Who told you MFC is an encryption library? :-)

Solution 1

Without more specific detail it's impossible to offer much more than suggesting these links[^], and this MSDN section[^].

Good place to start, my 5.
I would also add Wikipedia articles on the principles. From CodeProject questions, I can see that understanding of how it all works is a bigger problem then using any particular libraries or APIs. -- Please see my answer.

Just in case, in addition to useful referenced by Richard (Solution 1), I want to add the articles on the public-key cryptography. It's also important to understand the nature of a one-way function, the reasons for cryptographic strength of those algorithm and the logic behind key exchange and use. Unfortunately, many beginners in this field try to use it without understanding of the essence of things, and it makes the effort totally useless.

Please see:
