Struct Chctr2 

pub struct Chctr2<Aes: AesCipher> { /* private fields */ }

Generic CHCTR2 cipher parameterized by AES key size.

Implementations

impl<Aes: AesCipher> Chctr2<Aes>

pub const KEY_LENGTH: usize

Total key length in bytes (two AES keys).

pub const SINGLE_KEY_LENGTH: usize = Aes::KEY_LEN

Single AES key length.

pub const BLOCK_LENGTH: usize = BLOCK_LENGTH

AES block length in bytes (always 16).

pub const MIN_INPUT_LENGTH: usize = BLOCK_LENGTH

Minimum input length in bytes.

pub fn new_split(key1: &[u8], key2: &[u8]) -> Self

Initialize CHCTR2 from two separate keys.

pub fn encrypt( &self, plaintext: &[u8], tweak: &[u8], ciphertext: &mut [u8], ) -> Result<(), Error>

Encrypt plaintext to ciphertext using CHCTR2.

pub fn decrypt( &self, ciphertext: &[u8], tweak: &[u8], plaintext: &mut [u8], ) -> Result<(), Error>

Decrypt ciphertext to plaintext using CHCTR2.

impl Chctr2<Aes128>

pub fn new(key: &[u8; 32]) -> Self

Initialize CHCTR2-128 from a combined key (K1 || K2).

impl Chctr2<Aes256>

pub fn new(key: &[u8; 64]) -> Self

Initialize CHCTR2-256 from a combined key (K1 || K2).
