here are some numbers that will be of great interest to people ( against my better judgment tbh but )  

Note: they are not offsets but something else it's all im saying about it.

You can't retrieve an key from an ID because it's just a weirdo hash of some characters in the key, non-reversible.

I wrote a key decryption function, too, maybe I'll compare them  :icon_razz2
You realize if it wasn't reversible then BE and BI wouldn't know if your key was valid right?

What?

GUID -> Key
ID -> Key

is not possible.

BI sends gamespy your key and gamespy checks if it's valid, the hashes are generated by the BE server only after that process occurs.

ID and GUID can not be turned into a key in any way.

in fact the game never sends the key to GS in plaintext, only as a hash, so it cant be stolen.
Any hash function or encryption can be reversed, the only thing stopping somebody is time.

one-way hash != encryption
if "one-way hash" meant it couldn't be reversed then there wouldn't be a panic when somebody dumped the user database of a website or forum that stores passwords as md5 or some other hash.

reversible means crypted-data contains original data itself, hash does not contain data, its one-way function, you can just try to randomly (or not) generate data, calculate hash and compare it, thats bruteforce.
key is not a password, its way too big to bruteforce it. key is not a password, its way too long to bruteforce it.

a hd5850 can do several hundred million md5 bruteforce attempts per second. That's a 2 year old GPU that you could get for $100 if you looked around. Newer ones can do much much more. Whether it's bruteforce or reversible, would take the same time regardless. All it would take is somebody to write a program with the hashing function BE uses to calculate the GUID and try keys until you get the same GUID.

The biggest problem with that is mass comparing keys. There's around 4x10^36 keys (Ish, a few trillion either side) and that's a lot to compare.

true, i never said it would be quick, but merely the fact that it's not impossible.
