WebNov 26, 2024 · Hash Functions: Basically, the process of using a given hash function to produce a transaction is called hashing. A hash function, will take any transaction or data input and rehash it to produce an output of a fixed size. The transaction output of that given hash function is what we call a hash. This complete process is known as Hashing. 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 index a … 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.
