WebPepper (cryptography) In cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, such as a Hardware Security Module. [1] 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.
