- ChaCha20 cipher algorithm, RFC7539.
+ The ChaCha20 and XChaCha20 stream cipher algorithms.
ChaCha20 is a 256-bit high-speed stream cipher designed by Daniel J.
Bernstein and further specified in RFC7539 for use in IETF protocols.
- This is the portable C implementation of ChaCha20.

+ This is the portable C implementation of ChaCha20. See also:
<http://cr.yp.to/chacha/chacha-20080128.pdf>
+ XChaCha20 is the application of the XSalsa20 construction to ChaCha20
+ rather than to Salsa20. XChaCha20 extends ChaCha20's nonce length
+ from 64 bits (or 96 bits using the RFC7539 convention) to 192 bits,
+ while provably retaining ChaCha20's security. See also:
