Poly1305 is a purpose-built MAC, as opposed to something like an HMAC using SHA256 which leverages an existing hash scheme to build a message authentication code. Purpose-built introduces new complexity, but also allows for increased performance.

ChaCha20 and Poly1305 are both implemented in this crate to keep dependencies to a minimum.

## Development

The implementation is tested against vectors from the BIP324 reference and a number of additional library tests.
