A hashing algorithm is a function that converts any input data into a fixed-length output known as a hash. It doesn’t matter whether the input is a single letter, a page from a novel, or an entire set of encyclopedias. Each input will produce a unique output expressed as an alphanumeric string of uniform length.

A hash function is any function that can be used to map data of arbitrary size to fixed-size values, though there are some hash functions that support variable length output. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. The values are usually used to … See more A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application.
