Actually 'nonce' is used for the introduction of a one time random value
that may or may not be public. A 'salt' is a long term repeated use value,
commonly used in association with password verification, it is public, and
it's use is simply to make dictionary attacks harder. 'Randomizer' is
basically unused, so it would be acceptable, but I would prefer 'nonce'.
