ChaCha20 and XChaCha20 stream ciphers go library
The ChaCha20 stream cipher ChaCha is a stream cipher family created by Daniel J. Bernstein. The most common ChaCha cipher is ChaCha20 (20 rounds). ChaCha20 is standardized in RFC 7539 (https://tools.ietf.org/html/rfc7539).
This package provides implementations of three ChaCha versions: - ChaCha20 with a 64 bit nonce (can en/decrypt up to 2^64 * 64 bytes for one key-nonce combination) - ChaCha20 with a 96 bit nonce (can en/decrypt up to 2^32 * 64 bytes ~ 256 GB for one key-nonce combination) - XChaCha20 with a 192 bit nonce (can en/decrypt up to 2^64 * 64 bytes for one key-nonce combination)
Furthermore the chacha subpackage implements ChaCha20/12 and ChaCha20/8. These versions use 12 or 8 rounds instead of 20. But it's recommended to use ChaCha20 (with 20 rounds) - it will be fast enough for almost all purposes.
