RustCrypto: crypto_secretbox
crypto_secretbox is an authenticated symmetric encryption cipher
amenable to fast, constant-time implementations in software, combining either the
Salsa20 stream cipher (with XSalsa20 192-bit nonce extension) or
ChaCha20 stream cipher with the Poly1305 universal hash function,
which acts as a message authentication code.
This algorithm has largely been replaced by the newer IETF variant of
ChaCha20Poly1305 (and the associated XChaCha20Poly1305) AEAD
ciphers (RFC 8439), but is useful for interoperability with legacy
NaCl-based protocols.
