Type Definition crypto_secretbox::XChaCha20Poly1305

pub type XChaCha20Poly1305 = SecretBox<ChaCha20>;

Available on crate feature chacha20 only.

crypto_secretbox instantiated with the XChaCha20 stream cipher.

NOTE: this is a legacy construction which is missing modern features like additional associated data.

We do not recommend using it in greenfield applications, and instead only using it for interop with legacy applications which require use of the crypto_secretbox construction instantiated with XChaCha20.

For new applications, we recommend using the AEAD_XChaCha20_Poly1305 construction as described in draft-irtf-cfrg-xchacha. An implementation of this IETF flavor of XChaCha20Poly1305 can be found in chacha20poly1305::XChaCha20Poly1305.
