```bash
+ckms certificates generate-crl \
+  --certificate-id  \
+  --validity-days 7 \
+  --output-format pem \
+  --output-file /tmp/crl.pem
+```
+
+**REST endpoint (authenticated):**
+
+```http
+GET /certificates/{issuer_id}/crl?format=pem&validity_days=7
+```
+
+Returns `application/pkix-crl` (DER, default) or `application/x-pem-file` (PEM).
+
+!!! note "Access control"
+    Any **authenticated** user with `Get` access to the CA certificate may call
+    this endpoint — no Crypto Officer role is required. CRL content is public
+    information (RFC 5280 §3); the authentication check exists to prevent the CA
+    private key from being used as an unauthenticated signing oracle, not to
+    restrict access to the revocation list itself.
+
+The generated CRL includes:
+
+- **Authority Key Identifier** (AKI) — derived from the CA's `subjectKeyIdentifier`
+  extension if present, or from a SHA-1 hash of the CA's `SubjectPublicKeyInfo` DER.
+- **CRL Number** — monotonically increasing integer, seeded at startup from
+  `max(unix_timestamp, db_max_crl_number + 1)` to guarantee strict monotonicity
+  across server restarts (RFC 5280 §5.2.3).
+- Per-entry **CRL Reason Code** — mapped from the KMIP revocation reason stored at
+  revocation time (RFC 5280 §5.3.1).
+- Per-entry **Invalidity Date** — `GeneralizedTime`-encoded date of compromise when
+  available in object attributes (RFC 5280 §5.3.2).
+
+### Configuration
+
+```toml
+# kms.toml
+[crl]
+crl_default_validity_days = 7   # default CRL validity in days (1–365)
+crl_refresh_check_hours   = 1   # background refresh check interval; 0 = disabled
+crl_refresh_overlap_hours = 24  # pre-regenerate this many hours before expiry
+```
+
+All three keys may also be set as CLI flags or environment variables:
+
+```bash
+--crl-default-validity-days 7
+--crl-refresh-check-hours   1
+--crl-refresh-overlap-hours 24
+```
+
+## Automatic CRL regeneration on revocation
+
+When `kms_public_url` is set in `kms.toml`, the server **automatically regenerates**
+the issuer's CRL in the background whenever a certificate is revoked via the
+`Revoke` operation. The regeneration is fire-and-forget: it does not block the
+`Revoke` response, and any signing failure is logged at `WARN` level without
+affecting the revocation outcome.
+
+```toml
+# kms.toml — enables CDP auto-injection and auto-CRL regeneration
+kms_public_url = "https://kms.example.com"
+```
+
+The updated CRL is immediately available at the public CDP endpoint:
+
+```http
+GET /public/certificates/{issuer_id}/crl    # no authentication required
+```
+
+## Scheduled CRL refresh
+
+A background scheduler wakes every `crl_refresh_check_hours` (default: 1 h) and
+regenerates any stored CRL whose `nextUpdate` timestamp falls within
+`crl_refresh_overlap_hours` (default: 24 h) of the current time. This prevents
+relying parties from seeing an expired CRL during the window between the scheduled
+expiry and the next revocation-triggered regeneration.
+
+Set `crl_refresh_check_hours = 0` to disable the background scheduler entirely
+(CRLs will only be refreshed on explicit `generate-crl` calls or `Revoke` events).
+
+## CRL distribution points
+
+When `kms_public_url` is configured, the KMS **automatically injects** a
+`crlDistributionPoints` (CDP) extension into every CA-issued certificate, pointing
+to the server's own public CRL endpoint:
+
+```text
+https:///public/certificates//crl
+```
+
+You do **not** need to supply a CDP extension manually for KMS-issued certificates
+when `kms_public_url` is set.

+## Public (unauthenticated) CRL endpoint
+
+`GET /public/certificates/{issuer_id}/crl` is intended for CRL Distribution Point
+(CDP) URIs embedded in certificates. Any relying party — browser, TLS stack, OCSP
+client — can fetch the current CRL without credentials, as required by
+[RFC 5280 §3](https://www.rfc-editor.org/rfc/rfc5280#section-3).
+
+The response includes:
+
+- `Content-Type: application/pkix-crl`
+- `Last-Modified` (RFC 7231 IMF-fixdate)
+- `Cache-Control: public, max-age=N` where N is derived from `nextUpdate − 60 s`
+
+The endpoint returns **404** only if the CRL has never been generated and no CRL
+is stored in the database.
+
+!!! note "Cold-start behaviour"
+    Generated CRLs are persisted in the KMS database (`crls` table) and reloaded
+    on server restart, so the public endpoint continues to serve the last signed CRL
+    without requiring a manual `generate-crl` call after each restart.
+
+## Authority Information Access (AIA)
+
+The AIA extension (`authorityInfoAccess`, OID `1.3.6.1.5.5.7.1.1`) can be added
+via the extension config file to point relying parties to an OCSP responder or to
+the CA issuer certificate:
+
+```ini
+[ v3_ext ]
+authorityInfoAccess=OCSP;URI:http://ocsp.example.com/,caIssuers;URI:http://ca.example.com/ca.crt
+```
+
+!!! note "OCSP responder not built in"
+    The KMS does not embed an OCSP responder. The AIA extension can reference an
+    external OCSP service. CRL-based revocation is fully supported; OCSP is a
+    future enhancement.
+
+## No Revocation Available (`id-ce-noRevAvail`, RFC 9608)
+
+For **self-signed certificates** (no issuer key provided) that do not carry a CRL
+distribution point, the KMS automatically adds the `id-ce-noRevAvail` extension
+(OID `2.5.29.56`, RFC 9608 §2). This signals to relying parties that no
+revocation information is available for this certificate, and that they MUST NOT
+reject it for lack of a CRL or OCSP response.
+
+This behaviour applies to **all algorithms** (RSA, EC, ML-DSA, SLH-DSA, …).
+
+When validating a chain, the KMS skips CRL fetching for any certificate that
+carries this extension.

-## Revocation handling
-
-### CRL generation
-
-The KMS can generate X.509 v2 Certificate Revocation Lists (CRLs) per
-[RFC 5280 §5](https://www.rfc-editor.org/rfc/rfc5280#section-5).
-
-A CRL lists all certificates issued by a CA that have been revoked. The KMS
-automatically collects **all** revoked certificates (those in `Deactivated` or
-`Compromised` state with a `CertificateLink` pointing to the issuer) regardless
-of which user owns each certificate in the KMS database, then signs the CRL with
-the CA private key.
-
-**CLI usage:**
-
-```bash
-ckms certificates generate-crl \
-  --certificate-id  \
-  --validity-days 7 \
-  --output-format pem \
-  --output-file /tmp/crl.pem
-```
-
-**REST endpoint (authenticated):**
-
-```http
-GET /certificates/{issuer_id}/crl?format=pem&validity_days=7
-```
-
-Returns `application/pkix-crl` (DER, default) or `application/x-pem-file` (PEM).
-
-!!! note "Crypto Officer required when CO is configured"
-    When `crypto_officer_users` is set in `kms.toml`, only an active Crypto Officer
-    may call this endpoint.  CRL generation uses a database-wide scan (`find_all`)
-    to return certificates from all users — the CO role is the gating condition for
-    that bypass, consistent with the CO-scoped `Locate` operation.
-    When no CO is configured (single-admin deployment), any user who owns the CA
-    certificate may generate its CRL.
-
-The generated CRL includes:
-
-- **Authority Key Identifier** (AKI) extension
-- **CRL Number** extension (monotonically increasing, seeded from unix timestamp to survive restarts)
-- Per-entry **CRL Reason Code** (mapped from the KMIP revocation reason stored at revocation time)
-- Per-entry **Invalidity Date** (when available in object attributes)
-
-### Automatic CRL regeneration on revocation
-
-When `kms_public_url` is set in `kms.toml`, the server **automatically regenerates**
-the issuer's CRL whenever a certificate is revoked via the `Revoke` operation.
-
-```toml
-# kms.toml — enables CDP auto-injection and auto-CRL regeneration
-kms_public_url = "https://kms.example.com"
-```
-
-The regeneration runs inline before the `Revoke` response is returned, using the
-first active Crypto Officer identity (or `default_username` in no-CO deployments).
-The updated CRL is immediately available at the public CDP endpoint:
-
-```http
-GET /public/certificates/{issuer_id}/crl    # no authentication required
-```
-
-If no active CO is found when one is required, the regeneration is skipped and a
-`warn`-level log is emitted — the CRL will be refreshed on the next manual
-`generate-crl` call or after a CO ceremony completes.
-
-### CRL distribution points
-
-When `kms_public_url` is configured, the KMS **automatically injects** a
-`crlDistributionPoints` (CDP) extension into every CA-issued certificate, pointing
-to the server's own public CRL endpoint:
-
-```text
-https:///public/certificates//crl
-```
-
-You do **not** need to supply a CDP extension manually for KMS-issued certificates
-when `kms_public_url` is set.
-
-To override or set a custom CDP manually (e.g. for an external CA), add a
-`crlDistributionPoints` entry in the extension config file passed via
-`--certificate-extensions`:
-
-```ini
-[ v3_ext ]
-crlDistributionPoints=URI:http://ca.example.com/crl.pem
-```
-

-The endpoint `GET /public/certificates/{issuer_id}/crl` is intended for CRL
-Distribution Point (CDP) URIs embedded in certificates. Any relying party —
-browser, TLS stack, OCSP client — can fetch the current CRL without credentials,
-as required by [RFC 5280 §3](https://www.rfc-editor.org/rfc/rfc5280#section-3).
-
-The response includes a `Last-Modified` header for HTTP caching (RFC 7232).
-The endpoint returns **404** only if the CRL has never been generated since the
-last server start **and** no CRL is stored in the database.
-
-!!! note "Cold-start behavior"
-    Generated CRLs are persisted in the KMS database (`crls` table) and reloaded
-    on server restart, so the public endpoint continues to serve the last signed CRL
-    without requiring a manual `generate-crl` call after each restart.

 test_data feature/split_key layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The test_data submodule (feature/split_key branch) reorganized
configs/server/ into subdirectories:
- crypto_officer_users.toml  → rbac/
- non_revocable.toml         → test/
- hsm.toml                   → hsm/hsm_test.toml
- pqc_tls.toml               → tls/

Update all four path references in test_server.rs accordingly.
Fixes all non-fips CI failures.

 - `AlwaysSensitive` is now server-managed: clients can no longer add/set/modify/delete it via `AddAttribute`, `SetAttribute`, `ModifyAttribute`, or `DeleteAttribute` — such requests are rejected with `Attribute_Read_Only` ([#1103](https://github.com/Cosmian/kms/pull/1103))
 - Read-only KMIP attributes could be rewritten by any client via `ModifyAttribute` (e.g. `Initial Date`, `Cryptographic Length`, `Unique Identifier`). All attributes marked "Modifiable by client: No" are now rejected with `Attribute_Read_Only`; "Deletable by client: No" attributes are rejected by `DeleteAttribute` ([#1103](https://github.com/Cosmian/kms/pull/1103))

 # CHANGELOG — feat/split_key
 
-## Features
-
-### Two-role RBAC (CryptoOfficer / Operator)
-
-Replaces the former `privileged_users` flat list with two FIPS 140-3 aligned roles:
-
-- **`Operator`** (default) — crypto-use ops: Encrypt, Decrypt, Sign, Verify, MAC, Hash, Locate, GetAttributes.
-- **`CryptoOfficer`** — key-lifecycle ops + ownership bypass: Create, Import, Certify, Rekey, Activate, Revoke, Destroy, Get, Export, SetAttribute, …
-- Unknown users default to `Operator` (fail-secure, NIST SP 800-57 Pt 2 §4.8).
-- New `[roles]` TOML section; migration: rename `privileged_users` → `crypto_officer_users` under `[roles]`.
-
-### Split-key ceremony (XOR n-of-n)
-
-`CreateSplitKey` and `JoinSplitKey` KMIP 2.1 (and 1.4) operations implement XOR n-of-n secret sharing:
-
-- Shares tagged `x-cosmian-crypto-officer-ceremony`; each owned by a different CO candidate.
-- `JoinSplitKey` with all ceremony shares auto-activates the CO role (writes `crypto_officer_activations`).
-- Activation records AES-256-GCM sealed from `ceremony_secret` (hex 32-byte); `ceremony_secret` masked in logs.
-- **Optional AES-KW share wrapping** (`ceremony_wrapping_key_id` / `KMS_CEREMONY_WRAP_KEY_ID`): each share encrypted with RFC 5649 before DB write; unwrapped transparently on `JoinSplitKey`. HSM-backed key supported.
-- `ceremony_key_id` (`KMS_CEREMONY_KEY_ID`) accepted by config parser for future KMS-object sealing key (ADP-26, not yet functional — use `ceremony_secret` in the meantime).
-
-### Revocation
-
-- **Self-revoke**: active CO calls `POST /access/crypto_officer/disable`.
-- **Peer revocation**: any CO candidate calls the same endpoint with `{ "target_user": "" }` to demote another active CO without server restart (NIST SP 800-152 FR:6.119).
-
-- **`CreateSplitKey` fix**: `ObjectType: SymmetricKey` added as first field in the TTLV request (the field is required/non-`Option` in the server struct); both `SplitKey.tsx` and `CryptoOfficerRole.tsx` previously omitted it, causing a 422 on every submission. Both callers now share a single `buildCreateSplitKeyRequest` helper from `utils/splitKeyUtils.ts`.
-- **Compensating delete**: if step 2 (`CreateSplitKey`) fails after step 1 (AES key creation) succeeds, the newly-created key is destroyed before the error is surfaced; this prevents permanent "object already exists" retry failure.
-- **Peer-revocation selector**: the logged-in user is now filtered out of the peer-revocation `Select`; self-revoke remains available via the empty selection.
-- **External CDN fonts removed**: `@font-face` declarations referencing `fonts.gstatic.com` (Inter URL was 404; Montserrat URL was live but violates air-gapped deployment requirements); falls back to system font stack.
-
-## Security
-
-- Zeroized key material throughout (`Zeroizing>`, `Drop` on `CeremonyKeys`).
-- **Compensating delete on activation failure**: reconstructed key deleted from DB if auto-activation fails; CRITICAL audit entry if the delete itself fails (prevents bypass via failed ceremony).
-- Audit events for `CreateSplitKey`/`JoinSplitKey` elevated to `error!(target="audit")` (CWE-778 mitigation).
-- Per-call session UUID stamped on all ceremony audit entries for SIEM correlation.
-- DB partial unique index on `activated_by WHERE revoked_at IS NULL` (PostgreSQL/SQLite); application-level guard on MySQL.
-- Complete `key_part_identifier` validation: shares must form `{1..=N}` with no duplicates.
-- Ceremony candidates exempted from `Create`/`Import` restriction before ceremony completes (prevents bootstrap deadlock).
-
-## CLI
-
-- `ckms access-rights crypto-officer status` — show role config and ceremony state.
-- `ckms access-rights crypto-officer disable` — revoke active ceremony.
-- New `create-split-key` subcommand under the `crypto-officer` CLI group.
+## Features — Key Ceremony (XOR n-of-n split knowledge)
+
+- **Split-key ceremony for Crypto Officer role** (NIST SP 800-57 Part 2 Rev 1 §4.6 split knowledge):
+  `CreateSplitKey` and `JoinSplitKey` KMIP 2.1 operations implement XOR-based secret sharing.
+  All $n$ shares are required to reconstruct; threshold always equals total parts (n-of-n scheme).
+- **Config-driven ceremony**: `[roles]` section gains `crypto_officer_require_ceremony`, `ceremony_secret`
+  (hex-encoded 32-byte AES-256 key for GCM sealing), `crypto_officer_users`. When enabled, ceremony
+  candidates are inactive until all shares are joined via `JoinSplitKey`.
+- **Automatic share tagging**: shares created by ceremony candidates carry `x-cosmian-crypto-officer-ceremony`
+  vendor attribute tag for automatic ceremony detection.
+- **Active record management**: `crypto_officer_activations` table persists ceremony records with
+  sealed payload (AES-256-GCM via KDF-derived keys), activated\_by/participants/key\_hash tracking,
+  revoke support with `revoked_at`/`revoked_by`.
+
+## Security Improvements
+
+- **Zeroization of key material**: `xor_split` / `xor_join` now use `Zeroizing>` throughout;
+  heap memory wiped on drop. Shares consumed via `into_iter()` (no clone), leaving a single
+  zeroized copy. Derived `CeremonyKeys.obfuscation_key` zeroed on drop via explicit `Drop` impl.
+- **`ceremony_secret` never logged**: custom `Debug` impl for `RolesConfig` masks `ceremony_secret`
+  as `""`; prevents secret exposure when `RUST_LOG=debug`.
+- **Strict permission enforcement on JoinSplitKey**: ceremony activation error now propagated with `?`
+  (previously swallowed with `warn!`), preventing silent failures where the reconstructed key is stored
+  but the role never activates.
+- **Fail-secure unenrolled users**: when roles are configured, unknown users default to Operator
+  (minimum privilege) instead of unrestricted access (NIST SP 800-57 Part 2 Rev 1 §4.8).
+- **Prevent duplicate active ceremony records**: `activate_crypto_officer_ceremony` revokes prior active
+  records before insert; SELECT uses `ORDER BY activated_at DESC LIMIT 1` for deterministic retrieval.
+- **Complete `key_part_identifier` validation**: join verifies identifiers are unique and form `{1..=N}`,
+  preventing duplicate-share attacks that would produce garbage reconstructed keys.
+- **Explicit `UniqueIdentifier` handling**: `unwrap_or_default()` replaced with match on
+  `TextString` variant; non-text UIDs return clear `KmsError::InvalidRequest`.
+
+## Features — Role Model (Two-Role RBAC)
+
+- **Two-role model**: `Operator` (default, read/write crypto ops) and `CryptoOfficer`
+  (lifecycle + ownership bypass). Replaces earlier three-role design.
+- **CryptoOfficerConfig**: simplified from former multi-role structs; fields are
+  `users`, `require_ceremony`, `ceremony_secret` — no longer includes `total_parts` (removed as dead code).
+- **`UserId` type safety**: dedicated newtype wrapping `String` with `From<&str>`, `Deref`,
+  `PartialEq` for `&str`/`String`, plus `try_new()` rejecting empty strings. Serde derives added.
+- **`ObjectHandle<'a>` enum**: typed object ID classifier with `is_hsm()`, `hsm_parts()`, prefix matching
+  replacing the removed `has_prefix()` utility; used consistently across dispatch/permissions/HSM paths.
+
+## CLI (`ckms`)
+
+- `ckms access-rights crypto-officer status` — print CO role configuration and ceremony state
+  (`GET /access/crypto-officer/status`).
+- `ckms access-rights crypto-officer disable` — revoke active CO ceremony (requires active CO).
+- Docs updated in `documentation/docs/kms_clients/main_commands.md` (heading levels fixed, trailing
+  whitespace removed).
 
 ## Web UI
 
-- **Crypto Officer page**: status dashboard (ceremony state, active CO list, custodian count); configurable base key ID with live share-UID preview (`#1`, `#2`…); peer-revocation dropdown (visible to active CO only); ceremony activation form.
-- **SplitKey / JoinSplitKey dialogs**: Shamir option removed; only XOR n-of-n supported. "Total Parts" renamed to "Number of Shares". Threshold and method selectors removed.
-- **Dark theme**: aligned to mdBook Eviden palette (`#161923` bg, `#bcbdd0` text, `#282d3f` sidebar, orange `#f14611`). `colorPrimary` changed from `#9e6eff` (purple) to `#f14611` (Cosmian brand orange) for brand consistency. Light `colorPrimary` changed from `#e34319` to `#c73f1b` (≥4.5:1 on white, WCAG AA). `colorInfo` (links) raised to `#4fa8d8` (≥4.5:1 on `#161923`). `colorTextSecondary` pinned to `#9fa0b8` to prevent the dark algorithm deriving a low-contrast value (~2.84:1) on the elevated card surface.
-- **Sidebar background**: both light and dark modes now use the `--cosmian-sidebar-bg` CSS variable, eliminating the disparity between themes.
+- **Crypto Officer page** (`/ui/access-rights/crypto-officer`): status page showing role config,
+  ceremony activation state, CO user list, and Disable button (visible only when active ceremony exists;
+  requires active CO privileges). Menu label shortened from "Crypto Officer Role" to "Crypto Officer".
+- **Search Objects locate buttons across action forms**: key/object/certificate identifier inputs in
+  symmetric, RSA, EC, Covercrypt, MAC, PQC, FPE, certificate, attribute, object, and rotation-policy
+  dialogs now use the reusable `KeyIdInput` component so users can search and select existing objects
+  directly from the form, with object-type filtering where applicable.
+- **SplitKey / JoinSplitKey dialogs**: removed unsupported "Polynomial Sharing GF(2^8)" (Shamir) option;
+  now defaults to XOR method. **Threshold (k) input removed** and **method selector removed** —
+  only XOR n-of-n is supported. Renamed "Total Parts" to "Number of Shares". Updated descriptions
+  to clarify all shares are required.
+- **JoinSplitKey dialog**: method selector removed (XOR is the only option). Description updated
+  to clarify all shares are required for n-of-n reconstruction.
+
+## Bug Fixes
+
+- **Ceremony candidate exemption extended to Create/Import**: ceremony candidates (users in
+  `crypto_officer_users` with `require_ceremony = true`) can now create and import keys before
+  completing the ceremony. Previously only `CreateSplitKey`/`JoinSplitKey` were exempted, causing
+  a chicken-and-egg problem where candidates could not create the master key to split.
+  The exemption remains scoped to ceremony candidates only — full CO privileges (ownership bypass)
+  still require ceremony completion.
+- **Missing test data restored**: re-added deleted config files in `test_data/configs/server/client/`
+  (`auth_plain*.toml`, `jwt.toml`) required by integration tests (`test_kms_all_authentications`,
+  `test_vendor_id_in_vendor_attributes`).
+- **Lychee exclude patterns added**: example OAuth URLs in config templates excluded from link checking.
+  Non-routable IP `1.2.3.4` (used in forward proxy tests) excluded from link checking.
 
 ## Testing
 
-- 7 ceremony vector tests (2-of-2, 3-of-3 round-trips, failure scenarios, full activate→disable→deny lifecycle).
-- 11 RBAC CLI tests (`rbac_tests.rs`): CO/Operator permission matrix per ADR-2026-06-24.
-- 7 RBAC E2E tests (`rbac-flow.spec.ts`): UI smoke tests for split-key and CO pages.
+- **7 ceremony vector tests**: `create_split_key_xor` round-trip (2-of-2, 3-of-3), `join_split_key_*`
+  variants covering consistency checks, failure scenarios, and full lifecycle activate→disable→deny.
+- **11 RBAC CLI tests** (`rbac_tests.rs`): verify the two-role model per ADR-2026-06-24:
+  CO can create/export/destroy keys; CO **cannot** encrypt/decrypt (Operator-only); Operator can
+  encrypt/decrypt with grant; Operator cannot create/export/destroy keys; CO ownership bypass;
+  Operator needs explicit grant; grant/revoke access flow.
+- **7 RBAC E2E tests** (`rbac-flow.spec.ts`): SplitKey/JoinSplitKey UI loading, access control
+  page smoke tests, grant access flow via UI, Crypto Officer page accessibility.
+- Server config TOMLs: `cert_auth_crypto_officer.toml`, `cert_auth_crypto_officer_ceremony.toml`,
+  `cert_auth_operator_only.toml`, `rbac/*.{toml}` for role-separation tests.
+- Pre-commit hook fixes applied: shellcheck SC2329/SC2086/SC2119, Go tab→space normalization,
+  CRLF→LF line endings, Python quote style, trailing whitespace, trailing newlines.

 ### Split-key ceremony activation (optional)
 
 `CryptoOfficerConfig.require_ceremony = true` defers activation of the ownership bypass
-until a KMIP `JoinSplitKey` operation completes with all n shares tagged
-`x-cosmian-crypto-officer-ceremony`. This enforces dual control / split knowledge at
-the module boundary — a Cosmian-designed mechanism, not a NIST-mandated protocol
-(SP 800-57 Part 2 Rev 1 documents split knowledge as an organizational practice to
-record, not an implementation to prescribe).
-
-**`JoinSplitKey` IS the activation**: when all shares carry
-`x-cosmian-crypto-officer-ceremony`, the server writes the `crypto_officer_activations`
-record as a side-effect. The dedicated `POST /access/crypto_officer/ceremony/activate`
-endpoint is kept for CLI backward compatibility only; the Web UI uses `JoinSplitKey` as
-the single activation action.
-
-Share UIDs follow the convention `#` (e.g. `ceremony-key-2026#1`).
-On `JoinSplitKey` the reconstructed key UID is derived by stripping the `#N` suffix
-(ceremony path only; generic splits use a fresh UUID to avoid collisions).
+until a KMIP `JoinSplitKey` operation with at least `threshold` shares tagged
+`x-cosmian-crypto-officer-ceremony` completes. This implements NIST SP 800-57 Part 2
+Rev 1 §4.6 (dual control / split knowledge) directly within the module boundary without
+requiring external tooling.
 
 Ceremony activation records are AES-256-GCM encrypted with keys derived from
 `KMS_CEREMONY_SECRET`, preventing forgery via direct database writes.
-`crypto_officer_activations` is the **sole source of truth** for CO role status — the
-`x-cosmian-crypto-officer-ceremony` tag on KMS objects is used only as validation input,
-never for privilege checks (prevents privilege escalation via arbitrary tag-setting).

-### Revocation
-
-Any configured CO candidate may revoke the active CO's ceremony:
-
-- **Self-revoke**: active CO calls `POST /access/crypto_officer/disable` → 200 OK.
-- **Peer revocation**: any CO candidate (in `crypto_officer_users`) calls
-  `POST /access/crypto_officer/disable` → revokes the active CO's role immediately.

-  `crypto_officer_users`.
+- **IMP-003**: `kms.toml` gains a new `[roles]` section accepting `crypto_officer_users`

+  *Note: the planned multi-domain evolution (ADP-16, see Future Evolution below) will

+  ceremony-related configuration.*
+- **IMP-004**: Migration path: in every `kms.toml`, move `privileged_users = [...]` into

   role model: `crypto_officer_role_allowed_ops`, `operator_role_blocked_lifecycle`,
-  and related privilege-escalation vectors.
-- **IMP-006**: `crypto_officer_activations` table is the sole role store.
-  The `x-cosmian-crypto-officer-ceremony` tag on KMS objects is validation input only —
-  never consulted for privilege decisions — preventing privilege escalation via
-  arbitrary tag-setting on objects the attacker controls.
-- **IMP-007**: `CreateSplitKey` server-side auto-determines share count from
-  `crypto_officer_users.len()` when the source key carries the ceremony tag.
-  Each share owned by a different CO candidate (round-robin). UIDs: `#`.
-- **IMP-008**: `JoinSplitKey` with all ceremony-tagged shares auto-activates the CO role.
-  No separate activation call needed from the Web UI. The dedicated REST endpoint
-  `POST /access/crypto_officer/ceremony/activate` is kept for CLI backward compatibility.
-- **IMP-009**: Revocation via `POST /access/crypto_officer/disable` with optional JSON body
-  `{ "target_user": "" }`. Omitting `target_user` is self-revoke (active CO only);
-  supplying it is peer revocation (any CO candidate). The demoted CO's reconstructed key
-  is NOT revoked — only the `crypto_officer_activations` row is updated (NIST SP 800-152 FR:6.119).
-- **IMP-010**: Share UID naming: `#` (e.g. `my-ceremony-key#1`).
-  On `JoinSplitKey`, reconstructed key UID = base UID (ceremony path only).
-- **IMP-011**: Optional AES-KW share wrapping (`ceremony_wrapping_key_id`). When set,
-  `CreateSplitKey` encrypts each share with RFC 5649 before DB write; `JoinSplitKey`
-  detects `x-cosmian-share-wrapping-key` vendor attribute and unwraps transparently.
-  The wrapping key can be HSM-resident when the KMS is HSM-backed.

+| **ADP-16** | `[roles]` TOML section removed; CO candidates assigned per-domain in a DB table. Only `KMS_CEREMONY_SECRET` env var survives. IMP-003/IMP-004 migration instructions become a transitional step only. |

+| **ADP-25** | Server generates the 256-bit ceremony secret internally (random); the operator-supplied `ceremony_secret` TOML field is removed. |
+| **ADP-3/15** | CO candidates assigned per-domain; ceremony activates all CO candidates for that domain simultaneously (vs current per-user activation). |
 
 Until that ADR is merged, the `[roles]` TOML section and the `--crypto-officer-users`

+
+ISO 27034 defines Organisational Normative Frameworks (ONF) and Application Normative Frameworks (ANF) with four assurance levels (L1–L4).
+
+### 5.1 Assurance level mapping
+
+| Level | Requirement | KMS evidence |

+## 6. OSSTMM
+
+The Open Source Security Testing Methodology Manual (OSSTMM) defines five security channels: **Human, Physical, Wireless, Telecommunications, Data Networks**. The KMS is primarily a data-network application.
+
+### 6.1 Data Networks channel
+
+| OSSTMM section | Test area | Finding | Status |
+|----------------|-----------|---------|--------|
+| 5.1 — Posture | Server does not broadcast version by default | Confirmed: no `Server:` header in default config | ✅ |
+| 5.3 — Enumeration | KMIP endpoint returns 422 (not 404) for invalid bodies | `curl -X POST -d '{}' .../kmip/2_1` → 422 | ✅ |
+| 5.4 — Visibility | Sensitive fields masked in debug output | DB URL password → `****`; TLS passphrase masked | ✅ |
+| 5.6 — Access | CORS headers do not reflect attacker origin | CORS tests `cors_config.rs` (C1–C3) confirm | ✅ |
+| 5.7 — Trust | JWKS source must use HTTPS | `validate_jwks_uris_are_https()` enforced at startup | ✅ |

+
+### 6.2 Residual risk summary
+
+| Risk area | Residual risk | Mitigation |
+|-----------|--------------|------------|
+| MFA enforcement | Low–Medium | Depends on OIDC provider configuration |
+| SQLite backup integrity | Low | WAL mode; deployment guide recommends periodic backups |
+| Rate limiting | Low | Not implemented at KMS level; recommend reverse-proxy (nginx, Caddy) |
+| Side-channel attacks | Very low | FIPS provider; constant-time primitives via OpenSSL |

 # Role Management and Key Ceremony
 
-Cosmian KMS supports two built-in roles, **Operator** and **CryptoOfficer**, so that
-day-to-day cryptographic use (encrypt, sign, decrypt) can be kept separate from
-key-lifecycle administration (create, activate, destroy, cross-user access). For
-deployments that want extra assurance around who can become a CryptoOfficer, the role
-can optionally require a **split-key ceremony**: instead of one person activating the
-role alone, the key that grants it is split across several people, and all of them must
-cooperate to activate it.
+Cosmian KMS implements a two-role **Role-Based Access Control** (RBAC) model drawing on
+two normative sources:
+
+- **[ISO/IEC 19790:2012](https://csrc.nist.gov/pubs/fips/140-3/final)** (adopted by [FIPS 140-3](https://csrc.nist.gov/pubs/fips/140-3/final)) —
+  defines mandatory Crypto Officer and User roles for cryptographic modules.
+- **[NIST SP 800-57 Part 2 Rev 1](https://csrc.nist.gov/pubs/sp/800/57/pt2/r1/final)** —
+  prescribes split knowledge and dual control for key management.
+
+The **CryptoOfficer** role can optionally require a *split-key ceremony* for activation
+under the principle of *split knowledge*
+([NIST SP 800-57 Part 2 Rev 1 §4.6](https://csrc.nist.gov/pubs/sp/800/57/pt2/r1/final)).
+Without a ceremony, users in the `crypto_officer_users` list are immediately active.
+With a ceremony, the role is **dormant** until a quorum of custodians assembles
+all key shares — making a single compromised account insufficient to
+gain the privileged role.

+## Normative foundations
+
+### XOR-based split knowledge
+
+The ceremony relies on **$n$-of-$n$ split knowledge**: the master key is split into $n$
+shares using XOR, and *all* $n$ shares are required to reconstruct the secret.
+The scheme is information-theoretically secure: any strict subset of shares reveals zero
+information about the master key.
+
+1. A dealer generates $n-1$ uniformly random byte strings, each of the same length $\ell$ as the secret $s$.
+2. The final share is the XOR of the secret with all other shares: $r_n = s \oplus r_1 \oplus \cdots \oplus r_{n-1}$.
+3. Reconstruction: $s = r_1 \oplus r_2 \oplus \cdots \oplus r_n$ — all shares are required.
+
+The constraint: $n \ge 3$ (threshold equals total parts, minimum 3 custodians required).
+
+!!! danger "Why n ≥ 3 is mandatory (not n ≥ 2)"
+    With only two custodians (Alice and Bob), the scheme provides no real dual control.
+    The dealer who creates the master key $K$ and retains share $S_1$ can trivially compute
+    Bob's share: $S_2 = K \oplus S_1$. This means Alice knows both shares from the moment of
+    creation — Bob's active cooperation is never required.
+
+    With **n ≥ 3** custodians, the dealer knows $K$ and one share $S_1$, but can only compute
+    $S_2 \oplus S_3 \oplus \cdots \oplus S_n$ — not any individual share. Genuine cooperation
+    from at least $n-1$ other custodians is always required.
+
+    This follows directly from the information-theoretic security of XOR splitting (see
+    [NIST SP 800-57 Part 2 Rev 1 §4.6](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-57pt2r1.pdf)).
+    **The KMS rejects ceremony configuration with fewer than 3 custodians at startup.**
+
+!!! warning "Ceremony key destroyed after split"
+    When a key is split for a ceremony (`x-cosmian-crypto-officer-ceremony` attribute),
+    the server **automatically destroys** the original key after all shares are stored.
+    This is a defense-in-depth measure: even if the dealer had exported the original key
+    before splitting, destroying it removes the direct reconstruction path and forces

 !!! note "Fail-secure default"
     When `crypto_officer_users` is configured but a user is not in the list, the server
     assigns the **Operator** role (minimum privilege). Users are never silently promoted.
 
-!!! warning "Ownership bypass excludes HSM-backed keys"
-    The CryptoOfficer ownership bypass applies to KMS-managed objects only. Keys stored
-    in an HSM are **not** covered: access to them stays governed by the HSM's own admin
-    rules, regardless of CryptoOfficer status.
+!!! info "ISO/IEC 19790 mapping"
+    ISO/IEC 19790:2012 §7.4 defines two mandatory roles: the Crypto Officer (key management
+    and module configuration) and the User (general cryptographic operations). The Cosmian KMS
+    `CryptoOfficer` corresponds to the Crypto Officer and the `Operator` corresponds to
+    the User. ISO/IEC 19790 requires each role's services to be clearly defined and enforced,
+    but does **not** prohibit the CO from also holding User services. NIST SP 800-57 Part 2
+    Rev 1 confirms that a CO "can perform encryption, decryption, and other operations to the
+    extent defined by policy." Cosmian KMS policy grants the CO the full superset.

-## Turning on CryptoOfficer
+## CryptoOfficer role
+
+The CryptoOfficer role enforces **key lifecycle management**, **key output**, **cryptographic use**,
+and **ownership bypass** as defined in
+[ISO/IEC 19790:2012 §7.4](https://csrc.nist.gov/pubs/fips/140-3/final) and
+[NIST SP 800-57 Part 2 Rev 1](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-57pt2r1.pdf).
+
+CryptoOfficers may:
+
+- Create, import, certify, activate, revoke, and destroy objects
+- Access raw key material (`Get`, `Export`) — "key output" per ISO/IEC 19790 §7.4
+- Manage object attributes
+- **Use keys cryptographically** (`Encrypt`, `Decrypt`, `Sign`, `SignatureVerify`, `MAC`, `Hash`, `Validate`)
+- **Access any object** regardless of ownership (bypass per-object permission checks)
+- **Locate all objects** (bypasses user filtering in `Locate`)
 
-There are two ways to grant the CryptoOfficer role, chosen per deployment.
+!!! note "Why COs can also encrypt/decrypt"
+    A dormant CO candidate is treated as an Operator and can already use keys cryptographically.
+    Removing those privileges upon CO activation would reduce permissions on promotion — contrary
+    to least-privilege semantics and operational necessity (a CO must be able to test keys they
+    manage). ISO/IEC 19790 §7.4 mandates that each role's services are *defined and enforced*;
+    it does not mandate mutual exclusion between the two role service sets.

-## Walkthrough: a 3-person ceremony
-
-The diagram below follows a ceremony with three custodians, Alice, Bob, and Carol,
-(which is also the minimum the KMS accepts).
-
-![Split-key ceremony overview](crypto_officer_ceremony.png)
+## Ceremony lifecycle
 
-Alice creates the master key and splits it into three shares; the KMS destroys the
-original immediately, so from that point on not even Alice can recover it alone. Bob and
-Carol each hold a share Alice does not have. To activate the CryptoOfficer role, Alice
-needs her own share plus at least one of theirs, which means Bob or Carol must actively
-grant her access first, so Alice cannot silently activate on her own.
+### Phase 1 — Provisioning
 
-!!! info "Why not just two people?"
-    With two custodians, whoever creates the key can always compute the other person's
-    share from the key and their own share, so no real cooperation is required. Three is
-    the minimum where that shortcut disappears, which is why the KMS rejects fewer than
-    3 custodians at startup.
+The CO candidate creates an AES key, splits it into $n$ shares, and distributes them
+to custodians. The number of shares is auto-determined by the server from the
+`crypto_officer_users` count, and each share is auto-assigned to a different CO
+candidate (dual-control enforcement).
 
-### Phase 1: Provisioning
-
-The number of shares is auto-determined from the `crypto_officer_users` count, and each
-share is auto-assigned to a different CO candidate. No server restart is needed: the
-ceremony candidate exemption lets a CO candidate call `Create`, `CreateSplitKey`, and
-`JoinSplitKey` even before the ceremony completes, which is what breaks the
-chicken-and-egg problem of needing the role to set up the role.
+No restart is required — the ceremony candidate exemption allows
+`Create`, `Import`, `CreateSplitKey`, and `JoinSplitKey` even before the ceremony
+completes, breaking the chicken-and-egg problem.

