## 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.
