License key system

[NuclearIce]

I'm switching my software over from a method I developed to make sure the software is running on only one computer (not uncrackable or anything, but it would be pointless to aim for that anyway) to a more common method of using license keys and just tracking their usage. I found a great article that talks about a method I'd really like to use (Using OpenSSL for license keys), but the problem is finding a usable RSA function. I already found an RSA plugin by peethebee (on this forum), but his keys aren't standard (as far as I can tell) and I can't figure out how to utilize the OpenSSL library (if anyone could help there, I'd be really grateful) in AutoIt. Does anyone have any other suggestions on practical & relatively secure licensing schemes that could be implemented in AutoIt and PHP (since I want to automate the license key generation process when a purchase is made on my website)? Of course, it doesn't have to be able to be implemented in PHP since I could just write an AutoIt program and call it from PHP. Anyways, I would really appreciate any help anyone has to offer.

Thanks in advance!
