ChaCha20
ChaCha20 is a stream cipher which is designed to support high-performance software implementations.
It improves upon the previous Salsa20 stream cipher with increased per-round diffusion at no cost to performance.
Security Warning
This crate does not ensure ciphertexts are authentic! Thus ciphertext integrity is not verified, which can lead to serious vulnerabilities!
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.
