Data Authentication Algorithm (DAA) implemetnation as defined in the FIPS 113.

WARNING! The algorithm is not considered secure by today's standards. DO NOT USE it if you don't have to be compatible with legacy software!

Examples

use daa::{Daa, Mac};

// test from FIPS 113
let key = [0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF];
let mut mac = Daa::new_varkey(&key).unwrap();
mac.input(b"7654321 Now is the time for ");
let correct = [0xF1, 0xD3, 0x0F, 0x68, 0x49, 0x31, 0x2C, 0xA4];
mac.verify(&correct).unwrap();
