## Overview

Besides some low level IDEA encryption routines, the IDEA unit also offers 2 streams which offer on-the-fly encryption or decryption: there are 2 stream objects: A write-only encryption stream which encrypts anything that is written to it, and a decription stream which decrypts anything that is read from it.
