   Library:		Win32.

   Version:    1.00

   Usage:      Rijndael (pronounced rain-dahl) is the block cipher algorithm 
               that has been selected by the U.S
	
   Notes:		I only use the 16 Bytes Block Encryption 


   Method(Public)       Description
   ------------------   --------------------------------------	
   MakeKey              The Encrytion Key (or password)
   EncryptBlock         Encrypt a string.
   DecryptBlock         Decrypt a string
