Digest

This module provides a framework for message digest libraries.

You may want to look at OpenSSL::Digest as it supports more algorithms.

A cryptographic hash function is a procedure that takes data and returns a
fixed bit string: the hash value, also known as _digest_.  Hash functions
are also called one-way functions, it is easy to compute a digest from a
message, but it is infeasible to generate a message from a digest.