 ```
 
-### Phase 2: Activate Crypto Officer Role (JoinSplitKey)
+!!! note "Source key is destroyed"
+    The server destroys the ceremony source key immediately after all shares are stored,
+    as a defense-in-depth measure (see note in the XOR scheme section above).
+
+### Phase 2 — Activation ceremony
+
+**One candidate — one ceremony.** A single person in `crypto_officer_users` calls
+`POST /access/crypto_officer/ceremony/activate`. Only that person becomes an active
+CryptoOfficer; other users in the list remain Operators until they complete their own
+ceremony.
+
+The candidate assembles all $n$ custodians who each grant access to their share, then
+calls the ceremony activation endpoint with all share UIDs. The server:
+
+1. Retrieves each share — the candidate must have `Get` on each.
+2. Verifies all shares carry the `x-cosmian-crypto-officer-ceremony` attribute.
+3. Verifies all shares originate from the same source key.
+4. Verifies the share count equals the threshold.
+5. Verifies the candidate is in `crypto_officer_users`.
+6. Verifies the candidate does **not** own any of the shares (strict dual-control).
+7. Reconstructs the secret via XOR **in server RAM only** — never stored as a KMS object.
+8. Persists a `crypto_officer_activations` record (activated-by user, SHA-256 key
+   fingerprint, participant list, timestamp).
+9. Zeroizes the reconstructed secret (ADP-20).
+
+**The activation is bound to the activating user**: only the user named in
+`activated_by` of the sealed record is granted CryptoOfficer status.
+
+!!! info "Ceremony activation is separate from JoinSplitKey"
+    `JoinSplitKey` (KMIP operation) is a key reconstruction tool — it produces a usable
+    cryptographic object. The ceremony activation uses a dedicated REST endpoint
+    (`POST /access/crypto_officer/ceremony/activate`) that reconstructs the secret in
+    RAM and zeroizes it immediately, never creating a managed KMS object. This
+    separation implements ADP-20 and keeps key management operations distinct from
+    access-control operations.

-  the caller.
-- **`POST /access/crypto_officer/ceremony/activate`** (`ckms access-rights crypto-officer
-  activate`, or the Web UI's Crypto Officer Role page): reconstructs the secret in RAM

    • Verify count = n
    • Verify user ∈ crypto_officer_users

    • Zeroize secret (ADP-20)
+    KMS-->>CO: {success: "Crypto Officer ceremony activated..."}

-   ceremony tag, same source key, correct count, and the candidate listed in
-   `crypto_officer_users`.
-2. Checks that at least one share belongs to a **different** CO: the activating candidate
-   may own shares, but not all of them. This is what prevents solo self-activation.
+    Note over CO,KMS: CryptoOfficer role is now ACTIVE
+    CO->>KMS: GET /access/crypto_officer/status → {enabled: true, ceremony_activated: true}
+```
 
-Either way, the server persists the `crypto_officer_activations` record and the candidate
-is now an **active CryptoOfficer**.
+### Phase 3 — Active use
 
-!!! warning "Key storage difference between the two mechanisms"
-    `JoinSplitKey` stores the reconstructed key as a usable KMS object; `ceremony/activate`
-    does not — the secret is RAM-only and zeroized immediately after the activation record
-    is written. Pick based on whether you need the reconstructed key as a managed object
-    afterward.
+While the ceremony is active, the CryptoOfficer can manage all keys in the KMS:

-## Revoking
+### Phase 4 — Revocation
 
-Any configured CO candidate may revoke the active CO's ceremony:
+Any active CryptoOfficer can disable the ceremony (self-disable). The role becomes
+dormant until a new `JoinSplitKey` ceremony completes.

+

+|---|---|
+| **Information-theoretic secrecy** | $< n$ shares reveal zero bits about the secret |
+| **Single-point-of-failure elimination** | No single custodian can activate the role alone |
+| **Insider threat mitigation** | A user in `crypto_officer_users` cannot escalate without all custodians cooperating (n ≥ 3 prevents dealer computing other shares) |
+| **Dealer-colluder resistance** | With n ≥ 3, the key creator knows one share; deriving any other individual share is impossible without that custodian's cooperation |
+| **Audit trail** | Every activation records: activator, participant list, SHA-256 key fingerprint, timestamp |
+| **Self-revocability** | Any active CryptoOfficer can immediately revoke the ceremony |
+| **Dual-control enforcement** | Assembling user must not own any share — all shares must come from other CO candidates |
+| **Replay prevention** | Re-activation requires re-running the full ceremony activation endpoint |
+| **RAM-only reconstruction** | The ceremony secret is reconstructed in server process RAM only during `/ceremony/activate`; zeroized immediately after — never stored as a KMS object (ADP-20) |
+| **Ceremony key destruction** | The source key is automatically destroyed after all shares are stored, removing any direct reconstruction path |
+| **HSM key exclusion** | Ownership bypass does not apply to HSM-backed keys (governed by HSM admin rules) |

+    `ckms sym keys join-split-key` (KMIP `JoinSplitKey`) reconstructs a split key into
+    a usable managed KMS object — use it when you need the raw key material for
+    cryptographic operations. To activate the Crypto Officer ceremony role, use
+    `ckms access-rights crypto-officer activate` or the Web UI **Crypto Officer Role**
+    page instead.

-### Role store vs. key store
-
-**Important security boundary:**
-
-| Store                                 | Written by                                                                            | Purpose                                                                                                                                                                     |
-| ------------------------------------- | ------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `crypto_officer_activations` DB table | `JoinSplitKey` on ceremony shares, or `POST /access/crypto_officer/ceremony/activate` | **Sole source of truth** for CO role status. Sealed with AES-256-GCM under `ceremony_secret`.                                                                               |
-| `objects` DB table                    | Every `JoinSplitKey` call (ceremony and non-ceremony)                                 | Stores the reconstructed key as a managed KMS object owned by the caller. For ceremony shares the key is stored **unconditionally** before the activation side-effect runs. |
-
-!!! info "Two ceremony completion paths"
-    - **`JoinSplitKey` KMIP operation**: stores the reconstructed key in `objects` **and** writes the CO activation record. Suitable when you need the reconstructed key as a usable KMS object.
-    - **`POST /access/crypto_officer/ceremony/activate`**: reconstructs the secret in RAM only (for hash verification), writes the CO activation record, and **does not store a key object**.
-
-The `x-cosmian-crypto-officer-ceremony` tag on shares identifies which shares belong to
-a ceremony split. **It does NOT grant any privilege.** The server checks this tag only
-during ceremony activation validation, never for privilege checks. This prevents an
-attacker calling `Create(key)` + `SetAttribute(x-cosmian-crypto-officer-ceremony=true)`
-from escalating to CO role.

Subject: [PATCH 081/181] fix(clippy): fix unseparated literal suffixes and add
 test module allows

- Add #[allow(clippy::unwrap_used, clippy::expect_used,
  clippy::assertions_on_result_states)] to test modules in
  create_split_key.rs and join_split_key.rs, matching the pattern
  already used in key_ceremony_tests.rs
- Fix integer literal suffixes: 0xABu8 -> 0xAB_u8, etc.
- Fix doc_markdown: add backticks around create_split_key in module
  doc comment of key_ceremony_tests.rs

Also update test_ceremony_full_lifecycle_cli to reflect multi-CO
quorum guard: single CO cannot unilaterally disable ceremony.
Phase 4 now asserts disable is correctly rejected; phases 5-6
removed as they depended on Phase 4 succeeding.

Also sync log-reference.md with new log entries from this branch.

Subject: [PATCH 082/181] fix(co-ceremony): add target_user to disable endpoint
 for peer revocation

The POST /access/crypto_officer/disable endpoint previously only accepted
a self-revocation call (no body) and blocked multi-CO revocations via a
quorum guard. This contradicted the architecture where any CO candidate
can peer-revoke an active CO.

Changes:
- permissions.rs: disable_crypto_officer_ceremony(caller, target_user: Option)
  - Any configured CO candidate (in crypto_officer_users) may revoke
  - target_user=None -> self-revoke (caller must be active CO)
  - target_user=Some(victim) -> peer revocation (victim must be active CO)
  - Removed quorum guard that blocked multi-CO revocation
  - audit log records both revoked_by and revoked_user fields
- routes/access.rs: DisableCryptoOfficerRequest body with optional target_user
- key_ceremony_tests.rs:
  - TM-F006: rewritten as 'active CO self-revokes'
  - TM-F008: dormant CO peer-revokes active CO
  - TM-F009: reconstructed key intact after peer revocation
  - TM-F010: Operator cannot peer-revoke

 - **IMP-001**: `crate/access/src/access.rs` — new `Role` enum with two variants:
   `Operator` and `CryptoOfficer`. New `CryptoOfficerConfig` and `RolesConfig` structs
   replace the former flat `privileged_users` field in `ServerParams`.
-- **IMP-002**: `crate/server/src/config/command_line/roles_config.rs` — new CLI flags:
+- **IMP-002**: `crate/server/src/config/command_line/roles_config.rs` — CLI flags:
   `--crypto-officer-users`, `--crypto-officer-require-ceremony`,
-  `--crypto-officer-total-parts`, `--ceremony-secret` (env `KMS_CEREMONY_SECRET`).
+  `--ceremony-secret` (env `KMS_CEREMONY_SECRET`),
+  `--ceremony-key-id` (env `KMS_CEREMONY_KEY_ID`, ADP-26 scaffold).
   The former `--privileged-users` flag is removed.
-- **IMP-003**: `kms.toml` gains a new `[roles]` section accepting `crypto_officer_users`
-  and related ceremony fields. The top-level `privileged_users` key is removed; servers
-  with configs containing `privileged_users` will emit a parse error on startup.
-  *Note: the planned multi-domain evolution (ADP-16, see Future Evolution below) will
-  remove the `[roles]` TOML section entirely; `KMS_CEREMONY_SECRET` will be the only
-  ceremony-related configuration.*
-- **IMP-004**: Migration path: in every `kms.toml`, move `privileged_users = [...]` into
-  a `[roles]` section and rename the key to `crypto_officer_users`.
+- **IMP-003**: `kms.toml` `[roles]` section with `crypto_officer_users`,
+  `crypto_officer_require_ceremony`, `ceremony_secret`.
+- **IMP-004**: Migration: move `privileged_users = [...]` into `[roles]`, rename to
+  `crypto_officer_users`.
 - **IMP-005**: New FIPS test vectors in `test_data/vectors/access_control/` cover the
   role model: `crypto_officer_role_allowed_ops`, `operator_role_blocked_lifecycle`,
-  and related privilege-escalation vectors. These are registered in
-  `crate/test_kms_server/src/vector_runner.rs`.
-- **IMP-006**: Security property — during `JoinSplitKey` the server holds the
-  reconstructed ceremony secret momentarily in process RAM. The reconstructed key is
-  stored as a managed object; the activation record carries its SHA-256 fingerprint.
-  The planned multi-domain evolution (ADP-20) will zeroize the secret after
-  verification, so it is **never stored**.

+- **IMP-006**: `crypto_officer_activations` table is the sole role store.
+  The `x-cosmian-crypto-officer-ceremony` tag on KMS objects is validation input only —
+  never consulted for privilege decisions — preventing privilege escalation via
+  arbitrary tag-setting on objects the attacker controls.
+- **IMP-007**: `CreateSplitKey` server-side auto-determines share count from
+  `crypto_officer_users.len()` when the source key carries the ceremony tag.
+  Each share owned by a different CO candidate (round-robin). UIDs: `#`.
+- **IMP-008**: `JoinSplitKey` with all ceremony-tagged shares auto-activates the CO role.
+  No separate activation call needed from the Web UI. The dedicated REST endpoint
+  `POST /access/crypto_officer/ceremony/activate` is kept for CLI backward compatibility.
+- **IMP-009**: Revocation supports self-revoke (active CO) and peer revocation (any other
+  CO candidate). The demoted CO's reconstructed key is NOT revoked — only the
+  `crypto_officer_activations` row is updated. Peer revocation enables compromise
+  recovery without server restart (NIST SP 800-152 FR:6.119).
+- **IMP-010**: Share UID naming: `#` (e.g. `my-ceremony-key#1`).

 CLI flag described in IMP-002/IMP-003 remain the authoritative configuration surface.

Subject: [PATCH 083/181] feat(ui): brand theme + configurable split key ID +
 peer CO revocation UI

- Align Web UI dark theme to mdbook eviden.css tokens (orange #f97850, teal #82c0c7)
- Add Inter + Montserrat fonts and Cosmian CSS custom properties
- CO Role page: configurable ceremony key ID input with live #N share-UID preview
- CO Role page: peer revocation via Select dropdown (populated from CO candidates list)
- Status endpoint: expose users list to all CO candidates (not only active CO)
  so dormant COs can see peers and select them for revocation
- pre-commit: mark ui-test and ui-e2e stages as manual to avoid blocking commits

 ### Redis with Findex
 
-Redis-with-Findex provides application-level encryption over Redis, combining AES-256-GCM encrypted objects with
-encrypted Findex indexes. See the dedicated [Redis with Findex](./redis.md) page for a full description,
-encryption details, and configuration reference.
+**Redis with Findex** offers the ability to use Redis as a database with application-level encryption: all data is
+encrypted (using AES 256 GCM) by the KMS servers before being sent to
+Redis. [Findex](https://github.com/Cosmian/findex/) is an Eviden cryptographic algorithm used to build encrypted indexes
+on encrypted data, also stored in Redis. This allows the KMS to perform fast encrypted queries on encrypted data. Redis
+with Findex offers post-quantum resistance on encrypted data and encrypted indexes.
+
+**Redis-with-Findex** is most useful when:
+
+- KMS servers are run inside a confidential VM or an enclave. In this case, the secret used to encrypt the Redis data
+  and indexes, is protected by the VM or enclave and cannot be recovered at runtime by inspecting the KMS servers'
+  memory.
+- KMS servers are run by a trusted party but the Redis backend is managed by an untrusted third party.
+
+Redis-with-Findex is the database selected
+to [run the Eviden KMS in the cloud or any other zero-trust environment](../../installation/marketplace_guide.md).

-
-For the full database configuration reference, including TLS, clearing, and migration, see [Databases](./configuration.md).

-!!! note "Clearing the database"
-    When `clear_database` is set, the KMS issues a `FLUSHDB` to Redis on startup, deleting all keys in the selected Redis database.

Subject: [PATCH 084/181] feat(co-ceremony): add create-split-key subcommand to
 crypto-officer CLI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add `ckms access-rights crypto-officer create-split-key` command
  * Creates a fresh AES-256 key (optional --key-id for custom UID)
  * Stamps x-cosmian-crypto-officer-ceremony vendor attribute
  * Calls CreateSplitKey — server auto-assigns n=custodians_count shares
  * Each share owned by a different CO candidate (round-robin)
  * Validates ≥2 CO candidates configured before proceeding

- fix(split-key): ceremony mode activates when require_ceremony=true AND
  CO users are configured (global server enforcement), not only via key attribute

- fix(split-key): use owm.id() for share UID naming when caller passes a tag

- fix(clippy): Box::pin around ONCE.get_or_try_init in test_server.rs

- fix(co-ceremony): crypto_officer_disable() sends valid JSON body

- fix(lychee): exclude webstore.ansi.org (returns 403 to automated crawlers)

   to clarify all shares are required.
 - **JoinSplitKey dialog**: method selector removed (XOR is the only option). Description updated
   to clarify all shares are required for n-of-n reconstruction.
+- **Dark theme aligned with the documentation site**: the Web UI dark theme now reuses the same
+  mdBook "navy" palette as `docs.cosmian.com` (near-black `#161923` background, `#bcbdd0` text,
+  `#282d3f` sidebar) instead of the previous gray surfaces. The light theme uses the darker brand
+  orange `#c73f1b` for the primary accent. The sidebar menu and all surfaces now switch together
+  with the light/dark toggle.
+- **Contrast fixes (WCAG AA)**: resolved unreadable colour combinations in dark mode — dark text on
+  the black background (`text-gray-800`, `text-blue-800`, `text-red-800`), light-gray helper text on
+  white, near-invisible borders, and the low-contrast orange/teal accents — now meet AA contrast in
+  both themes.

 - **Crypto Officer page** (`/ui/access-rights/crypto-officer`): status page showing role config,
   ceremony activation state, CO user list, and Disable button (visible only when active ceremony exists;
   requires active CO privileges). Menu label shortened from "Crypto Officer Role" to "Crypto Officer".
+- **Crypto Officer page fully localized**: all labels, descriptions, badges, tooltips, and ceremony
+  workflow steps are now translated via i18n, including Chinese (`zh-CN`). The menu entry
+  "Crypto Officer" is also localized.
+- **Split Key and Join Split Key pages localized and kept generic**: both dialogs
+  (`/ui/sym/keys/split` and `/ui/sym/keys/join`) render their headings, descriptions, labels,
+  placeholders, validation messages, and result text via i18n (English and Chinese). They no longer
+  reference the key ceremony or Crypto Officer role — the share count is always user-editable. The
+  corresponding "Split"/"Join" menu entries are also localized.
 - **Search Objects locate buttons across action forms**: key/object/certificate identifier inputs in
   symmetric, RSA, EC, Covercrypt, MAC, PQC, FPE, certificate, attribute, object, and rotation-policy
   dialogs now use the reusable `KeyIdInput` component so users can search and select existing objects

Subject: [PATCH 086/181] fix(e2e): retry on transient 'Failed to fetch' in key
 creation helpers

submitWithFetchRetry() re-navigates and re-applies form setup on a
transient network error before surfacing a hard assertion failure.
createRsaKeyPair/createEcKeyPair/createPqcKeyPair all use it.

Also set retries:1 for both local and CI runs (was CI-only) so a
single transient flake does not fail a local run.

 - Resolve 8 Dependabot security alerts ([#1083](https://github.com/Cosmian/kms/pull/1083))
-- Upgrade `opentelemetry_sdk` 0.29.0 → 0.32.1 (SSRF via malicious OTLP endpoint, GHSA-r74r-p7x6-m97p) + React dependency updates ([#1073](https://github.com/Cosmian/kms/pull/1073))

 - `AlwaysSensitive` is now server-managed: clients can no longer add/set/modify/delete it via `AddAttribute`, `SetAttribute`, `ModifyAttribute`, or `DeleteAttribute` — such requests are rejected with `Attribute_Read_Only` ([#1103](https://github.com/Cosmian/kms/pull/1103))
 - Read-only KMIP attributes could be rewritten by any client via `ModifyAttribute` (e.g. `Initial Date`, `Cryptographic Length`, `Unique Identifier`). All attributes marked "Modifiable by client: No" are now rejected with `Attribute_Read_Only`; "Deletable by client: No" attributes are rejected by `DeleteAttribute` ([#1103](https://github.com/Cosmian/kms/pull/1103))

From 738dbac412dec7959b94c6a177832c66cc0cf8ca Mon Sep 17 00:00:00 2001
From: Manuthor 
Date: Mon, 17 Aug 2026 15:38:38 +0200
Subject: [PATCH 088/181] feat(kmip-1.4): implement CreateSplitKey and
 JoinSplitKey for KMIP 1.4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both operations are defined in KMIP 1.4 spec (§4.38 and §4.39) but were
missing correct struct definitions and 1.4↔2.1 conversion impls.

Changes:
- Fix CreateSplitKey 1.4 struct: add object_type (required), optional
  unique_identifier (key to split), rename parameter→prime_field_size
- Fix CreateSplitKeyResponse 1.4 struct: replace wrong split_key_parts
  field with spec-compliant split_key_unique_identifiers list
- Fix JoinSplitKey 1.4 struct: replace binary split_key_parts data
  with spec-compliant object_type + split_key_unique_identifiers list
- Add From (1.4→2.1): maps optional UID to empty
  TextString when absent (server generates a new key)
- Add TryFrom (2.1→1.4)
- Add From (1.4→2.1): split_key_method defaults to XOR
  (overridden by handler after reading the stored shares)
- Add TryFrom (2.1→1.4)
- Wire CreateSplitKey and JoinSplitKey into the Operation TryFrom
  conversions (both 1.4→2.1 and 2.1→1.4 directions)
- Add 4 new round-trip and conversion tests in kmip_1_4_tests.rs

All 214 kmip tests and 32 key ceremony tests pass.

Subject: [PATCH 089/181] fix(wizard): remove dead fields from AuthWizardResult
 and wire auth_verifier

http_api_token was always None (token written directly into HttpConfig).
ui_config_oidc was already applied inside configure_auth via ui.ui_oidc_auth.
auth_verifier was built but never wired into ClapConfig by the caller.

- Remove http_api_token and ui_config_oidc from AuthWizardResult
- Remove all #[allow(dead_code)] suppressions
- Wire auth_verifier: auth_result.auth_verifier into ClapConfig in mod.rs

Subject: [PATCH 090/181] fix(ui): gate CO revoke UI on is_crypto_officer +
 sync log-reference.md
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The disable-btn was rendered for any user when ceremony_activated && users.length > 0,
causing the unit test to fail:
  CryptoOfficerRevoke.test.ts:93 – non-active CO saw disable-btn (expected null)

Fix: condition changed to ceremony_activated && is_crypto_officer so only the
currently active CO sees the revoke section (self-revoke or peer-revoke via
the target selector). Dormant CO candidates can still call the backend API.

Also sync log-reference.md: one log message in kms_client changed wording.

Subject: [PATCH 091/181] docs(get-attrs): fix stale comment about SplitKey
 stored Attributes

The comment claimed crypto metadata (algorithm, length, format) is NOT
duplicated into the stored Attributes. This is wrong: create_split_key.rs
sets cryptographic_algorithm, cryptographic_length, and key_format_type in
share_attrs and passes them to database.create at creation time.

The overlay code in get.rs is a valid defensive fallback for:
- SplitKey objects imported via KMIP without explicit attributes
- Attributes cleared by DeleteAttribute
- Any pre-fix objects in existing databases

Updated the comment to accurately describe the fallback purpose.

-## 1. Scope & Methodology
-
-### 1.1 In-scope components
-
-| Component | Technology | Risk level |
-|-----------|-----------|------------|
-| KMS server binary (`cosmian_kms`) | Rust (Actix-web, tokio) | Critical |
-| KMIP protocol engine (`cosmian_kmip`) | Rust | High |
-| JWT/JWKS authentication middleware | Rust (jsonwebtoken, reqwest) | High |
-| Database backends (SQLite, PostgreSQL, Redis-findex) | Rust (sqlx, redis) | High |
-| CLI client (`ckms`) | Rust (clap) | Medium |
-| WASM client | Rust → WASM | Medium |
-| Web UI | React 19 / TypeScript / Ant Design | Medium |
-| OpenSSL 3.6.x (custom build) | C (bundled, vendored) | High |
-
-### 1.2 Out of scope
-
-- Physical HSM devices (Utimaco, Proteccio, Crypt2Pay) — covered by vendor certifications
-- Third-party cloud services (AWS XKS, Azure EKM, GCP CMEK) — covered by cloud-provider SLAs
-- Infrastructure layer (OS, network) — covered by deployment hardening guides
-
-### 1.3 Methodology
-
-This audit combines:
-
-1. **Automated static analysis** — `cargo audit`, `cargo deny`, `semgrep`, `gitleaks`, `grep`-based pattern checks (orchestrated by `.mise/scripts/audit/multi_framework.sh`)
-2. **Manual code review** — targeted review of authentication, cryptographic key handling, input parsing, and inter-service communication paths
-3. **Integration testing** — Rust `#[test]` modules in `crate/clients/clap/src/tests/security/` and `crate/server/src/middlewares/jwt/jwks.rs`
-4. **Control gap analysis** — mapping findings to each framework's control catalogue

-
-### 5.1 Assurance level mapping
-
-| Level | Requirement | KMS evidence |

-## 6. OSSTMM
-
-The Open Source Security Testing Methodology Manual (OSSTMM) defines five security channels: **Human, Physical, Wireless, Telecommunications, Data Networks**. The KMS is primarily a data-network application.
-
-### 6.1 Data Networks channel
-
-| OSSTMM section | Test area | Finding | Status |
-|----------------|-----------|---------|--------|
-| 5.1 — Posture | Server does not broadcast version by default | Confirmed: no `Server:` header in default config | ✅ |
-| 5.3 — Enumeration | KMIP endpoint returns 422 (not 404) for invalid bodies | `curl -X POST -d '{}' .../kmip/2_1` → 422 | ✅ |
-| 5.4 — Visibility | Sensitive fields masked in debug output | DB URL password → `****`; TLS passphrase masked | ✅ |
-| 5.6 — Access | CORS headers do not reflect attacker origin | CORS tests `cors_config.rs` (C1–C3) confirm | ✅ |
-| 5.7 — Trust | JWKS source must use HTTPS | `validate_jwks_uris_are_https()` enforced at startup | ✅ |
-| 5.8 — Controls | SSRF via open redirect blocked | `Policy::none()` on JWKS client; SR1 test confirms | ✅ |
-| 5.10 — Process | Batch request count mismatch handled gracefully | Batch abuse tests B1–B5 in `batch_abuse.rs` | ✅ |
-| 5.11 — Configuration | No wildcard CORS; no hard-coded credentials | Code scans pass; `deny.toml` bans enforced | ✅ |

-### 6.2 Residual risk summary
-
-| Risk area | Residual risk | Mitigation |
-|-----------|--------------|------------|
-| MFA enforcement | Low–Medium | Depends on OIDC provider configuration |
-| SQLite backup integrity | Low | WAL mode; deployment guide recommends periodic backups |
-| Rate limiting | Low | Not implemented at KMS level; recommend reverse-proxy (nginx, Caddy) |
-| Side-channel attacks | Very low | FIPS provider; constant-time primitives via OpenSSL |

- access.rs: correct stale CryptoOfficerConfig doc that claimed 'No
  cryptographic use' — active CO can Encrypt/Decrypt/Sign/MAC/Hash
  (CO candidate is already Operator; promotion must not reduce rights).
  Document blast radius: active CO is a global crypto oracle, all
  accesses audit-logged at ERROR target=audit.

- permissions.rs: document the peer-revocation trust model — dormant
  candidates can revoke active COs deliberately (break-glass path:
  prevents a situation where a compromised active CO cannot be revoked
  because no other active CO exists). No behavior change.

- CHANGELOG/feat_split_key.md: remove false claim that activation errors
  are 'propagated with ?'. Auto-activation is intentionally non-fatal:
  key is stored unconditionally; failures are WARN-logged with a pointer
  to the manual activation endpoint (fail-secure).

Subject: [PATCH 101/181] fix(permissions): replace stale 'privileged_users'
 terminology in error messages

Rename error strings in grant_access, revoke_access and the doc comment on
enforce_create_permission to use 'Crypto Officer' / 'crypto_officer.users'
instead of the removed 'privileged_users' field.

Addresses PM-8 from PR #991 review.

Subject: [PATCH 102/181] docs(ceremony): correct dual-control description to
 match actual server check

The server rejects activation only when ALL shares belong to the activating
candidate (solo self-activation guard). It does not require the candidate to
own zero shares. Align key_ceremony.md step 6 and the CryptoOfficerActivate
doc comment to reflect the real invariant.

GrantAccess and RevokeAccess are custom server routes, not KMIP operations.
They are owner-scoped: only the object owner can manage ACLs on their objects.
The CO ownership bypass does not extend to ACL management on foreign objects.
Remove them from the CO column and add an explanatory note.

PM-2: dormant CO candidates (listed but not yet ceremony-activated) pass
enforce_create_permission by design — they need Create/Import to complete the
ceremony prerequisite (ceremony vicious-circle break).

PM-3: Rekey routes through this gate because it creates a new Managed Object.
When crypto_officer.users is configured, object ownership alone does not grant
Rekey — the asymmetry vs Destroy/Revoke/SetAttribute is intentional.

CreateKeyPair, Register, ReKeyKeyPair, CreateSplitKey, JoinSplitKey have no
KmipOperation enum variant. The CryptoOfficer arm was falling through to an
implicit Ok(()) for these tags — undocumented and unaudited. Route them through
enforce_create_permission (same as the Operator arm) to make the allow path
explicit, consistent, and auditable. Active COs always satisfy this gate since
they are listed in crypto_officer.users.

 for Locate (PM-6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The find_all vs find swap at the top of locate() is a real CO ownership bypass:
active COs receive all matching objects regardless of ownership/grants, while
non-COs only see owned/granted objects. The bypass only manifests as a
difference in the *returned UID list* — not in exit code — so testing requires
diffing result sets across callers, not just checking success.

The ownership bypass (user_can_perform_operation) covers KMIP key-lifecycle
operations only. Crypto operations (Encrypt/Decrypt/Sign/…) route through
is_owm_authorized_with_get_wildcard, which checks ownership or explicit grants
and has no CO bypass. The previous doc claimed 'global encrypt/sign/decrypt
oracle' combined with ownership bypass — this was incorrect. An active CO can
only use crypto ops on keys they own or have been explicitly granted.

 ERROR, add session_id correlation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F-6: upgrade CreateSplitKey share-stored log and ceremony source-key
destruction log from info!() to tracing::error!(target: 'audit', ...)
so that split-key events are captured by SIEM/audit sinks regardless of
the runtime log level filter (CWE-778 Missing Logging of Critical
Operations).

F-7: fix misleading 'currently a no-op' doc comment on
CryptoOfficerConfig::validate() — the n>=3 guard was already enforced
by co.validate() in server_params.rs; only the doc was stale.

F-8: generate a UUIDv4 ceremony_session_id before the share loop in
create_split_key() and stamp it on every share audit entry, enabling
cross-share correlation in audit logs. Generate a join_session_id in
join_split_key() for the same reason.

Update log-reference.md with new error-level audit entries and their
variable/notes documentation.

 ### `cosmian_kms_server_database`
 

From ecb81d88714b9d7676d03c5d6966d73b60ef95c9 Mon Sep 17 00:00:00 2001
From: Manuthor 
Date: Thu, 20 Aug 2026 12:20:05 +0200
Subject: [PATCH 109/181] fix(ceremony): F-2 + F-3 + F-9 security fixes for CO
 split-key ceremony
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F-9 — Enforce activated_by uniqueness in crypto_officer_activations:
- query.sql (PostgreSQL): add `activated_by VARCHAR(255)`, update INSERT,
  add partial unique index: CREATE UNIQUE INDEX ON (activated_by) WHERE revoked_at IS NULL
- query_mysql.sql: add column, update INSERT, add migration queries;
  uniqueness enforced at application layer (MySQL lacks partial-index support)
- PermissionsStore trait: add `activated_by: &str` to
  `activate_crypto_officer_ceremony()`
- sqlite.rs / pgsql.rs / mysql.rs: idempotent startup migration (ALTER TABLE),
  pass `activated_by` through to the INSERT
- redis_with_findex.rs: pass `activated_by` (captured in sealed payload)
- database_permissions.rs: thread `activated_by` from join_split_key caller
- pgsql.rs tests: strip `postgresql://credentials@` from test fixtures so
  lychee does not fail on comma-separated multi-host port strings
- lychee.toml: exclude Ubuntu manpages + ETSI (flaky/bot-blocking); remove
  stale workaround entries (root cause fixed in test fixtures)

F-2 — Compensating delete when CO ceremony activation fails:
- In JoinSplitKey: when `perform_crypto_officer_ceremony_activation` fails,
  delete the just-stored reconstructed key (`kms.database.delete`)
- Log the rollback at `error!(target="audit")` with session_id, uid, error
- If the delete itself fails: log a second CRITICAL audit event for SIEM
- Return `Err(e)` — JoinSplitKey fails atomically; orphan prevention

F-3 — Optional AES-KW share wrapping via ceremony_wrapping_key_id:
- `CryptoOfficerConfig.ceremony_wrapping_key_id: Option`
- CLI flag: `--ceremony-wrapping-key-id` / env: `KMS_CEREMONY_WRAP_KEY_ID`
- Wired through `RolesConfig` → `CryptoOfficerConfig` in server_params
- CreateSplitKey: retrieves AES wrapping key, RFC 5649 wraps each share's
  bytes before DB storage, stamps `x-cosmian-share-wrapping-key` attr
- JoinSplitKey: detects attribute, unwraps bytes before XOR reconstruction
- `extract_key_bytes` promoted to `pub(crate)` for reuse in JoinSplitKey
- `Box::pin(create_split_key(...))` at call-site (future size limit)
- key_ceremony_tests.rs: add `ceremony_wrapping_key_id: None` to structs

 # CHANGELOG — feat/split_key
 
-## Features — Key Ceremony (XOR n-of-n split knowledge)
-
-- **Split-key ceremony for Crypto Officer role** (NIST SP 800-57 Part 2 Rev 1 §4.6 split knowledge):
-  `CreateSplitKey` and `JoinSplitKey` KMIP 2.1 operations implement XOR-based secret sharing.
-  All $n$ shares are required to reconstruct; threshold always equals total parts (n-of-n scheme).
-- **Config-driven ceremony**: `[roles]` section gains `crypto_officer_require_ceremony`, `ceremony_secret`
-  (hex-encoded 32-byte AES-256 key for GCM sealing), `crypto_officer_users`. When enabled, ceremony
-  candidates are inactive until all shares are joined via `JoinSplitKey`.
-- **Automatic share tagging**: shares created by ceremony candidates carry `x-cosmian-crypto-officer-ceremony`
-  vendor attribute tag for automatic ceremony detection.
-- **Active record management**: `crypto_officer_activations` table persists ceremony records with
-  sealed payload (AES-256-GCM via KDF-derived keys), activated\_by/participants/key\_hash tracking,
-  revoke support with `revoked_at`/`revoked_by`.
-
-## Security Improvements
-
-- **Zeroization of key material**: `xor_split` / `xor_join` now use `Zeroizing>` throughout;
-  heap memory wiped on drop. Shares consumed via `into_iter()` (no clone), leaving a single
-  zeroized copy. Derived `CeremonyKeys.obfuscation_key` zeroed on drop via explicit `Drop` impl.
-- **`ceremony_secret` never logged**: custom `Debug` impl for `RolesConfig` masks `ceremony_secret`
-  as `""`; prevents secret exposure when `RUST_LOG=debug`.
-- **Compensating delete on activation failure**: `JoinSplitKey` now deletes the reconstructed
-  key from the DB when ceremony auto-activation fails, then returns the error.  Previously the failure
-  was non-fatal and the key persisted without an activation record — any user holding a Grant on the
-  resulting UID could access it, bypassing ceremony dual-control.  A second CRITICAL audit entry is
-  emitted if the compensating delete itself fails, enabling SIEM alerting.
-- **Optional AES-KW share wrapping at rest**: new config field `ceremony_wrapping_key_id`
-  (CLI `--ceremony-wrapping-key-id` / env `KMS_CEREMONY_WRAP_KEY_ID`).  When set, `CreateSplitKey`
-  wraps each share's bytes with the referenced AES key using RFC 5649 (NIST SP 800-38F) before writing
-  to the DB.  `JoinSplitKey` detects the `x-cosmian-share-wrapping-key` vendor attribute and unwraps
-  transparently.  When the KMS is HSM-backed, the wrapping key can be HSM-resident, providing
-  hardware-boundary protection equivalent to purpose-built HSM split-key solutions.
-- **Split-key audit logs elevated to ERROR**: `CreateSplitKey` share-stored and source-key
-  destroyed events, and the `JoinSplitKey` reconstructed-key-stored event, now emit at
-  `error!(target="audit")`.  This ensures they are captured by SIEM/audit sinks regardless of the
-  runtime `RUST_LOG` filter (CWE-778 mitigation).
-- **Corrected doc comment on `CryptoOfficerConfig::validate()`**: the method previously said
-  "currently a no-op" but the n≥3 guard was already implemented.  Doc updated to reflect the actual
-  enforced invariant.
-- **Ceremony session ID stamped on audit logs**: a `Uuid::new_v4()` ceremony session ID is
-  generated once per `CreateSplitKey` call and stamped on every audit log entry for that call.
-  Similarly, `JoinSplitKey` generates a join session ID.  This enables SIEM correlation of all shares
-  from a single ceremony split (NIST SP 800-57 Part 2 Rev 1 §4.6 audit requirements).
-- **DB-level uniqueness on `activated_by`**: `crypto_officer_activations` gains an
-  `activated_by VARCHAR(255)` column.  PostgreSQL/SQLite add a partial unique index
-  `WHERE revoked_at IS NULL` (at most one active record per user at DB level).  MySQL enforces at
-  application layer (no partial-index support).  Idempotent startup migrations handle upgrades of
-  existing databases.
-- **Strict permission enforcement on JoinSplitKey**: ceremony activation is attempted as an
-  auto-activation side-effect of `JoinSplitKey`. Activation failure is now **fatal** — the reconstructed
-  key is deleted on failure.
-- **Fail-secure unenrolled users**: when roles are configured, unknown users default to Operator
-  (minimum privilege) instead of unrestricted access (NIST SP 800-57 Part 2 Rev 1 §4.8).
-- **Prevent duplicate active ceremony records**: `activate_crypto_officer_ceremony` revokes prior active
-  records before insert; SELECT uses `ORDER BY activated_at DESC LIMIT 1` for deterministic retrieval.
-- **Complete `key_part_identifier` validation**: join verifies identifiers are unique and form `{1..=N}`,
-  preventing duplicate-share attacks that would produce garbage reconstructed keys.
-- **Explicit `UniqueIdentifier` handling**: `unwrap_or_default()` replaced with match on
-  `TextString` variant; non-text UIDs return clear `KmsError::InvalidRequest`.
-
-## Features — Role Model (Two-Role RBAC)
-
-- **Two-role model**: `Operator` (default, read/write crypto ops) and `CryptoOfficer`
-  (lifecycle + ownership bypass). Replaces earlier three-role design.
-- **CryptoOfficerConfig**: simplified from former multi-role structs; fields are
-  `users`, `require_ceremony`, `ceremony_secret` — no longer includes `total_parts` (removed as dead code).
-- **`UserId` type safety**: dedicated newtype wrapping `String` with `From<&str>`, `Deref`,
-  `PartialEq` for `&str`/`String`, plus `try_new()` rejecting empty strings. Serde derives added.
-- **`ObjectHandle<'a>` enum**: typed object ID classifier with `is_hsm()`, `hsm_parts()`, prefix matching
-  replacing the removed `has_prefix()` utility; used consistently across dispatch/permissions/HSM paths.
-
-## CLI (`ckms`)
-
-- `ckms access-rights crypto-officer status` — print CO role configuration and ceremony state
-  (`GET /access/crypto-officer/status`).
-- `ckms access-rights crypto-officer disable` — revoke active CO ceremony (requires active CO).
-- Docs updated in `documentation/docs/kms_clients/main_commands.md` (heading levels fixed, trailing
-  whitespace removed).
+## Features
+
+### Two-role RBAC (CryptoOfficer / Operator)
+
+Replaces the former `privileged_users` flat list with two FIPS 140-3 aligned roles:
+
+- **`Operator`** (default) — crypto-use ops: Encrypt, Decrypt, Sign, Verify, MAC, Hash, Locate, GetAttributes.
+- **`CryptoOfficer`** — key-lifecycle ops + ownership bypass: Create, Import, Certify, Rekey, Activate, Revoke, Destroy, Get, Export, SetAttribute, …
+- Unknown users default to `Operator` (fail-secure, NIST SP 800-57 Pt 2 §4.8).
+- New `[roles]` TOML section; migration: rename `privileged_users` → `crypto_officer_users` under `[roles]`.
+
+### Split-key ceremony (XOR n-of-n)
+
+`CreateSplitKey` and `JoinSplitKey` KMIP 2.1 (and 1.4) operations implement XOR n-of-n secret sharing:
+
+- Shares tagged `x-cosmian-crypto-officer-ceremony`; each owned by a different CO candidate.
+- `JoinSplitKey` with all ceremony shares auto-activates the CO role (writes `crypto_officer_activations`).
+- Activation records AES-256-GCM sealed from `ceremony_secret` (hex 32-byte); `ceremony_secret` masked in logs.
+- **Optional AES-KW share wrapping** (`ceremony_wrapping_key_id` / `KMS_CEREMONY_WRAP_KEY_ID`): each share encrypted with RFC 5649 before DB write; unwrapped transparently on `JoinSplitKey`. HSM-backed key supported.
+- `ceremony_key_id` (`KMS_CEREMONY_KEY_ID`) accepted by config parser for future KMS-object sealing key (ADP-26, not yet functional — use `ceremony_secret` in the meantime).
+
+### Revocation
+
+- **Self-revoke**: active CO calls `POST /access/crypto_officer/disable`.
+- **Peer revocation**: any CO candidate calls the same endpoint with `{ "target_user": "" }` to demote another active CO without server restart (NIST SP 800-152 FR:6.119).
+
+## Security
+
+- Zeroized key material throughout (`Zeroizing>`, `Drop` on `CeremonyKeys`).
+- **Compensating delete on activation failure**: reconstructed key deleted from DB if auto-activation fails; CRITICAL audit entry if the delete itself fails (prevents bypass via failed ceremony).
+- Audit events for `CreateSplitKey`/`JoinSplitKey` elevated to `error!(target="audit")` (CWE-778 mitigation).
+- Per-call session UUID stamped on all ceremony audit entries for SIEM correlation.
+- DB partial unique index on `activated_by WHERE revoked_at IS NULL` (PostgreSQL/SQLite); application-level guard on MySQL.
+- Complete `key_part_identifier` validation: shares must form `{1..=N}` with no duplicates.
+- Ceremony candidates exempted from `Create`/`Import` restriction before ceremony completes (prevents bootstrap deadlock).

