An executable computer program which is used to illegally bypass copy protection on games and commercial software by generating a random serial number, or "cd key", that matches the software it is intended to be used with. These programs range from very basic to quite complex, and are commonly distibuted along with warez. However, most games with online capabilities can now determine if you are using an invalid key and block you from playing over the Internet.
