win form app实现了DES算法的S盒？ [英] win form app that implements S-boxes of DES algorithm ?

问题描述

我有一个项目在win form应用程序中实现使用 DES（数据加密标准）的方框..



如果有人可以帮我提出一些想法，或希望告诉我一些对我有用的有用代码行......

ps：我不需要所有的des算法，如何s框工作并以win形式实现应用





问候

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

推荐答案

如果您在此处阅读此前几段（直到另请参阅）： http：/ /en.wikipedia.org/wiki/S-Box [ ^ ]你会确切地知道该做什么。



你想要什么样的S-Box BTW？一个6 x 4或什么。请注明，考虑一下，如果你还有问题，请给我留言，我会看看我能为你做些什么。



提示： S-Box是一个nxm矩阵。实际上这使它成为C＃术语中的nxm数组。



快乐编码！

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!