+## CLI
+
+- `ckms access-rights crypto-officer status` — show role config and ceremony state.
+- `ckms access-rights crypto-officer disable` — revoke active ceremony.
+- New `create-split-key` subcommand under the `crypto-officer` CLI group.
 
 ## Web UI
 
-- **Crypto Officer page** (`/ui/access-rights/crypto-officer`): status page showing role config,
-  ceremony activation state, CO user list, and Disable button (visible only when active ceremony exists;
-  requires active CO privileges). Menu label shortened from "Crypto Officer Role" to "Crypto Officer".
-- **Crypto Officer page fully localized**: all labels, descriptions, badges, tooltips, and ceremony
-  workflow steps are now translated via i18n, including Chinese (`zh-CN`). The menu entry
-  "Crypto Officer" is also localized.
-- **Split Key and Join Split Key pages localized and kept generic**: both dialogs
-  (`/ui/sym/keys/split` and `/ui/sym/keys/join`) render their headings, descriptions, labels,
-  placeholders, validation messages, and result text via i18n (English and Chinese). They no longer
-  reference the key ceremony or Crypto Officer role — the share count is always user-editable. The
-  corresponding "Split"/"Join" menu entries are also localized.
-- **Search Objects locate buttons across action forms**: key/object/certificate identifier inputs in
-  symmetric, RSA, EC, Covercrypt, MAC, PQC, FPE, certificate, attribute, object, and rotation-policy
-  dialogs now use the reusable `KeyIdInput` component so users can search and select existing objects
-  directly from the form, with object-type filtering where applicable.
-- **SplitKey / JoinSplitKey dialogs**: removed unsupported "Polynomial Sharing GF(2^8)" (Shamir) option;
-  now defaults to XOR method. **Threshold (k) input removed** and **method selector removed** —
-  only XOR n-of-n is supported. Renamed "Total Parts" to "Number of Shares". Updated descriptions
-  to clarify all shares are required.
-- **JoinSplitKey dialog**: method selector removed (XOR is the only option). Description updated
-  to clarify all shares are required for n-of-n reconstruction.
-- **Dark theme aligned with the documentation site**: the Web UI dark theme now reuses the same
-  mdBook "navy" palette as `docs.cosmian.com` (near-black `#161923` background, `#bcbdd0` text,
-  `#282d3f` sidebar) instead of the previous gray surfaces. The light theme uses the darker brand
-  orange `#c73f1b` for the primary accent. The sidebar menu and all surfaces now switch together
-  with the light/dark toggle.
-- **Contrast fixes (WCAG AA)**: resolved unreadable colour combinations in dark mode — dark text on
-  the black background (`text-gray-800`, `text-blue-800`, `text-red-800`), light-gray helper text on
-  white, near-invisible borders, and the low-contrast orange/teal accents — now meet AA contrast in
-  both themes.
-
-## Bug Fixes
-
-- **Ceremony candidate exemption extended to Create/Import**: ceremony candidates (users in
-  `crypto_officer_users` with `require_ceremony = true`) can now create and import keys before
-  completing the ceremony. Previously only `CreateSplitKey`/`JoinSplitKey` were exempted, causing
-  a chicken-and-egg problem where candidates could not create the master key to split.
-  The exemption remains scoped to ceremony candidates only — full CO privileges (ownership bypass)
-  still require ceremony completion.
-- **Missing test data restored**: re-added deleted config files in `test_data/configs/server/client/`
-  (`auth_plain*.toml`, `jwt.toml`) required by integration tests (`test_kms_all_authentications`,
-  `test_vendor_id_in_vendor_attributes`).
-- **Lychee exclude patterns added**: example OAuth URLs in config templates excluded from link checking.
-  Non-routable IP `1.2.3.4` (used in forward proxy tests) excluded from link checking.
+- **Crypto Officer page**: status dashboard (ceremony state, active CO list, custodian count); configurable base key ID with live share-UID preview (`#1`, `#2`…); peer-revocation dropdown (visible to active CO only); ceremony activation form.
+- **SplitKey / JoinSplitKey dialogs**: Shamir option removed; only XOR n-of-n supported. "Total Parts" renamed to "Number of Shares". Threshold and method selectors removed.
+- **Dark theme**: aligned to mdBook Eviden palette (`#161923` bg, `#bcbdd0` text, `#282d3f` sidebar, orange `#f14611`). All contrast ratios WCAG AA.
+- **Sidebar fixes**: sub-menus visible when sidebar is collapsed; collapse trigger button color corrected in light theme.
 
 ## Testing
 
-- **7 ceremony vector tests**: `create_split_key_xor` round-trip (2-of-2, 3-of-3), `join_split_key_*`
-  variants covering consistency checks, failure scenarios, and full lifecycle activate→disable→deny.
-- **11 RBAC CLI tests** (`rbac_tests.rs`): verify the two-role model per ADR-2026-06-24:
-  CO can create/export/destroy keys; CO **cannot** encrypt/decrypt (Operator-only); Operator can
-  encrypt/decrypt with grant; Operator cannot create/export/destroy keys; CO ownership bypass;
-  Operator needs explicit grant; grant/revoke access flow.
-- **7 RBAC E2E tests** (`rbac-flow.spec.ts`): SplitKey/JoinSplitKey UI loading, access control
-  page smoke tests, grant access flow via UI, Crypto Officer page accessibility.
-- Server config TOMLs: `cert_auth_crypto_officer.toml`, `cert_auth_crypto_officer_ceremony.toml`,
-  `cert_auth_operator_only.toml`, `rbac/*.{toml}` for role-separation tests.
-- Pre-commit hook fixes applied: shellcheck SC2329/SC2086/SC2119, Go tab→space normalization,
-  CRLF→LF line endings, Python quote style, trailing whitespace, trailing newlines.
+- 7 ceremony vector tests (2-of-2, 3-of-3 round-trips, failure scenarios, full activate→disable→deny lifecycle).
+- 11 RBAC CLI tests (`rbac_tests.rs`): CO/Operator permission matrix per ADR-2026-06-24.
+- 7 RBAC E2E tests (`rbac-flow.spec.ts`): UI smoke tests for split-key and CO pages.
 
 ## Documentation
 
-- **Key ceremony guide** (`documentation/docs/configuration/authorization/key_ceremony.md`): explains
-  two-role RBAC, XOR n-of-n split knowledge, NIST references (SP 800-57 Pt 2 §4.6–§4.8), Mermaid
-  sequence diagrams for 4-phase ceremony flow, and CLI quick reference.
-- **Authorization reference** (`documentation/docs/configuration/authorization.md`): updated role model,
-  operation tables, permission evaluation order, and normative requirements table.

SSRF via attacker-controlled CRL Distribution Points in KMIP Validate/Import (COSMIAN-2026-020).

- Add validate_crl_url() in crate/server/src/core/certificate/mod.rs:
  blocks private/loopback/link-local IPs and internal hostnames before
  any network I/O; allows HTTP and HTTPS (RFC 5280 CDPs are typically HTTP).
- Rewrite get_crl_bytes() in crate/server/src/core/operations/validate.rs:
  - Call validate_crl_url() before every HTTP(S) fetch
  - Exempt kms_public_url prefix (server's own CRL endpoint is trusted)
  - Add reqwest::redirect::Policy::none() (no redirect following)
  - Add 30-second request timeout
  - Cap response body at 10 MiB (CRL_MAX_RESPONSE_BYTES)
  - Reject bare filesystem paths and file:// URIs in production
  - Allow file:// in #[cfg(any(test, feature = "insecure"))] for test fixtures
  - Use ? on .send() so network failures stay ClientConnectionError (soft-fail)
- Add kms_public_url param to verify_crls() and get_crl_bytes(); pass from
  both validate_operation() and import_operation() via kms.params
- Add 10 regression tests SR-CRL-01 through SR-CRL-10 covering all vectors
- Add COSMIAN-2026-020 entry to SECURITY.md
- Exclude RFC-1918/link-local test URLs from lychee link checker

+
+**Summary:** Cosmian KMS fetched CRLs from URLs embedded in X.509 CRL Distribution Points (CDPs) during KMIP `Validate` and `Import` operations without applying any SSRF mitigations. The `get_crl_bytes()` function in `crate/server/src/core/operations/validate.rs` accepted arbitrary `http://` URLs (including loopback, private RFC-1918, and link-local addresses), followed HTTP redirects unconditionally, read the full response body without a size cap, and treated non-URL CDP values as local filesystem paths — allowing arbitrary file reads. A secondary vector existed via `file://` scheme URLs, which were explicitly converted to filesystem paths.
+
+This is a separate code path from COSMIAN-2026-009 (Google CSE `original_kacls_url` SSRF); the fix for that advisory did not cover CRL Distribution Point fetches.
+
+**Impact:** A post-authentication attacker with `Validate` or `Import` permission could:
+
+- Probe internal HTTP services reachable from the KMS host (confirmed blind SSRF via PoC on v5.26.0).
+- Access cloud metadata endpoints (e.g. `169.254.169.254`) from cloud-hosted deployments.
+- Read arbitrary local files readable by the KMS process via bare filesystem paths or `file://` URIs.
+- Cause denial of service via a slow or unbounded HTTP response body (no size cap, no timeout).
+
+**Mitigation:** Upgrade to 5.27.0. The fix adds `validate_crl_url()` in `crate/server/src/core/certificate/mod.rs` (HTTPS and HTTP allowed; private, loopback, link-local IPs and internal hostnames rejected), applies `reqwest::redirect::Policy::none()` and a 30-second timeout to the CRL-fetch client, caps responses at 10 MiB, and removes filesystem-path and `file://` CRL resolution in production builds (`file://` remains available in `#[cfg(test)]` only). Ten regression tests (SR-CRL-01 through SR-CRL-10) cover all mitigations.

Subject: [PATCH 129/181] fix(test): use temp file in sr_crl_10 instead of
 test_data submodule

The test relied on test_data/certificates/openssl/prime256v1.crl which is
not available in all CI environments (submodule not checked out for some
jobs). Replace with a self-contained tempfile::NamedTempFile write so the
test is hermetic on every runner. Rephrase inline comment to avoid lychee
false-positive on file:// placeholder text.

Subject: [PATCH 130/181] feat: implement auto CRL refresh and persist CRLs in
 DB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- fix(crl): use find_all in find_revoked_certificates so CRL includes
  certs from all users, not just those accessible to the requesting user
- feat(crl): add CO guard at generate_crl entry; audit-log CO bypass
- feat(crl): add KMS::find_active_co() helper (first active CO or None)
- feat(crl): auto-regenerate issuer CRL on certificate revocation when
  kms_public_url is set; uses find_active_co for signer identity;
  errors are warn-logged and never fail the Revoke operation
- feat(db): add crls table (SQLite/PgSQL/MySQL/Redis) with upsert_crl
  and get_crl; table created at server boot alongside all other tables
- feat(crl): persist signed CRL to DB after every generate_crl call
- feat(crl): get_cached_crl loads from DB on cold start (no 404 after
  server restart); public CDP endpoint immediately available
- test(crl): add test_crl_contains_certs_from_all_users — regression
  guard for find_all fix: 3 certs owned by 2 users, CRL must have 3
  entries; reverts to 1 without fix
- fix(lychee): exclude crate/ from link checks to avoid false-positive
  parse errors on multi-host PostgreSQL connection strings in comments
- docs(pki): sync pki.md with auto-CDP injection, public CDP endpoint,
  CO requirement, auto-regen on revoke, DB persistence, kms_public_url
- docs(revoke): remove stale 'revocation reason not maintained' sentence
- docs(tables): add crls table (count 5->6, schema, ERD, Redis note)
- docs(log-reference): add new auto-CRL warn/info/audit log entries

 ## Links between tables
 
 - `objects.id` is referenced by `read_access.id` and `tags.id`: one object can have many access rows and many tags.
 - `objects.wrapping_key_id` points to `objects.id`: a wrapping key is itself an object, and many objects can be wrapped by the same key.
+- `crls.issuer_id` logically references `objects.id` (the CA certificate): one CA has at most one current CRL row.
 - `objects.owner` and `read_access.userid` hold user identifiers.
   Users are authenticated identities and are **not** stored in a dedicated table.
 - `parameters` and `crypto_officer_activations` are standalone and do not reference `objects`.

+### Automatic CRL regeneration on revocation
+
+When `kms_public_url` is set in `kms.toml`, the server **automatically regenerates**
+the issuer's CRL whenever a certificate is revoked via the `Revoke` operation.
+
+```toml
+# kms.toml — enables CDP auto-injection and auto-CRL regeneration
+kms_public_url = "https://kms.example.com"
+```
+
+The regeneration runs inline before the `Revoke` response is returned, using the
+first active Crypto Officer identity (or `default_username` in no-CO deployments).
+The updated CRL is immediately available at the public CDP endpoint:
+
+```http
+GET /public/certificates/{issuer_id}/crl    # no authentication required
+```
+
+If no active CO is found when one is required, the regeneration is skipped and a
+`warn`-level log is emitted — the CRL will be refreshed on the next manual
+`generate-crl` call or after a CO ceremony completes.

Subject: [PATCH 132/181] feat(crl): configurable validity, Cache-Control
 headers, background refresh scheduler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements 3 features bringing CRL lifecycle parity with Vault PKI, EJBCA,
AWS Private CA, and DigiCert:

1. Configurable CRL validity (--crl-default-validity-days, default 7).
2. Cache-Control + Expires headers on GET /public/certificates/{id}/crl.
   max-age = next_update - now - 60s. RFC 7234 / DigiCert CDN practice.
3. Background CRL refresh scheduler (spawn_crl_refresh_cron).
   Wakes every crl_refresh_check_hours (default 1). Regenerates CRLs

+
+## Status
+
+Proposed | **Accepted** | Rejected | Superseded | Deprecated
+
+## Context
+
+The Eviden KMS already supported certificate issuance (KMIP `Certify` operation) and
+revocation (KMIP `Revoke`). However, the revocation data was entirely internal to the KMS
+database. Any PKI relying party (TLS stack, browser, OCSP client) needed a Certificate
+Revocation List (CRL) to enforce revocation, and no such CRL distribution mechanism existed.
+
+Several constraints drove the design:
+
+- **RFC 5280 §3 / §5**: CRL Distribution Point (CDP) URIs embedded in certificates must be
+  reachable by unauthenticated relying parties. The KMS cannot require OAuth2/JWT credentials
+  for a CDP endpoint.
+- **RFC 5280 §5.2.3**: CRL Number extensions must be monotonically increasing across CRL
+  generations, including across server restarts.
+- **FIPS 140-3**: CRL signing must use only FIPS-approved algorithms. Authority Key
+  Identifier construction was previously relying on `EVP_sha1()` (not FIPS-approved for new
+  use) and had to be replaced.
+- **Multi-CA**: the KMS can host multiple independent CAs. The solution must be per-issuer,
+  not global.
+- **Operator UX**: operators must be able to configure a public-facing `kms_public_url` and
+  have CDP URIs auto-inserted into newly issued certificates without manual configuration.
+- **Cold-start availability**: the public CDP endpoint must be immediately available after a
+  server restart without requiring a manual `generate-crl` call.
+- **Access control**: because CRL generation enumerates *all* revoked certificates regardless
+  of ownership (bypassing user filters), it must be gated behind the Crypto Officer role when
+  CO users are configured.
+
+## Decision
+
+Implement a three-tier CRL architecture:
+
+### Tier 1 — Authenticated CRL generation endpoint
+
+`GET /certificates/{issuer_id}/crl` (requires authentication)
+
+- Signs a fresh X.509 v2 CRL using the CA's private key from the KMS key store.
+- Lists all certificates with `CertificateLink → issuer_id` and KMIP state `Deactivated` or
+  `Compromised`, regardless of owner (CO-only bypass).
+- Supports `format=der` (default, `application/pkix-crl`) and `format=pem`
+  (`application/x-pem-file`) query parameters.
+- Supports `validity_days` override (server default: 7 days, never < 1).
+- Uses a process-global atomic counter seeded from UTC Unix timestamp as CRL Number, guaranteeing
+  monotonic uniqueness across concurrent calls and server restarts.
+- Writes the signed CRL DER and `next_update` timestamp to the `crls` database table
+  (non-fatal on DB error — in-memory cache still works).
+- Populates a process-local `GENERATED_CRL_CACHE` (`LazyLock>>`) for fast re-serving.
+- Also exposed as a new CLI command `ckms certificates generate-crl` and Web UI action
+  (Certificates → Certs → Generate CRL).
+
+### Tier 2 — Unauthenticated public CDP endpoint
+
+`GET /public/certificates/{issuer_id}/crl` (no authentication)
+
+- Serves pre-signed CRL DER bytes from the two-level cache (in-memory → DB fallback).
+- Returns HTTP 404 with a diagnostic message until the cache is primed.
+- Sets `Last-Modified` (RFC 7231 IMF-fixdate) and `Content-Disposition` headers.
+- Intended as the CDP URI in `crlDistributionPoints` extensions: `{kms_public_url}/public/certificates/{issuer_id}/crl`.
+- Does **not** sign fresh CRLs — it only serves the last signed bytes; no key material is
+  accessed on this path.
+
+### Tier 3 — Scheduled CRL auto-refresh
+
+A background cron task (`spawn_crl_refresh_cron`) wakes every `crl_refresh_check_hours`
+(default: 24 h, 0 = disabled) and regenerates any stored CRL whose `next_update` timestamp
+falls within `crl_refresh_overlap_hours` (default: 48 h) of the current time.
+
+This models the *CRL overlap window* pattern (EJBCA "CRL Overlap Time", AWS PCA 1-day overlap):
+the new CRL is signed before the old one expires, so relying parties always have a valid CRL
+even if no revocation event triggered a manual regeneration.
+
+The cron runs in its own OS thread with a single-threaded Tokio runtime to avoid contention
+with the main Actix-web executor. It is shut down cleanly via a `oneshot::Sender<()>` held by
+the server startup routine.
+
+### Tier 4 — Auto-injection of CDP extension
+
+When `kms_public_url` is configured, the `Certify` operation automatically inserts a
+`crlDistributionPoints` extension (RFC 5280 §4.2.1.13) pointing to the public CDP endpoint
+into newly issued non-self-signed certificates, unless the subject or the caller already
+provides a CDP.
+
+Self-signed certificates receive `id-ce-noRevAvail` (RFC 9608) instead, since self-signed
+certs cannot appear in a CRL they also sign.
+
+Re-certifications that already carry a CDP are not modified.
+
+### FIPS-safe AKI construction
+
+The `AuthorityKeyIdentifier` CRL extension (RFC 5280 §5.2.1) is constructed manually
+using a low-level SHA-1 hash of the issuer's SPKI DER via `openssl::sha::Sha1`
+(C interface, bypasses the FIPS provider check). This approach is intentional:
+the AKI is a key identifier, not a cryptographic commitment; RFC 5280 §4.2.1.1 explicitly
+permits SHA-1 for this use; and the FIPS provider's prohibition covers digest *algorithms
+in security services* (e.g. signatures), not identifier derivation. The CRL signature itself
+uses only FIPS-approved algorithms.
+
+### Database persistence (`crls` table)
+
+A new `crls` table stores `(issuer_id, crl_der, crl_number, generated_at, next_update)`.
+This enables cold-start recovery: on the first request to the public CDP after a restart,
+the server loads the last persisted CRL from DB into the in-memory cache. The DB write in
+`generate_crl` is best-effort — a DB failure is logged as `WARN` and does not fail the
+authenticated CRL generation request.
+
+## Consequences
+
+### Positive
+
+- **POS-001**: Full RFC 5280 §5 CRL distribution chain from issuance to revocation to
+  relying-party validation, without requiring any external OCSP infrastructure.
+- **POS-002**: Unauthenticated CDP endpoint aligns with RFC 5280 §3 requirements; no
+  credential leakage risk since it serves pre-signed, immutable DER bytes.
+- **POS-003**: CRL Number monotonicity guaranteed across restarts via unix-timestamp seed;
+  no DB round-trip required for counter state.
+- **POS-004**: Operator configuration is minimal — setting `kms_public_url` is sufficient
+  to activate end-to-end CDP injection; no per-CA configuration needed.
+- **POS-005**: FIPS compliance maintained for AKI construction (SHA-1 via C bypass) without
+  compromising the overall FIPS posture.
+- **POS-006**: DB persistence ensures the public CDP endpoint survives server restarts
+  without requiring a warm-up call.
+- **POS-007**: Crypto Officer gating on `generate_crl` (when COs are configured) is
+  consistent with the existing access-control model for privileged listing operations.
+
+### Negative
+
+- **NEG-001**: The public CDP endpoint serves *stale* CRLs between `generate-crl` calls.
+  Relying parties may not see a revocation until the CA owner regenerates the CRL. This
+  is the standard CRL trade-off (vs. OCSP stapling); operators must configure appropriate
+  `validity_days` and/or automate CRL regeneration on revocation events.
+- **NEG-002**: The in-memory cache is per-process. Multi-instance deployments behind a
+  load balancer will have independent caches; only the instance that handled the last
+  `generate-crl` request has the fresh CRL in RAM (all instances share the DB-persisted
+  copy after a DB write succeeds).
+- **NEG-003**: The `crls` table introduces a new DB schema dependency. Existing deployments
+  require a schema migration before upgrading.
+- **NEG-004**: CRL generation requires the issuer's private key to be accessible in the KMS
+  key store at request time. HSM-backed keys add latency on each `generate-crl` call.
+
+## Alternatives Considered
+
+### OCSP (Online Certificate Status Protocol, RFC 6960)
+
+- **ALT-001 Description**: Deploy an embedded OCSP responder alongside the KMS. Relying
+  parties query per-certificate status in real time.
+- **ALT-002 Rejection Reason**: OCSP requires per-request signing with a short-lived OCSP
+  signing certificate, nonce handling, and significant additional protocol surface area.
+  CRL is the simpler baseline required by most enterprise PKI stacks and is a prerequisite
+  before OCSP can be considered. OCSP stapling can be added as a future enhancement.
+
+### Auto-regenerate CRL on every Revoke call
+
+- **ALT-003 Description**: Trigger `generate_crl` automatically every time a `Revoke`
+  operation completes, keeping the public CDP always current.
+- **ALT-004 Rejection Reason**: Revoke is a hot path; signing a CRL requires private key
+  access (potentially HSM) and a DB round-trip. Coupling this to every revocation would add
+  latency and increase HSM wear. The current design keeps CRL generation an explicit,
+  operator-controlled operation. Automatic refresh can be added as an optional feature flag
+  in a future ADR.
+
+### Store CRL in object store / S3
+
+- **ALT-005 Description**: Push signed CRL bytes to an object store (S3, GCS) and serve
+  from there, decoupling CRL distribution from the KMS process.
+- **ALT-006 Rejection Reason**: Introduces an external dependency and complicates
+  deployment. The KMS already owns a database with reliable persistence; the `crls` table
+  is the simplest consistent extension of existing infrastructure.
+
+### External CRL signer (offline CA)
+
+- **ALT-007 Description**: Keep the signing CA key offline; export a signing request to an
+  offline process.
+- **ALT-008 Rejection Reason**: Out of scope for the KMS, which is designed to be the
+  online CA. Offline CA workflows require a separate product and are not addressed by this
+  ADR.
+
+## Implementation Notes
+
+- **IMP-001**: `GENERATED_CRL_CACHE` is a `LazyLock>>`.
+  The `RwLock` is async-aware to avoid blocking the Actix-web thread pool on cache reads
+  (which are the hot path for the public endpoint).
+- **IMP-002**: `CRL_SEQUENCE_COUNTER` is a `LazyLock` seeded from
+  `OffsetDateTime::now_utc().unix_timestamp()`. In the unlikely event of two processes
+  starting within the same second and both serving the public endpoint, a counter collision
+  is possible. Operators running active-active HA must use a shared sequence source (DB
+  sequence) or accept a one-second collision window; this is noted as a known limitation.
+- **IMP-003**: The `build_crl` function in `crate/crypto/src/openssl/crl.rs` encapsulates
+  all OpenSSL CRL construction. It is covered by FIPS-mode integration tests.
+- **IMP-004**: All new DB operations (`get_crl`, `upsert_crl`) implement both the SQLite
+  and PostgreSQL backends and are covered by the standard multi-backend test matrix.
+- **IMP-005**: The `encode_der_length` helper in `build_certificate.rs` now returns
+  `KResult<()>` to prevent silent truncation of CDP URIs longer than 65535 bytes.
+- **IMP-006**: Success criterion — `test_crl_validation_lifecycle` end-to-end test passes
+  on all DB backends (SQLite, PostgreSQL) in both FIPS and non-FIPS modes.

Subject: [PATCH 133/181] fix: follow RFC 5280 for RemoveFromCRL reason mapping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RFC 5280 §5.3.1 explicitly restricts removeFromCRL (reason code 8) to
delta CRLs only.  The KMS generates only complete CRLs; emitting reason
code 8 in a complete CRL violates the standard.

Fix: map RemoveFromCRL to Unspecified so the reasonCode extension is
omitted from CRL entries per RFC 5280 §5.3.1 (prefer absent over
unspecified(0)).

Also:
- Fix test_toml: add the 3 new CRL params to the expected TOML string
- Remove competitor mention from CRL validity doc comment
- Fix clippy: replace const-after-statement + indexing-slicing in
  test_crl_remove_from_crl_omits_reason_code

Subject: [PATCH 134/181] test(crl): verify CRL generation when CO role is
 disabled

Adds test_crl_without_co_full_lifecycle:
- Uses the plain default server (no crypto_officer_users configured)
- Owner creates a CA, issues 3 leaf certs, revokes all 3
- Asserts auto-regen on revoke fires (falls back to default_username)
- Asserts authenticated GET /certificates/{id}/crl returns 3 entries
- Asserts unauthenticated GET /public/certificates/{id}/crl returns 200
  with 3 entries and a Cache-Control header

This proves the single-admin fallback path in generate_crl() works
correctly when no CO is configured.

Subject: [PATCH 135/181] fix(ui): use public CRL endpoint to include certs
 from all users
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The authenticated GET /certificates/{id}/crl endpoint:
- Requires Crypto Officer role when crypto_officer_users is configured
- Would fail with 401 for non-CO users in multi-user deployments

The public GET /public/certificates/{id}/crl endpoint:
- Requires no authentication
- Serves the auto-generated CRL (kept fresh by the revocation trigger
  and the background refresh scheduler)
- The CRL was built with find_all() so it includes every revoked
  certificate issued by this CA regardless of ownership

UI changes:
- CertificateGenerateCrl.tsx: switch to /public/certificates/{id}/crl
- Remove validity_days field (not used by the public endpoint)
- Add informational Alert explaining auto-regen behaviour
- DER→PEM conversion done client-side (public endpoint returns DER)
- Better 404 error message guiding the user to revoke a cert first
- Rename 'Generate CRL' → 'Download CRL' in menu and UI

Server change:
- Update the 404 message on the public endpoint to mention auto-regen
  instead of sending users back to the authenticated endpoint

Subject: [PATCH 149/181] fix(test): update test_toml expected string for
 CrlConfig TOML section

After the CrlConfig refactoring (commit a984a67a) the three crl_* fields
are now a nested struct. toml::to_string() therefore serialises them as a
[crl] section at the end of the TOML output instead of flat top-level keys.

Update the hardcoded expected string in test_toml to match:
  - remove crl_default_validity_days/crl_refresh_check_hours/
    crl_refresh_overlap_hours from the flat top-level section
  - add [crl] section at the end (after [vault])

Fixes CI failure: tests::test_toml on non-fips Windows job 97186811284.

-  CO users are configured.

 - Lists all certificates with `CertificateLink → issuer_id` and KMIP state `Deactivated` or

+  No Crypto Officer role is required — CRL content contains no private key material.
 - Supports `format=der` (default, `application/pkix-crl`) and `format=pem`
   (`application/x-pem-file`) query parameters.
-- Supports `validity_days` override (server default: 7 days, never < 1).
-- Uses a process-global atomic counter seeded from UTC Unix timestamp as CRL Number, guaranteeing
-  monotonic uniqueness across concurrent calls and server restarts.
+- Supports `validity_days` override (server default: 7 days, range: 1–365, configured via

+- CRL Number is assigned from a per-`KMS`-instance `Arc` seeded at startup from
+  `max(unix_timestamp, db_max_crl_number + 1)`, guaranteeing strict monotonicity across both

+# Revocation & CRL Distribution
+
+Certificate revocation in the Eviden KMS follows the two-phase model defined by
+[RFC 5280](https://www.rfc-editor.org/rfc/rfc5280):
+
+1. **Revoke** a certificate — the KMIP `Revoke` operation marks the certificate
+   `Deactivated` or `Compromised` in the KMS database.
+2. **Publish** the revocation — the `Generate-CRL` operation (or automatic
+   post-revocation refresh) signs a fresh CRL that relying parties can fetch.
+
+## CRL generation
+
+The KMS generates X.509 v2 Certificate Revocation Lists (CRLs) per
+[RFC 5280 §5](https://www.rfc-editor.org/rfc/rfc5280#section-5).
+
+A CRL lists all certificates issued by a CA that have been revoked. The KMS
+automatically collects **all** revoked certificates — those in `Deactivated` or
+`Compromised` state with a `CertificateLink` pointing to the issuer — regardless
+of which user owns each certificate record in the KMS database, then signs the
+CRL with the CA private key.
+
+**CLI usage:**
+
+```bash
+ckms certificates generate-crl \
+  --certificate-id  \
+  --validity-days 7 \
+  --output-format pem \
+  --output-file /tmp/crl.pem
+```
+
+**REST endpoint (authenticated):**
+
+```http
+GET /certificates/{issuer_id}/crl?format=pem&validity_days=7
+```
+
+Returns `application/pkix-crl` (DER, default) or `application/x-pem-file` (PEM).
+
+!!! note "Access control"
+    Any **authenticated** user with `Get` access to the CA certificate may call
+    this endpoint — no Crypto Officer role is required. CRL content is public
+    information (RFC 5280 §3); the authentication check exists to prevent the CA
+    private key from being used as an unauthenticated signing oracle, not to
+    restrict access to the revocation list itself.
+
+The generated CRL includes:
+
+- **Authority Key Identifier** (AKI) — derived from the CA's `subjectKeyIdentifier`
+  extension if present, or from a SHA-1 hash of the CA's `SubjectPublicKeyInfo` DER.
+- **CRL Number** — monotonically increasing integer, seeded at startup from
+  `max(unix_timestamp, db_max_crl_number + 1)` to guarantee strict monotonicity
+  across server restarts (RFC 5280 §5.2.3).
+- Per-entry **CRL Reason Code** — mapped from the KMIP revocation reason stored at
+  revocation time (RFC 5280 §5.3.1).
+- Per-entry **Invalidity Date** — `GeneralizedTime`-encoded date of compromise when
+  available in object attributes (RFC 5280 §5.3.2).
+
+### Configuration
+
+```toml
+# kms.toml
+[crl]
+crl_default_validity_days = 7   # default CRL validity in days (1–365)
+crl_refresh_check_hours   = 1   # background refresh check interval; 0 = disabled
+crl_refresh_overlap_hours = 24  # pre-regenerate this many hours before expiry
+```
+
+All three keys may also be set as CLI flags or environment variables:
+
+```bash
+--crl-default-validity-days 7
+--crl-refresh-check-hours   1
+--crl-refresh-overlap-hours 24
+```
+
+## Automatic CRL regeneration on revocation
+
+When `kms_public_url` is set in `kms.toml`, the server **automatically regenerates**
+the issuer's CRL in the background whenever a certificate is revoked via the
+`Revoke` operation. The regeneration is fire-and-forget: it does not block the
+`Revoke` response, and any signing failure is logged at `WARN` level without
+affecting the revocation outcome.
+
+```toml
+# kms.toml — enables CDP auto-injection and auto-CRL regeneration
+kms_public_url = "https://kms.example.com"
+```
+
+The updated CRL is immediately available at the public CDP endpoint:
+
+```http
+GET /public/certificates/{issuer_id}/crl    # no authentication required
+```
+
+## Scheduled CRL refresh
+
+A background scheduler wakes every `crl_refresh_check_hours` (default: 1 h) and
+regenerates any stored CRL whose `nextUpdate` timestamp falls within
+`crl_refresh_overlap_hours` (default: 24 h) of the current time. This prevents
+relying parties from seeing an expired CRL during the window between the scheduled
+expiry and the next revocation-triggered regeneration.
+
+Set `crl_refresh_check_hours = 0` to disable the background scheduler entirely
+(CRLs will only be refreshed on explicit `generate-crl` calls or `Revoke` events).
+
+## CRL distribution points
+
+When `kms_public_url` is configured, the KMS **automatically injects** a
+`crlDistributionPoints` (CDP) extension into every CA-issued certificate, pointing
+to the server's own public CRL endpoint:
+
+```text
+https:///public/certificates//crl
+```
+
+You do **not** need to supply a CDP extension manually for KMS-issued certificates
+when `kms_public_url` is set.
+
+To override or set a custom CDP manually (e.g. for an external CA), add a
+`crlDistributionPoints` entry in the extension config file passed via
+`--certificate-extensions`:
+
+```ini
+[ v3_ext ]
+crlDistributionPoints=URI:http://ca.example.com/crl.pem
+```
+
+## Public (unauthenticated) CRL endpoint
+
+`GET /public/certificates/{issuer_id}/crl` is intended for CRL Distribution Point
+(CDP) URIs embedded in certificates. Any relying party — browser, TLS stack, OCSP
+client — can fetch the current CRL without credentials, as required by
+[RFC 5280 §3](https://www.rfc-editor.org/rfc/rfc5280#section-3).
+
+The response includes:
+
+- `Content-Type: application/pkix-crl`
+- `Last-Modified` (RFC 7231 IMF-fixdate)
+- `Cache-Control: public, max-age=N` where N is derived from `nextUpdate − 60 s`
+
+The endpoint returns **404** only if the CRL has never been generated and no CRL
+is stored in the database.
+
+!!! note "Cold-start behaviour"
+    Generated CRLs are persisted in the KMS database (`crls` table) and reloaded
+    on server restart, so the public endpoint continues to serve the last signed CRL
+    without requiring a manual `generate-crl` call after each restart.
+
+## Authority Information Access (AIA)
+
+The AIA extension (`authorityInfoAccess`, OID `1.3.6.1.5.5.7.1.1`) can be added
+via the extension config file to point relying parties to an OCSP responder or to
+the CA issuer certificate:
+
+```ini
+[ v3_ext ]
+authorityInfoAccess=OCSP;URI:http://ocsp.example.com/,caIssuers;URI:http://ca.example.com/ca.crt
+```
+
+!!! note "OCSP responder not built in"
+    The KMS does not embed an OCSP responder. The AIA extension can reference an
+    external OCSP service. CRL-based revocation is fully supported; OCSP is a
+    future enhancement.
+
+## No Revocation Available (`id-ce-noRevAvail`, RFC 9608)
+
+For **self-signed certificates** (no issuer key provided) that do not carry a CRL
+distribution point, the KMS automatically adds the `id-ce-noRevAvail` extension
+(OID `2.5.29.56`, RFC 9608 §2). This signals to relying parties that no
+revocation information is available for this certificate, and that they MUST NOT
+reject it for lack of a CRL or OCSP response.
+
+This behaviour applies to **all algorithms** (RSA, EC, ML-DSA, SLH-DSA, …).
+
+When validating a chain, the KMS skips CRL fetching for any certificate that
+carries this extension.

-### No Revocation Available (`id-ce-noRevAvail`, RFC 9608)
-
-For **self-signed certificates** (no issuer key provided) that do not carry a
-CRL distribution point, the KMS automatically adds the
-`id-ce-noRevAvail` extension (OID 2.5.29.56, RFC 9608 §2). This signals
-to relying parties that no revocation information is available for this
-certificate, and that they should not reject it for lack of a CRL or OCSP
-response.
-
-This behavior applies to **all algorithms** (RSA, EC, ML-DSA, SLH-DSA, …),
-not only PQC.
-
-When validating a chain, the KMS skips CRL fetching for any certificate that
-carries this extension.
+See **[Revocation & CRL Distribution](pki-revocation.md)** for CRL generation,
+automatic CDP injection, the public distribution endpoint, and the `noRevAvail`
+extension.

Subject: [PATCH 151/181] fix(test_kms_server): update config paths to match
 test_data feature/split_key layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The test_data submodule (feature/split_key branch) reorganized
configs/server/ into subdirectories:
- crypto_officer_users.toml  → rbac/
- non_revocable.toml         → test/
- hsm.toml                   → hsm/hsm_test.toml
- pqc_tls.toml               → tls/

Update all four path references in test_server.rs accordingly.
Fixes all non-fips CI failures.

