Hello People,

I am a graduate university student who is dealing with implementing a DES algorithm for graduation project, and I wonder if you could spare some information about configuring the basic DES functions without

using System.Security.Cryptography;
kind of prepared classes. The inside of them is actually needed for me for a C# application 
and I am also ready for your offers for the windows form to be used . Please help , thanks a lot.
