I have a project to implement use of s boxes of DES (data encryption standard) in win form application ..

if anyone can help me with some ideas or hopefully to tell me some useful lines of code that would be helpful to me ...
ps: I don't need all the des algorithm , just how s boxes work and implement that in win form app


regards

If you read the first couple of paragraphs of this here (until "See also"): http://en.wikipedia.org/wiki/S-Box[^] you'll know exactly what to do.

What kind of an S-Box do you want BTW? A 6 x 4 or what. Please specify, think about it and if you still have problems with it please leave me a comment and I'll see what I can do for you.

Hint: An S-Box is a nxm matrix. Actually this makes it a nxm array in C# terms.

Happy coding!