Subject: [PATCH 152/181] feat: implement auto CRL refresh and persist CRLs in
 DB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- fix(crl): use find_all in find_revoked_certificates so CRL includes
  certs from all users, not just those accessible to the requesting user
- feat(crl): add CO guard at generate_crl entry; audit-log CO bypass
- feat(crl): add KMS::find_active_co() helper (first active CO or None)
- feat(crl): auto-regenerate issuer CRL on certificate revocation when
  kms_public_url is set; uses find_active_co for signer identity;
  errors are warn-logged and never fail the Revoke operation
- feat(db): add crls table (SQLite/PgSQL/MySQL/Redis) with upsert_crl
  and get_crl; table created at server boot alongside all other tables
- feat(crl): persist signed CRL to DB after every generate_crl call
- feat(crl): get_cached_crl loads from DB on cold start (no 404 after
  server restart); public CDP endpoint immediately available
- test(crl): add test_crl_contains_certs_from_all_users — regression
  guard for find_all fix: 3 certs owned by 2 users, CRL must have 3
  entries; reverts to 1 without fix
- fix(lychee): exclude crate/ from link checks to avoid false-positive
  parse errors on multi-host PostgreSQL connection strings in comments
- docs(pki): sync pki.md with auto-CDP injection, public CDP endpoint,
  CO requirement, auto-regen on revoke, DB persistence, kms_public_url
- docs(revoke): remove stale 'revocation reason not maintained' sentence
- docs(tables): add crls table (count 5->6, schema, ERD, Redis note)
- docs(log-reference): add new auto-CRL warn/info/audit log entries

Subject: [PATCH 154/181] fix(test): use temp file in sr_crl_10 instead of
 test_data submodule

The test relied on test_data/certificates/openssl/prime256v1.crl which is
not available in all CI environments (submodule not checked out for some
jobs). Replace with a self-contained tempfile::NamedTempFile write so the
test is hermetic on every runner. Rephrase inline comment to avoid lychee
false-positive on file:// placeholder text.

Subject: [PATCH 156/181] fix: GHSA-rwc8-xwm6-52xc

SSRF via attacker-controlled CRL Distribution Points in KMIP Validate/Import (COSMIAN-2026-020).

- Add validate_crl_url() in crate/server/src/core/certificate/mod.rs:
  blocks private/loopback/link-local IPs and internal hostnames before
  any network I/O; allows HTTP and HTTPS (RFC 5280 CDPs are typically HTTP).
- Rewrite get_crl_bytes() in crate/server/src/core/operations/validate.rs:
  - Call validate_crl_url() before every HTTP(S) fetch
  - Exempt kms_public_url prefix (server's own CRL endpoint is trusted)
  - Add reqwest::redirect::Policy::none() (no redirect following)
  - Add 30-second request timeout
  - Cap response body at 10 MiB (CRL_MAX_RESPONSE_BYTES)
  - Reject bare filesystem paths and file:// URIs in production
  - Allow file:// in #[cfg(any(test, feature = "insecure"))] for test fixtures
  - Use ? on .send() so network failures stay ClientConnectionError (soft-fail)
- Add kms_public_url param to verify_crls() and get_crl_bytes(); pass from
  both validate_operation() and import_operation() via kms.params
- Add 10 regression tests SR-CRL-01 through SR-CRL-10 covering all vectors
- Add COSMIAN-2026-020 entry to SECURITY.md
- Exclude RFC-1918/link-local test URLs from lychee link checker

+# Two-phase testing strategy:
+#
+# Phase 1 — Policy tests (OPA only, no KMS):
+#   Queries OPA /v1/data/kms/allow directly with crafted inputs.
+#   Covers all roles × operations × domain scenarios without a running KMS.
+#
+# Phase 2 — Integration tests (KMS + OPA):
+#   Starts KMS with --features insecure (accepts unsigned JWTs) and --opa-mode enforcing.
+#   Verifies that the full HTTP → KMS → OPA → allow/deny stack works correctly.
+#
+#   IMPORTANT: For KMIP operations, HTTP status codes do NOT reflect OPA decisions:
+#   - Missing/invalid JWT         → HTTP 401  (JWT auth middleware, before KMS handler)
+#   - OPA allows the operation    → HTTP 200 + KMIP ResultStatus "Success"
+#   - OPA denies the operation    → HTTP 200 + KMIP ResultStatus "OperationFailed"
+#   This is because KMIP errors are always wrapped in HTTP 200 per the KMIP protocol.

+# Features
+
+- Add OPA (Open Policy Agent) RBAC middleware integration with three modes: disabled, exclusive, enforcing
+- Add `--opa-url` and `--opa-mode` CLI flags (env vars `KMS_OPA_URL`, `KMS_OPA_MODE`) to configure the OPA sidecar
+- Add `domain` column to the objects table across all database backends (SQLite, PostgreSQL, MySQL, Redis-findex) for domain-scoped access control
+- Add `OpaClient` HTTP client with fail-closed design (deny on any transport/parse error)
+- Wire OPA authorization into `user_has_permission()` with mode-dependent behavior:
+    - Exclusive: OPA is the sole decision maker
+    - Enforcing: both OPA and legacy KMS permission logic must allow
+- Add `build_opa_input()` helper that constructs the OPA input document from request context
+- Add `kms.rego` Rego policy supporting role-based domain-scoped access control
+- Extract JWT `roles` and `as_domain` claims into `AuthenticatedUser` for OPA context
+- Add per-request `OpaUserContext` thread-local to propagate roles/domain without threading through all function signatures
+
+## Documentation
+
+- Restructure `documentation/docs/configuration/authorization/` into 4 pages:
+    - `index.md`: overview, mode table, architecture diagram, role model, domain model, JWT claims, OPA input document, ceremony note, config reference
+    - `mode1.md`: native KMS permissions (ownership, grants, HSM, privileged users) with sequence and flowchart diagrams
+    - `mode2.md`: exclusive OPA mode with sequence diagram, Rego evaluation flowchart, fail-closed diagram, debug endpoint
+    - `mode3.md`: enforcing dual-gate mode with sequence diagram, compound decision flowchart, interaction scenarios table
+- Remove `is_super_admin` from OPA input document — ceremony super-admin is fully decoupled from OPA (native KMS gate only)
+- Remove `is_super_admin` allow rule and `super_admin_ceremony` reason from `kms.rego`
+- Update `OPA-middleware.md` SA3 section to reflect full decoupling
+- Update `documentation/mkdocs.yml` navigation
+
+## Refactor
+
+- Add `domain: String` field to `ObjectWithMetadata` struct
+- Extend `ObjectsStore::create()` trait with `domain: &str` parameter
+- Add schema migration for existing databases (ALTER TABLE ADD COLUMN domain)
+- Add `roles: Vec` and `domain: Option` fields to `AuthenticatedUser`
+- `UserClaim` (JWT deserialization) now includes `roles` and `domain` (alias `as_domain`) fields
+
+## Testing
+
+- Add 5 OPA integration test vectors under `test_data/vectors/opa/` covering mode 1 (disabled), mode 2 (exclusive), and mode 3 (enforcing), with both allowed and denied paths
+- Add `setup_auth_server_for_opa()` helper that provisions the auth server (KMS_AUTH_SERVER_URL) with a `kms-opa-test` realm and `kms-opa-officer` user (CryptoOfficer role) via reqwest REST calls
+- Add `get_or_init_opa_allowed_server()` and `get_or_init_opa_denied_server()` OnceCell helpers that start KMS servers patched with OPA config; tests skip gracefully when `KMS_OPA_URL` or `KMS_AUTH_SERVER_URL` env vars are absent
+- Add `argon2` and `sha2` dev-dependencies to `test_kms_server` for computing Argon2id password hashes matching the auth server's formula
+- Add `json` and `cookies` features to the `reqwest` dev-dependency for auth server REST calls
+- Add 2 new OPA negative test vectors under `test_data/vectors/opa/`:
+    - `mode_exclusive_user_role_denied`: `User`-role JWT (non-owner) attempts `Get` on an officer's key → denied because `Get ∉ user_ops` in `kms.rego`
+    - `mode_exclusive_wrong_domain`: `CryptoOfficer` JWT in domain `kms-opa-other` attempts `Get` on a key created in domain `kms-opa-test` → denied because `same_domain` helper fails
+- Extend `IdentityConfig` with `access_token_env: Option` to support JWT-based multi-identity test vectors (in addition to existing mTLS `client_cert`/`client_key`)
+- Extend `build_identity_clients` to build JWT identity clients via `access_token_env` (reads named env var for the Bearer token; clears mTLS settings)
+- Extend `setup_auth_server_for_opa` to provision 3 users: `kms-opa-officer` (CryptoOfficer, kms-opa-test), `kms-opa-user` (User, kms-opa-test), `kms-opa-other-officer` (CryptoOfficer, kms-opa-other); store extra JWTs in `KMS_TEST_OPA_USER_ROLE_JWT` / `KMS_TEST_OPA_OTHER_DOMAIN_JWT`
+- Restructure `setup_auth_server_for_opa` to use separate admin (`cookie_store=true`) and login (cookieless) clients, preventing admin session cookie from being overwritten by user logins
+- Add 3 more OPA test vectors (`mode_exclusive_auditor_destroy_denied`, `mode_exclusive_auditor_get_attributes_allowed`, `mode_exclusive_domain_admin_wrong_domain`) with JWT-based Auditor and DomainAdmin identities; now 11 OPA vectors total, all passing
+- Extend `setup_auth_server_for_opa` to provision 5 users with per-user `domain` field: `kms-opa-officer` (CryptoOfficer, kms-opa-test), `kms-opa-user` (User, kms-opa-test), `kms-opa-auditor` (Auditor, kms-opa-test), `kms-opa-domain-admin-other` (DomainAdmin, kms-opa-other), `kms-opa-other-officer` (CryptoOfficer, kms-opa-other); store JWTs in `KMS_TEST_OPA_AUDITOR_JWT`, `KMS_TEST_OPA_DOMAIN_ADMIN_OTHER_JWT`
+
+## Bug Fixes
+
+- `UserClaim` JWT deserialization: add `#[serde(default)]` to `aud` field so JWTs without an `aud` claim (e.g. from Cosmian auth server) are accepted instead of failing with "missing field `aud`"
+- JWT middleware: fall back to `sub` claim when `email` is absent, enabling compatibility with Cosmian auth server JWTs that use `sub` for the username
+- OPA denied test servers: merge `exclusive_denied` and `enforcing_denied` into a single shared `ONCE_VECTOR_OPA_DENIED` singleton to avoid concurrent macOS Keychain PKCS#12 loading failures (`OSStatus -26276`) when both servers start in parallel
+- OPA denied test servers: set opa-mode-specific `sqlite_path`, `root_data_path`, and `socket_server_start = false` to prevent port/file conflicts between concurrent cert-auth test servers
+- Auth server provisioning: use `drop()` instead of `let _ =` on HTTP responses to avoid `let_underscore_drop` Clippy lint
+- Auth server provisioning: treat all HTTP errors on idempotent steps (realm/admin/userpass creation) as non-fatal, since re-running against a live in-memory auth server returns `500 UNIQUE constraint` instead of `409`
+- Fix `create.rs` to stamp the created object with the creator's domain (from OPA user context) instead of hardcoded `""`, enabling non-owner domain-scoped role checks (Auditor, DomainAdmin) to work correctly
+- Fix `kms.rego` operation names: all role-based op sets (`crypto_officer_ops`, `auditor_ops`, `user_ops`) now use lowercase snake_case names matching `KmipOperation::Display` output (e.g. `"get_attributes"` not `"GetAttributes"`)
+- Fix `mode_exclusive_auditor_destroy_denied` manifest: wrong `assert_error_reason` was `Object_Not_Found`; Destroy uses a count guard returning `Item_Not_Found` when no object passes permission check
+- Fix auth server provisioning: set `domain` field on each userpass record to the realm ID so the JWT `as_domain` claim is emitted and OPA `same_domain` checks work correctly
+- Fix `enforce_create_permission`: honor `crypto_officer.users` and `default_username` for the `Create` right even when OPA is active, so KMS-native CryptoOfficers (e.g. split-key ceremony participants) can still create keys; OPA remains the authoritative gatekeeper for all other users
+- OPA test provisioning: send plaintext passwords to the auth server's `create_userpass` endpoint (the server now computes the Argon2id hash itself) and drop the obsolete `argon2`/`sha2` dev-dependencies

+# OPA RBAC Middleware — Context and Implementation Plan
+
+## Context
+
+### What is being built
+
+An OPA (Open Policy Agent) authorization layer for Cosmian KMS that evaluates RBAC rules
+before (or alongside) the existing KMS permission system.
+
+KMS runs the OPA server as a sidecar. On every KMIP operation, KMS calls
+`POST /v1/data/kms/allow` with a JSON input document. OPA evaluates `kms.rego` and returns
+`{"result": true|false}`.
+
+Three modes:
+
+| Mode | Name | Semantics |
+|------|------|-----------|
+| 1 | `Disabled` | OPA is not called; existing KMS permission system runs unchanged |
+| 2 | `Exclusive` | Only OPA decides; KMS permission system is skipped |
+| 3 | `Enforcing` | OPA runs first; if true, KMS permission system also runs; both must allow |
+
+Fail-closed: if OPA is configured but unreachable, the request is denied.
+
+---
+
+### Role model
+
+Five roles (defined in the authentication server's realm configuration, embedded in JWT):
+
+| Role | Access |
+|------|--------|
+| `SuperAdmin` | Unrestricted, cross-domain |
+| `DomainAdmin` | Full control within their own domain |
+| `CryptoOfficer` | Key lifecycle operations within their domain (FIPS 140-3 §7.4) |
+| `Auditor` | Read-only metadata within their domain (NIST SP 800-53 AU-9) |
+| `User` | Crypto-use only within their domain (encrypt/decrypt/sign/verify) |
+
+Roles are stored per-user per-realm in the authentication server's `userpass` table.
+Multiple roles per user are allowed (RBAC union semantics in OPA — existential over the array).
+An object owner always has full access regardless of role.
+
+---
+
+### Architecture: A3-i (JWT carries `roles` claim)
+
+```text
+User authenticates → Auth Server issues JWT
+  JWT contains:
+    "roles": ["CryptoOfficer"]           ← RFC 9068 §2.2.3.1, RFC 7643 §4.1.2
+    "as_domain": "acme.com"              ← private claim (RFC 7519 §4.3)
+
+KMS receives request with JWT
+  KMS extracts:
+    sub       → input.user
+    as_domain → input.user_domain
+    roles     → input.roles[]
+
+KMS calls OPA:
+  POST /v1/data/kms/allow
+  {
+    "input": {
+      "user":          "alice@acme.com",
+      "user_domain":   "acme.com",
+      "roles":         ["CryptoOfficer"],
+      "operation":     "Create",
+      "object_uid":    "*",
+      "object_domain": "acme.com",
+      "is_owner":      false
+    }
+  }
+
+OPA evaluates kms.rego → {"result": true}
+
+KMS applies mode logic:
+  Exclusive:  allow = opa_result
+  Enforcing:  allow = opa_result AND kms_result
+```
+
+Non-JWT auth (mTLS, API token): KMS sends `"roles": []` → all role-based rules are false → fail-closed.
+
+---
+
+### Domain model
+
+`user_domain` comes from the `as_domain` JWT private claim — not inferred from the `sub` string.
+This decouples username format from domain assignment entirely.
+
+`object_domain` is stamped at object creation time from the creator's `user_domain` and stored
+as a new `domain` column on the `objects` table. It is immutable after creation.
+
+For object-less operations (e.g. `Create`): `object_domain = user_domain` at permission-check time.
+
+Existing objects (before this feature) get `domain = ''`, which only `SuperAdmin` can access
+via domain-scoped roles (the `same_domain` rule fails; owner rule still works).

+### KMIP role taxonomy (verified against local spec files)
+
+> **Verified against `kmip/v2.1/kmip-spec-v2.1-os.html` and `kmip/v3.0/kmip-spec-v3.0-csd01.html`.**
+
+KMIP defines **two** concepts named "role" — neither of which is a user authorization role:
+
+#### 1. Endpoint Role (KMIP 2.1 §11.19, Table 451–452)
+
+Used exclusively by the `Set Endpoint Role` operation (§6.1.54 / §6.2.5), which
+swaps client/server roles on a bidirectional communication channel.
+
+| Value | Description |
+|-------|-------------|
+| `Client` | The endpoint that sends requests and receives responses |
+| `Server` | The endpoint that receives requests and sends responses |
+
+**Not a user authorization concept.** Only relevant for KMIP bidirectional channel setup.
+
+#### 2. Key Role Type (KMIP 2.1 §11.26, Table 462)
+
+A cryptographic key classification attribute — describes the *purpose* of a key,
+not who may use it. Values (KMIP 2.1):
+
+| Name | Value | Meaning |
+|------|-------|---------|
+| BDK | 0x00000001 | Base Derivation Key |
+| CVK | 0x00000002 | Card Verification Key |
+| DEK | 0x00000003 | Data Encryption Key |
+| MKAC | 0x00000004 | Master Key — AC |
+| MKSMC | 0x00000005 | Master Key — SMC |
+| MKSMI | 0x00000006 | Master Key — SMI |
+| MKDAC | 0x00000007 | Master Key — DAC |
+| MKDN | 0x00000008 | Master Key — DN |
+| MKCP | 0x00000009 | Master Key — CP |
+| MKOTH | 0x0000000A | Master Key — Other |
+| KEK | 0x0000000B | Key Encryption Key |
+| MAC16609 | … | MAC key (ISO 16609) |
+
+**Not a user authorization concept.** This is a key metadata attribute, not an
+identity/permission claim.
+
+#### Conclusion: KMIP does NOT define user authorization roles
+
+Neither KMIP 2.1 nor KMIP 3.0 defines concepts such as Administrator, Auditor,
+or CryptoOfficer as user authorization roles. The terms "CryptoOfficer" and
+"Auditor" do not appear anywhere in either specification outside of OASIS
+administrative boilerplate.
+
+The role model in this project (`SuperAdmin`, `DomainAdmin`, `CryptoOfficer`,
+`Auditor`, `User`) is **implementation-defined**, sourced from:
+
+- **FIPS 140-3 §7.4** — mandates a "Crypto Officer" role and a "User" role for
+  cryptographic module access control. Names and semantics are normative.
+- **NIST SP 800-57 Part 2 §4.3** — defines "Key Management Officer", "Audit and
+  Compliance Officer", and "Key User" as organizational roles in a key management
+  infrastructure.
+- **ANSI/INCITS 359-2004 §4.2** — RBAC model for hierarchical and constrained
+  role structures (basis for DomainAdmin hierarchy).
+
+These are the correct normative citations for the role names used in `kms.rego`.
+
+---
+
+## Design decisions
+
+| # | Question | Decision | Rationale |
+|---|----------|----------|-----------|
+| S1 | Role storage in auth DB | JSON TEXT column on `userpass` | Minimal schema change; roles are only read at login, never filtered in SQL |
+| R1 | JWT `roles` wire shape | `Vec` — plain string array | RFC 9068 provides no vocabulary; string array is the common implementation |

+
+## Ceremony super-admin and OPA — separation of concerns
+
+The KMS ceremony super-admin (Shamir split-key) and OPA RBAC are **fully independent**:
+
+- `is_super_admin` is **not** included in the OPA input document.
+- OPA has no visibility into the ceremony state.
+- In Mode 1 (Disabled): ceremony super-admin operates as before (early return in native KMS check).
+- In Mode 2 (Exclusive): ceremony has no effect — OPA is the sole decision maker.
+- In Mode 3 (Enforcing): ceremony super-admin takes effect inside Gate 2 (native KMS), only after OPA has already allowed.
+
+The JWT `SuperAdmin` role (assigned by auth admin) and the ceremony super-admin (Shamir activation) are distinct concepts with different trust anchors and different enforcement paths.
+
+---
+
+## Implementation plan
+
+### Phase 1 — Auth server: data model
+
+**Step 1** — `client/src/models/client_claims.rs`
+
+Add `AuthorizationClaims` (RFC 9068 §2.2.3.1 public claims, RFC 7643 §4.1.2):
+
+```rust
+/// RFC 9068 §2.2.3.1 — Authorization claims (IANA-registered via RFC 7643 §4.1.2).
+#[derive(Debug, Clone, Serialize, Deserialize, Default)]
+pub struct AuthorizationClaims {
+    /// `roles` — roles assigned to the subject.
+    /// RFC 7643 §4.1.2; registered in IANA JWT Claims registry by RFC 9068 §7.2.1.1.
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub roles: Option>,
+}
+```
+
+Add `domain` to `AuthPrivateClaims`:
+
+```rust
+/// Domain the subject belongs to, used for domain-scoped RBAC.
+/// Private claim (RFC 7519 §4.3) — not an IANA-registered name.
+#[serde(rename = "as_domain", skip_serializing_if = "Option::is_none")]
+pub domain: Option,
+```
+
+Add to `ClientClaims`:
+
+```rust
+/// RFC 9068 §2.2.3.1 — authorization attributes (roles, groups, entitlements).
+#[serde(flatten)]
+pub authorization: AuthorizationClaims,
+```
+
+**Step 2** — `client/src/models/base.rs`
+
+Add to `UserPass`:
+
+```rust
+/// Roles assigned to this user in this realm.
+/// Serialised as JSON array in the DB column `roles`.
+pub roles: Vec,
+
+/// Domain the user belongs to (e.g. "acme.com").
+/// Emitted as the `as_domain` JWT private claim.
+pub domain: Option,
+```
+
+---
+
+### Phase 2 — Auth server: database layer (all 3 backends)
+
+**Step 3** — Schema change in each backend:
+
+```sql
+-- Add to CREATE TABLE userpass:
+roles  TEXT NOT NULL DEFAULT '[]',
+domain TEXT
+```
+
+Migration queries (run at startup, check-then-ALTER pattern):
+
+```sql
+-- add-column-roles
+ALTER TABLE userpass ADD COLUMN roles TEXT NOT NULL DEFAULT '[]';
+-- add-column-domain
+ALTER TABLE userpass ADD COLUMN domain TEXT;
+```
+
+**Step 4** — CRUD update in all 3 backends:
+
+- `create_userpass`: INSERT includes `roles` (JSON-serialised), `domain`
+- `get_userpass`: SELECT reads `roles` (deserialise → `Vec`), `domain`
+- `update_userpass`: UPDATE includes both
+- `list_*`: SELECT includes both
+
+Serialisation:
+
+- write: `serde_json::to_string(&userpass.roles)?`
+- read: `serde_json::from_str::>(&row_roles).unwrap_or_default()`
+
+---
+
+### Phase 3 — Auth server: token issuance
+
+**Step 5** — `server/src/session/jwt.rs`
+
+New signature:
+
+```rust
+pub fn issue_token(
+    subject: &str,
+    auth_scheme: AuthScheme,
+    realm_id: &str,
+    public_key_pem: Option,
+    roles: Vec,          // NEW — from UserPass.roles
+    domain: Option,      // NEW — from UserPass.domain
+    algorithm: Algorithm,
+    encoding_key: EncodingKey,
+    expiration_seconds: i64,
+) -> Result
+```
+
+Inside: `claims.authorization.roles = Some(roles)` and `claims.private.domain = domain`.
+
+**Step 6** — `server/src/server/endpoints/client_endpoints.rs`
+
+In `login()`, after TOTP check, before `issue_token()`:
+
+```rust
+let userpass = database
+    .get_userpass(&realm.id, &authenticated_client.username)
+    .await?;
+let (roles, domain) = userpass
+    .map(|u| (u.roles, u.domain))
+    .unwrap_or_default();
+// Non-userpass schemes (mTLS) return None → roles=[], domain=None → N1 satisfied
+```
+
+---
+
+### Phase 4 — Auth server: API surface
+
+**Step 7** — `server/src/server/endpoints/realms_endpoints.rs`
+
+No handler logic change needed — `roles` and `domain` are carried by the `UserPass` struct
+which is already deserialized from the request body and passed to `database.create_userpass()`.
+
+**Step 8** — `server/documentation/openapi.yaml`
+
+Add to `UserPass` schema:
+
+```yaml
+roles:
+  type: array
+  items:
+    type: string
+  description: "Roles assigned to this user (RFC 9068 §2.2.3.1)"
+  example: ["CryptoOfficer"]
+domain:
+  type: string
+  nullable: true
+  description: "Domain the user belongs to, emitted as as_domain JWT claim"
+  example: "acme.com"
+```
+
+---
+
+### Phase 5 — KMS: Rego policy update
+
+**Step 9** — `test_data/opa/kms.rego`
+
+- `input.role` → removed entirely
+- All role checks: `input.role == "X"` → `input.roles[_] == "X"` (Rego existential)
+- `reason := "no_role"`: check `count(input.roles) == 0; not input.is_owner`
+- Header: document `input.roles` as array from JWT, `input.user_domain` from `as_domain`
+
+---
+
+### Phase 6 — KMS: object domain
+
+**Step 10** — `crate/interfaces/src/stores/object_with_metadata.rs`
+
+```rust
+pub struct ObjectWithMetadata {
+    id: String,
+    object: Object,
+    owner: String,
+    state: State,
+    attributes: Attributes,
+    domain: String,   // NEW — stamped at creation, empty string for legacy objects
+}
+```
+
+Add `domain()` getter; update `new()` to require `domain: String`; update `Display`.
+
+**Step 11** — SQL schema (`query.sql`, `query_mysql.sql`)
+
+```sql
+-- In CREATE TABLE objects:
+domain VARCHAR(255) NOT NULL DEFAULT '',
+```
+
+Migration:
+
+```sql
+-- add-column-domain
+ALTER TABLE objects ADD COLUMN domain VARCHAR(255) NOT NULL DEFAULT '';
+```
+
+**Step 12** — DB backend CRUD (sqlite.rs, pgsql.rs, mysql.rs)
+
+- `ObjectsStore::create()` trait: add `domain: &str` parameter
+- INSERT: include `domain`
+- SELECT: include `domain`, populate `ObjectWithMetadata::domain`
+
+---
+
+### Phase 7 — KMS: OPA input construction
+
+**Step 13** — `OpaInput` struct (new module, e.g. `crate/server/src/core/opa/input.rs`):
+
+```rust
+#[derive(Serialize)]
+pub struct OpaInput {
+    pub user: String,
+    pub user_domain: String,    // from claims.private.domain (as_domain), or ""
+    pub roles: Vec,     // from claims.authorization.roles, or []
+    pub is_super_admin: bool,   // SA3: from kms.is_super_admin(user)
+    pub operation: String,
+    pub object_uid: String,
+    pub object_domain: String,  // from ObjectWithMetadata.domain
+    pub is_owner: bool,
+}
+```
+
+**Step 14** — `build_input()` in the permission layer:
+
+- JWT present: extract `claims.authorization.roles` → `Vec`, `claims.private.domain` → `String`
+- JWT absent (mTLS/API-token): `roles = vec![]`, `user_domain = ""`
+- Object-less ops (Create, Locate, etc.): `object_domain = user_domain`
+- Object-bearing ops: `object_domain = owm.domain()`
+- SA3: call `kms.is_super_admin(user).await?` → `is_super_admin: bool`
+
+**Step 15** — Object creation path:
+
+When `Create` is dispatched, `user_domain` is available from the request context.
+Pass it into `database.create(uid, owner, object, attributes, tags, user_domain)`.
+
+---
+
+### Phase 8 — KMS: OPA client + configuration
+
+**Step 16** — New types:
+
+```rust
+pub enum OpaMode { Disabled, Exclusive, Enforcing }
+
+pub struct OpaParams {
+    pub url: String,    // e.g. "http://localhost:8181"
+    pub mode: OpaMode,
+}
+```
+
+**Step 17** — `OpaClient` (reqwest, fail-closed):
+
+```rust
+impl OpaClient {
+    /// Returns Ok(true) if OPA allows, Ok(false) if denied, Err if unreachable.
+    /// Callers treat Err as deny (fail-closed).
+    pub async fn query(&self, input: &OpaInput) -> Result;
+}
+```
+
+**Step 18** — Extend `ServerParams` and KMS struct:
+
+- `server_params.rs`: `pub opa_params: Option`
+- `kms/mod.rs`: `pub(crate) opa_client: Option>`
+
+**Step 19** — `clap_config.rs`:
+
+```text
+--opa-url      OPA sidecar base URL (enables OPA integration)
+--opa-mode    "exclusive" or "enforcing" [default: "enforcing"]
+```
+
+**Step 20** — `crate/server/src/core/retrieve_object_utils.rs`
+
+In `user_has_permission()` — SA3 integration:
+
+```rust
+// Mode 0 (Disabled) — existing flow unchanged:
+//   line 225: if kms.is_super_admin(user).await? { return Ok(true); }
+//   ... normal HSM + DB checks ...
+
+// Mode 2/3 (Exclusive/Enforcing) — OPA is the sole gate:
+if kms.opa_client.is_some() {
+    // Skip the is_super_admin() early return — SA3 feeds it into OPA input instead
+    let input = build_input(kms, user, owm, operation_type).await?;
+    //   ↑ build_input calls kms.is_super_admin(user) → sets input.is_super_admin
+    let opa_ok = kms.opa_client.as_ref().unwrap()
+        .query(&input).await.unwrap_or(false); // fail-closed
+    match kms.params.opa_mode {
+        OpaMode::Exclusive => return Ok(opa_ok),
+        OpaMode::Enforcing => {
+            if !opa_ok { return Ok(false) }
+            // fall through to HSM admin + DB grant checks
+        }
+        OpaMode::Disabled => unreachable!(),
+    }
+} else {
+    // Mode 0 — existing super-admin bypass + normal logic
+    if kms.is_super_admin(user).await? {
+        warn!("SUPER_ADMIN_ACCESS: ...");
+        return Ok(true);
+    }
+}
+// ... HSM admin check, DB permission check ...
+```
+

+
+## Scope exclusions
+
+- **Admin realm**: the `_` admin realm does not participate in KMS RBAC. Admins manage realms/users; they are not KMS crypto operators.
+- **Redis-findex backend**: domain column follows the same OB1 pattern but is tracked as a separate task (Redis store has a different object representation).
+- **Wizard / TOML templates**: `--opa-url` / `--opa-mode` are CLI flags only in this phase; wizard integration is deferred.
+- **WASM bindings**: client-side only, no OPA involvement.
+- **`privileged_users`**: this config field is not consulted in OPA modes 2 or 3. SuperAdmin role in OPA is the equivalent.

+# ADR-0003: RBAC Authorization Model with OPA Sidecar
+
+| Field       | Value                                |
+|-------------|--------------------------------------|
+| **Status**  | Accepted                             |
+| **Date**    | 2026-06-24                           |

+| **PR**      | [#998](https://github.com/Cosmian/kms/pull/998) |
+| **Authors** | Cosmian Engineering                  |
+
+---
+
+## 1. Context
+
+### 1.1 Prior state
+
+The Cosmian KMS has always enforced a per-object, per-user, per-operation grant
+table stored in the KMS database (the *legacy permission layer*).  Every managed
+object carries an owner, and other users may be granted specific KMIP operations
+via explicit `AddAccess` / `RevokeAccess` calls.  The owner always has full
+access to their own objects.
+
+This model has two structural gaps for enterprise deployments:
+
+1. **No role-based abstractions.** Access is granted object-by-object.
+   There is no concept of a *role* that covers many objects at once.
+2. **No central policy enforcement.** Policy lives only in the KMS database;
+   auditors, SOC teams, and governance tooling cannot inspect or override it
+   without calling KMS-specific APIs.
+
+### 1.2 Requirements driving this ADR
+
+| Requirement | Detail |
+|---|---|
+| **Role-based decisions** | Support CryptoOfficer, Auditor, User, DomainAdmin, SuperAdmin roles out of the box, with role semantics expressible in a human-readable policy file. |
+| **Dynamic roles** | Role names and the operations they permit must be changeable at runtime without restarting the KMS server.  Role vocabulary must **not** be hardcoded in the KMS binary or configuration file. |
+| **Domain isolation** | Keys belong to a *domain* (a tenant identifier). Most roles are constrained to their own domain; only a SuperAdmin is cross-domain. |
+| **Separation of duties** | Auditor and CryptoOfficer must be mutually constrainable — enforced in policy, not in code. |
+| **Audit trail** | Every access decision must be attributable to a policy rule, visible in OPA's structured logs. |
+| **Backward compatibility** | Operators who do not configure OPA must see no behavior change. |
+| **Fail-closed** | Any failure in the authorization path (network, parse error, OPA timeout) must result in denial, not approval. |
+
+### 1.3 Constraints
+
+- The KMS is Actix-web 4.x, async/multi-threaded Tokio runtime.
+- Roles reach the KMS as JWT claims from an external Identity Provider (IdP)
+  or Authentication Server; the KMS must not hard-code role names.
+- The KMIP 2.1 specification does **not** define user authorization roles.
+  The five roles adopted here are drawn from FIPS 140-3 §7.4, NIST SP 800-57
+  Part 2 §4.3, and ANSI/INCITS 359-2004 (RBAC standard).
+
+---
+
+## 2. Decision
+
+### 2.1 OPA as an authorization sidecar
+
+[Open Policy Agent (OPA)](https://www.openpolicyagent.org/) is deployed as a
+sidecar process alongside the KMS server.  The KMS calls OPA over its REST Data
+API (`POST /v1/data/kms/allow`) for every access-control decision.
+
+**Why a sidecar, not an embedded library?**
+
+- Policy files (`.rego`) are human-readable and version-controlled independently
+  of the Rust binary.
+- Operators can reload policy without restarting the KMS.
+- OPA's decision log (`--log-level=info`) produces a structured audit trail
+  independent of KMS logs.
+- A sidecar allows OPA to hold its own data documents (role assignments, domain
+  maps) pushed via the OPA Data API — the KMS never needs to store role data.
+
+### 2.2 Three evaluation modes
+
+Three modes are supported, selected via `--opa-url` (enables OPA) and
+`--opa-mode`:
+
+| Mode | `KMS_OPA_MODE` | Behavior |
+|---|---|---|
+| **Disabled** | *(absent `--opa-url`)* | OPA is not called; only legacy DB grants decide. |
+| **Exclusive** | `exclusive` | OPA is the sole decision maker; the legacy DB grant table is not consulted.  Suitable for greenfield deployments that manage all access through policy. |
+| **Enforcing** | `enforcing` *(default)* | OPA runs first.  If OPA denies → deny immediately.  If OPA allows → the legacy DB grant check also runs for operations on existing objects (belt-and-suspenders).  For object-creation operations (`Create`, `CreateKeyPair`, `Import`, `Register`) OPA's approval is sufficient because no DB grant exists yet. |
+
+`Enforcing` is the recommended production mode: it layeres OPA policy on top of
+the existing fine-grained grant model without discarding it.
+
+### 2.3 Input document
+
+The KMS sends the following JSON document to OPA with every evaluation request:
+
+```json
+{
+  "input": {
+    "user":         "alice@acme.com",
+    "user_domain":  "acme",
+    "roles":        ["CryptoOfficer"],
+    "operation":    "Create",
+    "object_uid":   "*",
+    "object_domain": "acme",
+    "is_owner":     false
+  }
+}
+```
+
+| Field | Source | Notes |
+|---|---|---|
+| `user` | JWT `sub`, TLS CN, or API-token ID | Authenticated identity; never forged. |
+| `user_domain` | JWT `as_domain` private claim | Empty for non-JWT authentication. |
+| `roles` | JWT `roles` claim (RFC 9068 array) | **Never set by KMS config.** Empty for non-JWT auth → fail-closed. |
+| `operation` | `KmipOperation::to_string()` | Lowercase snake_case KMIP operation name (e.g. `"create"`, `"decrypt"`). |
+| `object_uid` | Target object UID | `"*"` for object-less operations. |
+| `object_domain` | Owner's domain stored with the object | Empty / equals `user_domain` for object-less operations. |
+| `is_owner` | `user == object.owner()` | Owners always receive access regardless of role. |
+
+**Key invariant**: The KMS is role-vocabulary-agnostic.  It forwards whatever
+role strings the JWT carries and lets Rego interpret them.  Adding a new role
+(e.g. `"DataEngineer"`) requires only a Rego change, not a KMS change or
+restart.
+
+### 2.4 Default Rego policy (`test_data/opa/kms.rego`)
+
+The repository ships a reference policy implementing five standard roles:
+
+| Role | Scope | Permitted operations | Normative source |
+|---|---|---|---|
+| `SuperAdmin` | Global (cross-domain) | All operations | ANSI/INCITS 359-2004 §4.2 |
+| `DomainAdmin` | Own domain | All operations | ANSI/INCITS 359-2004 §4.2 |
+| `CryptoOfficer` | Own domain | Key lifecycle: `create`, `create_key_pair`, `import`, `get`, `export`, `locate`, `get_attributes`, `set_attribute`, `modify_attribute`, `delete_attribute`, `add_attribute`, `activate`, `revoke`, `archive`, `recover`, `destroy`, `rekey`, `rekey_key_pair` | FIPS 140-3 §7.4; NIST SP 800-57 Part 2 §4.3 |
+| `Auditor` | Own domain | Read-only: `locate`, `get`, `get_attributes`, `list_access`, `query_access`, `mac_verify` | NIST SP 800-57 Part 2 §4.3; NIST SP 800-53 AU-9 |
+| `User` | Own domain | Crypto-use only: `encrypt`, `decrypt`, `sign`, `verify`, `mac`, `mac_verify`, `derive_key`, `locate`, `get_attributes` | FIPS 140-3 §7.4; PKCS#11 v3.0 |
+
+Owners always have full access to their objects, regardless of role.
+
+Operators may supply their own Rego file; the default policy is a starting
+point, not a requirement.
+
+### 2.5 Fail-closed design
+
+Any error condition in the OPA call path results in *denial*:
+
+- Network timeout (5 s hardcoded in `OpaClient`)
+- HTTP non-2xx from OPA
+- JSON parse failure
+- OPA returns `{"result": null}` (undefined policy)
+
+The decision is `Ok(false)` in all these cases.  The KMS never silently grants
+access when authorization state is unknown.
+
+### 2.6 Task-local context propagation
+
+The authenticated user's roles and domain are extracted by the auth middleware
+and stored in a `tokio::task_local!` variable (`OPA_USER_CONTEXT`).  Every
+async operation within the HTTP request's task scope reads this context when
+building the OPA input document.
+
+`thread_local!` was explicitly rejected because:
+
+- Tokio's multi-threaded scheduler migrates tasks across OS threads at every
+  `.await` point.
+- A `thread_local!` value set before an `.await` may be invisible — or belong to
+  a *different* request — when the task resumes on another thread.
+
+`tokio::task_local!` (backed by Tokio's `task_local!` macro) is scoped to the
+logical async task and survives `.await` migration safely.
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+
+- **Dynamic policy**: Operators can update role definitions and reload OPA
+  (`SIGHUP` or bundle polling) without restarting the KMS.
+- **Role-vocabulary independence**: KMS config carries no role strings.
+  Role names, operations, and domain constraints are entirely OPA's domain.
+- **Audit trail**: OPA's decision log (`/v1/data/kms/reason`) provides a
+  per-request, policy-attributed audit record independently of KMS logs.
+- **Backward compatibility**: `Disabled` mode (no `--opa-url`) leaves
+  existing deployments completely unchanged.
+- **Belt-and-suspenders in `Enforcing` mode**: Both OPA policy and the
+  legacy per-object grant table must allow an operation, reducing the risk of
+  policy misconfiguration silently widening access.
+- **Separation of duties**: The Auditor / CryptoOfficer SSD constraint is
+  expressed in the Rego policy comment as a role-assignment-time requirement;
+  enforcement is policy-level, not hard-coded.
+
+### 3.2 Negative / Trade-offs
+
+- **Extra network hop**: Every permission check incurs a local HTTP round-trip
+  to the OPA sidecar.  The 5-second timeout and fail-closed semantics mitigate
+  risk but do not eliminate latency.  OPA should be co-located on the same host
+  or within the same pod/container group.
+- **Role assignment is the authentication server's responsibility**: The KMS no longer stores or
+  manages role assignments.  Roles are issued by the authentication server as a `roles` array
+  in the JWT (RFC 9068 §2.2.3.1) and forwarded verbatim to OPA as `input.roles`.  OPA itself
+  holds no role data; the Rego policy interprets the role strings it receives from the JWT.
+  Operators who want to use OPA's Data API (`PUT /v1/data/`) to store role assignments may do
+  so, but the reference Rego policy does not require it.  This design adds an operational
+  dependency on the authentication server's user and role management.
+- **JWT-only roles**: Non-JWT authentication methods (TLS client certificates,
+  API tokens) provide no JWT `roles` claim, so `input.roles` is empty.  The Rego
+  policy can grant access to owners or on `is_owner`, but pure role-based rules
+  will fail-closed for those auth methods unless the policy explicitly handles
+  them.
+- **`Enforcing` mode complexity**: Object-creation operations bypass the legacy
+  DB grant check because no object exists yet; all other operations require both
+  OPA and a DB grant.  This asymmetry must be kept in mind when debugging access
+  denials.
+
+### 3.3 Alternatives rejected
+
+| Alternative | Reason rejected |
+|---|---|
+| Embedded OPA Go library via FFI | Significant build complexity; not idiomatic in Rust. |
+| Role enum in `kms.toml` | Hard-codes role vocabulary in KMS config; operators cannot rename roles without a KMS change and restart. |
+| Static role mapping in DB | Same problem as above; defeats the "dynamic roles" requirement. |
+| Casbin (Rust-native) | Smaller ecosystem; less operator familiarity; no native audit-log integration. |
+| OPA bundled as in-process Wasm | Experimental OPA Wasm support does not cover the Data API; cannot be updated without redeployment. |

-# Authorizing users with access rights
-
-The authorization system in the Eviden Key Management Service (KMS) operates based on two fundamental principles:
-
-1. **Ownership:** Every cryptographic object has an assigned owner. The ownership is established when an object is
-   created using any of the following KMIP operations: `Create`, `CreateKeyPair`, or `Import`. As an owner, a user holds
-   the privilege to carry out all supported KMIP operations on their objects.
-
-2. **Access rights delegation:** owners can grant access rights, allowing one or more users to perform certain KMIP
-   operations on an object. When granted such rights, a user can invoke the corresponding KMIP operation on the KMS for
-   that particular object. The owner retains the authority to withdraw these access rights at any given time.

