SecurePlayLibrary::MD5 Class Reference

#include <MD5.H>

List of all members.

Detailed Description

This MD5 class was ported by IT GlobalSecure to C++ from Java, which was written by Harry Mantakos harry@meretrix.com Feel free to do whatever you like with this code. If you do modify or use this code in another application, I'd be interested in hearing from you! -------------------------------------------------------------------------- See http://www.cs.umd.edu/~harry/jotp/src/md.java Written for jotp, by Harry Mantakos harry@meretrix.com

Class for implementing md4 and md5 hash algorithms. There are constructors for prepping the hash algorithm (doing the padding, mainly) for a String or a byte[], and an mdcalc() method for generating the hash. The results can be accessed as an int array by getregs(), or as a String of hex digits with toString().
