well, the source is only includes key->hex function, its fully rewritten from arma2oa setup file, they are using same char packing for all other dlc/addons.

you can also use it to restore your key from registry if you forgot it, it will show up your key.

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

yeah, GUID does looks like MD5 hash, i did not reversed GUID  generation algo, but i think it is not revesible, i might look at it later.

ID != GUID

Neither ID or GUID is reversible anyway. (By that I mean, you can't get a key from either of them)

inf1 i just tryed didnt worked

You still need a valid key.

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
