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.

Minimum Supported Rust Version

This crate requires Rust 1.60 at a minimum.

We may change the MSRV in the future, but it will be accompanied by a minor version bump.
