Trait Implementations

impl Aead for ChaCha20Poly1305

fn name(&self) -> &'static str

Human-readable algorithm identifier (e.g. "AES-256-GCM").

fn key_len(&self) -> usize

Required key length in bytes.

fn nonce_len(&self) -> usize

Required nonce length in bytes.

fn tag_len(&self) -> usize

Authentication tag length in bytes appended to ciphertext.

fn seal( &self, key: &[u8], nonce: &[u8], aad: &[u8], pt: &[u8], ct_out: &mut [u8], ) -> Result<usize, CryptoError>

Encrypt pt and write ciphertext || tag into ct_out.

fn open( &self, key: &[u8], nonce: &[u8], aad: &[u8], ct: &[u8], pt_out: &mut [u8], ) -> Result<usize, CryptoError>

Decrypt and authenticate ct (ciphertext || tag) into pt_out.

fn seal_to_vec( &self, key: &[u8], nonce: &[u8], aad: &[u8], plaintext: &[u8], ) -> Result<Vec<u8>, CryptoError>

Convenience: encrypt and return ciphertext || tag as a Vec<u8>.

fn open_to_vec( &self, key: &[u8], nonce: &[u8], aad: &[u8], ciphertext: &[u8], ) -> Result<Vec<u8>, CryptoError>

Convenience: decrypt and authenticate, returning plaintext as Vec<u8>.

impl Clone for ChaCha20Poly1305

fn clone(&self) -> ChaCha20Poly1305

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChaCha20Poly1305

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ChaCha20Poly1305

fn default() -> ChaCha20Poly1305

Returns the “default value” for a type.
