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.
A random serial number generator, see also wordserial/word. Used in cases where a manufacturer of a program can ban certain serial numbers from working on its program.
Keygen is abbreviation of CD KeyGenerator. It can generate serial of a commercial program like Photoshop. Try not to download keygens because they are powered by viruses to generate CD keys. Some keygens are fake, they are just a random number generator.
I searched the serial of Photoshop on Google because keygens contains Trojanviruses.

KeyGen's are very helpful when you are close to being suicidal and just need a little more motivation.
It's like jumping off a building. Jumping off the building doesn't kill you. Landing on the ground kills you.
Don't attempt if you're not suicidal extremely deadly.
