Cryptographic salt

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). KDFs can be used to stretch keys into longer keys or to obtain …

WebThe salt is not a cryptographic secret, so storing it in your table is no problem. The only purpose of a salt is to ensure that when different instances of the same item are hashed (or encrypted) that you get a different result. – Michael Burr Oct 8, 2008 at 18:44 3 WebA salt is a unique, randomly generated string that is added to each password as part of the hashing process. As the salt is unique for every user, an attacker has to crack hashes one at a time using the respective salt rather than calculating a hash once and comparing it against every stored hash.