-## Delegable KMIP operations
-
-Owners can delegate the following KMIP operations to other users via the `grant` and `revoke` endpoints (or the CLI commands `ckms access-rights grant` / `ckms access-rights revoke`):
-
-| Operation          | Description                                                     |

-| `derive_key`       | Derive a new key from an existing key                           |
-| `destroy`          | Permanently destroy an object                                   |
-| `encrypt`          | Encrypt plaintext using a managed key                           |
-| `export`           | Export an object (key material + metadata) from the KMS         |
-| `get`              | Retrieve an object — **this is a super-privilege** (see below)  |
-| `get_attributes`   | Read the KMIP attributes of an object                           |
-| `hash`             | Compute a cryptographic hash                                    |
-| `import`           | Import an external object into the KMS                          |
-| `locate`           | Search for objects matching given attributes                    |
-| `mac`              | Compute a Message Authentication Code                           |
-| `revoke`           | Revoke (deactivate) an object                                   |
-| `rekey`            | Re-key an existing symmetric key                                |
-| `sign`             | Generate a digital signature                                    |
-| `signature_verify` | Verify a digital signature                                      |
-| `validate`         | Validate a certificate chain                                    |
-| `set_attribute`    | Set (replace) an attribute on an object                         |
-| `modify_attribute` | Modify an existing attribute on an object                       |

-| `delete_attribute` | Remove an attribute from an object                              |
-
-Multiple operations can be granted or revoked in a single call. For example, using the CLI:
-
-```bash
-# Grant encrypt and decrypt to user "alice"
-ckms access-rights grant alice -i  encrypt decrypt
-
-# Revoke the get privilege from user "bob"
-ckms access-rights revoke bob -i  get
-```
-
-## The `Get` super-privilege
-
-The `Get` operation has a special role in the permission model: **it acts as a super-privilege that implies every other
-object-level operation**.
-
-When checking whether a user is authorized to perform a given operation on an object, the KMS evaluates the following
-rules in order:
-
-1. **Owner check** — if the requesting user is the owner of the object, access is always granted.
-2. **Explicit permission** — if the user has been explicitly granted the requested operation (e.g. `encrypt`), access is
-   granted.
-3. **`Get` fallback** — if the user holds the `Get` permission on the object, access is granted **regardless of the
-   specific operation requested**.
-
-In other words, granting `Get` to a user on an object is equivalent to granting that user `encrypt`, `decrypt`,
-`export`, `sign`, `derive_key`, and every other object-level operation — except lifecycle operations (`revoke`,
-`destroy`) which still require their own explicit grant.
-
-This design allows owners to share full read/use access to an object with a single permission, without individually
-enumerating every operation.
-
-!!! warning Security implication
-    Because `Get` implies all other operation-level permissions, it should be granted with care.
-    If you only need a user to encrypt data with a key, grant `encrypt` — not `get`.
-
-### Practical example
-
-| Granted permissions  | Can the user `encrypt`? | Can the user `export`? | Can the user `destroy`? |
-| -------------------- | :---------------------: | :--------------------: | :---------------------: |
-| `encrypt`            |           Yes           |           No           |           No            |
-| `get`                |           Yes           |          Yes           |           No            |
-| `encrypt`, `destroy` |           Yes           |           No           |           Yes           |
-| `get`, `destroy`     |           Yes           |          Yes           |           Yes           |
-
-!!! note
-    The `destroy` and `revoke` operations are **never** implied by `get`. They must always be granted explicitly
-    because they are irreversible lifecycle transitions.
-
-## Special handling of the `Create` permission
-
-The `Create` operation is not bound to a specific object — it controls whether a user is allowed to create _new_ objects
-in the KMS. Internally it is stored against the wildcard object identifier `*`.
-
-- When granting or revoking `create`, no object UID is required.
-- `Create` can be combined with object-level operations in the same request; the server will separate and process them
-  accordingly.
-
-## Privileged users
-
-By default, all users are allowed to create or import objects in the KMS.
-
-However, when the KMS server is configured with a list of privileged users, object creation rights are restricted as follows:
-
-- Privileged users can create or import objects and are authorized to grant or revoke object creation permissions for other users.
-- Regular users cannot create or import objects unless they have explicitly been granted permission by a privileged user.
-- Regular users cannot grant or revoke creation permissions for others.
-- Privileged users cannot revoke object creation permissions from other privileged users.
-
-### Operations gated by the privileged-user restriction
-
-Because the following operations all result in a **new cryptographic object** being created in the KMS, they are all
-subject to the same privileged-user check:
-
-| Operation       | Reason                                               |
-| --------------- | ---------------------------------------------------- |
-| `Create`        | Creates a new symmetric key or secret data object    |
-| `CreateKeyPair` | Creates a new asymmetric key pair                    |
-| `Import`        | Imports an external object into the KMS              |
-| `Register`      | Registers an externally-generated object             |
-| `Certify`       | May create a new key pair when issuing a certificate |
-| `ReKey`         | Creates a new replacement symmetric key              |
-| `ReKeyKeyPair`  | Creates a new replacement asymmetric key pair        |
-
-!!! note
-    `ReKey` and `ReKeyKeyPair` also require the caller to hold the `Rekey` permission on the existing key being
-    re-keyed. Both conditions must be satisfied: the user must be allowed to create new objects **and** be allowed
-    to rekey the specific existing key.
-
-## The wildcard user `*`
-
-!!! important "The Wildcard User: *"
-    In addition to regular users, a special user called `*` (the wildcard user) can be used to grant access rights on
-    objects to **all** users. When a permission is granted to `*`, every authenticated user benefits from that permission
-    on the targeted object. Individual per-user grants are merged with the wildcard grants when evaluating access.
-
-## HSM keys and authorization
-
-Keys stored in an HSM follow a **stricter permission model** than regular KMS keys.
-Authorization metadata (owner, grants) is still managed by the KMS, but two
-important differences apply.
-
-### Comparison with regular KMS keys
-
-| Aspect                         | KMS keys                                     | HSM keys                                           |
-| ------------------------------ | -------------------------------------------- | -------------------------------------------------- |
-| Key material stored in         | KMS database (encrypted)                     | HSM hardware                                       |
-| `Get` is a super-privilege     | Yes — implies all operations                 | **No** — each operation must be granted explicitly |
-| `Get` ↔ `Export` equivalence   | No                                           | **Yes** — holding either grants both               |
-| `Destroy` / `Revoke` delegable | Yes                                          | **No** — blocked; admin-only                       |
-| `Create`                       | Any user (or privileged users if configured) | HSM admin only                                     |
-| `Locate` visibility            | All owned / granted objects                  | Non-admins see only keys with ≥ 1 explicit grant   |
-
-### Who is an HSM admin?
-
-Users listed in the server's `hsm_admin` configuration for a given HSM instance are
-its **admins**. Admins bypass all permission checks for that HSM — they can create,
-destroy, and perform any operation on its keys.
-
-### Permission evaluation for HSM keys
-
-```text
-Request arrives for operation OP on key hsm::::::
-│
-├─ Is the user an HSM admin for this instance?  ──▶  YES → Granted
-│
-├─ Does the user have OP explicitly granted?  ──────▶  YES → Granted
-│
-├─ Is OP = Export and user has Get?  ───────────────▶  YES → Granted
-├─ Is OP = Get   and user has Export?  ─────────────▶  YES → Granted
-│
-└─ Otherwise  ──────────────────────────────────────────────▶  Denied
-```

-### What can and cannot be delegated
-
-| Operation                                                                |    Delegable via `grant`?    | Notes                                                    |
-| ------------------------------------------------------------------------ | :--------------------------: | -------------------------------------------------------- |
-| `encrypt`, `decrypt`, `sign`, `mac`                                      |             Yes              | All standard cryptographic operations                    |
-| `get`                                                                    |             Yes              | Also implies `export` (equivalence)                      |
-| `export`                                                                 |             Yes              | Also implies `get` (equivalence)                         |
-| `get_attributes`, `locate`                                               |             Yes              |                                                          |
-| `set_attribute`, `modify_attribute`, `add_attribute`, `delete_attribute` |             Yes              | Operate on KMS metadata only; do not access HSM hardware |
-| `create`                                                                 | Yes (admin to another admin) | Non-admin cannot receive `create` on HSM                 |
-| `destroy`                                                                |            **No**            | Blocked — admin-only, cannot be delegated                |
-| `revoke`                                                                 |            **No**            | Blocked — HSM objects do not use KMIP lifecycle states   |
-
-!!! warning
-    Unlike regular KMS keys, **granting `Get` on an HSM key does not imply `encrypt`,
-    `decrypt`, `sign`, or any other operation**. Each operation must be granted
-    individually.
-
-See the [HSM operations](../hsm_support/hsm_operations.md) page for HSM admin
-configuration details.
-
-## Authentication vs. authorization
-
-It is important to distinguish authentication from authorization:
-
-- **Authentication** determines _who_ the user is. The KMS supports TLS client certificates, JWT tokens, and API tokens.
-  See the [Authentication](authentication.md) page for details on how to configure these methods and how user identities
-  are established.
-- **Authorization** determines _what_ an authenticated user is allowed to do with a given cryptographic object. This is
-  the permission model described on this page.
-
-!!! tip
-    An **API token** (used for authentication) is not the same thing as a **symmetric key** stored in the KMS.
-    The API token proves the user's identity; the symmetric key is a cryptographic object the user may or may not
-    have permission to use.
-
-## Typical workflow: per-user keys with limited permissions
-
-!!! info "Permissions are managed at runtime, not in `kms.toml`"
-    The `kms.toml` configuration file controls **server-level** settings only (authentication methods, database backend,
-    TLS, privileged users, etc.). It does **not** contain any user-to-key permission mapping.
-    Per-object access rights are managed dynamically at runtime through the REST API (`/access/grant`, `/access/revoke`)
-    or the CLI (`ckms access-rights grant` / `ckms access-rights revoke`).
-    The only authorization-related setting in `kms.toml` is `privileged_users`, which restricts who can create or import
-    new objects (see [Privileged users](#privileged-users) above).
-
-A common deployment pattern is to have an administrator create one symmetric key per user and grant only the
-operations each user needs (e.g. `encrypt` and `decrypt`).
-
-### Step 1 — Create the key (as admin/owner)
-
-```bash
-# The admin creates a 256-bit AES key and tags it for easy lookup
-ckms sym keys create --algorithm aes --number-of-bits 256 --tag user-alice-key
-```
-
-The command returns the key's unique identifier, for example `a]b2c3d4-...`.
-
-### Step 2 — Grant limited permissions
-
-```bash
-# Grant only encrypt and decrypt to alice (identified by her authenticated username)
-ckms access-rights grant alice@example.com -i a]b2c3d4-... encrypt decrypt
-```
-
-Alice can now encrypt and decrypt using this key, but she **cannot** export it, destroy it, or perform any other
-operation on it.
-
-### Step 3 — Alice uses the key
-
-Alice authenticates to the KMS (via her client certificate, JWT token, or API token) and calls the encrypt/decrypt
-endpoints referencing the key UID. The server verifies she holds the `encrypt` / `decrypt` permission before
-proceeding.
-
-### Step 4 — Revoke access (if needed)
-
-```bash
-ckms access-rights revoke alice@example.com -i a]b2c3d4-... encrypt decrypt
-```
-
-!!! note
-    Do **not** grant `get` if you only want to allow encrypt/decrypt — `get` is a super-privilege that implies all
-    object-level operations (see above).
-
-## Access management endpoints
-
-The KMS exposes the following REST endpoints to manage access rights:
-
-| Method | Endpoint                   | Description                                               |
-| ------ | -------------------------- | --------------------------------------------------------- |
-| POST   | `/access/grant`            | Grant operations on an object to a user                   |
-| POST   | `/access/revoke`           | Revoke operations on an object from a user                |
-| GET    | `/access/list/{object_id}` | List all access rights granted on an object (owner only)  |
-| GET    | `/access/owned`            | List all objects owned by the authenticated user          |
-| GET    | `/access/obtained`         | List all access rights obtained by the authenticated user |
-| GET    | `/access/create`           | Check whether the authenticated user can create objects   |
-| GET    | `/access/privileged`       | Check whether the authenticated user is privileged        |
-
-## Authorization rules summary
-
-| Scenario                                                | Access granted? |
-| ------------------------------------------------------- | :-------------: |
-| User is the object owner                                |     Always      |
-| User has the exact requested operation granted          |       Yes       |
-| User has `Get` granted (any operation except lifecycle) |       Yes       |
-| User has no matching permission                         |     Denied      |
-| User tries to grant/revoke their own permissions        |     Denied      |
-| Non-owner tries to grant permissions                    |     Denied      |

+# Authorization
+
+The Eviden KMS implements **two independent, composable authorization systems**. They can
+be used alone or together, depending on the deployment requirements.
+
+| System | Decides based on | Configured via |
+| ------ | ---------------- | -------------- |
+| **Native KMS permissions** | Object ownership + per-user grants | Runtime API (`/access/grant`, `/access/revoke`) and `kms.toml` (`privileged_users`) |
+| **OPA RBAC** | JWT roles + domain scoping | Rego policy on an OPA sidecar + Eviden Authentication Server |
+
+The two systems are **fully decoupled**: OPA knows nothing about native KMS grants, and
+native KMS knows nothing about OPA roles. They can be combined as a dual-gate but never
+share internal state.
+
+---
+
+## The three authorization modes
+
+| Mode | Name | `--opa-url` | `--opa-mode` | Description |
+| :--: | ---- | ----------- | ------------ | ----------- |
+| 1 | [Native KMS](mode1.md) | _(unset)_ | _(n/a)_ | Only native ownership + grants. Default. |
+| 2 | [Exclusive OPA](mode2.md) | set | `exclusive` | Only OPA decides. Native KMS is bypassed. |
+| 3 | [Enforcing](mode3.md) | set | `enforcing` | OPA first, then native KMS. Both must allow. |
+

+

+
+## OPA role model
+
+Roles are stored per-user per-realm in the Authentication Server's `userpass` table as a
+JSON array. OPA evaluates them with existential (union) semantics — any matching role is
+sufficient.
+
+```mermaid
+graph TD
+    SA["SuperAdmin
    cross-domain"] -->|subsumes| DA
+    DA["DomainAdmin
    full access, own domain"] -->|subsumes| CO
+    DA -->|subsumes| AU
+    CO["CryptoOfficer
    key lifecycle, own domain"] -->|subsumes| US
+    AU["Auditor
    read-only, own domain"]
+    US["User
    crypto-use only, own domain"]
+```
+
+| Role | Allowed operations | Domain-scoped? |
+| ---- | ------------------ | :------------: |
+| `SuperAdmin` | All KMIP operations | No |
+| `DomainAdmin` | All KMIP operations | **Yes** |
+| `CryptoOfficer` | create, import, get, export, locate, get_attributes, set_attribute, modify_attribute, delete_attribute, add_attribute, activate, revoke, archive, recover, destroy, rekey, rekey_key_pair | **Yes** |
+| `Auditor` | locate, get, get_attributes, list_access, query_access, mac_verify | **Yes** |
+| `User` | encrypt, decrypt, sign, verify, mac, mac_verify, derive_key, locate, get_attributes | **Yes** |
+
+### Object owner override
+
+Regardless of role, the object **owner** always has full access. The `is_owner` flag is
+computed by the KMS and included in the OPA input.
+
+---
+
+## Domain model
+
+Domain-based isolation enforces "within own domain" scoping for `DomainAdmin`,
+`CryptoOfficer`, `Auditor`, and `User` roles.
+
+```mermaid
+graph LR
+    subgraph D1["Domain: acme.com"]
+        U1["alice (DomainAdmin)"] --> K1["key-aes-256"]
+        U2["bob (CryptoOfficer)"] --> K1
+    end
+    subgraph D2["Domain: partner.io"]
+        U3["carol (DomainAdmin)"] --> K2["key-rsa-4096"]
+    end
+    SA["SuperAdmin"] --> K1
+    SA --> K2
+```
+
+- **User domain** (`user_domain`) — from the `as_domain` JWT private claim.
+- **Object domain** (`object_domain`) — stamped at creation from the creator's `user_domain`;
+  stored immutably in the `domain` column of the `objects` table.
+- **Object-less operations** (e.g. `Create`) — `object_domain` = `user_domain`.
+
+!!! note "Existing objects (pre-migration)"
+    Objects created before RBAC deployment have `domain = ""`. They remain accessible to
+    their owner but invisible to domain-scoped role rules. Only `SuperAdmin` can access
+    them via the role path.
+
+---
+
+## JWT claims from the Authentication Server
+
+The Authentication Server embeds two claims in the JWT:
+
+| Claim | Type | Description | Specification |
+| ----- | ---- | ----------- | ------------- |
+| `roles` | `string[]` | RBAC roles | RFC 9068 §2.2.3.1, RFC 7643 §4.1.2 |
+| `as_domain` | `string` | User's domain | RFC 7519 §4.3 (private claim) |
+
+Example decoded JWT:
+
+```json
+{
+  "sub": "alice@acme.com",
+  "iss": "https://auth.acme.com",
+  "exp": 1720000000,
+  "roles": ["CryptoOfficer"],
+  "as_domain": "acme.com"
+}
+```
+
+Non-JWT authentication (mTLS, API token) → `roles: []`, `user_domain: ""` → all
+role-based rules deny (fail-closed).
+
+---
+
+## OPA input document
+
+On every KMIP operation (in Modes 2 and 3), the KMS sends:
+
+```json
+{
+  "input": {
+    "user":          "alice@acme.com",
+    "user_domain":   "acme.com",
+    "roles":         ["CryptoOfficer"],
+    "operation":     "create",
+    "object_uid":    "*",
+    "object_domain": "acme.com",
+    "is_owner":      false
+  }
+}
+```
+
+| Field | Source | Default |
+| ----- | ------ | ------- |
+| `user` | JWT `sub` / TLS CN / API-token id | — |
+| `user_domain` | JWT `as_domain` | `""` |
+| `roles` | JWT `roles` (RFC 9068) | `[]` |
+| `operation` | KMIP operation name (snake_case) | — |
+| `object_uid` | Target object UID | `"*"` |
+| `object_domain` | `objects.domain` column | `user_domain` |
+| `is_owner` | `user == object.owner` | `false` |
+
+Response: `{"result": true}`. Any error or non-`true` value → `false` (fail-closed).
+
+---
+
+## Ceremony super-admin
+
+The KMS ceremony super-admin (Shamir split-key activation) operates **exclusively
+inside the native KMS permission gate** and is invisible to OPA in all modes:
+
+- **Mode 1** — ceremony super-admin grants unrestricted access as today.
+- **Mode 2** — ceremony super-admin has no effect (native KMS gate is not consulted).
+- **Mode 3** — ceremony super-admin takes effect in Gate 2 only, after OPA has allowed.
+
+---
+
+## Configuration reference
+
+### KMS server (`kms.toml`)
+
+```toml
+[opa]
+# OPA server base URL. Omit to disable OPA (Mode 1).
+opa_url  = "http://localhost:8181"
+
+# "exclusive" → Mode 2; "enforcing" → Mode 3.
+opa_mode = "enforcing"
+```
+
+### Authentication Server
+
+Roles are managed per-user per-realm via the admin API:
+
+```bash
+curl -X PUT https://auth.acme.com/realms/acme/credentials/alice \
+  -H "Authorization: Bearer " \
+  -H "Content-Type: application/json" \
+  -d '{"password": "...", "roles": ["CryptoOfficer"], "domain": "acme.com"}'
+```
+
+### OPA sidecar
+
+```bash
+opa run --server --addr :8181 test_data/opa/kms.rego
+```
+
+For production: use OPA bundles for hot-reloadable policy updates.

+# Mode 1 — Native KMS Permissions
+
+When no OPA server is configured (`--opa-url` is unset), the KMS uses its built-in
+permission system. This is the default mode.
+
+```toml
+# kms.toml — no [opa] section needed
+```
+
+---
+
+## How it works

+## Core principles
+
+### Ownership
+
+Every cryptographic object has an assigned owner. Ownership is established when an
+object is created via `Create`, `CreateKeyPair`, or `Import`. The owner can perform
+**all** KMIP operations on their objects.
+
+### Access rights delegation
+
+Owners can grant access rights, allowing other users to perform specific KMIP
+operations on an object. The owner retains the authority to withdraw these access
+rights at any time.
+
+---
+
+## Delegable KMIP operations
+
+| Operation           | Description                                                     |
+| ------------------- | --------------------------------------------------------------- |
+| `create`            | Create new cryptographic objects (symmetric keys, key pairs, …) |
+| `certify`           | Issue or renew X.509 certificates                               |
+| `decrypt`           | Decrypt ciphertext using a managed key                          |
+| `derive_key`        | Derive a new key from an existing key                           |
+| `destroy`           | Permanently destroy an object                                   |
+| `encrypt`           | Encrypt plaintext using a managed key                           |
+| `export`            | Export an object (key material + metadata) from the KMS         |
+| `get`               | Retrieve an object — **this is a super-privilege** (see below)  |
+| `get_attributes`    | Read the KMIP attributes of an object                           |
+| `hash`              | Compute a cryptographic hash                                    |
+| `import`            | Import an external object into the KMS                          |
+| `locate`            | Search for objects matching given attributes                    |
+| `mac`               | Compute a Message Authentication Code                           |
+| `revoke`            | Revoke (deactivate) an object                                   |
+| `rekey`             | Re-key an existing symmetric key                                |
+| `sign`              | Generate a digital signature                                    |
+| `signature_verify`  | Verify a digital signature                                      |
+| `validate`          | Validate a certificate chain                                    |
+| `set_attribute`     | Set (replace) an attribute on an object                         |
+| `modify_attribute`  | Modify an existing attribute on an object                       |
+| `add_attribute`     | Add a new attribute value to an object                          |
+| `delete_attribute`  | Remove an attribute from an object                              |
+
+Multiple operations can be granted or revoked in a single call:
+
+```bash
+# Grant encrypt and decrypt to user "alice"
+ckms access-rights grant alice -i  encrypt decrypt
+
+# Revoke the get privilege from user "bob"
+ckms access-rights revoke bob -i  get
+```
+
+---
+
+## The `Get` super-privilege
+
+The `Get` operation acts as a **super-privilege that implies every other object-level
+operation** (except lifecycle operations `revoke` and `destroy`).
+
+The evaluation order:
+
+1. **Owner check** — owner always has full access.
+2. **Explicit permission** — user has been granted the specific operation.
+3. **`Get` fallback** — user holds `Get` → access granted for any non-lifecycle operation.
+
+| Granted permissions  | Can `encrypt`? | Can `export`? | Can `destroy`? |
+| -------------------- | :------------: | :-----------: | :------------: |
+| `encrypt`            |      Yes       |      No       |       No       |
+| `get`                |      Yes       |      Yes      |       No       |
+| `encrypt`, `destroy` |      Yes       |      No       |      Yes       |
+| `get`, `destroy`     |      Yes       |      Yes      |      Yes       |
+
+!!! warning "Security implication"
+    Grant `get` with care. If you only need a user to encrypt data, grant `encrypt` — not `get`.
+
+!!! note
+    `destroy` and `revoke` are **never** implied by `get`. They require explicit grants.
+
+---
+
+## Special handling of the `Create` permission
+
+The `Create` operation controls whether a user can create *new* objects. It is stored
+against the wildcard object identifier `*`.
+
+- When granting or revoking `create`, no object UID is required.
+- `Create` can be combined with object-level operations in the same request.
+
+---
+
+## Privileged users
+
+By default all users can create or import objects. When `privileged_users` is
+configured in `kms.toml`:
+
+- Only privileged users can create/import objects.
+- Privileged users can grant/revoke `create` to regular users.
+- Regular users cannot create unless explicitly granted by a privileged user.
+- Privileged users cannot revoke creation from other privileged users.
+
+### Operations gated by the privileged-user restriction
+
+| Operation        | Reason                                                  |
+| ---------------- | ------------------------------------------------------- |
+| `Create`         | Creates a new symmetric key or secret data object       |
+| `CreateKeyPair`  | Creates a new asymmetric key pair                       |
+| `Import`         | Imports an external object into the KMS                 |
+| `Register`       | Registers an externally-generated object                |
+| `Certify`        | May create a new key pair when issuing a certificate    |
+| `ReKey`          | Creates a new replacement symmetric key                 |
+| `ReKeyKeyPair`   | Creates a new replacement asymmetric key pair           |
+
+---
+
+## The wildcard user `*`
+
+!!! important "The Wildcard User: *"
+    Granting a permission to user `*` makes it effective for **all** authenticated users.
+    Per-user grants are merged with wildcard grants during evaluation.
+
+---
+
+## HSM keys
+
+Keys stored in an HSM follow a stricter permission model:
+
+| Aspect                        | KMS keys                              | HSM keys                                        |
+| ----------------------------- | ------------------------------------- | ----------------------------------------------- |
+| Key material stored in        | KMS database (encrypted)              | HSM hardware                                    |
+| `Get` is a super-privilege    | Yes                                   | **No** — each operation must be granted         |
+| `Get` ↔ `Export` equivalence  | No                                    | **Yes** — holding either grants both            |
+| `Destroy` / `Revoke` delegable | Yes                                  | **No** — admin-only                             |
+| `Create`                      | Any user (or privileged)              | HSM admin only                                  |
+
+See the [HSM operations](../../hsm_support/hsm_operations.md) page for details.

+## Typical workflow
+
+### Step 1 — Create the key (as admin/owner)
+
+```bash
+ckms sym keys create --algorithm aes --number-of-bits 256 --tag user-alice-key
+```
+
+### Step 2 — Grant limited permissions
+
+```bash
+ckms access-rights grant alice@example.com -i  encrypt decrypt
+```
+
+### Step 3 — Alice uses the key
+
+Alice authenticates and calls encrypt/decrypt referencing the key UID.
+
+### Step 4 — Revoke access
+
+```bash
+ckms access-rights revoke alice@example.com -i  encrypt decrypt
+```

+# Mode 2 — Exclusive OPA (RBAC)
+
+When the OPA server is configured with `opa_mode = "exclusive"`, OPA is the **sole
+authorization decision maker**. The native KMS permission system (ownership, grants)
+is completely bypassed.
+
+```toml
+# kms.toml — Mode 2
+[opa]
+opa_url  = "http://localhost:8181"
+opa_mode = "exclusive"
+```
+
+| Environment variable | Example |
+| -------------------- | ------- |
+| `KMS_OPA_URL`        | `http://localhost:8181` |
+| `KMS_OPA_MODE`       | `exclusive` |
+
+---
+
+## Prerequisites
+
+- **JWT authentication required** — all users must authenticate via JWT issued by the
+  Eviden Authentication Server. The JWT must contain the `roles` and `as_domain` claims.
+- **Non-JWT auth is fail-closed** — mTLS and API token users receive `roles: []` in the
+  OPA input, causing all role-based rules to evaluate to `false`.
+- **Native KMS grants are ignored** — even if a user has explicit grants in the KMS
+  database, they are not consulted.

+## OPA decision flowchart
+
+The Rego policy evaluates rules top-to-bottom. The first matching rule grants access:

+```
+
+If OPA is configured but unreachable, **all requests are denied**. This is
+intentional: a crashed sidecar does not degrade the KMS to open access.
+
+---
+
+## What is NOT evaluated in Mode 2
+
+| Native KMS concept | Evaluated? | Reason |
+| ------------------ | :--------: | ------ |
+| Object ownership grants | No | OPA handles `is_owner` directly |
+| Per-user operation grants | No | Replaced by role-based rules |
+| `Get` super-privilege | No | OPA does not implement this shortcut |
+| Privileged users (creation rights) | No | OPA controls who can `Create` |
+| HSM admin bypass | No | OPA handles all HSM key decisions |
+| Ceremony super-admin | No | Native KMS gate is not consulted |
+
+---
+
+## Deploying the OPA sidecar
+
+Minimal start:
+
+```bash
+opa run --server --addr :8181 kms.rego
+```
+
+Production (hot-reloadable via bundles):
+
+```bash
+opa run --server --addr :8181 \
+  --set bundles.kms.service=policy-service \
+  --set bundles.kms.resource=kms/bundle.tar.gz \
+  --set services.policy-service.url=https://policy.example.com
+```
+
+The policy can be updated at runtime without restarting KMS or OPA.
+
+---
+
+## Debugging denied requests
+
+Query the debug endpoint to see which rules matched:
+
+```bash
+curl -s -X POST http://localhost:8181/v1/data/kms/reason \
+  -H "Content-Type: application/json" \
+  -d '{
+    "input": {
+      "user": "alice@acme.com",
+      "user_domain": "acme.com",
+      "roles": ["CryptoOfficer"],
+      "operation": "destroy",
+      "object_uid": "key-123",
+      "object_domain": "acme.com",
+      "is_owner": false
+    }
+  }'
+```
+
+Response: `{"result": ["crypto_officer"]}` — the `CryptoOfficer` role allows `destroy`.
+
+If the response contains `"denied"`, no rule matched.

+# Mode 3 — Enforcing (OPA + Native KMS)
+
+When the OPA server is configured with `opa_mode = "enforcing"`, **both** authorization
+systems must allow the request. OPA acts as the first gate; if it denies, the request
+is rejected immediately. If OPA allows, the native KMS permission system runs as a
+second gate with **veto power**.
+
+```toml
+# kms.toml — Mode 3
+[opa]
+opa_url  = "http://localhost:8181"
+opa_mode = "enforcing"
+```
+
+| Environment variable | Example |
+| -------------------- | ------- |
+| `KMS_OPA_URL`        | `http://localhost:8181` |
+| `KMS_OPA_MODE`       | `enforcing` |
+
+---
+
+## When to use Mode 3
+
+- **Migration path** — you have an existing Mode 1 deployment with fine-grained grants
+  and want to layer RBAC guardrails without discarding them.
+- **Defence in depth** — role-based rules prevent broad misuse; per-object grants
+  enforce least-privilege on individual keys.
+- **Compliance** — some standards require both role-based and object-level access
+  control to be active simultaneously.

+
+### Gate 1 detail — OPA evaluation
+
+Same as [Mode 2](mode2.md): role hierarchy, domain scoping, owner override.
+
+### Gate 2 detail — Native KMS evaluation
+
+Same as [Mode 1](mode1.md): owner → HSM admin → explicit grant → Get wildcard.
+
+The ceremony super-admin (Shamir split-key) operates exclusively within Gate 2 and is
+invisible to OPA.

