- * The Salsa20/Chacha20 stream ciphers
- * ===================================
- *
- * These are similar stream ciphers by djb.
- *
- * A reduced round variant of Salsa20 (Salsa20/12)
- * was selected as a finalist of the eSTREAM stream
- * cipher competition.  This implementation does
- * the full 20 rounds.
- *
- * ChaCha20 is fundamentally like Salsa20, but
- * has a tweaked round function to improve security
- * margin without damaging performance.
