WebApr 13, 2014 · the hash is H n. If we use AES-256, we obtain a 128 -bit hash, with n = ⌊ ( l + 320) / 256 ⌋ AES encryptions (and sub-key derivations) where l is the message length in bits. There are other constructions, but this is the less inefficient we have when using one of the three AES ciphers.
