/**
 * ChaCha stream cipher, released
 * in 2008. Developed after Salsa20, ChaCha aims to increase diffusion per round.
 * It was standardized in [RFC 8439](https://www.rfc-editor.org/rfc/rfc8439) and
 * is now used in TLS 1.3.
 *
 * [XChaCha20](https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-xchacha)
 * extended-nonce variant is also provided. Similar to XSalsa, it's safe to use with
 * randomly-generated nonces.
 *
 * Check out [PDF](http://cr.yp.to/chacha/chacha-20080128.pdf) and
 * [wiki](https://en.wikipedia.org/wiki/Salsa20) and
 * [website](https://cr.yp.to/chacha.html).
