Use this class for getting a MD4 message digest. Create a MD4 and reuse it after a message digest calculation. There can be as many MD4 objects as you want to have multiple calculations same time. The message can be passed in one or a sequenze of parts wrapped in a ByteBuffer to the update of the same MD4 instance. To finish the calculation use final, it will reset the MD4 instance for a new calculation. @author emarant @version $$Revision: 1.1 $$Last changed by $$Author: javajox $$ on $$Date: 2008/07/31 16:44:35 $$
