binkey

binkey is a rust-based encryption tool that transforms any file into a self-extracting, passphrase-protected executable. designed for secure distribution and storage of sensitive data, each encrypted file is a standalone entity, containing a copy of binkey itself, eliminating the need for a separate decryption tool.

features

• self-contained executables: each encrypted file is a complete executable, containing a copy of binkey for self-extraction.
• passphrase protection: secures files with aes-256 encryption, unlocked only with a user-defined passphrase.
• delimiter-driven encryption: utilizes unique delimiters to identify encrypted data segments within the binary.

how it works

binkey employs base64 encoding and aes-256 encryption for securing files. each encrypted file is encapsulated between unique header and footer delimiters, marking the encrypted data segment within the binary.

encryption

to encrypt a file:

binkey file [outfile] -p <passphrase>

decryption

running the encrypted file prompts for the passphrase, allowing for decryption and extraction of the original content without needing an external binkey installation.

build it

cargo build --release

maybe upx or use some other packer to reduce the footprint even smaller. currently sitting around 1mb.
