CD-Key Generator Discussion

[Lenny]

Is it possible to calculate the probability a generated key will work on Battle.net?

[hismajesty]

Yes, since there is a probability for virtually everything in one form or another- Though I do not know the equation. Maybe one of the smarter members do?

[Camel]

The idea is to get Value1 to match Value2. Both are DWORDs, so the probability is 1 in 2^32, or ~4.29 billion. Effective, no?

[iago]

Assuming you generated it from the public algorithm, there is a probability somewhere on the internet, search for the generating algorithm and it should turn up.

[edit] iirc, it was very low, <1%

[Adron]

The best way of generating keys that I am aware of gives you a 0.1% probability of success.

That sounds right..

I agree with those guys... probably about 0.1%. You'd have to spend a lot of time to do that... If you were bored you could use Yoni's Google Calculator to figure it out

!~!HaZaRD!~!

[Adron]

Well, assuming there's no pattern that you can find, I'd say the probability is exactly 0.1%

Edit: My statements in this thread are valid for SC/BW keys, because those are the ones I've generated.

Would jsut using a code such as rand(1000000000000, 5000000000000)

work or do you have ot have it add and substract numbers and stuff along with that?   Whats the best method to do it (make a generator)

[DarkMinion]

With starcraft keys, you could generate keys starting at 1000000000000 and incrementing up, then testing to see if they're valid for install, then testing on battle.net.

Of course, between the IP bans for invalid keys and the time used to generate all the keys, it would probably take you around 6 months to generate one usable key, and then there is a high probability that it is already in use.

So, in other words, forget it, you won't be able to do it.

[UserLoser]

Because I was curious, I did something with the public DecodeCDKey function out there, hoping I could find a pattern somehow to actual working CDkeys on Battle.net [never tried to figure anything out].  I ran a "bruteforce" like program starting at 0000000000000 up to 3999999999999.  If the number passed the function, it'd output it to a file.  You can find my results at http://darknet.darktech.org/test/keys.txt - 39MB file, I did stop it after a while, it tended to make my computer run just a bit slow.

[Adron]

It would probably do you more good to just study the code... It's not all that hard to look at it and understand how a cd key is made up, and how to convert cd keys between different representations.

[UnderCover]

so i tihnk if you did a code where youget a rand number then add 2 to a digit then substract form a digit etc etc  does anoyne else have any suggestions


Also how would i test the cd keys could i make a online cd key tester thorugh php  I love php

[Camel]

Well, considering testing a cd key doesn't require a persistant connection to battle.net, it may actually be feasable to connect with php. Perhaps you could write a PHP extention (dll) to assist with hashing/checkrevision?

[UnderCover]

perhaps  amybe there is a way a can connect through sockets...

how would i send and recieve data thorugh them does anyone else ebsides me know php?
