Hi Jim, Protecting an exe effectively requires more than encryption - it needs an in depth knowledge of the operating system, reverse engineering tools, and reverse engineering methods.
We make software product called CrypKey Stealth that rewrites an exe in such a way that reverse engineering tools are no longer effective. The best way to describe the security effect is "the exe becomes a 10,000 piece jigsaw puzzle with no picture on the pieces". Contact me if you are interested. Why reinvent the wheel?

He broke it by cracking the executable and skipping over my crypto calls. Does anyone know of a way of using crypto++ to protect the executable that's using it? Thanks, -Jim
