-Package poly1305 implements Poly1305 one-time message authentication code as

-
-Poly1305 is a fast, one-time authentication function. It is infeasible for an
-attacker to generate an authenticator for a message without the key. However, a
-key must only be used for a single message. Authenticating two different
-messages with the same key allows an attacker to forge authenticators for other
-messages with the same key.
-
-Poly1305 was originally coupled with AES in order to make Poly1305-AES. AES was
-used with a fixed key in order to generate one-time keys from an nonce.
-However, in this package AES isn't used and the one-time key is specified
