comment What size should the HMAC key be with SHA-256?
@otus - I don't understand "Also, even keys longer than the hash length can give extra security (because the padded keys differ)". If the key is > hash length it is pre-hashed to the hash length prior to padding, so you can just attack keys of the hash length rather than the original key...
