I am trying to create simple a registration key (CD KEY) system for my applications,
I want a the ability to create a private key and lots and lots of public keys from the private key
I would have a dialog box where my users could enter the public key I have generated for them that would get compared to the private key that is embedded in side of my application, if the public key is valid then the program will unlock its self.
I am looking for a tutorial in C/C++ or MFC on creating private/public keys and validating them.
A link will do,
I know close to nothing about encryption
I’m experienced in C\C++\MFC
Thank you for your time and effort
