Poly1305 message authentication reference implementation using AES

Poly1305-AES is a state-of-the-art secret-key message-authentication code suitable for a wide variety of applications.

Poly1305-AES computes a 16-byte authenticator of a message of any length, using a 16-byte nonce unique message number and a 32-byte secret key. Attackers can’t modify or forge messages if the message sender transmits an authenticator along with each message and the message receiver checks each authenticator.
