|
|
* \brief 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.
