Have a copy of my CD Hash, thanks to rec0's app. I was wondering if there was anyway to convert that into my CD key? Could save me a lot of trouble as well as save me a few bucks... Would like to play this game again you know. :)

There isn't. If you could do that then piracy would be WAAAAY more rampant. If you have the game installed somewhere still though, you can use a tool (forget its name, but I think it was made by TheGhost) to recover your key from the registery.

That's not the CD Hash though.

The great thing about a hash is...it's one way and still unique and cannot be reversed unless brute forced.

You could try rainbow tables since the hash is not salted BUT it's very unlikely it's going to work since the original string is very long. I don't even know if just the pure CD Key is digested in the first place.

If you want to read more about hashes... I know it's badly written. (http://www.vivid-abstractions.net/programming/understanding-hashes-for-beginners/)

i remember rec0 did make a program to get the keys from the hashes, but for obvious reasons never released it.

rec0 cannot have made a program that reverses a hash. Like I said, it's only possible one way unless he made a program that brute forces and maybe has an installed filter for Halo keys but even then it would take a lot of time to just reverse one hash.

afaik the CD Hash is a MD5 digest of the original key (or just part of it). Maybe Korn can shed some light on this.

Yea I remember there being a discussion about that. Too bad I never got a copy, would have been a total life saver haha. Guess I'll either have to wait until I back home in four months or pony up a few bucks to another copy...

The above link is legit. When you go to the site you'll see 13 copies of the game in the picture. There were originally 14. I took the first one :D At $10, you can't go wrong.

I remember talking with rec0 a bit about that as well, but at the time I was trying to get him to make the team icon hack for the CE videos or something??

I don't doubt that he found a way to reverse the hashes, but the speed of our hardware back then would surely have been an issue. Works in theory, but you'd end up dying because it took so long in practice... rec0 nooooooooo... :ohdear:

That guy would be me. Amit was the the first person I sold a "CD-Key fresh out of a sealed box" in the mean time I've sold 8 keys so far.

As for Hash to CD key, some secrets are meant to be kept for obvious reasons, so don't dig down too deep in the rabbit hole because it gets quite dark and will do us all no good. :ohdear:
Your best bet would be as mentioned, obtain your key from the register. If that fails you have the alternative of purchasing a new CD-Key.

I think i know what the "Hashing" method is for the cd had, When i was making my servertool i thought about it too. But never went anywere and now i can't find out anything cause i don't have a server to get a hash from.

Rec0 did mention something on those lines to me way back, he didnt have it working though, he did have another very handy tool related to it.

I tried to see if it was the same way as a windows product key it made a key but it wasn't correct. So I am going to mess with the way it inputs to try and get it right.

This game would be completely fucked if such a thing existed.

the only problem with me trying to get cdkey's from hash's is i don't have the original keys or any way to test them.

If the hash is a true hash it's fucking impossible...do you guys get it now?

If this is a true hash and rec0 made an app for it it's probably a brute forcer with an installed filter e.g. total length of 26 chars, first 2 are always letters etc.
