OTOH, if anyone else has come up with a scheme that is hard to break / unbreakable, *please* come formward and correct me. I have a few applications that I'd like to apply this to. :)

The only method I have heard (and this is merely hard to break) is to put the hash value in a dongle. Then everyone will hate your program. Another method that could provide interesting results is to throw code in that will cause the program to function *differently* if hacked. I'm thinking of (I think- correcttions wecome) AutoCad, which was dongled and hacked, but the hack caused some math funciton or another to return erroneous results. This is just obfusification, but could give a hacker some major headaches. -j -- "Blah Blah Blah" ___________________________________________________________________ Jamie Lawrence <jamiel@sybase.com>
