Struct Hctr3Fp 

pub struct Hctr3Fp<Aes: AesCipher, const RADIX: u16> { /* private fields */ }

Generic HCTR3+FP cipher.

Implementations

impl<Aes: AesCipher, const RADIX: u16> Hctr3Fp<Aes, RADIX>

pub const FIRST_BLOCK_LENGTH: usize

First block length in digits (radix-dependent).

pub const MIN_MESSAGE_LENGTH: usize = Self::FIRST_BLOCK_LENGTH

Minimum message length in digits (same as first_block_length).

pub const BLOCK_LENGTH: usize = BLOCK_LENGTH

AES block length in bytes (always 16).

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

Initialize HCTR3+FP 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 digits to ciphertext digits using HCTR3+FP.

All input digits must be in range [0, RADIX). Output will also be in this range.

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

Decrypt ciphertext digits to plaintext digits using HCTR3+FP.
