Struct TripleDes 

pub struct TripleDes { /* private fields */ }

Triple DES in EDE (Encrypt-Decrypt-Encrypt) mode.

Uses three independent DES keys (K1, K2, K3). The 24-byte key is split into three 8-byte DES keys.

Trait Implementations

impl BlockCipher for TripleDes

const BLOCK_LEN: usize = 8

Block size in bytes (16 for AES, 8 for DES / 3DES).

const KEY_LENS: &'static [usize]

Key sizes supported by new, in bytes.

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

Initialise the cipher with a key. The key length must be one of the values listed in Self::KEY_LENS.

fn encrypt_block(&self, block: &mut [u8])

Encrypt block in place. The slice must be at least Self::BLOCK_LEN bytes long.

fn decrypt_block(&self, block: &mut [u8])

Decrypt block in place. The slice must be at least Self::BLOCK_LEN bytes long.
