Detailed Description

POLY1305 Message Authentication Code.

Description

POLY1305 generates a 16-byte tag which authenticates a message given a 32-byte key. The 32-byte key can be made of two 16-byte keys, e.g. the first 16-byte key is an AES key and the remaining 16-byte come from a random string. POLY1305 has been designed with the AES but it can be used with any other secure cipher, e.g. Chacha20.
