Why this list
In mine opinion if you buy something you should own it and be able to do with it whatever you want to do with your own hardware. More and more you see that if you buy something there is some kind of EULA that forbids you to reverse engineer of do things with it that the original producer isn’t happy about. In my world this should still be legal but more and more there is pressure to ban these keys. As you see below some keys are just a number, so companies want to make some numbers illegal to publish. Here is a handy list for illegal numbers, if you find one missing please let me know and I will add this to this list.
