RustCrypto: XSalsa20Poly1305

🚨 DEPRECATED! 🚨

Please switch to the crypto_secretbox crate.

This crate is deprecated and will not receive further updates.

About

XSalsa20Poly1305 (a.k.a. NaCl crypto_secretbox) is an authenticated encryption cipher amenable to fast, constant-time implementations in software, based on the Salsa20 stream cipher (with XSalsa20 192-bit nonce extension) and the Poly1305 universal hash function, which acts as a message authentication code.

This algorithm has largely been replaced by the newer ChaCha20Poly1305 (and the associated XChaCha20Poly1305) AEAD ciphers (RFC 8439), but is useful for interoperability with legacy NaCl-based protocols.
