WebDec 10, 2015 · A cryptographic hash function is an algorithm that takes an arbitrary amount of data input—a credential—and produces a fixed-size output of enciphered text called a hash value, or just “hash.” That enciphered text can then be stored instead of the password itself, and later used to verify the user. Cryptographic salts are broadly used in many modern computer systems, from Unixsystem credentials to Internet security. Salts are closely related to the concept of a cryptographic nonce.
