Pull request overview
This pull request implements a server-side SSH key generation feature for Semaphore UI. Users can now optionally generate SSH key pairs on the server instead of providing their own private keys. The generated public key is displayed to users for copying to authorized_keys files on target systems.
Changes:
- Added server-side SSH key generation using RSA 2048-bit keys with public/private key pair creation
- Implemented UI components to display generated public keys in a dialog with copy-to-clipboard functionality
- Extended database schema to store public key metadata in the Plain field for SSH keys
- Added generate_ssh_key flag to control key generation behavior in the frontend and backend

The checkbox label "Generate SSH Key" is hardcoded and not internationalized, while other labels in the form use the i18n translation function. This creates inconsistency with the rest of the codebase where all user-facing strings are translated.
Consider changing label="Generate SSH Key" to :label="$t('generateSshKey')" and adding the corresponding translation keys.

Inline styles are used extensively for the public key display section. Consider extracting these styles to a scoped <style> section or using CSS classes for better maintainability and consistency. This makes it easier to maintain and update styling across the application.

Inline styles are duplicated between KeyForm.vue and Keys.vue for displaying the public key. The same styling is applied to the <pre> element in both files (gray background, white color, border-radius, etc.). Consider creating a reusable component or shared styles to avoid this duplication and ensure consistency.

The logic for determining if a public key should be shown on update (line 156) assumes that if generate_ssh_key is true, a key was generated. However, this flag comes from the request body, not the response. If the backend fails to generate the key (but doesn't return an error), or if the key generation is skipped for some reason, the dialog may still appear with an empty public key. Consider adding an additional check to ensure the public key was actually generated before showing the dialog.

The SSH key generation functionality introduced by this PR lacks automated test coverage. Consider adding tests to verify that maybeGenerateSSHPrivateKey correctly generates keys when GenerateSSHKey is true, sets the Plain field with the public key, and properly handles the case when GenerateSSHKey is false. Tests should also verify that the generated private key is valid and properly encrypted.
Example test cases to add:
- Test that GenerateSSHKey=true generates both private and public keys
- Test that GenerateSSHKey=false preserves existing private key
- Test that Plain field is set correctly with public key JSON
- Test that generated keys are valid RSA keys

The checkbox for generating SSH keys is only disabled when canEditSecrets is false, but it should also be disabled for existing keys where override_secret is required. When editing an existing key without override_secret checked, users can toggle generate_ssh_key, but this won't have any effect because the secret won't be updated. This creates a confusing user experience.
Consider adding || (!isNew && !item.override_secret) to the disabled condition to make it clear that SSH key generation only works when secrets can be edited.

The dialog title "Generated SSH Public Key" is hardcoded and not internationalized. All other strings in the file use the i18n translation function (e.g., $t('create'), $t('save')). This string should be extracted to the translation files for consistency and to support multiple languages.
Consider changing title="Generated SSH Public Key" to title="$t('generatedSshPublicKey')" and adding the corresponding translation keys.

Security review outcome (PR #3656)
Verdict: No medium, high, or critical vulnerabilities validated in the added/modified code.
Prior findings re-checked: The
UpdateAccessKeyOverrideSecretargument mismatch (db/sql/access_key.go) is a functional regression (SQLite/Go drivers reject the extra binding — updates fail with an argument-count error rather than silently corruptingsource_storage_*columns). That does not provide a plausible attacker-controlled exploit path under existingCanManageProjectResourcesauth, so it is not reported as a security finding here.Other paths reviewed: SSH key generation uses
crypto/rand+ RSA-2048; API controllers strip client-suppliedplain; private keys stay out of JSON (secrethasjson:"-"); Vue public-key display uses text interpolation (low XSS risk for server-generated keys).Slack summary: PR
feat/gen_ssh_key— no medium+ security issues found. SQLOverrideSecretarg mismatch is a functional bug (failed updates), not an exploitable integrity/confidentiality issue. Prior automation threads cleared.No Slack integration configured; summary included above.

Security review — PR #3656
Outcome: No medium, high, or critical vulnerabilities found.
Prior findings validated
Earlier automation runs flagged a High SQL placeholder mismatch in db/sql/access_key.go (key.Plain appended without a matching plain=? in the OverrideSecret UPDATE clause). Commit f12be5c0 fixes this by adding plain=? to the clause so placeholders and args align. Resolved.
Areas reviewed
- Authn/authz: Key create/update/list routes remain behind
CanManageProjectResources;generate_ssh_keyis server-side only and cannot bypass permission checks. - Secret handling: Request bodies still zero
key.Plainbefore processing; private keys are stored viaSerializeSecretand are not returned in API responses (json:"-"onSecret). - Injection / XSS: Key generation uses Go
crypto/rsa; UI renders the public key with Vue text interpolation (auto-escaped). - Information disclosure:
plainnow carries generated public-key JSON; exposure is limited to authorized project resource managers and is intentional for copy-to-clipboard UX.
Notes (non-security)
CreateAccessKeyusesIgnorePlain=true, so generated public keys are returned once on create but not persisted until a later override update.maybeGenerateSSHPrivateKeyclearsplainwhengenerate_ssh_keyis false on override updates; this is a data-integrity/UI concern, not a privilege-boundary issue (no server-side security decisions depend onplain).

🌐 Web query:
PostgreSQL UPDATE SET same column more than once duplicate target column specified behavior
💡 Result:
In PostgreSQL, specifying the same target column more than once in the SET clause of an UPDATE statement is not allowed and will result in an error [1]. Specifically, executing such a command will raise an error stating: ERROR: multiple assignments to same column "column_name" [1]. This behavior occurs because the order of assignments in an UPDATE statement is not significant, and all expressions in the SET clause are evaluated using the "old" (pre-update) values of the row [1]. Since PostgreSQL cannot determine a meaningful order of precedence for conflicting assignments to the same column, it prohibits the duplicate specification entirely [1]. To perform multiple updates on the same column, you must use separate UPDATE statements [2]. Additionally, when referencing columns within an UPDATE, keep in mind that all column references in your expressions refer to the original values of the row at the start of the update operation, not any new values being assigned in the same statement [1].

Assign plain only once.
When OverrideSecret is true and IgnorePlain is false, UpdateAccessKey emits two plain=? assignments. PostgreSQL rejects this statement, while SQLite applies the later assignment. Use else if !key.IgnorePlain for the ordinary update path. Add tests for all four flag combinations.
