Keygen and Checker C#?

I am trying to implement a license feature in my software, i want to print the key on the CD and the user have to input the key in the system and the key will be validated then, that means that a key generated in the CD have to produce a value after decryption that will match the hard coded value on the software or something like that.

Can somebody please tell me how to implement this kind of the thing or anything that work with the same i idea.

thanks.

  • As an indirect answer, I'd suggest you start by having a read through the answers to this question - it may be that you decide to take another approach to the licensing and protection of your software.
