Available on crate feature use-chacha20poly1305 only.

type Key = Sensitive<[u8; 32]>

Type of key.

fn name() -> &'static str

Name of this cipher function.

fn encrypt( k: &Self::Key, nonce: u64, ad: &[u8], plaintext: &[u8], out: &mut [u8], )

AEAD encryption.

fn encrypt_in_place( k: &Self::Key, nonce: u64, ad: &[u8], in_out: &mut [u8], plaintext_len: usize, ) -> usize

AEAD encryption, but encrypt on one buffer. return the length of ciphertext.

fn decrypt( k: &Self::Key, nonce: u64, ad: &[u8], ciphertext: &[u8], out: &mut [u8], ) -> Result<(), ()>

AEAD decryption.

fn decrypt_in_place( k: &Self::Key, nonce: u64, ad: &[u8], in_out: &mut [u8], ciphertext_len: usize, ) -> Result<usize, ()>

AEAD decryption, but decrypt on one buffer. return the length of plaintext.

fn key_len() -> usize

Length of key.

fn tag_len() -> usize

Length of auth tag.

fn rekey(k: &Self::Key) -> Self::Key

Rekey. Returns a new cipher key as a pseudorandom function of k.
