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. WebA hash function is often a component of many cryptographic algorithms and schemes, including digital signature algorithms, Keyed-Hash Message Authentication Codes (HMAC), key-derivation functions/methods and random number generators. A hash function operates by taking an arbitrary, but bounded length input and generating an output of fixed length.
