Godoc Reference

The poly1305 message authentication code

Poly1305 is a fast, one-time authentication function created by Daniel J. Bernstein.
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.
