RustCrypto: SSH Symmetric Ciphers

Documentation

About

Pure Rust implementation of SSH symmetric encryption including support for the modern aes128-gcm@openssh.com/aes256-gcm@openssh.com and chacha20-poly1305@openssh.com algorithms as well as legacy support for older ciphers.

Built on the pure Rust cryptography implementations maintained by the RustCrypto organization.
