An AEAD extension for Cipher

Required methods

fn seal(
    &self,
    buf: &mut [u8],
    plaintext_len: usize,
    ad: &[u8],
    key: &[u8],
    nonce: &[u8]
) -> Result<usize, Box<dyn Error + 'static>>

AEAD-seals plaintext_len bytes in-place in buf together with ad using key and nonce and returns the ciphertext length

fn seal_to(
    &self,
    buf: &mut [u8],
    plaintext: &[u8],
    ad: &[u8],
    key: &[u8],
    nonce: &[u8]
) -> Result<usize, Box<dyn Error + 'static>>

AEAD-seals plaintext into buf together with ad using key and nonce and returns the ciphertext length

fn open(
    &self,
    buf: &mut [u8],
    ciphertext_len: usize,
    ad: &[u8],
    key: &[u8],
    nonce: &[u8]
) -> Result<usize, Box<dyn Error + 'static>>

AEAD-opens ciphertext_len bytes in-place in buf together with ad using key and nonce and returns the plaintext length

fn open_to(
    &self,
    buf: &mut [u8],
    ciphertext: &[u8],
    ad: &[u8],
    key: &[u8],
    nonce: &[u8]
) -> Result<usize, Box<dyn Error + 'static>>
