A hash function is a function that has the potential to map data of an arbitrary size to values that have a fixed size. The output of a hash function is known as a hash value, hash code, digest, or hash.

The values obtained as output are used to index a fixed-size table, known as hash table. The process of using a hash function to index a hash table is known as hashing or scatter storage addressing.

The goal of a hash function is essentially to guarantee the integrity of a message. With ...
