Verify wc3 cd key

[Strilanc]

I'm looking for source code to verify that a wc3 cd key will be accepted by the installer, in order to catch typos when people enter a key into my hosting bot.

Anyone have a link?

Make one yourself?  It's hard to make a typo in a string that is 26 characters long and has no single proper spelling.

Making one myself would require disassembling the installer, and finding the code which verifies the key. That's a lot of work which may have already been done, which is why I'm posting the request.

That is code for extracting the public/private/product values from a cd key. It is needed for bnet login, and is probably involved in verifying the key, but doesn't actually perform verification.

If you say so.

Would you care to point out the line where they verify the checksum?

[Camel]

If it decodes, it's a valid key. If the product ID matches the product, the installer accepts it. You're only going to know if the public/private IDs match by trying to log in to battle.net.

[Strilanc]

Look at the product id.

I see, so you're saying the product id *is* the checksum. I hadn't considered that part. I figured part of the private key was a checksum.

Thanks.

[Camel]

There's no checksum. The CD key is just 3 DWORDs encoded in to a form a human can type.

Thank you for this bit of information. You just made things a lot easier for me (I'm confused on how CD-Key hashing works). I now have new insight on how to input CD-Key's.

You've got a lot to learn.

You've got a lot to learn.

Could you be more specific?

Not really.  There's a lot of it.

But basically, you don't need to disassemble anything these days.  There is code out there for checking CD-Keys in Python, Java, C, C++, C#, VB.Net, JavaScript, and PHP (at least).

You're also trying to tell Camel how the private, public, and product values work.  He's got significantly more experience with this stuff than you do.

[Imperceptus]

Correct me if im wrong, but weren't the keys that work generated and stored, amongst those a % of them flagged to be accepted on bnet? 

[MysT_DooM]

Theres a formula that battle.net uses to check to see if the private value given equates to the Prod/Public formula.  If the private value isn't the right answer then you get hit with an invalid key. (Different from wrong product)

Nothing is stored.  The server will see whether or not your private values equate correctly to the prod/public values given.