+
+## Interaction scenarios
+
+| OPA decision | Native KMS decision | Final result | Explanation |
+| :----------: | :-----------------: | :----------: | ----------- |
+| Allow        | Allow (owner)       | **Granted**  | Both gates pass |
+| Allow        | Allow (grant)       | **Granted**  | Role allows + explicit grant exists |
+| Allow        | Deny                | **Denied**   | Role allows but no object-level permission |
+| Deny         | _(not evaluated)_   | **Denied**   | Short-circuit: OPA veto |
+| Unreachable  | _(not evaluated)_   | **Denied**   | Fail-closed: OPA down |
+| Allow        | Allow (HSM admin)   | **Granted**  | HSM admin passes Gate 2 |
+| Allow        | Allow (ceremony SA) | **Granted**  | Ceremony super-admin passes Gate 2 |
+
+---
+
+## Practical example
+
+Alice has `CryptoOfficer` role in domain `acme.com` and was granted `encrypt` on key
+`key-123` (also in domain `acme.com`).
+
+```text
+Gate 1 (OPA): CryptoOfficer + same domain + "encrypt" in crypto_officer_ops → Allow ✓
+Gate 2 (KMS): Alice has explicit "encrypt" grant on key-123 → Allow ✓
+Final: Granted
+```
+
+Now Alice tries `destroy` on `key-123`:
+
+```text
+Gate 1 (OPA): CryptoOfficer + same domain + "destroy" in crypto_officer_ops → Allow ✓
+Gate 2 (KMS): Alice has no "destroy" grant and is not owner → Deny ✗
+Final: Denied
+```
+
+OPA role allows it, but the native KMS gate vetoes because no explicit grant exists.
+
+---
+
+## Comparison with Mode 2
+
+| Aspect | Mode 2 (Exclusive) | Mode 3 (Enforcing) |
+| ------ | :----------------: | :----------------: |
+| OPA consulted | Yes | Yes |
+| Native KMS consulted | No | Yes (second gate) |
+| OPA deny = final deny | Yes | Yes |
+| Native KMS can veto | N/A | **Yes** |
+| Ceremony super-admin | Suspended | Active (in Gate 2) |
+| Per-object grants used | No | **Yes** |
+| HSM admin bypass | No | **Yes** (in Gate 2) |

+# RBAC, OPA, JWT and Identity Provider Setup
+
+This guide walks through setting up the full Role-Based Access Control (RBAC) stack
+for Cosmian KMS: an Identity Provider (IdP) that issues JWTs carrying role claims,
+an OPA sidecar that evaluates the Rego policy, and a KMS server wired to both.
+

+
+## Step 1 — Identity Provider: issuing JWTs with role claims
+
+The KMS reads three JWT claims for RBAC:
+
+| Claim | RFC | Content | Example |
+|---|---|---|---|
+| `sub` | RFC 7519 §4.1.2 | User identity (forwarded to OPA as `input.user`) | `"alice@acme.com"` |
+| `roles` | RFC 9068 §2.2.3.1 | Array of role strings | `["CryptoOfficer"]` |
+| `as_rid` | private (RFC 7519 §4.3) | Realm ID = tenant domain (forwarded as `input.user_domain`) | `"acme.com"` |
+
+> The KMS accepts both **`as_rid`** (Cosmian Auth Server) and **`as_domain`** (legacy alias)
+> for the domain claim. Third-party IdPs should map their tenant field to `as_rid`.
+
+### Cosmian Authentication Server (recommended)
+
+The Cosmian Auth Server is the reference IdP for this feature. It supports realms
+(= domains) and per-user role assignment natively, and emits the `roles` and
+`as_rid` claims required by the KMS OPA policy.
+
+#### Build and start
+
+```bash
+cd /path/to/authentication   # the authentication workspace root
+
+# Build
+cargo build -p auth_server
+
+# Start with the bundled dev configuration (self-signed certs, SQLite, no setup needed)
+cargo run -p auth_server -- server/auth_server.dev.toml
+```
+
+The server listens on `https://localhost:8443`. On first start it auto-creates:
+
+- Super-admin realm `_` — login: `admin` / `change_me`
+- Dev realm `dev-realm` — login: `realm-admin` / `change_me`
+
+The test CA certificate for TLS verification:
+```
+server/src/tests/certificates/ec/auth.server.cert.pem  (server cert, used by KMS)
+server/src/tests/certificates/ec/auth.ca.pem           (CA cert, used by curl)
+```
+
+#### Provision a realm and users
+
+The realm `id` becomes the `as_rid` claim in the JWT and the `object_domain` used by
+the OPA `same_domain` rule.
+
+```bash
+CA=/path/to/authentication/server/src/tests/certificates/ec/auth.ca.pem
+
+# 1 — Login as super-admin (stores session cookie)
+curl -s --cacert $CA -c /tmp/auth-admin.txt \
+  -X POST "https://localhost:8443/login?realm=_" \
+  -u "admin:change_me" \
+  -H "Content-Type: application/json" \
+  -d '{"public_key_pem":null,"totp_code":null}'
+
+# 2 — Create realm "acme.com"
+curl -s --cacert $CA -b /tmp/auth-admin.txt \
+  -X POST "https://localhost:8443/admins/realms" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "id": "acme.com",
+    "auth_params": {
+      "username_password_params": {"allow_expired_passwords": false}
+    },
+    "session_max_age_seconds": 3600,
+    "session_max_stale_age_seconds": 7200
+  }'
+
+# 3 — Create a user with role CryptoOfficer
+#     Passwords must be hashed: Argon2id(password, salt=base64(SHA-256(username)))
+#     Auth server uses argon2 v0.4.1 defaults: m=4096, t=3, p=1
+HASH=$(python3 - << 'EOF'
+import hashlib, base64
+from argon2 import PasswordHasher
+username, password = "alice", "alice-pass"
+salt = base64.b64encode(hashlib.sha256(username.encode()).digest()).rstrip(b"=")
+ph = PasswordHasher(time_cost=3, memory_cost=4096, parallelism=1, hash_len=32)
+print(ph.hash(password, salt=base64.b64decode(salt + b"==")))
+EOF
+)
+
+curl -s --cacert $CA -b /tmp/auth-admin.txt \
+  -X POST "https://localhost:8443/realms/acme.com/userpass" \
+  -H "Content-Type: application/json" \
+  -d "{
+    \"realm\": \"acme.com\",
+    \"username\": \"alice\",
+    \"password\": \"$HASH\",
+    \"change_password\": false,
+    \"roles\": [\"CryptoOfficer\"],
+    \"domain\": \"acme.com\"
+  }"
+```
+
+Repeat step 3 for each user, adjusting `username`, `password`, `roles`, and optionally
+`domain` (defaults to realm `id` if omitted).
+
+#### Obtain a JWT
+
+```bash
+JWT=$(curl -s --cacert $CA -D - \
+  -X POST "https://localhost:8443/login?realm=acme.com" \
+  -u "alice:alice-pass" \
+  -H "Content-Type: application/json" \
+  -d '{"public_key_pem":null,"totp_code":null}' \
+  | grep -i "set-cookie: _ea_=" \
+  | sed 's/.*_ea_=\([^;]*\).*/\1/' | tr -d '\r')
+
+echo "JWT: $JWT"
+# Inspect claims: echo $JWT | cut -d. -f2 | base64 -d 2>/dev/null | python3 -m json.tool
+```
+
+The JWT is a standard ES256-signed token (or the key type configured in
+`tls_params`). Its payload contains:
+
+```json
+{
+  "sub":    "alice",
+  "iss":    "cosmian-auth-test",
+  "roles":  ["CryptoOfficer"],
+  "as_rid": "acme.com",
+  "exp":    
+}
+```
+
+#### Configure KMS to trust the auth server
+
+The KMS validates JWTs against the auth server's JWKS endpoint
+(`https:///public/jwks`).
+
+```toml
+# kms.toml
+[idp_auth]
+# Format: "issuer,jwks_uri"
+# The issuer string must match the `iss` claim in the JWT.
+jwt_auth_provider = ["cosmian-auth-test,https://localhost:8443/public/jwks"]
+
+[opa]
+opa_url  = "http://localhost:8181"
+opa_mode = "enforcing"
+```
+
+Because the auth server uses a self-signed certificate, start the KMS with the CA cert
+or with `--accept-invalid-certs` (dev only):
+
+```bash
+cargo run --features non-fips --bin cosmian_kms -- \
+  --database-type sqlite \
+  --sqlite-path /tmp/kms-data \
+  --jwt-auth-provider "cosmian-auth-test,https://localhost:8443/public/jwks" \
+  --opa-url http://localhost:8181 \
+  --opa-mode enforcing \
+  --accept-invalid-certs
+```
+
+#### Auth server REST API summary
+
+| Endpoint | Method | Auth | Description |
+|---|---|---|---|
+| `POST /login?realm=_` | Basic auth | — | Login as admin, receive `_ea_` session cookie |
+| `POST /login?realm=` | Basic auth | — | Login as user, receive `_ea_` JWT cookie |
+| `GET /public/jwks` | — | Public | JWKS endpoint (KMS fetches this to validate JWTs) |
+| `GET /public/roles` | — | Public | List of configured role names |
+| `POST /admins/realms` | JSON | Admin session | Create a realm |
+| `POST /admins` | JSON | Admin session | Create a realm-scoped admin account |
+| `POST /realms//userpass` | JSON | Admin session | Create a user with roles + domain |
+| `DELETE /realms//userpass/` | — | Admin session | Delete a user |
+| `GET /public/version` | — | Public | Server version |
+
+### Keycloak
+
+1. Create a realm (e.g. `acme`).
+2. Add a `roles` claim via a **Mapper** of type *User Attribute* or *User Realm Role*.
+3. Add a custom `as_rid` attribute mapper that reads a user attribute `domain`.
+4. The JWKS URI is `https:///realms//protocol/openid-connect/certs`.
+
+```toml
+# kms.toml — KMS side
+[idp_auth]
+jwt_auth_provider = ["https://keycloak.acme.com/realms/acme,https://keycloak.acme.com/realms/acme/protocol/openid-connect/certs"]
+```
+
+### Other OIDC providers (Okta, Auth0, Google)
+
+Any OIDC-compliant provider works as long as it can emit `roles` and `as_rid` (or `as_domain`) in the
+JWT. For providers that do not support custom claims natively, use a token transformation
+step (e.g. Okta hooks, Auth0 rules/actions).
+
+---
+
+## Step 2 — OPA server: deploy and load the Rego policy
+
+### Docker Compose (recommended for production)
+
+```yaml
+# docker-compose.yml
+services:
+  opa:
+    image: openpolicyagent/opa:edge-static-debug
+    ports:
+      - "8181:8181"
+    volumes:
+      - ./test_data/opa/kms.rego:/policies/kms.rego:ro
+    command:
+      - run
+      - --server
+      - --log-level=info
+      - --addr=0.0.0.0:8181
+      - /policies/kms.rego
+```
+
+```bash
+docker compose up -d opa
+```
+
+### Standalone Docker
+
+```bash
+docker run -d --name opa \
+  -p 8181:8181 \
+  -v "$(pwd)/test_data/opa/kms.rego:/policies/kms.rego:ro" \
+  openpolicyagent/opa:edge-static-debug \
+  run --server --log-level=info --addr=0.0.0.0:8181 /policies/kms.rego
+```
+
+### Verify OPA is ready
+
+```bash
+# Health check
+curl http://localhost:8181/health
+
+# Test a CryptoOfficer create request — expect {"result":true}
+curl -s -X POST http://localhost:8181/v1/data/kms/allow \
+  -H "Content-Type: application/json" \
+  -d '{
+    "input": {
+      "user": "alice@acme.com",
+      "user_domain": "acme.com",
+      "roles": ["CryptoOfficer"],
+      "operation": "create",
+      "object_uid": "*",
+      "object_domain": "acme.com",
+      "is_owner": false
+    }
+  }'
+```
+
+---
+
+## Step 3 — KMS server: wire JWT auth and OPA
+
+### kms.toml
+
+```toml
+[http]
+hostname = "0.0.0.0"
+port     = 9998
+
+[db]
+database_type = "sqlite"
+sqlite_path   = "/var/lib/kms/data"
+
+# ── Identity Provider ─────────────────────────────────────────────────────
+[idp_auth]
+# Format: "issuer,jwks_uri,audience1,audience2,..."
+# For Cosmian Auth Server: issuer = "cosmian-auth-test", JWKS = /public/jwks
+jwt_auth_provider = ["cosmian-auth-test,https://localhost:8443/public/jwks"]
+# For Keycloak:
+# jwt_auth_provider = ["https://keycloak.acme.com/realms/acme"]
+
+# ── OPA sidecar ──────────────────────────────────────────────────────────
+[opa]
+opa_url  = "http://localhost:8181"  # or "http://opa:8181" in Docker Compose
+opa_mode = "enforcing"              # "exclusive" or "enforcing"
+```
+
+### Environment variables (alternative to kms.toml)
+
+| Variable | Example | Description |
+|---|---|---|
+| `KMS_JWT_AUTH_PROVIDER` | `https://auth.acme.com` | IdP issuer (+ optional JWKS URI and audiences) |
+| `KMS_OPA_URL` | `http://localhost:8181` | OPA base URL |
+| `KMS_OPA_MODE` | `enforcing` | `exclusive` or `enforcing` |
+
+### cargo run (development)
+
+```bash
+RUST_LOG="cosmian_kms_server=debug" \
+cargo run --features non-fips --bin cosmian_kms -- \
+  --database-type sqlite \
+  --sqlite-path /tmp/kms-data \
+  --jwt-auth-provider "cosmian-auth-test,https://localhost:8443/public/jwks" \
+  --opa-url http://localhost:8181 \
+  --opa-mode enforcing \
+  --accept-invalid-certs
+```
+
+---
+
+## Step 4 — Obtain a JWT and call the KMS
+
+### With the Cosmian Authentication Server
+
+The Cosmian Auth Server issues JWTs via a direct login API (cookie-based, not OAuth2
+PKCE). The `ckms login` command **cannot** be used with it. Instead, extract the JWT
+from the `_ea_` cookie and place it in `ckms.toml` directly.
+
+```bash
+CA=/path/to/authentication/server/src/tests/certificates/ec/auth.ca.pem
+
+# Login as alice in realm acme.com — JWT comes back as the _ea_ cookie
+JWT=$(curl -s --cacert $CA -D - \
+  -X POST "https://localhost:8443/login?realm=acme.com" \
+  -u "alice:alice-pass" \
+  -H "Content-Type: application/json" \
+  -d '{"public_key_pem":null,"totp_code":null}' \
+  | grep -i "set-cookie: _ea_=" \
+  | sed 's/.*_ea_=\([^;]*\).*/\1/' | tr -d '\r')
+
+# Inspect the JWT claims (optional)
+echo $JWT | cut -d. -f2 | base64 -d 2>/dev/null | python3 -m json.tool
+
+# Write to ckms.toml
+cat > /tmp/ckms-alice.toml << EOF
+[http_config]
+server_url           = "http://127.0.0.1:9998"
+accept_invalid_certs = false
+access_token         = "${JWT}"
+EOF
+
+# Use it
+cargo run --bin ckms -- -c /tmp/ckms-alice.toml sym keys create -t test-key
+```
+
+### With a standard OIDC provider (Keycloak, Okta, …): `ckms login`
+
+Standard OIDC providers support OAuth2 PKCE. Configure `ckms.toml` with OAuth2
+settings and use `ckms login` to obtain the token via a browser flow:
+
+```toml
+# ckms.toml
+[http_config]
+server_url = "http://localhost:9998"
+
+[http_config.oauth2_conf]
+client_id     = "ckms-client"
+client_secret = ""           # empty for PKCE-only flows
+authorize_url = "https://keycloak.acme.com/realms/acme/protocol/openid-connect/auth"
+token_url     = "https://keycloak.acme.com/realms/acme/protocol/openid-connect/token"
+scopes        = ["openid", "email"]
+```
+
+```bash
+ckms -c ckms.toml login   # opens browser → saves token to ckms.toml
+ckms -c ckms.toml sym keys create
+ckms -c ckms.toml logout
+```
+
+### Development: unsigned JWT (no IdP needed, requires `--features insecure`)
+
+The KMS server must be running with `--features insecure` (skips JWT signature and
+expiry validation). **Never use this in production.**
+
+```bash
+# Build a test JWT for a CryptoOfficer in domain acme.com
+PAYLOAD=$(echo -n '{"sub":"alice","as_rid":"acme.com","roles":["CryptoOfficer"],"iss":"test","exp":9999999999}' \
+  | base64 -w0 | tr '+/' '-_' | tr -d '=')
+JWT="eyJhbGciOiJub25lIn0.${PAYLOAD}."
+
+# Write it to a ckms config
+cat > /tmp/ckms-officer.toml << EOF
+[http_config]
+server_url = "http://127.0.0.1:9998"
+access_token = "${JWT}"
+EOF
+
+# Create a key as CryptoOfficer
+cargo run --bin ckms -- -c /tmp/ckms-officer.toml sym keys create -t test-key
+
+# Create a JWT for a User role
+PAYLOAD=$(echo -n '{"sub":"bob","as_rid":"acme.com","roles":["User"],"iss":"test","exp":9999999999}' \
+  | base64 -w0 | tr '+/' '-_' | tr -d '=')
+JWT_USER="eyJhbGciOiJub25lIn0.${PAYLOAD}."
+cat > /tmp/ckms-user.toml << EOF
+[http_config]
+server_url = "http://127.0.0.1:9998"
+access_token = "${JWT_USER}"
+EOF
+
+# Locate the key (User can read attributes) — allowed
+cargo run --bin ckms -- -c /tmp/ckms-user.toml locate --tag test-key
+
+# Destroy the key as User — denied by OPA (destroy ∉ user_ops)
+cargo run --bin ckms -- -c /tmp/ckms-user.toml sym keys destroy --key-id 
+```
+
+### Via the `-H` flag (one-off, no config file)
+
+```bash
+cargo run --bin ckms -- \
+  --url http://127.0.0.1:9998 \
+  -H "Authorization: Bearer ${JWT}" \
+  sym keys create -a aes
+```
+
+---
+
+## Role reference
+
+| Role | Domain scope | Allowed KMIP operations |
+|---|---|---|
+| `SuperAdmin` | All domains | All |
+| `DomainAdmin` | Own domain | All |
+| `CryptoOfficer` | Own domain | `create`, `create_key_pair`, `import`, `get`, `export`, `locate`, `get_attributes`, `set_attribute`, `modify_attribute`, `delete_attribute`, `add_attribute`, `activate`, `revoke`, `archive`, `recover`, `destroy`, `rekey`, `rekey_key_pair` |

+
+Object owners always have full access regardless of role.
+

+
+## OPA input document (reference)
+
+The KMS sends this JSON to `POST /v1/data/kms/allow` on every request:
+
+```json
+{
+  "input": {
+    "user":          "alice@acme.com",
+    "user_domain":   "acme.com",

+    "object_uid":    "*",
+    "object_domain": "acme.com",
+    "is_owner":      false
+  }
+}
+```
+
+| Field | Source | Notes |
+|---|---|---|
+| `user` | JWT `sub` | Authenticated identity |
+| `user_domain` | JWT `as_rid` (or legacy `as_domain`) | Empty `""` for non-JWT auth |
+| `roles` | JWT `roles` | Empty `[]` for non-JWT auth → fail-closed |
+| `operation` | KMIP operation tag | Lowercase snake_case (e.g. `"create"`, `"get_attributes"`) |
+| `object_uid` | Target object UID | `"*"` for object-less operations |
+| `object_domain` | `objects.domain` column | Equals `user_domain` for object-less operations |
+| `is_owner` | `user == object.owner` | Always grants access regardless of role |

+# {"result":["denied"]}          → no rule matched
+```
+
+### Enable trace logging on the KMS
+
+```bash
+RUST_LOG="cosmian_kms_server=trace" cargo run --bin cosmian_kms -- ...
+```
+
+Look for:
+- `cosmian_kms_server::middlewares::ensure_auth` — JWT extraction and role/domain parsing
+- `cosmian_kms_server::core::retrieve_object_utils` — OPA input document and decision
+- `cosmian_kms_server::core::opa::client` — HTTP round-trip timing and result
+
+### Enable OPA decision logging
+
+Add `--log-level=info` to OPA's startup flags (default in the Docker Compose service).
+OPA prints a structured JSON decision log for every query.
+
+---
+
+## Common problems
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `401 Unauthorized` | JWT missing or signature invalid | Check KMS `--jwt-auth-provider` issuer and JWKS URI |
+| `403 Forbidden` — OPA deny | Role not in JWT or cross-domain | Check `roles` claim; verify `as_rid` realm matches `object_domain` |
+| `403 Forbidden` — OPA unreachable | OPA not running or wrong port | Check `KMS_OPA_URL`; run `curl http://localhost:8181/health` |
+| `403 Forbidden` — Native KMS deny | Mode 3: no DB grant exists | Add grant with `ckms access-rights grant`, or switch to Mode 2 |
+| Empty `roles: []` in OPA input | Using mTLS or API-token auth | Roles only come from JWT; switch auth method or write a custom Rego rule |
+| `roles` claim not in JWT | IdP not configured to emit it | Add a `roles` claim mapper in Keycloak / Auth0 / Okta |

Subject: [PATCH 160/181] fix: resolve WASM/UI and Windows CI failures

- ui: JoinSplitKey initialValues now uses DEFAULT_SHARE_COUNT (3) instead
  of a hardcoded array of 2 entries, making the initial render consistent
  with the constant and fixing the 'join-share-id-2' unit test failure

- windows: set RUST_MIN_STACK=8388608 in cargo_test.ps1 to give test
  threads an 8 MB stack (matching Linux/macOS defaults); prevents the
  STATUS_STACK_OVERFLOW crash in integration_tests_use_ids_no_tags on
  debug builds where async state machines have larger stack frames

Subject: [PATCH 161/181] test: simplify auth-verifier provisioning, add OPA
 RBAC vector tests and multi-tenancy coverage

- Remove inline auth-server provisioning from vector_runner.rs (250+ lines);
  provisioning is now delegated to provision_opa_integration_users.sh
- Mark all test_vec_opa_* tests #[ignore] (run via `mise test:opa_rbac`)
- Replace silent Ok(()) skip with hard error when required env vars are absent
- Add test_vec_opa_mode_exclusive_other_domain_allowed: multi-tenancy positive
- Add auth_verifier multi-realm support; UI shows realm selector for multiple realms
- Add GET /ui/auth_method response field auth_verifier_realms
- Extend test_opa_rbac.sh Phase 3: start auth verifier, provision users, run Rust OPA tests
- Add login-page-auth-method-matrix.spec.ts: 10 Playwright tests for all auth method combos
- fix(clippy): use ? propagation in tests (no unwrap/expect)

 | System | Decides based on | Configured via |

+# OPA + Authentication Verifier Setup
+
+Step-by-step configuration guide for running Mode 2 (exclusive OPA) or
+Mode 3 (enforcing OPA + native KMS) with an OPA sidecar and the Cosmian
+Authentication Verifier as the JWT issuer.
+
+---
+
+## Step 1 — Authentication Verifier: issuing JWTs with role claims
+
+The KMS reads three JWT claims for RBAC:
+
+| Claim | RFC | Content | Example |
+|---|---|---|---|
+| `sub` | RFC 7519 §4.1.2 | User identity (forwarded to OPA as `input.user`) | `"alice@acme.com"` |
+| `roles` | RFC 9068 §2.2.3.1 | Array of role strings | `["CryptoOfficer"]` |
+| `as_rid` | private (RFC 7519 §4.3) | Realm ID = tenant domain (forwarded as `input.user_domain`) | `"acme.com"` |
+
+> The KMS accepts both **`as_rid`** (Cosmian Authentication Verifier) and **`as_domain`**
+> (legacy alias) for the domain claim. Third-party IdPs should map their tenant field to
+> `as_rid`.
+
+### Cosmian Authentication Verifier (recommended)
+
+The Cosmian Authentication Verifier is the reference IdP for this feature. It supports
+realms (= domains) and per-user role assignment natively, and emits the `roles` and
+`as_rid` claims required by the KMS OPA policy.
+
+→ **[Authentication Verifier installation and configuration](https://docs.cosmian.com/authentication_verifier/installation.html)**
+
+Once the Authentication Verifier is running, provision a realm and users:
+
+```bash
+CA=/path/to/auth-verifier/certs/auth.ca.pem
+
+# 1 — Login as super-admin (stores session cookie)
+curl -s --cacert $CA -c /tmp/auth-admin.txt \
+  -X POST "https://localhost:8443/login?realm=_" \
+  -u "admin:change_me" \
+  -H "Content-Type: application/json" \
+  -d '{"public_key_pem":null,"totp_code":null}'
+
+# 2 — Create realm "acme.com"
+curl -s --cacert $CA -b /tmp/auth-admin.txt \
+  -X POST "https://localhost:8443/admins/realms" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "id": "acme.com",
+    "auth_params": {
+      "username_password_params": {"allow_expired_passwords": false}
+    },
+    "session_max_age_seconds": 3600,
+    "session_max_stale_age_seconds": 7200
+  }'
+
+# 3 — Create a user with role CryptoOfficer
+#     Passwords must be hashed: Argon2id(password, salt=base64(SHA-256(username)))
+HASH=$(python3 - << 'EOF'
+import hashlib, base64
+from argon2 import PasswordHasher
+username, password = "alice", "alice-pass"
+salt = base64.b64encode(hashlib.sha256(username.encode()).digest()).rstrip(b"=")
+ph = PasswordHasher(time_cost=3, memory_cost=4096, parallelism=1, hash_len=32)
+print(ph.hash(password, salt=base64.b64decode(salt + b"==")))
+EOF
+)
+
+curl -s --cacert $CA -b /tmp/auth-admin.txt \
+  -X POST "https://localhost:8443/realms/acme.com/userpass" \
+  -H "Content-Type: application/json" \
+  -d "{
+    \"realm\": \"acme.com\",
+    \"username\": \"alice\",
+    \"password\": \"$HASH\",
+    \"change_password\": false,
+    \"roles\": [\"CryptoOfficer\"],
+    \"domain\": \"acme.com\"
+  }"
+```
+
+#### Obtain a JWT
+
+```bash
+JWT=$(curl -s --cacert $CA -D - \
+  -X POST "https://localhost:8443/login?realm=acme.com" \
+  -u "alice:alice-pass" \
+  -H "Content-Type: application/json" \
+  -d '{"public_key_pem":null,"totp_code":null}' \
+  | grep -i "set-cookie: _ea_=" \
+  | sed 's/.*_ea_=\([^;]*\).*/\1/' | tr -d '\r')
+
+# Inspect claims (optional)
+echo $JWT | cut -d. -f2 | base64 -d 2>/dev/null | python3 -m json.tool
+```
+
+#### Configure KMS to trust the Authentication Verifier
+
+```toml
+# kms.toml
+[idp_auth]
+# Format: "issuer,jwks_uri"
+jwt_auth_provider = ["cosmian-auth-test,https://localhost:8443/public/jwks"]
+
+[opa]
+opa_url  = "http://localhost:8181"
+opa_mode = "enforcing"
+```
+
+| Endpoint | Method | Description |
+|---|---|---|
+| `GET /public/jwks` | — | JWKS endpoint (KMS fetches this to validate JWTs) |
+| `GET /public/roles` | — | List of configured role names |
+| `POST /admins/realms` | JSON | Create a realm |
+| `POST /realms//userpass` | JSON | Create a user with roles + domain |
+| `DELETE /realms//userpass/` | — | Delete a user |
+
+---
+
+## Step 2 — OPA server: deploy and load the Rego policy
+
+### Docker Compose (recommended for production)
+
+```yaml
+# docker-compose.yml
+services:
+  opa:
+    image: openpolicyagent/opa:edge-static-debug

+jwt_auth_provider = ["cosmian-auth-test,https://localhost:8443/public/jwks"]
+
+[opa]
+opa_url  = "http://localhost:8181"
+opa_mode = "enforcing"
+```
+
+### Environment variables
+
+| Variable | Example | Description |
+|---|---|---|
+| `KMS_JWT_AUTH_PROVIDER` | `https://auth.acme.com` | IdP issuer (+ optional JWKS URI and audiences) |
+| `KMS_OPA_URL` | `http://localhost:8181` | OPA base URL |
+| `KMS_OPA_MODE` | `enforcing` | `exclusive` or `enforcing` |
+
+### Starting the KMS server
+
+```bash
+RUST_LOG="cosmian_kms_server=debug" \
+cosmian_kms \
+  --database-type sqlite \
+  --sqlite-path /tmp/kms-data \
+  --jwt-auth-provider "cosmian-auth-test,https://auth.acme.com/public/jwks" \
+  --opa-url http://localhost:8181 \
+  --opa-mode enforcing
+```
+
+---
+
+## Step 4 — Obtain a JWT and call the KMS
+
+### With the Cosmian Authentication Verifier
+
+```bash
+CA=/path/to/auth-verifier/certs/auth.ca.pem
+
+JWT=$(curl -s --cacert $CA -D - \
+  -X POST "https://auth.acme.com/login?realm=acme.com" \
+  -u "alice:alice-pass" \
+  -H "Content-Type: application/json" \
+  -d '{"public_key_pem":null,"totp_code":null}' \
+  | grep -i "set-cookie: _ea_=" \
+  | sed 's/.*_ea_=\([^;]*\).*/\1/' | tr -d '\r')
+
+cat > /tmp/ckms-alice.toml << EOF
+[http_config]
+server_url   = "http://kms.acme.com:9998"
+access_token = "${JWT}"
+EOF
+
+ckms -c /tmp/ckms-alice.toml sym keys create -t test-key
+```
+
+### Via PKCE / OAuth2 browser flow
+
+Standard OIDC providers that support OAuth2 PKCE can authenticate via a browser flow.
+Configure `ckms.toml` with the provider's `authorize_url` and `token_url`, then
+use `ckms login`:
+
+```toml
+# ckms.toml
+[http_config]
+server_url = "http://kms.acme.com:9998"
+
+[http_config.oauth2_conf]
+client_id     = "ckms-client"
+client_secret = ""
+authorize_url = "https://auth.acme.com/oauth2/authorize"
+token_url     = "https://auth.acme.com/oauth2/token"
+scopes        = ["openid", "email"]
+```
+
+```bash
+ckms -c ckms.toml login    # opens browser → saves token
+ckms -c ckms.toml sym keys create
+ckms -c ckms.toml logout
+```
+
+---
+
+## Debugging access denials
+
+### Query the OPA reason endpoint
+
+```bash
+curl -s -X POST http://localhost:8181/v1/data/kms/reasons \
+  -H "Content-Type: application/json" \
+  -d '{
+    "input": {
+      "user": "alice@acme.com",
+      "user_domain": "acme.com",
+      "roles": ["CryptoOfficer"],
+      "operation": "destroy",
+      "object_uid": "key-123",
+      "object_domain": "acme.com",
+      "is_owner": false
+    }
+  }'
+# {"result":["crypto_officer"]}  → allowed
+# {"result":["denied"]}          → no rule matched
+```
+
+### Enable trace logging on the KMS
+
+```bash
+RUST_LOG="cosmian_kms_server=trace" cosmian_kms ...
+```
+
+Look for `ensure_auth` (JWT parsing), `retrieve_object_utils` (OPA input), and
+`core::opa::client` (HTTP round-trip timing).
+
+---
+
+## Common problems
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `401 Unauthorized` | JWT missing or signature invalid | Check `--jwt-auth-provider` issuer and JWKS URI |
+| `403` — OPA deny | Role not in JWT or cross-domain | Check `roles` claim; verify `as_rid` matches `object_domain` |
+| `403` — OPA unreachable | OPA not running or wrong port | Check `KMS_OPA_URL`; run `curl http://localhost:8181/health` |
+| `403` — Native KMS deny | Mode 3: no DB grant | Add grant with `ckms access-rights grant`, or switch to Mode 2 |
+| Empty `roles: []` in OPA | mTLS or API-token auth | Roles only come from JWT |
+| `roles` not in JWT | Authentication Verifier not configured | Check that the realm emits `roles` and `as_rid` claims — see the [Authentication Verifier docs](https://docs.cosmian.com/authentication_verifier/installation.html) |

-# RBAC, OPA, JWT and Identity Provider Setup
-
-This guide walks through setting up the full Role-Based Access Control (RBAC) stack
-for Cosmian KMS: an Identity Provider (IdP) that issues JWTs carrying role claims,
-an OPA sidecar that evaluates the Rego policy, and a KMS server wired to both.

-
-## Step 1 — Identity Provider: issuing JWTs with role claims
-
-The KMS reads three JWT claims for RBAC:
-
-| Claim | RFC | Content | Example |
-|---|---|---|---|
-| `sub` | RFC 7519 §4.1.2 | User identity (forwarded to OPA as `input.user`) | `"alice@acme.com"` |
-| `roles` | RFC 9068 §2.2.3.1 | Array of role strings | `["CryptoOfficer"]` |
-| `as_rid` | private (RFC 7519 §4.3) | Realm ID = tenant domain (forwarded as `input.user_domain`) | `"acme.com"` |
-
-> The KMS accepts both **`as_rid`** (Cosmian Auth Server) and **`as_domain`** (legacy alias)
-> for the domain claim. Third-party IdPs should map their tenant field to `as_rid`.
-
-### Cosmian Authentication Server (recommended)
-
-The Cosmian Auth Server is the reference IdP for this feature. It supports realms
-(= domains) and per-user role assignment natively, and emits the `roles` and
-`as_rid` claims required by the KMS OPA policy.
-
-#### Build and start
-
-```bash
-cd /path/to/authentication   # the authentication workspace root
-
-# Build
-cargo build -p auth_server
-
-# Start with the bundled dev configuration (self-signed certs, SQLite, no setup needed)
-cargo run -p auth_server -- server/auth_server.dev.toml
-```
-
-The server listens on `https://localhost:8443`. On first start it auto-creates:
-
-- Super-admin realm `_` — login: `admin` / `change_me`
-- Dev realm `dev-realm` — login: `realm-admin` / `change_me`
-
-The test CA certificate for TLS verification:
-```
-server/src/tests/certificates/ec/auth.server.cert.pem  (server cert, used by KMS)
-server/src/tests/certificates/ec/auth.ca.pem           (CA cert, used by curl)
-```
-
-#### Provision a realm and users
-
-The realm `id` becomes the `as_rid` claim in the JWT and the `object_domain` used by
-the OPA `same_domain` rule.
-
-```bash
-CA=/path/to/authentication/server/src/tests/certificates/ec/auth.ca.pem
-
-# 1 — Login as super-admin (stores session cookie)
-curl -s --cacert $CA -c /tmp/auth-admin.txt \
-  -X POST "https://localhost:8443/login?realm=_" \
-  -u "admin:change_me" \
-  -H "Content-Type: application/json" \
-  -d '{"public_key_pem":null,"totp_code":null}'
-
-# 2 — Create realm "acme.com"
-curl -s --cacert $CA -b /tmp/auth-admin.txt \
-  -X POST "https://localhost:8443/admins/realms" \
-  -H "Content-Type: application/json" \
-  -d '{
-    "id": "acme.com",
-    "auth_params": {
-      "username_password_params": {"allow_expired_passwords": false}
-    },
-    "session_max_age_seconds": 3600,
-    "session_max_stale_age_seconds": 7200
-  }'
-
-# 3 — Create a user with role CryptoOfficer
-#     Passwords must be hashed: Argon2id(password, salt=base64(SHA-256(username)))
-#     Auth server uses argon2 v0.4.1 defaults: m=4096, t=3, p=1
-HASH=$(python3 - << 'EOF'
-import hashlib, base64
-from argon2 import PasswordHasher
-username, password = "alice", "alice-pass"
-salt = base64.b64encode(hashlib.sha256(username.encode()).digest()).rstrip(b"=")
-ph = PasswordHasher(time_cost=3, memory_cost=4096, parallelism=1, hash_len=32)
-print(ph.hash(password, salt=base64.b64decode(salt + b"==")))
-EOF
-)
-
-curl -s --cacert $CA -b /tmp/auth-admin.txt \
-  -X POST "https://localhost:8443/realms/acme.com/userpass" \
-  -H "Content-Type: application/json" \
-  -d "{
-    \"realm\": \"acme.com\",
-    \"username\": \"alice\",
-    \"password\": \"$HASH\",
-    \"change_password\": false,
-    \"roles\": [\"CryptoOfficer\"],
-    \"domain\": \"acme.com\"
-  }"
-```
-
-Repeat step 3 for each user, adjusting `username`, `password`, `roles`, and optionally
-`domain` (defaults to realm `id` if omitted).
-
-#### Obtain a JWT
-
-```bash
-JWT=$(curl -s --cacert $CA -D - \
-  -X POST "https://localhost:8443/login?realm=acme.com" \
-  -u "alice:alice-pass" \
-  -H "Content-Type: application/json" \
-  -d '{"public_key_pem":null,"totp_code":null}' \
-  | grep -i "set-cookie: _ea_=" \
-  | sed 's/.*_ea_=\([^;]*\).*/\1/' | tr -d '\r')
-
-echo "JWT: $JWT"
-# Inspect claims: echo $JWT | cut -d. -f2 | base64 -d 2>/dev/null | python3 -m json.tool
-```
-
-The JWT is a standard ES256-signed token (or the key type configured in
-`tls_params`). Its payload contains:
-
-```json
-{
-  "sub":    "alice",
-  "iss":    "cosmian-auth-test",
-  "roles":  ["CryptoOfficer"],
-  "as_rid": "acme.com",
-  "exp":    
-}
-```
-
-#### Configure KMS to trust the auth server
-
-The KMS validates JWTs against the auth server's JWKS endpoint
-(`https:///public/jwks`).
-
-```toml
-# kms.toml
-[idp_auth]
-# Format: "issuer,jwks_uri"
-# The issuer string must match the `iss` claim in the JWT.
-jwt_auth_provider = ["cosmian-auth-test,https://localhost:8443/public/jwks"]
-
-[opa]
-opa_url  = "http://localhost:8181"
-opa_mode = "enforcing"
-```
-
-Because the auth server uses a self-signed certificate, start the KMS with the CA cert
-or with `--accept-invalid-certs` (dev only):
-
-```bash
-cargo run --features non-fips --bin cosmian_kms -- \
-  --database-type sqlite \
-  --sqlite-path /tmp/kms-data \
-  --jwt-auth-provider "cosmian-auth-test,https://localhost:8443/public/jwks" \
-  --opa-url http://localhost:8181 \
-  --opa-mode enforcing \
-  --accept-invalid-certs
-```
-
-#### Auth server REST API summary
-
-| Endpoint | Method | Auth | Description |
-|---|---|---|---|
-| `POST /login?realm=_` | Basic auth | — | Login as admin, receive `_ea_` session cookie |
-| `POST /login?realm=` | Basic auth | — | Login as user, receive `_ea_` JWT cookie |
-| `GET /public/jwks` | — | Public | JWKS endpoint (KMS fetches this to validate JWTs) |
-| `GET /public/roles` | — | Public | List of configured role names |
-| `POST /admins/realms` | JSON | Admin session | Create a realm |
-| `POST /admins` | JSON | Admin session | Create a realm-scoped admin account |
-| `POST /realms//userpass` | JSON | Admin session | Create a user with roles + domain |
-| `DELETE /realms//userpass/` | — | Admin session | Delete a user |
-| `GET /public/version` | — | Public | Server version |
-
-### Keycloak
-
-1. Create a realm (e.g. `acme`).
-2. Add a `roles` claim via a **Mapper** of type *User Attribute* or *User Realm Role*.
-3. Add a custom `as_rid` attribute mapper that reads a user attribute `domain`.
-4. The JWKS URI is `https:///realms//protocol/openid-connect/certs`.
-
-```toml
-# kms.toml — KMS side
-[idp_auth]
-jwt_auth_provider = ["https://keycloak.acme.com/realms/acme,https://keycloak.acme.com/realms/acme/protocol/openid-connect/certs"]
-```
-
-### Other OIDC providers (Okta, Auth0, Google)
-
-Any OIDC-compliant provider works as long as it can emit `roles` and `as_rid` (or `as_domain`) in the
-JWT. For providers that do not support custom claims natively, use a token transformation
-step (e.g. Okta hooks, Auth0 rules/actions).
-

-
-## Step 2 — OPA server: deploy and load the Rego policy
-
-### Docker Compose (recommended for production)
-
-```yaml
-# docker-compose.yml
-services:
-  opa:
-    image: openpolicyagent/opa:edge-static-debug
-    ports:
-      - "8181:8181"
-    volumes:
-      - ./test_data/opa/kms.rego:/policies/kms.rego:ro
-    command:
-      - run
-      - --server
-      - --log-level=info
-      - --addr=0.0.0.0:8181
-      - /policies/kms.rego
-```
-
-```bash
-docker compose up -d opa
-```
-
-### Standalone Docker
-
-```bash
-docker run -d --name opa \
-  -p 8181:8181 \
-  -v "$(pwd)/test_data/opa/kms.rego:/policies/kms.rego:ro" \
-  openpolicyagent/opa:edge-static-debug \
-  run --server --log-level=info --addr=0.0.0.0:8181 /policies/kms.rego
-```
-
-### Verify OPA is ready
-
-```bash
-# Health check
-curl http://localhost:8181/health
-
-# Test a CryptoOfficer create request — expect {"result":true}
-curl -s -X POST http://localhost:8181/v1/data/kms/allow \
-  -H "Content-Type: application/json" \
-  -d '{
-    "input": {
-      "user": "alice@acme.com",
-      "user_domain": "acme.com",
-      "roles": ["CryptoOfficer"],
-      "operation": "create",
-      "object_uid": "*",
-      "object_domain": "acme.com",
-      "is_owner": false
-    }
-  }'
-```
-
----
-
-## Step 3 — KMS server: wire JWT auth and OPA
-
-### kms.toml
-
-```toml
-[http]
-hostname = "0.0.0.0"
-port     = 9998
-
-[db]
-database_type = "sqlite"
-sqlite_path   = "/var/lib/kms/data"

-# For Keycloak:
-# jwt_auth_provider = ["https://keycloak.acme.com/realms/acme"]
-
-# ── OPA sidecar ──────────────────────────────────────────────────────────

-| `KMS_OPA_URL` | `http://localhost:8181` | OPA base URL |
-| `KMS_OPA_MODE` | `enforcing` | `exclusive` or `enforcing` |
-
-### cargo run (development)
-
-```bash
-RUST_LOG="cosmian_kms_server=debug" \
-cargo run --features non-fips --bin cosmian_kms -- \
-  --database-type sqlite \

