Detailed Description

This file contains Poly1305 definitions and functions.

     Poly1305 is a one-time message authenticator that can be used to
     authenticate messages. Poly1305-AES was created by Daniel
     Bernstein https://cr.yp.to/mac/poly1305-20050329.pdf The generic
     Poly1305 algorithm (not tied to AES) was also standardized in RFC
     7539.
