Cryptographic functions

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. WebAug 26, 2016 · A cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size alphanumeric string, which is called the hash value (sometimes called a message digest, a digital fingerprint, a digest or a checksum). The most known of them are functions like MD5, SHA1 and SHA2.
