Cipher operations

Required methods

fn name(&self) -> &'static str[src]

The string that the Noise spec defines for the primitive

fn set(&mut self, key: &[u8])[src]

Set the key

fn encrypt(
    &self,
    nonce: u64,
    authtext: &[u8],
    plaintext: &[u8],
    out: &mut [u8]
) -> usize[src]

Encrypt (with associated data) a given plaintext.

fn decrypt(
    &self,
    nonce: u64,
    authtext: &[u8],
    ciphertext: &[u8],
    out: &mut [u8]
) -> Result<usize, ()>[src]