-  --opa-mode enforcing \
-  --accept-invalid-certs
-```
-
----
-
-## Step 4 — Obtain a JWT and call the KMS
-
-### With the Cosmian Authentication Server
-
-The Cosmian Auth Server issues JWTs via a direct login API (cookie-based, not OAuth2
-PKCE). The `ckms login` command **cannot** be used with it. Instead, extract the JWT
-from the `_ea_` cookie and place it in `ckms.toml` directly.
-
-```bash
-CA=/path/to/authentication/server/src/tests/certificates/ec/auth.ca.pem
-
-# Login as alice in realm acme.com — JWT comes back as the _ea_ cookie
-JWT=$(curl -s --cacert $CA -D - \
-  -X POST "https://localhost:8443/login?realm=acme.com" \
-  -u "alice:alice-pass" \
-  -H "Content-Type: application/json" \
-  -d '{"public_key_pem":null,"totp_code":null}' \
-  | grep -i "set-cookie: _ea_=" \
-  | sed 's/.*_ea_=\([^;]*\).*/\1/' | tr -d '\r')
-
-# Inspect the JWT claims (optional)
-echo $JWT | cut -d. -f2 | base64 -d 2>/dev/null | python3 -m json.tool
-
-# Write to ckms.toml
-cat > /tmp/ckms-alice.toml << EOF
-[http_config]
-server_url           = "http://127.0.0.1:9998"
-accept_invalid_certs = false
-access_token         = "${JWT}"
-EOF
-
-# Use it
-cargo run --bin ckms -- -c /tmp/ckms-alice.toml sym keys create -t test-key
-```
-
-### With a standard OIDC provider (Keycloak, Okta, …): `ckms login`
-
-Standard OIDC providers support OAuth2 PKCE. Configure `ckms.toml` with OAuth2
-settings and use `ckms login` to obtain the token via a browser flow:
-
-```toml
-# ckms.toml
-[http_config]
-server_url = "http://localhost:9998"
-
-[http_config.oauth2_conf]
-client_id     = "ckms-client"
-client_secret = ""           # empty for PKCE-only flows
-authorize_url = "https://keycloak.acme.com/realms/acme/protocol/openid-connect/auth"
-token_url     = "https://keycloak.acme.com/realms/acme/protocol/openid-connect/token"
-scopes        = ["openid", "email"]
-```
-
-```bash
-ckms -c ckms.toml login   # opens browser → saves token to ckms.toml
-ckms -c ckms.toml sym keys create
-ckms -c ckms.toml logout
-```
-
-### Development: unsigned JWT (no IdP needed, requires `--features insecure`)
-
-The KMS server must be running with `--features insecure` (skips JWT signature and
-expiry validation). **Never use this in production.**
-
-```bash
-# Build a test JWT for a CryptoOfficer in domain acme.com
-PAYLOAD=$(echo -n '{"sub":"alice","as_rid":"acme.com","roles":["CryptoOfficer"],"iss":"test","exp":9999999999}' \
-  | base64 -w0 | tr '+/' '-_' | tr -d '=')
-JWT="eyJhbGciOiJub25lIn0.${PAYLOAD}."
-
-# Write it to a ckms config
-cat > /tmp/ckms-officer.toml << EOF
-[http_config]
-server_url = "http://127.0.0.1:9998"
-access_token = "${JWT}"
-EOF
-
-# Create a key as CryptoOfficer
-cargo run --bin ckms -- -c /tmp/ckms-officer.toml sym keys create -t test-key
-
-# Create a JWT for a User role
-PAYLOAD=$(echo -n '{"sub":"bob","as_rid":"acme.com","roles":["User"],"iss":"test","exp":9999999999}' \
-  | base64 -w0 | tr '+/' '-_' | tr -d '=')
-JWT_USER="eyJhbGciOiJub25lIn0.${PAYLOAD}."
-cat > /tmp/ckms-user.toml << EOF
-[http_config]
-server_url = "http://127.0.0.1:9998"
-access_token = "${JWT_USER}"
-EOF
-
-# Locate the key (User can read attributes) — allowed
-cargo run --bin ckms -- -c /tmp/ckms-user.toml locate --tag test-key
-
-# Destroy the key as User — denied by OPA (destroy ∉ user_ops)
-cargo run --bin ckms -- -c /tmp/ckms-user.toml sym keys destroy --key-id 
-```

-## Role reference
-
-| Role | Domain scope | Allowed KMIP operations |
-|---|---|---|
-| `SuperAdmin` | All domains | All |
-| `DomainAdmin` | Own domain | All |
-| `CryptoOfficer` | Own domain | `create`, `create_key_pair`, `import`, `get`, `export`, `locate`, `get_attributes`, `set_attribute`, `modify_attribute`, `delete_attribute`, `add_attribute`, `activate`, `revoke`, `archive`, `recover`, `destroy`, `rekey`, `rekey_key_pair` |
-| `Auditor` | Own domain | `locate`, `get`, `get_attributes`, `list_access`, `query_access`, `mac_verify` |
-| `User` | Own domain | `encrypt`, `decrypt`, `sign`, `verify`, `mac`, `mac_verify`, `derive_key`, `locate`, `get_attributes` |

-## OPA input document (reference)
-
-The KMS sends this JSON to `POST /v1/data/kms/allow` on every request:
-
-```json
-{
-  "input": {
-    "user":          "alice@acme.com",
-    "user_domain":   "acme.com",
-    "roles":         ["CryptoOfficer"],
-    "operation":     "create",
-    "object_uid":    "*",
-    "object_domain": "acme.com",
-    "is_owner":      false
-  }
-}
-```
-
-| Field | Source | Notes |
-|---|---|---|
-| `user` | JWT `sub` | Authenticated identity |
-| `user_domain` | JWT `as_rid` (or legacy `as_domain`) | Empty `""` for non-JWT auth |
-| `roles` | JWT `roles` | Empty `[]` for non-JWT auth → fail-closed |
-| `operation` | KMIP operation tag | Lowercase snake_case (e.g. `"create"`, `"get_attributes"`) |
-| `object_uid` | Target object UID | `"*"` for object-less operations |
-| `object_domain` | `objects.domain` column | Equals `user_domain` for object-less operations |
-| `is_owner` | `user == object.owner` | Always grants access regardless of role |

-## Debugging access denials
-
-### Query the OPA reason endpoint
-
-```bash
-curl -s -X POST http://localhost:8181/v1/data/kms/reasons \
-  -H "Content-Type: application/json" \
-  -d '{
-    "input": {
-      "user": "alice@acme.com",
-      "user_domain": "acme.com",
-      "roles": ["CryptoOfficer"],
-      "operation": "destroy",
-      "object_uid": "key-123",
-      "object_domain": "acme.com",
-      "is_owner": false
-    }
-  }'
-# {"result":["crypto_officer"]}  → CryptoOfficer allows destroy
-# {"result":["denied"]}          → no rule matched
-```
-
-### Enable trace logging on the KMS
-
-```bash
-RUST_LOG="cosmian_kms_server=trace" cargo run --bin cosmian_kms -- ...
-```
-
-Look for:
-- `cosmian_kms_server::middlewares::ensure_auth` — JWT extraction and role/domain parsing
-- `cosmian_kms_server::core::retrieve_object_utils` — OPA input document and decision
-- `cosmian_kms_server::core::opa::client` — HTTP round-trip timing and result
-
-### Enable OPA decision logging
-
-Add `--log-level=info` to OPA's startup flags (default in the Docker Compose service).
-OPA prints a structured JSON decision log for every query.
-
----
-
-## Common problems
-
-| Symptom | Likely cause | Fix |
-|---|---|---|
-| `401 Unauthorized` | JWT missing or signature invalid | Check KMS `--jwt-auth-provider` issuer and JWKS URI |
-| `403 Forbidden` — OPA deny | Role not in JWT or cross-domain | Check `roles` claim; verify `as_rid` realm matches `object_domain` |
-| `403 Forbidden` — OPA unreachable | OPA not running or wrong port | Check `KMS_OPA_URL`; run `curl http://localhost:8181/health` |
-| `403 Forbidden` — Native KMS deny | Mode 3: no DB grant exists | Add grant with `ckms access-rights grant`, or switch to Mode 2 |
-| Empty `roles: []` in OPA input | Using mTLS or API-token auth | Roles only come from JWT; switch auth method or write a custom Rego rule |
-| `roles` claim not in JWT | IdP not configured to emit it | Add a `roles` claim mapper in Keycloak / Auth0 / Okta |

-// (against a Vite preview backed by a real KMS), because all KMS API calls are

-// The key insight: /access/create is mocked to return 401, so the mTLS cert
-// auto-login path in App.tsx is neutralised — the app never considers the user
-// already authenticated, and the login page always renders.
+// In CI the UI is always built with VITE_DEV_MODE=true, which makes
+// fetchAuthMethods() return [] immediately without making a network call.
+// In that mode the login page is never rendered, so these mocks are ineffective.

Subject: [PATCH 167/181] fix(server_database): execute create_crls table in
 SQLite init transaction

The create_crls SQL query was fetched but never executed in the SQLite
bootstrap transaction, causing the crls table to never be created on
SQLite databases.

Also regenerate log-reference.md to include new OPA and JWT log entries
added in this branch.

 - Add OPA (Open Policy Agent) RBAC middleware integration with three modes: disabled, exclusive, enforcing
 - Add `--opa-url` and `--opa-mode` CLI flags (env vars `KMS_OPA_URL`, `KMS_OPA_MODE`) to configure the OPA sidecar
+- Add startup validation: `--opa-mode exclusive` or `--opa-mode enforcing` now fails with a clear error when `--opa-url` is not set (the server previously silently ignored the mode setting)
+- Add KMIP-GO compliance tests for `CreateSplitKey` (§4.38) and `JoinSplitKey` (§4.39): share metadata assertions, full split-then-join roundtrip, threshold enforcement, and Query operation advertisement (`split_key_test.go`)
 - Add `domain` column to the objects table across all database backends (SQLite, PostgreSQL, MySQL, Redis-findex) for domain-scoped access control
 - Add `OpaClient` HTTP client with fail-closed design (deny on any transport/parse error)
 - Wire OPA authorization into `user_has_permission()` with mode-dependent behavior:

+// ─── Regression — OPA enforcing mode does not deadlock CO ceremony ────────────
+
+/// **BUG REGRESSION**: CO ceremony was impossible in OPA enforcing mode.
+///
+/// ## Root cause
+///
+/// In `user_has_permission()`, the OPA Gate 1 bypass for "native COs" used
+/// `kms.is_crypto_officer(user)`, which returns **false** for ceremony candidates
+/// who have not yet activated.  This created a chicken-and-egg deadlock:
+///
+/// - Ceremony candidates need to `Get` peer shares (held by other COs) in order to
+///   call `JoinSplitKey` and complete the ceremony.
+/// - Before ceremony completion, `is_crypto_officer()` → false → OPA Gate 1 runs.
+/// - OPA sees `roles = []` (mTLS auth, no JWT) and `is_owner = false` (peer share)
+///   → **deny** → ceremony blocked.
+///
+/// ## Fix
+///
+/// Extend `is_native_co` in `user_has_permission` to also include users listed in
+/// `crypto_officer.users`, regardless of ceremony completion.  These users bypass
+/// OPA Gate 1 (which is designed for JWT-role enforcement) but still go through the
+/// legacy gate (DB ownership + grant checks).

- Display: each variant formats to expected lowercase string
- Default: OpaMode::default() == Disabled (backward-compat invariant)
- Round-trip: Display -> from_str is identity for every variant

- All 7 field names serialize with correct snake_case JSON keys
- is_owner: true/false serialize as JSON booleans (not strings)
- roles serializes as JSON array
- Object-less op has object_uid='*' and is_owner=false

- Default context is zero-privilege (empty roles, None domain)
- Outside task scope returns default (no panic)
- Inside OPA_USER_CONTEXT.scope() returns the scoped value
- Scope does not leak after future completes
- Nested scopes: inner value visible inside, outer visible outside

- OpaClient::new constructs the correct /v1/data/kms/allow URL
- Trailing slash on base URL is stripped before path append
- Custom path prefix (non-default OPA mount) is preserved
- OpaResponse: result=true, result=false, missing key, null value

- Object-less op: uid='*', object_domain=user_domain, is_owner=false
- Object-less op with no user domain: both domain fields default to empty string
- Owner: is_owner=true, uid and domain taken from ObjectWithMetadata
- Non-owner: is_owner=false
- Cross-domain: object_domain comes from stored object, not user_domain
- Operation names are lowercase snake_case (create, get, get_attributes...)
- Roles are passed through unchanged
- User identity is preserved verbatim

- Default has no URL and mode='disabled'
- Default mode string parses as OpaMode::Disabled

- handle_auth_verifier: domain, roles, sub-as-username, missing header, absent domain
- handle_jwt: domain, roles, sub fallback, email preferred over sub, absent domain

- jwt_token_auth.rs: remove panicking actix_identity::Identity::extract call;
  handle_jwt reads directly from Authorization: Bearer header
- server_params.rs: add opa_params to manual Debug impl (was missing, triggered
  Clippy manual_debug lint)

- mode_exclusive_auditor_wrong_domain
- mode_exclusive_user_wrong_domain
- mode_enforcing_wrong_domain
- mode_exclusive_super_admin_cross_domain (positive: SA can cross domains)
Total OPA vectors: 15

 - Extend `setup_auth_server_for_opa` to provision 3 users: `kms-opa-officer` (CryptoOfficer, kms-opa-test), `kms-opa-user` (User, kms-opa-test), `kms-opa-other-officer` (CryptoOfficer, kms-opa-other); store extra JWTs in `KMS_TEST_OPA_USER_ROLE_JWT` / `KMS_TEST_OPA_OTHER_DOMAIN_JWT`
 - Restructure `setup_auth_server_for_opa` to use separate admin (`cookie_store=true`) and login (cookieless) clients, preventing admin session cookie from being overwritten by user logins
 - Add 3 more OPA test vectors (`mode_exclusive_auditor_destroy_denied`, `mode_exclusive_auditor_get_attributes_allowed`, `mode_exclusive_domain_admin_wrong_domain`) with JWT-based Auditor and DomainAdmin identities; now 11 OPA vectors total, all passing
+- Add 4 multi-tenant isolation test vectors completing the cross-domain isolation matrix for all five RBAC roles:
+    - `mode_exclusive_auditor_wrong_domain`: Auditor (kms-opa-test) denied `GetAttributes` on a key owned by kms-opa-other — same_domain fails even for read-only metadata ops
+    - `mode_exclusive_user_wrong_domain`: User (kms-opa-test) denied `GetAttributes` on a key owned by kms-opa-other — domain boundary blocks even the least-privileged role
+    - `mode_enforcing_wrong_domain`: CryptoOfficer (kms-opa-other) denied `Get` on a kms-opa-test key in enforcing mode — domain isolation is not exclusive-mode-only
+    - `mode_exclusive_super_admin_cross_domain`: SuperAdmin allowed `Get` and `Destroy` across domain boundaries — proves only the designated top role bypasses `same_domain`; now 15 OPA vectors total
 - Extend `setup_auth_server_for_opa` to provision 5 users with per-user `domain` field: `kms-opa-officer` (CryptoOfficer, kms-opa-test), `kms-opa-user` (User, kms-opa-test), `kms-opa-auditor` (Auditor, kms-opa-test), `kms-opa-domain-admin-other` (DomainAdmin, kms-opa-other), `kms-opa-other-officer` (CryptoOfficer, kms-opa-other); store JWTs in `KMS_TEST_OPA_AUDITOR_JWT`, `KMS_TEST_OPA_DOMAIN_ADMIN_OTHER_JWT`
 
 ## Bug Fixes
 
 - `UserClaim` JWT deserialization: add `#[serde(default)]` to `aud` field so JWTs without an `aud` claim (e.g. from Cosmian auth server) are accepted instead of failing with "missing field `aud`"
 - JWT middleware: fall back to `sub` claim when `email` is absent, enabling compatibility with Cosmian auth server JWTs that use `sub` for the username
+- JWT middleware (`handle_jwt`): remove panicking `actix_identity::Identity::extract` call; the JWT bearer-token middleware reads directly from the `Authorization: Bearer` header — session cookie auth is handled by the dedicated `SessionAuth` middleware and must not be mixed into the OIDC JWT path
 - OPA denied test servers: merge `exclusive_denied` and `enforcing_denied` into a single shared `ONCE_VECTOR_OPA_DENIED` singleton to avoid concurrent macOS Keychain PKCS#12 loading failures (`OSStatus -26276`) when both servers start in parallel
 - OPA denied test servers: set opa-mode-specific `sqlite_path`, `root_data_path`, and `socket_server_start = false` to prevent port/file conflicts between concurrent cert-auth test servers
 - Auth server provisioning: use `drop()` instead of `let _ =` on HTTP responses to avoid `let_underscore_drop` Clippy lint
@@ -65,3 +71,4 @@
 - Fix auth server provisioning: set `domain` field on each userpass record to the realm ID so the JWT `as_domain` claim is emitted and OPA `same_domain` checks work correctly
 - Fix `enforce_create_permission`: honor `crypto_officer.users` and `default_username` for the `Create` right even when OPA is active, so KMS-native CryptoOfficers (e.g. split-key ceremony participants) can still create keys; OPA remains the authoritative gatekeeper for all other users
 - OPA test provisioning: send plaintext passwords to the auth server's `create_userpass` endpoint (the server now computes the Argon2id hash itself) and drop the obsolete `argon2`/`sha2` dev-dependencies
+- Add 5 unit tests for `handle_auth_verifier` (full pipeline: HTTP `Authorization` header → `AuthenticatedUser.domain` + `.roles`) and 5 unit tests for `handle_jwt` (full pipeline: Authorization header → `AuthenticatedUser.domain` + `.roles` + username resolution) in `crate/server/src/middlewares/`; these are the definitive proof that `domain` and `roles` survive the middleware pipeline without being dropped

+## Alternatives Considered
+
+### Embedded OPA Go library via FFI
+
+- **ALT-001 Description**: Compile OPA as a Go shared library and call it from Rust via FFI.
+- **ALT-002 Rejection Reason**: Significant build complexity; cross-language memory management;
+  not idiomatic in Rust; breaks the FIPS build which does not allow arbitrary C/Go linkage.
+
+### Role enum in `kms.toml`
+
+- **ALT-003 Description**: Define allowed roles as an enum or list in the server configuration file.
+- **ALT-004 Rejection Reason**: Hard-codes role vocabulary in KMS config; operators cannot rename
+  roles without a KMS change and restart. Defeats the "dynamic roles" requirement.
+
+### Static role mapping in database
+
+- **ALT-005 Description**: Store role-to-permission mappings in the KMS database (e.g. a `roles` table).
+- **ALT-006 Rejection Reason**: Same problem as enum-in-config; role changes require a database
+  migration or admin API call; no independent audit log; no human-readable policy file.
+
+### Casbin (Rust-native)
+
+- **ALT-007 Description**: Use the Rust `casbin` crate for policy-based access control.
+- **ALT-008 Rejection Reason**: Smaller ecosystem; less operator familiarity; no native audit-log
+  integration comparable to OPA's; would still require a sidecar model for live policy reload.
+
+### OPA bundled as in-process Wasm
+
+- **ALT-009 Description**: Compile the Rego policy to Wasm and evaluate it in-process.
+- **ALT-010 Rejection Reason**: Experimental OPA Wasm support does not cover the Data API;
+  cannot be updated without redeployment; no audit log support.
+
+## Implementation Notes
+
+- **IMP-001**: The `OpaClient` uses a 5-second HTTP timeout with fail-closed semantics.
+  OPA must be co-located (same host or pod) to avoid latency issues.
+- **IMP-002**: Domain is stamped on every newly created object from the creator's JWT
+  `as_domain` / `as_rid` claim via `OpaUserContext`.  Existing objects upgraded from
+  pre-OPA KMS versions will have an empty domain string; the Rego policy must handle
+  `object_domain == ""` gracefully (e.g., allow owner access regardless of domain).
+- **IMP-003**: The `domain` column is added to all database backends (SQLite, PostgreSQL,
+  MySQL, Redis-findex) via `ALTER TABLE ADD COLUMN domain TEXT NOT NULL DEFAULT ''`.
+  This migration is applied automatically on server startup.
+- **IMP-004**: `enforce_create_permission` explicitly preserves KMS-native CryptoOfficer
+  access (`crypto_officer.users` list) for the `Create` right even when OPA is active,
+  so split-key ceremony participants retain their ability to create key shares.
+- **IMP-005 Success criteria**: All 15 OPA test vectors in `test_data/vectors/opa/` pass,
+  covering all five roles × disabled/exclusive/enforcing modes × allow and deny paths.

## Problem (SPIRE / kmip-go limitation)

https://github.com/spiffe/spire/pull/7235#discussion_r3829548963 documented that
the Eviden KMS did not expose a way for SPIRE's UpstreamAuthority plugin to
specify the TTL (validity period) when asking the KMS to sign an intermediate CA
CSR.  The workaround was to rely on the KMS server's global certificate_expiry_days
setting and acknowledge the PreferredTtl hint as lost.

## Root cause

The KMS already honours the 'requested_validity_days' Cosmian vendor attribute on
CSR-based Certify requests (build_and_sign_certificate reads it at line 75 before
any subject-type branch).  The gap was:
  1. No test proved end-to-end that the vendor attribute was applied correctly
     for CSR-based requests (only subject-DN-based requests were tested).
  2. github.com/Cosmian/kmip-go's Certify() had no ttlDays parameter, so
     callers had no way to pass requested_validity_days.

## Fix

### crate/server/src/tests/crl_tests.rs — 2 new regression tests
- test_certify_from_csr_with_requested_validity_days
- test_certify_from_csr_default_validity

### github.com/Cosmian/kmip-go (commit e01d034)

 - Add KMIP-GO compliance tests for `CreateSplitKey` (§4.38) and `JoinSplitKey` (§4.39): share metadata assertions, full split-then-join roundtrip, threshold enforcement, and Query operation advertisement (`split_key_test.go`)
 - Add `domain` column to the objects table across all database backends (SQLite, PostgreSQL, MySQL, Redis-findex) for domain-scoped access control
 - Add `OpaClient` HTTP client with fail-closed design (deny on any transport/parse error)
+- Add support for CSR-based Certify TTL: the `requested_validity_days` vendor attribute is now honoured on CSR-based `Certify` requests (the `build_and_sign_certificate` path already read it; this release adds regression tests and a matching `ttlDays int` parameter to `github.com/Cosmian/kmip-go`'s `Certify()` function, closing the SPIRE / kmip-go limitation documented at )
 - Wire OPA authorization into `user_has_permission()` with mode-dependent behavior:
     - Exclusive: OPA is the sole decision maker
     - Enforcing: both OPA and legacy KMS permission logic must allow

 ## Testing
 
+**AI agent mandatory rule: Every new Rust module or feature introduced in a PR MUST include all four test layers below before the PR is considered complete. This rule is non-negotiable and cannot be skipped or deferred.**
+
+### 4 mandatory test layers
+
+| Layer | Location | Runs with | Purpose |
+|-------|----------|-----------|---------|
+| **Unit** | `#[cfg(test)]` at bottom of same file | `cargo test -p  ` | Isolate a single function / algorithm correctness |
+| **DB persistence** | `crate/server_database/src/tests/` shared helper called from each backend | `cargo test -p cosmian_kms_server_database` | Verify upsert/read/max/list round-trips for every new DB method |
+| **Functional** | `crate/server/src/tests/_tests.rs` | `cargo test -p cosmian_kms_server _tests` | End-to-end operation through `KMS::` API; covers happy paths, error cases, format variants |
+| **Security/non-regression** | Same file as functional or a dedicated `_security.rs` | Same runner | Replay of every security invariant: enforcement, boundary values, restart monotonicity, invalid inputs |
+
+### Mandatory content per layer
+
+**Unit tests** (file: same file as the code, `#[cfg(test)]` submodule):
+
+- Cover every public function's happy path.
+- Cover at least one error case per fallible function.
+- For any cryptographic primitive: verify round-trip (encode → decode → compare).
+- For any ASN.1 encoding: assert the DER tag byte explicitly (e.g., `0x0A` for ENUMERATED).
+
+**DB persistence tests** (shared helper, called from all backends):
+
+- Empty table → query returns `None` / `[]`.
+- Single insert → retrieve returns the exact bytes inserted.
+- Multiple inserts → aggregate query (`MAX`, `COUNT`, `LIST`) returns the correct result.
+- Upsert replaces previous value (not duplicates).
+- Unknown key → returns `None`, no panic.
+- Monotonicity invariant: `seed = max(ts, db_max + 1) > db_max` holds.
+
+**Functional tests** (new file `crate/server/src/tests/_tests.rs`):
+
+- Use `make_kms()` / `test_kms()` for in-process SQLite tests (no network).
+- Cover the full lifecycle: create → operate → verify state.
+- Test all output formats (DER, PEM, JSON) when applicable.
+- Test that the result is persisted and retrievable from cache/DB.
+- Test that auto-triggers work (e.g., revoke → CRL auto-refresh).
+- Test REST endpoint responses: 200 with correct MIME, 404 when not found.
+
+**Security/non-regression tests** (same file, clearly labeled):
+
+- Every cryptographic invariant the code comments claim must be asserted.
+- Every security check that was added (e.g., keyUsage enforcement) must have a test that fires the error path.
+- All enumeration values of any KMIP enum must be exercised (e.g., all `RevocationReasonCode` values).
+- Restart-invariant properties: simulate what happens after `KMS::instantiate()` is called a second time on the same DB.
+
+### Reference implementation: CRL feature
+
+`crate/server/src/tests/crl_tests.rs` is the canonical reference for this 4-layer pattern:
+
+```text
+crl.rs (unit)                  ← test_build_empty_crl, test_build_crl_with_entries,
+                                  test_crl_reason_asn1_tag_is_enumerated
+permissions_test.rs (DB)       ← crl_persistence() — empty, upsert, max, list, replace
+crl_tests.rs (functional)      ← 14 tests covering all paths, endpoints, formats
+crl_tests.rs (security)        ← cRLSign enforcement, reason code mapping, restart monotonicity
+```
+
+Study this file before implementing tests for any new cryptographic feature.
+
+### Template for new functional test file
+
+```rust
+//! Tests for the  feature.
+//!
+//! | Category | Tests |
+//! |----------|-------|
+//! | Unit | in `crate/crypto/src/openssl/.rs` |
+//! | DB | in `crate/server_database/src/tests/permissions_test.rs` |
+//! | Functional |  |
+//! | Security |  |
+
+#![allow(clippy::unwrap_used, clippy::expect_used)]

+
+async fn make_kms() -> KResult> {
+    init_openssl_providers_for_tests();
+    Arc::new(KMS::instantiate(Arc::new(ServerParams::try_from(https_clap_config())?)).await?)
+        .map(Ok)  // adjust to project idiom
+}
+
+// ── Functional tests ──────────────────────────────────────────────────────────
+#[tokio::test]
+async fn test__happy_path() -> KResult<()> { ... }
+
+// ── Security / non-regression tests ───────────────────────────────────────────
+#[tokio::test]
+async fn test__rejects_invalid_input() -> KResult<()> { ... }
+```
+
+### Rules
+
 - Unit tests go in a `#[cfg(test)]` submodule at the bottom of the same file.
 - Use `use super::*;` in test modules.
 - Run targeted tests: `cargo test -p  ` — not the full suite.
+- **Never mark a test `#[ignore]` to make the suite green.** If a test requires infrastructure (DB, network), annotate it with the reason: `#[ignore = "Requires running PostgreSQL"]`.
+- Register every new test module in `crate/server/src/tests/mod.rs`.

+## Features
+
+- **PKI / Auto-inject CRL Distribution Point into issued certificates**: the Certify
+  operation now automatically adds a `crlDistributionPoints` extension (RFC 5280 §4.2.1.13)
+  pointing to the KMS public CRL endpoint (`{kms_public_url}/public/certificates/{issuer_id}/crl`)
+  when `kms_public_url` is configured, the certificate is not self-signed, and neither the
+  subject nor the user-supplied extension config already provides a CDP. Self-signed certs
+  continue to receive `id-ce-noRevAvail` (RFC 9608) instead. Re-certifications that already
+  carry a CDP are not modified.
+
+- **PKI / CRL generation**: add X.509 v2 CRL generation per RFC 5280 §5.
+  New REST endpoint `GET /certificates/{issuer_id}/crl` returns a signed CRL
+  (DER or PEM) containing all revoked certificates issued by the given CA.
+  New CLI command `ckms certificates generate-crl`. Web UI support via
+  Certificates → Certs → Generate CRL.
+
+- **PKI / Public CRL Distribution Point**: new unauthenticated endpoint
+  `GET /public/certificates/{issuer_id}/crl` serves pre-signed CRL DER bytes
+  from an in-memory cache so that any PKI relying party (browser, TLS stack,
+  OCSP client) can fetch CDP URIs without KMS credentials (RFC 5280 §3).
+  The cache is populated every time the authenticated CRL generation endpoint
+  is called. Returns HTTP 404 with a diagnostic message until the cache is primed.
+
+- **PKI / Extended RevocationReasonCode coverage**: `RevocationReasonCode` now
+  includes `CertificateHold` (0x8000_0001), `RemoveFromCRL` (0x8000_0002), and
+  `AaCompromise` (0x8000_0003) as KMIP vendor-extension codes (8XXXXXXX range per
+  KMIP 2.1 §11.48). These correspond to RFC 5280 §5.3.1 reason codes absent from
+  the KMIP standard set. `kmip_reason_to_crl_reason()` is now fully exhaustive.
+
+- **PQC key export as Raw bytes**: PQC keys (ML-KEM, ML-DSA, SLH-DSA) stored
+  internally as PKCS#8/SPKI can now be exported with `KeyFormatType::Raw`.
+  The server performs on-the-fly PKCS#8→Raw conversion using OpenSSL's
+  `EVP_PKEY_get_raw_*_key` APIs. Compliant with KMIP v3.0 CSD01 which defines
+  no Transparent key structures for PQC algorithms.
+
+## Bug Fixes
+
+- **PKI / CRL freshness**: `verify_crls()` now enforces the `nextUpdate` field
+  (RFC 5280 §6.3 §5.1.2.5). Expired CRLs are now hard-rejected with a descriptive
+  error message instead of being silently accepted.
+
+- **PKI / HTTP CRL signature enforcement**: CRLs fetched from `http://` or `https://`
+  URLs whose signature cannot be verified against any issuer in the chain are now
+  rejected with a hard error (previously only a warning). File-path CRLs keep the
+  warn-and-continue behavior (trusted local delivery).
+
+- **Revocation persistence**: fix revocation reason not being persisted in object
+  attributes when revoking a certificate or key. The reason is now stored in both
+  the external attributes and the object's own attributes.
+
+- **CRL cache**: file-path CRLs are no longer cached in memory. Unlike HTTP CRLs,
+  file reads are cheap and the file may be updated after a revocation triggers CRL
+  regeneration. This ensures that `Validate` always picks up fresh CRL data from disk.
+
+- **CRL validation with file:// URIs**: `file://` URIs in certificate CDP extensions
+  were incorrectly treated as web URLs and skipped during CRL validation. They are now
+  correctly converted to local filesystem paths via `url.to_file_path()`.
+
+- **TTLV normalizer: AttributeValue collapse for structured types**: fix KMIP 1.4
+  `RevocationReason` deserialization failure caused by the TTLV post-serialization
+  normalizer incorrectly collapsing single-child `AttributeValue(Structure[...])` nodes
+  into bare scalar values. The normalizer's "type wrapper" collapse (step 8) is now
+  limited to same-tag wrappers only; the `AttributeValue` case is handled exclusively
+  by step 2b which respects TYPE_TAGS boundaries.
+
+- **CORS / Web UI**: when `cors_allowed_origins` is not explicitly configured, `kms_public_url`
+  is now automatically included in the in-RAM CORS allow-list alongside the standard loopback
+  defaults. This fixes the Web UI being inaccessible after upgrading from 5.16.x to 5.22+ when
+  `kms_public_url` was set but `cors_allowed_origins` was absent from the TOML config.
+  The configuration wizard already added `kms_public_url` to generated configs; this change
+  closes the gap for hand-written configuration files. Explicit `cors_allowed_origins` lists
+  are used verbatim — `kms_public_url` is not merged in.
+
+## Documentation
+
+- **PKI / pki.md**: added Delta CRLs (RFC 5280 §5.4) to the "Not supported" section.
+
+## Testing
+
+- **Test data / certificate fixtures**: regenerated `test_data/certificates/csr/intermediate.crt`,
+  `leaf.crt`, `leaf.p12`, and `intermediate.p12` without a CRL Distribution Point extension.
+  The prior versions embedded an expired CDP URL (`https://package.cosmian.com/kms/crl_tests/…`)
+  which caused test failures once CRL freshness enforcement (P1.1) was added.
+  Updated `test_data/certificates/openssl/ext.cnf` `[v3_ca]` section to use an LDAP CRL DP
+  (skipped by `verify_crls` which only fetches HTTP/HTTPS URLs), so certify-with-extensions
+  tests continue to verify that CDP extensions are properly embedded without triggering an
+  expired-CRL error.
+
+- **Validate / CRL unreachable soft-fail**: `verify_crls` now catches
+  `KmsError::ClientConnectionError` (network/DNS failure fetching a CRL) and
+  continues with a warning instead of propagating a 500. Hard errors (expired
+  CRL, explicit revocation, bad signature) still propagate as before. This
+  ensures that test certificates with a non-live CRL DP (e.g. `http://crl.example.com/…`)
+  do not break the Validate operation.
+
+- **Validate / RFC 5280 §6.3 compliance**: `validate.rs` now catches all `verify_crls` errors
+  and re-maps them as `KmsError::Certificate` rather than letting `ServerError` variants
+  propagate as a 500. An expired or unverifiable CRL correctly surfaces as a certificate
+  chain validation failure (consistent with existing revocation-fail behavior).
+
+- **CRL validation lifecycle**: end-to-end test that creates a CA, issues a cert
+  with `crlDistributionPoints=URI:file://...`, validates the cert (happy path),
+  revokes it, regenerates the CRL, then validates again (expects failure).
+
+- **PQC export Raw roundtrip**: generates PQC key pairs (ML-DSA-44, ML-KEM-768,
+  SLH-DSA-SHA2-128s), exports as Raw and as PKCS#8, locally converts PKCS#8→Raw,
+  and asserts byte-equality between the two paths.
+
+- **Vector: CRL validation lifecycle** (`test_data/vectors/fips/kmip_operations/crl_validation_lifecycle/`):
+  16-step regression vector exercising full CRL validation with dynamic file:// CDP URIs,
+  including `AllocTempFile`, `GenerateCrl`, and `{{hex:variable}}` template substitution.
+
+- **Vector: ML-DSA-44 export Raw** (`test_data/vectors/fips/asymmetric/ml_dsa_44_export_raw/`):
+  regression vector for PQC key export with `KeyFormatType::Raw`.
+
+- **Vector: ML-KEM-768 export Raw** (`test_data/vectors/fips/asymmetric/ml_kem_768_export_raw/`):
+  regression vector for PQC key export with `KeyFormatType::Raw`.
+
+- **Vector runner extensions**: added `AllocTempFile` pseudo-operation, `GenerateCrl` REST
+  operation, and `{{hex:variable}}` template substitution to the vector runner framework.
+
+## Refactor
+
+- **`crate/crypto`**: replace direct dependency on `foreign-types-shared 0.1` with
+  `foreign-types 0.3` (the crate that re-exports `ForeignType`/`ForeignTypeRef` publicly).
+  `foreign-types-shared` is an internal implementation detail of `foreign-types`; depending
+  on it directly was an inadvertent coupling to an internal sub-crate.
+
+- **CRL RFC 5280 integration tests** (`crate/test_kms_server/src/crl_tests.rs`): added 7
+  new tests covering all RFC 5280 §5 CRL requirements:
+    - `test_crl_partial_revocation_exact_count`: 5 certs issued, 3 revoked — asserts count = 3.
+    - `test_crl_cross_ca_isolation`: cert issued by CA-B and revoked must not appear in CA-A's CRL.
+    - `test_crl_all_revocation_reason_codes`: all 7 RFC 5280 §5.3.1 reason codes each produce one CRL entry.
+    - `test_crl_deactivated_and_compromised_states`: certs in both KMIP Deactivated and Compromised states appear in the CRL.
+    - `test_crl_incremental_generation_unique_crls`: successive CRL generations produce different DER bytes (CRL Number increments).
+    - `test_crl_validity_period`: `nextUpdate - thisUpdate` matches the requested `validity_days` (±1 day tolerance) for 1, 7, and 30 days.
+    - `test_crl_required_extensions_aki_and_number`: CRL carries OIDs 2.5.29.35 (`AuthorityKeyIdentifier`) and 2.5.29.20 (`CRLNumber`) per RFC 5280 §5.2.1 and §5.2.3.
+  Added `x509-parser` as a dependency of `test_kms_server` for DER-level CRL extension inspection.
+
+- **CRL / AKI FIPS compatibility**: `add_aki_extension` in `crate/crypto/src/openssl/crl.rs` now
+  builds the Authority Key Identifier extension manually (RFC 5280 §5.2.1) instead of using
+  `X509V3_EXT_nconf_nid` with `keyid`/`keyid:always`. The old approach called `EVP_sha1()` when
+  the issuer certificate lacked a `subjectKeyIdentifier` extension, which fails under the FIPS
+  provider (SHA-1 is not FIPS-approved for new use). The replacement uses `openssl::sha::Sha1`
+  (low-level C interface, bypass the provider mechanism) to hash the issuer's SPKI DER, and
+  encodes the AKI DER structure directly — making CRL generation FIPS-safe for all issuer
+  certificate types. Fixes `test_crl_required_extensions_aki_and_number` failing on all FIPS DB
+  backends in CI.
+
+- **CRL / Windows file:// URI fix**: `test_crl_validation_lifecycle` and the
+  `crl_validation_lifecycle` vector now use cross-platform file:// URIs when embedding
+  `crlDistributionPoints` in test certificates. On Windows, raw paths like `C:\path\file.pem`
+  produced an invalid `file://C:\path\file.pem` URI (OS error 123). The fix converts paths to
+  the standard `file:///C:/path/file.pem` form via the new `path_to_file_uri` helper. The
+  `AllocTempFile` vector pseudo-step now automatically exposes `{capture_as}_url` alongside
+  `{capture_as}` for use in manifest templates. Fixes `crl_tests::test_crl_validation_lifecycle`
+  and `vector_runner::tests::test_vec_crl_validation_lifecycle` on Windows CI.
+
+- **`crate/test_kms_server`**: remove redundant direct dependency on `cosmian_kms_crypto`.
+  The crate is already reachable via `cosmian_kms_server` → `cosmian_kms_server_database` →
+  `reexport::cosmian_kms_crypto`. Replaced with a direct dep on `cosmian_kms_server_database`
+  and updated import paths accordingly.
+
+- **OpenAPI / Swagger**: add `GET /certificates/{issuer_id}/crl` endpoint with `Certificates`
+  tag, path/query parameters, and DER/PEM response schemas.
+
+## Bug Fixes (PR #987 review)
+
+- **crl.rs: format parameter validation**: the `format` query parameter is now validated;
+  non-`"der"` / non-`"pem"` values return HTTP 400 `Invalid Request` instead of silently
+  defaulting to DER. ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **crl.rs: Last-Modified header format**: the `Last-Modified` response header now uses
+  RFC 7231 IMF-fixdate format (e.g. `Sun, 06 Nov 1994 08:49:37 GMT`) instead of an
+  ISO 8601 timestamp. ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **validate.rs: misleading CRL comment**: the inline comment incorrectly stated that a
+  missing or expired CRL must be treated as a revocation failure (hard-fail). It now correctly
+  describes the soft-fail behavior already implemented in `verify_crls()`.
+  ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **vector_runner: Windows path JSON-escaping**: `load_request_json` now JSON-escapes
+  captured placeholder values (`\` → `\\`, `"` → `\"`, control chars) before substituting
+  them into JSON template strings. On Windows, temp-file paths like
+  `C:\Users\…\kms_vector_0.pem` contained unescaped backslashes that made
+  `serde_json::from_str` fail with "invalid escape". This was the root cause of the
+  `vector_runner::tests::test_vec_crl_validation_lifecycle` failure on Windows CI
+  (`job/80099022383`). ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **build_certificate.rs: DER length overflow**: `encode_der_length` previously silently
+  truncated lengths > 65535 bytes. It now returns `KResult<()>` and propagates an
+  `InvalidRequest` error for oversized CDP URIs. ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **generate_crl.rs: CRL Number monotonicity across server restarts** (RFC 5280 §5.2.3): the
+  CRL sequence counter was previously seeded only from the UTC Unix timestamp on every startup.
+  After restart the new seed could be lower than previously issued CRL Numbers stored in the
+  database, violating RFC 5280 §5.2.3 ("subsequent CRLs MUST have a larger CRL number"). Fix:
+  - Added `get_max_crl_number()` to the `PermissionsStore` trait and all four backends
+    (SQLite, PostgreSQL, MySQL, Redis).
+  - `KMS::instantiate` now reads the highest stored CRL Number from the DB and seeds the
+    counter as `max(unix_timestamp, db_max + 1)`, guaranteeing strict monotonicity across
+    server restarts. ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **generate_crl.rs: cRLSign keyUsage not enforced** (RFC 5280 §4.2.1.3): OpenSSL's
+  `X509_CRL_sign()` does not check the issuer key's `keyUsage` extension. If a CA
+  certificate declared `keyUsage` without the `cRLSign` bit, the KMS would silently sign and
+  serve a CRL that RFC-conforming relying parties reject during path validation. Fix: added a
+  runtime check in `generate_crl()` using `x509_parser` that returns
+  `KmsError::InvalidRequest` with an RFC citation when `cRLSign` is absent.
+  Also regenerated `test_data/certificates/csr/intermediate.crt` (and `.p12`) to include
+  `cRLSign` in the `keyUsage` extension, as the previous fixture lacked it.
+  ([#987](https://github.com/Cosmian/kms/pull/987))
+
+- **MySQL: get_max_crl_number panics on empty crls table**: `SELECT MAX(crl_number) FROM crls`
+  returns a single row with a `NULL` value when the table is empty. The MySQL implementation
+  used `row.take::(0)` which panics in `mysql_common` on NULL conversion (line 123).
+  Fix: changed to `row.take::, _>(0).flatten()` — returns `None` for NULL,
+  `Some(v)` for an actual value. Caught by `tests::test_db_mysql` on CI
+  (mariadb non-fips, run `32632202380`). ([#987](https://github.com/Cosmian/kms/pull/987))
+
+## Testing (RFC compliance and role-based CRL)
+
+- **Comprehensive CRL test suite** (`crate/server/src/tests/crl_tests.rs`, 20 tests):
+  new dedicated test module covering all four mandatory layers:
+  - *Unit*: `test_build_empty_crl`, `test_build_crl_with_entries`,
+    `test_crl_reason_asn1_tag_is_enumerated` (asserts the `CRLReason` extension is encoded
+    as ASN.1 `ENUMERATED` tag `0x0A`, not `INTEGER` `0x02` — guards against future OpenSSL
+    ABI regression).
+  - *DB persistence* (`crl_persistence()` helper in `permissions_test.rs`, called from
+    every backend test): empty table → `None`, upsert round-trip, `MAX` across multiple
+    issuers, upsert-replace, `list_crl_issuers`, counter seed invariant
+    (`seed > db_max` always holds).
+  - *Functional*: empty CRL; CRL includes cert after revocation; CRL Number increases;
+    CRL persisted to DB; DER and PEM both valid; cache consistent with DB; public CDP
+    endpoint 404 before generation, valid DER after generation.
+  - *Security / non-regression*: `cRLSign` keyUsage enforcement (RFC 5280 §4.2.1.3);
+    non-certificate issuer rejected; `removeFromCRL` absent in complete CRL
+    (RFC 5280 §5.3.1); CRL Number monotonicity restart invariant; all 8 KMIP
+    `RevocationReasonCode` values produce the correct RFC 5280 reason codes with
+    ENUMERATED tag verification.
+
+- **CRL completeness with and without Crypto Officer role** (4 tests):
+  - *No-CO scenario* (`test_crl_no_co_all_revoked_certs_present`): alice owns the CA;
+    alice certifies `leaf_alice` (alice-owned); bob certifies `leaf_bob` via delegated
+    access (bob-owned). Alice and bob each self-revoke their own leaf. Alice generates
+    the CRL — both serials must be present, proving `find_all` crosses DB ownership
+    boundaries.
+  - *CO bypass scenario* (`test_crl_co_revokes_cert_owned_by_other_user`): CO=alice;
+    bob owns `leaf_bob`. Assert: bob is NOT CO; alice IS CO; bob cannot revoke alice's
+    cert (permission denied). Alice (as CO) revokes bob's cert via ownership bypass.
+    CRL must contain both (alice's leaf + bob's leaf).
+  - *Mixed scenario* (`test_crl_mixed_co_and_non_co_revocations_all_present`): CO=alice,
+    regular users bob and charlie. Alice (CO) revokes her own leaf and bob's leaf; charlie
+    self-revokes. Incremental CRL check after each event (1 → 2 → 3 entries). Final CRL
+    must contain all three serials.
+  - *Access control* (`test_crl_non_co_cannot_generate_crl_without_ca_access`): non-owner
+    non-CO user cannot generate the CRL for another user's CA.
+
+- **Counting-revoked-certificates tests** (2 tests, `COUNT_CERTS = 5`):
+  These are the definitive count-correctness gate. Each test revokes one cert at a time and
+  asserts the CRL entry count equals the number of revocations performed so far, with every
+  revoked serial present exactly once (no duplicates, no missing entries).
+  - `test_crl_counting_revoked_certs_no_co`: `ca_owner` owns the CA; 5 distinct non-CO users
+    each certify and self-revoke their own leaf. After every step k: count == k.
+  - `test_crl_counting_revoked_certs_with_co`: CO=alice owns CA; 5 distinct non-CO users
+    own one leaf each. Alice (CO) revokes each leaf via ownership bypass. Per-step assertion:
+    count == k; no duplicate serials. Proves CO bypass produces correct DB state that
+    `find_all` collects precisely.
+
+## Process
+
+- **Mandatory test coverage rule** (`.github/instructions/rust.instructions.md`): updated
+  the Testing section with a bold mandatory rule requiring four test layers for every new
+  Rust feature: (1) unit tests in `#[cfg(test)]` submodule, (2) DB persistence helper
+  called from all backend tests, (3) functional tests in a dedicated `_tests.rs`,
+  (4) security/non-regression tests. Includes per-layer content checklists, the CRL test
+  suite as the canonical reference implementation, and a template for new test files.

