Description

Implementation of the Counter mode (CTR).

This cipher mode works like a stream cipher with a block size >= 1. This means that the same key and initialization vector (aka counter) should never be reused, since a simple xor would reveal information about the plain text. It also means that it should never be used without a suiteable Message Authentication Code (MAC).
