RustCrypto: Kuznyechik Cipher

crate Docs Apache2/MIT licensed Rust Version Project Chat Build Status HAZMAT

Pure Rust implementation of the Kuznyechik (GOST R 34.12-2015) block cipher

⚠️ Security Warning: Hazmat!

This crate does not ensure ciphertexts are authentic (i.e. by using a MAC to verify ciphertext integrity), which can lead to serious vulnerabilities if used incorrectly!

No security audits of this crate have ever been performed, and it has not been thoroughly assessed to ensure its operation is constant-time on common CPU architectures.