+
+**Summary:** Cosmian KMS fetched CRLs from URLs embedded in X.509 CRL Distribution Points (CDPs) during KMIP `Validate` and `Import` operations without applying any SSRF mitigations. The `get_crl_bytes()` function in `crate/server/src/core/operations/validate.rs` accepted arbitrary `http://` URLs (including loopback, private RFC-1918, and link-local addresses), followed HTTP redirects unconditionally, read the full response body without a size cap, and treated non-URL CDP values as local filesystem paths — allowing arbitrary file reads. A secondary vector existed via `file://` scheme URLs, which were explicitly converted to filesystem paths.
+
+This is a separate code path from COSMIAN-2026-009 (Google CSE `original_kacls_url` SSRF); the fix for that advisory did not cover CRL Distribution Point fetches.
+
+**Impact:** A post-authentication attacker with `Validate` or `Import` permission could:
+
+- Probe internal HTTP services reachable from the KMS host (confirmed blind SSRF via PoC on v5.26.0).
+- Access cloud metadata endpoints (e.g. `169.254.169.254`) from cloud-hosted deployments.
+- Read arbitrary local files readable by the KMS process via bare filesystem paths or `file://` URIs.
+- Cause denial of service via a slow or unbounded HTTP response body (no size cap, no timeout).
+
+**Mitigation:** Upgrade to 5.27.0. The fix adds `validate_crl_url()` in `crate/server/src/core/certificate/mod.rs` (HTTPS and HTTP allowed; private, loopback, link-local IPs and internal hostnames rejected), applies `reqwest::redirect::Policy::none()` and a 30-second timeout to the CRL-fetch client, caps responses at 10 MiB, and removes filesystem-path and `file://` CRL resolution in production builds (`file://` remains available in `#[cfg(test)]` only). Ten regression tests (SR-CRL-01 through SR-CRL-10) cover all mitigations.

+      description: |
+        Signs a fresh X.509 v2 Certificate Revocation List (CRL) for the CA identified
+        by `issuer_id` and returns it immediately.
+
+        **Why authentication is required**: generating a CRL uses the CA private key to
+        produce a cryptographic signature.  The caller must be authenticated so the server
+        can verify they have read access to the CA key via the normal object-level ACL.
+        No special role (Crypto Officer or otherwise) is required — any authenticated user
+        with access to the CA certificate may request its CRL.
+
+        The generated CRL is also persisted to the database and served by the public
+        distribution endpoint `GET /public/certificates/{issuer_id}/crl`.
+
+        **CRL content is public information** (RFC 5280 §3): it lists revoked certificate
+        serial numbers and contains no private key material.  Authentication here protects
+        the CA private key from being used as a signing oracle by unauthenticated callers.
+
+        Supported output formats:
+        - **DER** (default, `application/pkix-crl`, RFC 2585 §3)
+        - **PEM** (`application/x-pem-file`)

+      description: |
+        Returns the most recently generated CRL for the specified issuer.
+
+        This endpoint is intended for **CRL Distribution Point (CDP) URIs** embedded
+        in certificates. Standard PKI relying parties — browsers, TLS stacks, OCSP
+        clients — fetch CDP URIs without credentials, as required by RFC 5280 §3.
+
+        The CRL is served from the server's cache (no CA private key access at serve
+        time) and includes **all** revoked certificates issued by this CA regardless
+        of which user owns the corresponding DB record.
+
+        **Automatic refresh**: the CRL is regenerated automatically after every
+        certificate revocation and by a background scheduler before expiry.  The
+        server also loads the last signed CRL from the database on startup, so the
+        endpoint is immediately available without any manual call.
+
+        **Format**: always DER (`application/pkix-crl`).  Use the authenticated
+        `GET /certificates/{issuer_id}/crl?format=pem` endpoint for PEM output.
+
+        **HTTP caching**: responses include `Cache-Control: public, max-age=N` and
+        `Last-Modified` headers so that relying parties can cache the CRL and avoid
+        unnecessary round-trips.

+//! Comprehensive test suite for X.509 CRL generation and distribution.
+//!
+//! # Coverage matrix
+//!
+//! | Category | Tests |
+//! |----------|-------|
+//! | **Unit** | CRL builder: empty, with entries, reason ASN.1 tag (in `crypto::openssl::crl`) |
+//! | **Unit** | DB persistence: upsert, get, max, list, upsert-replace (in `database::permissions_test`) |
+//! | **Functional** | Empty CRL for CA with no revoked certs |
+//! | **Functional** | CRL includes cert after `Revoke` (all reason codes) |
+//! | **Functional** | CRL Number strictly increases across multiple generate calls |
+//! | **Functional** | Generated CRL is persisted to DB and survives in-process restart via cold-start warmup |
+//! | **Functional** | DER and PEM output both parse and verify |
+//! | **Functional** | Auto-CRL refresh triggered by `Revoke` when `kms_public_url` is set |
+//! | **Functional** | Public CDP endpoint returns cached CRL (DER, correct MIME type) |
+//! | **Security** | `cRLSign` keyUsage enforcement — CA without `cRLSign` is rejected |
+//! | **Security** | Non-CA object (symmetric key) used as issuer is rejected |
+//! | **Security** | All KMIP `RevocationReasonCode` values map to the correct RFC 5280 reason |
+//! | **Non-regression** | CRL Number monotonicity: simulated restart seed from DB max |
+//! | **Non-regression** | `removeFromCRL` reason code produces `Unspecified` (complete CRL only) |
+//! | **CO role** | No CO — each owner revokes their own cert; CRL contains all (`find_all` bypass) |
+//! | **CO role** | CO revokes cert owned by another user; appears in CRL |
+//! | **CO role** | Mixed: CO + non-CO revocations — all 3 entries in final CRL |
+//! | **CO role** | Non-CO without CA access cannot generate the CRL (permission denied) |
+//! | **Counting** | No-CO: N owners each self-revoke; CRL count == N after every step |
+//! | **Counting** | With CO: CO revokes K certs owned by others; CRL count == K after every step |

+# ADR-2026-08-20: PKI / X.509 CRL Generation, Distribution & Auto-Refresh Architecture
+
+## Status
+
+Proposed | **Accepted** | Rejected | Superseded | Deprecated
+
+> **Revised 2026-08-23** — updated to reflect implementation changes from PR #987:
+> CO-guard removal, DB-backed CRL Number monotonicity, auto-refresh on `Revoke`,
+> corrected scheduler defaults, RFC 5280 compliance fixes, `CrlConfig` grouping,
+> and comprehensive test suite.
+
+## Context
+
+The Eviden KMS already supported certificate issuance (KMIP `Certify` operation) and
+revocation (KMIP `Revoke`). However, the revocation data was entirely internal to the KMS
+database. Any PKI relying party (TLS stack, browser, OCSP client) needed a Certificate
+Revocation List (CRL) to enforce revocation, and no such CRL distribution mechanism existed.
+
+Several constraints drove the design:
+
+- **RFC 5280 §3 / §5**: CRL Distribution Point (CDP) URIs embedded in certificates must be
+  reachable by unauthenticated relying parties. The KMS cannot require OAuth2/JWT credentials
+  for a CDP endpoint.
+- **RFC 5280 §4.2.1.3**: The CA certificate used for CRL signing MUST have the `cRLSign` bit
+  set in its `keyUsage` extension. OpenSSL's `X509_CRL_sign()` does not enforce this; the
+  KMS must verify it before invoking the signing API.
+- **RFC 5280 §5.2.3**: CRL Number extensions must be monotonically increasing across CRL
+  generations, *including across server restarts*. A counter seeded only from the UTC
+  Unix timestamp could produce values lower than previously issued numbers after a restart
+  if many CRLs were generated before the restart. The counter must be seeded from
+  `max(unix_timestamp, db_max_crl_number + 1)`.
+- **RFC 5280 §5.3.2**: The `invalidityDate` CRL entry extension MUST always be encoded as
+  `GeneralizedTime`, not `UTCTime`. OpenSSL's `ASN1_TIME_set()` selects `UTCTime` for dates
+  before 2050; `ASN1_TIME_set_string()` with an explicit `YYYYMMDDHHmmssZ` string must be
+  used instead.
+- **FIPS 140-3**: CRL signing must use only FIPS-approved algorithms. Authority Key
+  Identifier construction was previously relying on `EVP_sha1()` (not FIPS-approved for new
+  use) and had to be replaced.
+- **Multi-CA**: the KMS can host multiple independent CAs. The solution must be per-issuer,
+  not global.
+- **Operator UX**: operators must be able to configure a public-facing `kms_public_url` and
+  have CDP URIs auto-inserted into newly issued certificates without manual configuration.
+- **Cold-start availability**: the public CDP endpoint must be immediately available after a
+  server restart without requiring a manual `generate-crl` call.
+- **Access control**: CRL *content* is public information (RFC 5280 §3). The authenticated
+  `generate-crl` endpoint protects the CA *private key* from being used as a signing oracle
+  by unauthenticated callers. No special role (Crypto Officer or otherwise) is required
+  beyond the standard read-access check on the CA certificate.
+
+## Decision
+
+Implement a four-tier CRL architecture:
+
+### Tier 1 — Authenticated CRL generation endpoint
+
+`GET /certificates/{issuer_id}/crl` (requires authentication)
+
+- Signs a fresh X.509 v2 CRL using the CA's private key from the KMS key store.
+- Before signing, enforces RFC 5280 §4.2.1.3: the CA certificate MUST have `cRLSign` in
+  its `keyUsage` extension. Returns `InvalidRequest` if the bit is absent.
+- Lists all certificates with `CertificateLink → issuer_id` and KMIP state `Deactivated` or
+  `Compromised`, via `find_all` (bypasses user ownership filters so the CRL is complete
+  regardless of who owns each cert record in the DB).
+- Any authenticated user with `Get` access to the CA certificate may call this endpoint.
+  No Crypto Officer role is required — CRL content contains no private key material.
+- Supports `format=der` (default, `application/pkix-crl`) and `format=pem`
+  (`application/x-pem-file`) query parameters.
+- Supports `validity_days` override (server default: 7 days, range: 1–365, configured via
+  `crl_default_validity_days` in `CrlConfig`).
+- CRL Number is assigned from a per-`KMS`-instance `Arc` seeded at startup from
+  `max(unix_timestamp, db_max_crl_number + 1)`, guaranteeing strict monotonicity across both
+  concurrent calls and server restarts (RFC 5280 §5.2.3).
+- Writes the signed CRL DER and `next_update` timestamp to the `crls` database table
+  (non-fatal on DB error — in-memory cache still works).
+- Populates a process-local `GENERATED_CRL_CACHE` (`LazyLock>>`) for fast re-serving.
+- Also exposed as a new CLI command `ckms certificates generate-crl` and Web UI action
+  (Certificates → Certs → Generate CRL).
+
+### Tier 2 — Unauthenticated public CDP endpoint
+
+`GET /public/certificates/{issuer_id}/crl` (no authentication)
+
+- Serves pre-signed CRL DER bytes from the two-level cache (in-memory → DB fallback on
+  cold start).
+- Returns HTTP 404 with a diagnostic message until the cache is primed.
+- Sets `Last-Modified` (RFC 7231 IMF-fixdate), `Cache-Control: public, max-age=N` (derived
+  from `nextUpdate − 60 s`), and `Content-Disposition` headers.
+- Intended as the CDP URI in `crlDistributionPoints` extensions:
+  `{kms_public_url}/public/certificates/{issuer_id}/crl`.
+- Does **not** sign fresh CRLs — it only serves the last signed bytes; no key material is
+  accessed on this path.
+
+### Tier 3 — Scheduled CRL auto-refresh
+
+A background cron task (`spawn_crl_refresh_cron`) wakes every `crl_refresh_check_hours`
+(default: **1 h**, 0 = disabled) and regenerates any stored CRL whose `next_update` timestamp
+falls within `crl_refresh_overlap_hours` (default: **24 h**) of the current time.
+
+This models the *CRL overlap window* pattern (EJBCA "CRL Overlap Time", AWS PCA 1-day overlap):
+the new CRL is signed before the old one expires, so relying parties always have a valid CRL
+even if no revocation event triggered a manual regeneration.
+
+The cron runs in its own OS thread with a single-threaded Tokio runtime to avoid contention
+with the main Actix-web executor. It is shut down cleanly via a `oneshot::Sender<()>` held by
+the server startup routine.
+
+### Tier 4 — Auto-injection of CDP extension into issued certificates
+
+When `kms_public_url` is configured, the `Certify` operation automatically inserts a
+`crlDistributionPoints` extension (RFC 5280 §4.2.1.13) pointing to the public CDP endpoint
+into newly issued non-self-signed certificates, unless the subject or the caller already
+provides a CDP.
+
+Self-signed certificates receive `id-ce-noRevAvail` (RFC 9608) instead, since self-signed
+certs cannot appear in a CRL they also sign.
+
+Re-certifications that already carry a CDP are not modified.
+
+### Tier 5 — Automatic CRL refresh on `Revoke`
+
+When `kms_public_url` is configured (i.e., the server knows its own public URL), every
+successful `Revoke` operation on a certificate triggers a background `generate_crl` call for
+the issuing CA. This is a *fire-and-forget* task: errors are logged at `WARN` and do not
+affect the revocation response. The intent is to keep the public CDP as fresh as possible
+without operator intervention, while not adding synchronous signing latency to the hot
+`Revoke` path.
+
+### FIPS-safe AKI construction
+
+The `AuthorityKeyIdentifier` CRL extension (RFC 5280 §5.2.1) is constructed manually
+using a low-level SHA-1 hash of the issuer's SPKI DER via `openssl::sha::Sha1`
+(C interface, bypasses the FIPS provider check). This approach is intentional:
+the AKI is a key identifier, not a cryptographic commitment; RFC 5280 §4.2.1.1 explicitly
+permits SHA-1 for this use; and the FIPS provider's prohibition covers digest *algorithms
+in security services* (e.g. signatures), not identifier derivation. The CRL signature itself
+uses only FIPS-approved algorithms.
+
+### Database persistence (`crls` table)
+
+A new `crls` table stores `(issuer_id, crl_der, crl_number, generated_at, next_update)`.
+This enables cold-start recovery: on the first request to the public CDP after a restart,
+the server loads the last persisted CRL from DB into the in-memory cache. The DB write in
+`generate_crl` is best-effort — a DB failure is logged as `WARN` and does not fail the
+authenticated CRL generation request.
+
+A new `get_max_crl_number()` method on the `PermissionsStore` trait (implemented for
+SQLite, PostgreSQL, MySQL, and Redis) returns the highest stored `crl_number`. This is
+called once during `KMS::instantiate()` to seed the CRL counter correctly.
+
+### Configuration — `CrlConfig` struct
+
+The three CRL lifecycle parameters are grouped in a dedicated `CrlConfig` struct using
+`#[command(flatten)]` in `ClapConfig`. This is consistent with the existing `VaultConfig`,
+`JwksEndpointConfig`, and `RolesConfig` patterns. The TOML keys and CLI flags are unchanged
+(flat naming with `crl_` prefix), so existing operator configurations are not affected.
+
+## Consequences
+
+### Positive
+
+- **POS-001**: Full RFC 5280 §5 CRL distribution chain from issuance to revocation to
+  relying-party validation, without requiring any external OCSP infrastructure.
+- **POS-002**: Unauthenticated CDP endpoint aligns with RFC 5280 §3 requirements; no
+  credential leakage risk since it serves pre-signed, immutable DER bytes.
+- **POS-003**: CRL Number monotonicity guaranteed across restarts via DB-seeded counter
+  (`max(unix_timestamp, db_max + 1)`). One `SELECT MAX(crl_number)` query is executed at
+  server startup; no per-generation DB round-trip is required.
+- **POS-004**: Operator configuration is minimal — setting `kms_public_url` is sufficient
+  to activate end-to-end CDP injection and auto-refresh on revocation; no per-CA
+  configuration needed.
+- **POS-005**: FIPS compliance maintained for AKI construction (SHA-1 via C bypass) and
+  `invalidityDate` encoding (always `GeneralizedTime` via `ASN1_TIME_set_string`), without
+  compromising the overall FIPS posture.
+- **POS-006**: DB persistence ensures the public CDP endpoint survives server restarts
+  without requiring a warm-up call.
+- **POS-007**: Auto-refresh on `Revoke` (Tier 5) keeps the public CDP current with no
+  operator intervention, while the fire-and-forget design avoids adding HSM signing latency
+  to the hot revocation path.
+- **POS-008**: `cRLSign` keyUsage enforcement (RFC 5280 §4.2.1.3) prevents generating CRLs
+  that RFC-conforming relying parties would reject during path validation.
+
+### Negative
+
+- **NEG-001**: The public CDP endpoint serves *stale* CRLs between `generate-crl` calls.
+  Relying parties may not see a revocation until the CA owner regenerates the CRL (or the
+  Tier 5 auto-refresh fires). This is the standard CRL trade-off (vs. OCSP stapling);
+  operators must configure appropriate `validity_days` and/or automate CRL regeneration
+  on revocation events.
+- **NEG-002**: The in-memory cache is per-process. Multi-instance deployments behind a
+  load balancer will have independent caches; only the instance that handled the last
+  `generate-crl` request has the fresh CRL in RAM (all instances share the DB-persisted
+  copy after a DB write succeeds).
+- **NEG-003**: The `crls` table introduces a new DB schema dependency. Existing deployments
+  require a schema migration before upgrading.
+- **NEG-004**: CRL generation requires the issuer's private key to be accessible in the KMS
+  key store at request time. HSM-backed keys add latency on each `generate-crl` call.
+
+## Alternatives Considered
+
+### OCSP (Online Certificate Status Protocol, RFC 6960)
+
+- **ALT-001 Description**: Deploy an embedded OCSP responder alongside the KMS. Relying
+  parties query per-certificate status in real time.
+- **ALT-002 Rejection Reason**: OCSP requires per-request signing with a short-lived OCSP
+  signing certificate, nonce handling, and significant additional protocol surface area.
+  CRL is the simpler baseline required by most enterprise PKI stacks and is a prerequisite
+  before OCSP can be considered. OCSP stapling can be added as a future enhancement.
+
+### Auto-regenerate CRL on every `Revoke` call — synchronously
+
+- **ALT-003 Description**: Trigger `generate_crl` synchronously (in the same request
+  transaction) every time a `Revoke` operation completes, keeping the public CDP always
+  current.
+- **ALT-004 Rejection Reason**: Revoke is a hot path; synchronous signing requires private
+  key access (potentially HSM) and a DB round-trip, adding measurable latency. The
+  implemented solution (Tier 5) achieves the same freshness goal via an asynchronous
+  fire-and-forget task that does not block the `Revoke` response.
+
+### Store CRL in object store / S3
+
+- **ALT-005 Description**: Push signed CRL bytes to an object store (S3, GCS) and serve
+  from there, decoupling CRL distribution from the KMS process.
+- **ALT-006 Rejection Reason**: Introduces an external dependency and complicates
+  deployment. The KMS already owns a database with reliable persistence; the `crls` table
+  is the simplest consistent extension of existing infrastructure.
+
+### External CRL signer (offline CA)
+
+- **ALT-007 Description**: Keep the signing CA key offline; export a signing request to an
+  offline process.
+- **ALT-008 Rejection Reason**: Out of scope for the KMS, which is designed to be the
+  online CA. Offline CA workflows require a separate product and are not addressed by this
+  ADR.
+
+## Implementation Notes
+
+- **IMP-001**: `GENERATED_CRL_CACHE` is a `LazyLock>>`.
+  The `RwLock` is async-aware to avoid blocking the Actix-web thread pool on cache reads
+  (which are the hot path for the public endpoint).
+- **IMP-002**: The CRL sequence counter is a `crl_counter: Arc` field on the
+  `KMS` struct. During `KMS::instantiate()`, the highest `crl_number` is read from the
+  `crls` table via `get_max_crl_number()`. The counter is then seeded as
+  `max(unix_timestamp, db_max + 1)`, guaranteeing strict monotonicity across restarts even
+  when many CRLs have been generated (RFC 5280 §5.2.3). `fetch_add` with `Ordering::Relaxed`
+  ensures uniqueness within a single process.
+- **IMP-003**: The `build_crl` function in `crate/crypto/src/openssl/crl.rs` encapsulates
+  all OpenSSL CRL construction. The `invalidityDate` entry extension uses
+  `ASN1_TIME_set_string` with an explicit `"YYYYMMDDHHmmssZ"` string to always produce
+  `GeneralizedTime` encoding (RFC 5280 §5.3.2 MUST). A regression test
+  (`test_invalidity_date_encoded_as_generalized_time`) asserts the DER tag byte is `0x18`
+  for a pre-2050 date. The file is covered by FIPS-mode integration tests.
+- **IMP-004**: All new DB operations (`get_crl`, `upsert_crl`, `list_crl_issuers`,
+  `get_max_crl_number`) implement SQLite, PostgreSQL, MySQL, and Redis backends. The MySQL
+  implementation uses `row.take::, _>(0).flatten()` for `get_max_crl_number` to
+  handle the `NULL` returned by `MAX()` on an empty table without panicking.
+- **IMP-005**: The `encode_der_length` helper in `build_certificate.rs` returns `KResult<()>`
+  to prevent silent truncation of CDP URIs longer than 65 535 bytes.
+- **IMP-006**: The `cRLSign` keyUsage enforcement check in `generate_crl()` uses
+  `x509_parser` to parse the issuer certificate's extensions and return
+  `KmsError::InvalidRequest` if `cRLSign` is absent (RFC 5280 §4.2.1.3). OpenSSL's
+  `X509_CRL_sign()` does not perform this check itself.
+- **IMP-007**: The KMIP 1.4 TTLV normalizer (`ttlv/normalize.rs`) was fixed to preserve
+  structured `AttributeValue` children (e.g. `RevocationReason`) instead of unconditionally
+  collapsing single-child nodes. The old behaviour caused `RevocationReason` deserialization
+  failures during `Revoke` processing when attributes arrived as KMIP 1.4 `Attribute`
+  structures. The fix ensures only primitive-typed children (TextString, Integer, etc.) are
+  collapsed; structured children retain their wrapper.
+- **IMP-008**: CRL lifecycle configuration (`crl_default_validity_days`,
+  `crl_refresh_check_hours`, `crl_refresh_overlap_hours`) is grouped in a dedicated
+  `CrlConfig` struct using `#[command(flatten)]` in `ClapConfig`. TOML keys and CLI flags
+  are unchanged (flat naming with `crl_` prefix), so existing configurations are not
+  affected.
+- **IMP-009**: Success criteria — the following test suites pass on all DB backends in both
+  FIPS and non-FIPS modes:
+    - `crate/server/src/tests/crl_tests.rs` — 20 server-level tests covering unit, functional,
+    security (cRLSign enforcement, reason code mapping), non-regression (CRL Number
+    monotonicity restart simulation), and REST endpoint checks.
+    - `crate/server/src/tests/crl_tests.rs` — 4 CO role scenario tests (no-CO, CO bypass,
+    mixed, access control) and 2 counting tests verifying exact CRL entry count invariant.
+    - `crate/server_database/src/tests/permissions_test.rs` — `crl_persistence()` helper
+    testing `upsert_crl`, `get_crl`, `get_max_crl_number`, and `list_crl_issuers` across
+    all DB backends.

 ## Links between tables
 
 - `objects.id` is referenced by `read_access.id` and `tags.id`: one object can have many access rows and many tags.
 - `objects.wrapping_key_id` points to `objects.id`: a wrapping key is itself an object, and many objects can be wrapped by the same key.
+- `crls.issuer_id` logically references `objects.id` (the CA certificate): one CA has at most one current CRL row.
 - `objects.owner` and `read_access.userid` hold user identifiers.
   Users are authenticated identities and are **not** stored in a dedicated table.
 - `parameters` and `crypto_officer_activations` are standalone and do not reference `objects`.

+# Revocation & CRL Distribution
+
+Certificate revocation in the Eviden KMS follows the two-phase model defined by
+[RFC 5280](https://www.rfc-editor.org/rfc/rfc5280):
+
+1. **Revoke** a certificate — the KMIP `Revoke` operation marks the certificate
+   `Deactivated` or `Compromised` in the KMS database.
+2. **Publish** the revocation — the `Generate-CRL` operation (or automatic
+   post-revocation refresh) signs a fresh CRL that relying parties can fetch.
+
+## CRL generation
+
+The KMS generates X.509 v2 Certificate Revocation Lists (CRLs) per
+[RFC 5280 §5](https://www.rfc-editor.org/rfc/rfc5280#section-5).
+
+A CRL lists all certificates issued by a CA that have been revoked. The KMS
+automatically collects **all** revoked certificates — those in `Deactivated` or
+`Compromised` state with a `CertificateLink` pointing to the issuer — regardless
+of which user owns each certificate record in the KMS database, then signs the
+CRL with the CA private key.
+
+**CLI usage:**
+
+```bash
+ckms certificates generate-crl \
+  --certificate-id  \
+  --validity-days 7 \
+  --output-format pem \
+  --output-file /tmp/crl.pem
+```
+
+**REST endpoint (authenticated):**
+
+```http
+GET /certificates/{issuer_id}/crl?format=pem&validity_days=7
+```
+
+Returns `application/pkix-crl` (DER, default) or `application/x-pem-file` (PEM).
+
+!!! note "Access control"
+    Any **authenticated** user with `Get` access to the CA certificate may call
+    this endpoint — no Crypto Officer role is required. CRL content is public
+    information (RFC 5280 §3); the authentication check exists to prevent the CA
+    private key from being used as an unauthenticated signing oracle, not to
+    restrict access to the revocation list itself.
+
+The generated CRL includes:
+
+- **Authority Key Identifier** (AKI) — derived from the CA's `subjectKeyIdentifier`
+  extension if present, or from a SHA-1 hash of the CA's `SubjectPublicKeyInfo` DER.
+- **CRL Number** — monotonically increasing integer, seeded at startup from
+  `max(unix_timestamp, db_max_crl_number + 1)` to guarantee strict monotonicity
+  across server restarts (RFC 5280 §5.2.3).
+- Per-entry **CRL Reason Code** — mapped from the KMIP revocation reason stored at
+  revocation time (RFC 5280 §5.3.1).
+- Per-entry **Invalidity Date** — `GeneralizedTime`-encoded date of compromise when
+  available in object attributes (RFC 5280 §5.3.2).
+
+### Configuration
+
+```toml
+# kms.toml
+[crl]
+crl_default_validity_days = 7   # default CRL validity in days (1–365)
+crl_refresh_check_hours   = 1   # background refresh check interval; 0 = disabled
+crl_refresh_overlap_hours = 24  # pre-regenerate this many hours before expiry
+```
+
+All three keys may also be set as CLI flags or environment variables:
+
+```bash
+--crl-default-validity-days 7
+--crl-refresh-check-hours   1
+--crl-refresh-overlap-hours 24
+```
+
+## Automatic CRL regeneration on revocation
+
+When `kms_public_url` is set in `kms.toml`, the server **automatically regenerates**
+the issuer's CRL in the background whenever a certificate is revoked via the
+`Revoke` operation. The regeneration is fire-and-forget: it does not block the
+`Revoke` response, and any signing failure is logged at `WARN` level without
+affecting the revocation outcome.
+
+```toml
+# kms.toml — enables CDP auto-injection and auto-CRL regeneration
+kms_public_url = "https://kms.example.com"
+```
+
+The updated CRL is immediately available at the public CDP endpoint:
+
+```http
+GET /public/certificates/{issuer_id}/crl    # no authentication required
+```
+
+## Scheduled CRL refresh
+
+A background scheduler wakes every `crl_refresh_check_hours` (default: 1 h) and
+regenerates any stored CRL whose `nextUpdate` timestamp falls within
+`crl_refresh_overlap_hours` (default: 24 h) of the current time. This prevents
+relying parties from seeing an expired CRL during the window between the scheduled
+expiry and the next revocation-triggered regeneration.
+
+Set `crl_refresh_check_hours = 0` to disable the background scheduler entirely
+(CRLs will only be refreshed on explicit `generate-crl` calls or `Revoke` events).
+
+## CRL distribution points
+
+When `kms_public_url` is configured, the KMS **automatically injects** a
+`crlDistributionPoints` (CDP) extension into every CA-issued certificate, pointing
+to the server's own public CRL endpoint:
+
+```text
+https:///public/certificates//crl
+```
+
+You do **not** need to supply a CDP extension manually for KMS-issued certificates
+when `kms_public_url` is set.
+
+To override or set a custom CDP manually (e.g. for an external CA), add a
+`crlDistributionPoints` entry in the extension config file passed via
+`--certificate-extensions`:
+
+```ini
+[ v3_ext ]
+crlDistributionPoints=URI:http://ca.example.com/crl.pem
+```
+
+## Public (unauthenticated) CRL endpoint
+
+`GET /public/certificates/{issuer_id}/crl` is intended for CRL Distribution Point
+(CDP) URIs embedded in certificates. Any relying party — browser, TLS stack, OCSP
+client — can fetch the current CRL without credentials, as required by
+[RFC 5280 §3](https://www.rfc-editor.org/rfc/rfc5280#section-3).
+
+The response includes:
+
+- `Content-Type: application/pkix-crl`
+- `Last-Modified` (RFC 7231 IMF-fixdate)
+- `Cache-Control: public, max-age=N` where N is derived from `nextUpdate − 60 s`
+
+The endpoint returns **404** only if the CRL has never been generated and no CRL
+is stored in the database.
+
+!!! note "Cold-start behaviour"
+    Generated CRLs are persisted in the KMS database (`crls` table) and reloaded
+    on server restart, so the public endpoint continues to serve the last signed CRL
+    without requiring a manual `generate-crl` call after each restart.
+
+## Authority Information Access (AIA)
+
+The AIA extension (`authorityInfoAccess`, OID `1.3.6.1.5.5.7.1.1`) can be added
+via the extension config file to point relying parties to an OCSP responder or to
+the CA issuer certificate:
+
+```ini
+[ v3_ext ]
+authorityInfoAccess=OCSP;URI:http://ocsp.example.com/,caIssuers;URI:http://ca.example.com/ca.crt
+```
+
+!!! note "OCSP responder not built in"
+    The KMS does not embed an OCSP responder. The AIA extension can reference an
+    external OCSP service. CRL-based revocation is fully supported; OCSP is a
+    future enhancement.
+
+## No Revocation Available (`id-ce-noRevAvail`, RFC 9608)
+
+For **self-signed certificates** (no issuer key provided) that do not carry a CRL
+distribution point, the KMS automatically adds the `id-ce-noRevAvail` extension
+(OID `2.5.29.56`, RFC 9608 §2). This signals to relying parties that no
+revocation information is available for this certificate, and that they MUST NOT
+reject it for lack of a CRL or OCSP response.
+
+This behaviour applies to **all algorithms** (RSA, EC, ML-DSA, SLH-DSA, …).
+
+When validating a chain, the KMS skips CRL fetching for any certificate that
+carries this extension.

-## Revocation handling
-
-### CRL distribution points
-
-To include a CRL distribution point in a certificate, add a
-`crlDistributionPoints` entry in the extension config file passed via
-`--certificate-extensions`:
-
-```ini
-[ v3_ext ]
-crlDistributionPoints=URI:http://ca.example.com/crl.pem
-```
-
-### Authority Information Access (AIA)
-
-The AIA extension (`authorityInfoAccess`, OID 1.3.6.1.5.5.7.1.1) can be added
-via the extension config file to point to an OCSP responder or CA issuer:
-
-```ini
-[ v3_ext ]
-authorityInfoAccess=OCSP;URI:http://ocsp.example.com/,caIssuers;URI:http://ca.example.com/ca.crt
-```
-
-### No Revocation Available (`id-ce-noRevAvail`, RFC 9608)
-
-For **self-signed certificates** (no issuer key provided) that do not carry a
-CRL distribution point, the KMS automatically adds the
-`id-ce-noRevAvail` extension (OID 2.5.29.56, RFC 9608 §2). This signals
-to relying parties that no revocation information is available for this
-certificate, and that they should not reject it for lack of a CRL or OCSP
-response.
-
-This behavior applies to **all algorithms** (RSA, EC, ML-DSA, SLH-DSA, …),
-not only PQC.
-
-When validating a chain, the KMS skips CRL fetching for any certificate that
-carries this extension.
