Trait Implementations

impl Cipher for ChaCha20Poly1305

const KEY_LEN: usize

Byte size of a key.

const NONCE_LEN: usize

Byte size of a nonce (aka initialization vector, or IV).

const MAC_LEN: usize

Byte size of a message authentication code (MAC).

fn seal(message: &[u8], nonce: &[u8], key: &[u8]) -> CipherOutput

Encrypts message with the provided key and nonce.

fn open(
    output: &mut [u8],
    enc: &CipherOutput,
    nonce: &[u8],
    key: &[u8]
) -> Result<(), MacMismatch>

Decrypts encrypted message with the provided key and nonce and stores the result into output. If the MAC does not verify, returns an error.

impl Clone for ChaCha20Poly1305

fn clone(&self) -> ChaCha20Poly1305

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for ChaCha20Poly1305

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.
