Struct Hctr3 

pub struct Hctr3<Aes: AesCipher> { /* private fields */ }

Generic HCTR3 cipher parameterized by AES key size.

Implementations

impl<Aes: AesCipher> Hctr3<Aes>

pub const KEY_LENGTH: usize = Aes::KEY_LEN

Encryption key length in bytes.

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(key: &[u8]) -> Self

Initialize HCTR3 cipher state from an encryption key.

Derives a secondary authentication key (Ke) from the encryption key for the two-key construction.

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

Encrypt plaintext to ciphertext using HCTR3.

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

Decrypt ciphertext to plaintext using HCTR3.
