Hey Chad,

Have a look at this:

http://www.codeproject.com/cpp/AESProductKey.asp

I'm using crypto++ with a wxWidgets app now (although not exactly the
above), which works nicely.

Hope it helps,
Gian

From: Leslie Newell on
If you use a commercial protection system, remember that crackers will
already know it operates and the best ways to crack it. Spend plenty of
time searching the internet for ideas, design your own solution and
_tell no-one about how it works_!

No matter how good your system is, it will be possible to crack it. You
just need it to be difficult enough that your average cracker will give
up. Unless your app becomes very popular, the experts won't bother to try.
