BNet Chat bot?

But I don't get how I'm supposed to generate it =/

Also, in SID_AUTH_CHECK, when It refers to 'EXE Version' and 'EXE Hash', what file is EXE? The hash exe file?

[Barabajagal]

GetTickCount works... or 123456... or anything you want. When I say it's generated by the client, I mean it. It can be any value from 0x00000000 to 0xFFFFFFFF.

And yes. The EXE file. Doesn't MBNCSUtil do that for you?

[Ozzapoo]

Alright, I got it, but when I try to get the 'Key Private' using MBNCSUtils, it returns a 10-byte array, but it's supposed to fit in a DWORD?

Also, in SID_AUTH_CHECK, is '(DWORD) [5] Hashed Key Data' supposed to have the values hashed using the 'Broken SHA-1' thing?

Warcraft 3 style CDKeys have a 10 byte private value instead.
The array of 5 dwords in SID_AUTH_CHECK is the resulting 20-byte (suprise!) hash of the cdkey values and the tokens.

You don't actually use the private for anything though.  You'd use .Product and .Value1 on the CdKey object.

Yes, hashed key data is the 20-byte hash returned by cdKey.GetHash(clientToken, serverToken).  It does not need to be converted to integers first; you can simply insert the byte array using .InsertByteArray() if you're using the DataBuffer/BncsPacket classes.

[Ozzapoo]

So I can just use CdKey.GetHash(ClientToken,ServerToken) and put that result as the [5] DWords?

[Ribose]

Yeah,
C#:

Code Select Expand

CdKey key = new CdKey(variablecontainingkeyasstring);
byte[] hash = key.GetHash(clientToken, serverToken);
...
packet.InsertByteArray(hash);
VB.Net:

Code Select Expand

Dim key As CdKey = New CdKey(variablecontainingkeyasstring)
Dim hash() As Byte = key.GetHash(clientToken, serverToken)
...
packet.InsertByteArray(hash)

[MyndFyre]

Yeah,
C#:

Code Select Expand

CdKey key = new CdKey(variablecontainingkeyasstring);
byte[] hash = key.GetHash(clientToken, serverToken);
...
packet.InsertByteArray(hash);
VB.Net:

Code Select Expand

Dim key As CdKey = New CdKey(variablecontainingkeyasstring)
Dim hash As Byte() = key.GetHash(clientToken, serverToken)
...
packet.InsertByteArray(hash)

Actually for VB it'd be:

Code Select Expand


Dim hash() As Byte = ...


[Ribose]

Edited, then.

[Ozzapoo]

Wait hold on...
(DWORD) [5] Hashed Key Data
Shouldn't that be 24 bytes? Or is the [5] the length?

A DWORD is four bytes long.  5 is the length of the array.  5 time 4 is 20.  Therefore the correct number of bytes is 20.

[Ozzapoo]

The data that should be hashed for 'Hashed Key Data' is:
Client Token
Server Token
Key Product (from decoded CD key)
Key Public (from decoded CD key)
(DWORD) 0
Key Private (from decoded CD key)

Then why are there six values to hash?

[Hdx]

You shove all those into a xSHA-1, and the digest is the 5 dwords you send.
You can have unlimited ammounts of data in a SHA1 hash, and the digest will always be 20 bytes

[Ozzapoo]

Arlight....Well I think I got the basics right, but now when I connect it gives me the old product version error -.-

P.S. Hdx, congrats on 1000th post!
