WebJul 20, 2012 · A salt is not meant to be secret, instead, a salt 'works' by making sure the hash result unique to each used instance. This is done by picking a different random salt value for each computed hash. The intention of the salt is not compromised when it is known; the attacker still needs to attack each hash separately. Web3. Salts must be far more than unique. Salts protect against making a rainbow table, or some other form of pre-computed attack.
