Pure Rust implementation of **AES256-CTR/Poly1305-AES**: an
[Authenticated Encryption with Associated Data (AEAD)][2] cipher amenable to
fast, constant-time implementations in software, based on the [AES256-CTR][3]
stream cipher and the Poly1305-AES MAC which uses the [Poly1305][4] universal
hash function in combination with the [AES-128][5] block cipher.
A lot code is copied from the [chacha20poly1305 crate][6]
[Documentation][docs-link]
## About
AES256-CTR is widely known as stream cipher using the AES256 block cipher.
Poly1305-AES as MAC has been proposed by Daniel J. Bernstein in his famous paper
[The Poly1305-AES message-authentication code][7].
While both the stream cipher and the MAC are not commonly used, there exists
software which uses the combination to encrypt and authenticate the data, e.g.
the backup software [restic][8].
