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. Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. …
