- * \file chacha20.h
- *
- * \brief   This file contains ChaCha20 definitions and functions.
- *
- *          ChaCha20 is a stream cipher that can encrypt and decrypt
- *          information. ChaCha was created by Daniel Bernstein as a variant of
- *          its Salsa cipher https://cr.yp.to/chacha/chacha-20080128.pdf
- *          ChaCha20 is the variant with 20 rounds, that was also standardized
- *          in RFC 7539.
