WebJan 5, 2024 · A hash function is an algorithm that transforms data of arbitrary size into a fixed size output. The output is a ciphered text called a hash value or a digest. The main objective of a cryptographic hash function is verifying data authenticity. Hash functions often are used in passwords. WebAn algorithm that computes a numerical value (called the hash value) on a data file or electronic message that is used to represent that file or message, and depends on the entire contents of the file or message. A hash function can be considered to be a fingerprint of the file or message. See Hash function.
