RustCrypto: CBC-MAC
Generic implementation of Cipher Block Chaining Message Authentication Code (CBC-MAC).
WARNING! The algorithm has known weaknesses in case of variable-length messages. See the linked Wikipedia article for more information.
Examples
use cbc_mac::{digest::KeyInit, CbcMac, Mac};
use des::Des;
use hex_literal::hex;
// CBC-MAC with the DES block cipher is equivalent to DAA
type Daa = CbcMac<Des>;
// test from FIPS 113
let key = hex!("0123456789ABCDEF");
let mut mac = Daa::new_from_slice(&key).unwrap();
mac.update(b"7654321 Now is the time for ");
let correct = hex!("F1D30F6849312CA4");
mac.verify_slice(&correct).unwrap();
