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. WebCryptographic hash functions play an important role in modern communication technology. The input to a hash function is a file or stream of any size and the output is a fixed-size digital representation of the file that is normally less than 1KB and serves as the fingerprint of the original file (often called the message digest). ... 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. … dgh osinergmin
