Hash functions are extremely useful and appear in almost all information security applications.

A hash function is a mathematical function that converts a numeric input value into another compressed numeric value. The input data for a hash function has an arbitrary length, but the output data always has a fixed length.

The values returned by a hash function are called message digest or simply hash values .
