Sep 20, 2013 at 11:28 comment added Thomas It's usually even simpler: most "stand-alone software" validation can be defeated by simply hooking into whatever code does the key validation, and replacing it by "this key is valid" (regardless of the key, of course). Unless said key is going to be used at some subsequent point in the program (e.g. as some authentication token for interaction with some remote server), that's it - you've "cracked" the software product, without even caring what validation mechanism was involved. I think you need to detail your specific requirements a bit more.
