Poly1305 is a universal hash family designed by Daniel J. Bernstein in 2002 for use in cryptography. As with any universal hash family, Poly1305 can be used as a one-time message authentication code to authenticate a single message using a secret key shared between sender and recipient, similar to the way that a one-time pad can be used to conceal the content of a single message using a secret key shared between sender and recipient.
