WebIn 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] WebNote that a salt is not exactly the same as an Initialization Vector for symmetric encryption, where strict requirements like unpredictable uniform randomness typically apply.) A …

WebApr 21, 2015 · 53. Storing the hash of users' passwords, e.g. in a database, is insecure since human passwords are vulnerable to dictionary attacks. Everyone suggests that this is mitigated via the use of salts, but the salt is considered non-sensitive and does not need to be protected. In the event that the attacker has the salt how has his dictionary attack ... WebIn cryptography, a key derivation function ( KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a cryptographic hash function or block cipher ).
