New Auth System on battle.net?

[Logitech]

Can I just check, you send 0x1A after you receive 0x50, right?

Can I just check, you send 0x1A after you receive 0x50, right?

You can send it whenever you like

Sending it after that is the ideal time to send it...so yes.

BNLS_VERSIONCHECKEX2 requires
(STRING) Version check archive filename.

Ohh, ok I didn't see that thought you still had to send the xx values(lockdown-IX86-xx.mpq). But it still didn't work, here is a full log(BNLS_CDKey removed).

Only the ones at the end? If so, I just fixed that and now it is returning 0x203(Wrong product) any idea why on that one? Also is the ValueString always 16 bytes?

I kept refreshing the page and got cd-key hashing failed... Why different returns? Must be doing something wrong?

Well, on BNLS, it says:

Code Select Expand


(DWORD) Product ID.*
(DWORD) Flags.**
(DWORD) Cookie.
(ULONGLONG) Timestamp for version check archive.
(STRING) Version check archive filename.
(STRING) Checksum formula.

And when we compare it with your packet log:

Code Select Expand


3f 00 1a 02 00 00 00 00 00 00 00 06 b9 b5 50 00 ?.............P.
09 ef c0 72 fc c6 01 6c 6f 63 6b 64 6f 77 6e 2d ...r...lockdown-

3f b5 0a 9c 15 dd 94 76 70 25 f6 ce ea 00 00    ?......vp%.....

You can see that BNLS wasnt reading/useing your supplyed version check string:

Code Select Expand


(DWORD) 02 00 00 00       ....
(DWORD) 00 00 00 00       ....
(DWORD) 06 b9 b5 50       ...P
(ULONGLONG) 09 ef c0 72 fc c6 01      ....r...
(STRING) 6c 6f 63 6b 64 6f 77 6e 2d 49 58 38 36 2d 30 33 2e 6d 70 71 00   lockdown-IX86-03.mpq.
(STRING) 00    .

~~~ extra/over flow ~~~
(STRING) 29 e8 27 3f b5 0a 9c 15 dd 94 76 70 25 f6 ce ea 00    ).'?......vp%....
(STRING) 00      .

So just useing 1 null byte to terminate the string, rather than 2, will make it fall into place.

Aside from that, if your now getting 0x203 back in 0x51, then your passing the version check for bnet to be going onto the cdkey check
Now your next task would be, to try a differnt cdkey, check the cdkey is being decoded/handled/hashed correctly.

I suppose if they designed the server to be strict like say, Battle.net, then sure, but I think their intention is to be user friendly and not worry about extra moot

I guess , I was a little supprised BNLS sent him a result back, when the check version string was blank.
Or maybe it did, and he's parseing the responce as success all the time

[Jaquio]

Have tried W2BN,STAR and SEXP... None work all say wrong product. So I guess I have another problem to work out...

Think how the server reads the message, from start to finish:

Then for each cdkey:

Failed. No current products have a cdkey with 17 characters


[Jaquio]

Heh, don't know why I am having trouble with this.. I got my VB bot working just fine, it's my PHPBot giving me problems.. I never used the keylength dword in 0x51 ever... But I added it in there and got a return of 0x101 again. Better then 0x203 I guess.. I am about to give up, because I cannot figure it out.

Heh, it was that 'unknown(0)' tid-bit. Not sure why it was there, I removed it but still 0x101..

My 0x51, lol pretty shitty I know... But oh well. Just want it to work! Lol

Assuming you are getting your CD-key data from BNLS, the blob that BNLS sends back to you should include the length of the CD-key, and you should not be sending that to Battle.net in addition to another field including the CD-key length.

The BNLS protocol specification includes details on where the blobs sent back by BNLS should be used when communicating with Battle.net.  It should be your first choice when troubleshooting problems like this.

I have the same Problem, I always get an invalid version error.
What do I have to send to bnet Server on 0x51 now?

BnetDocs say:
(DWORD)       Client Token (Generates BNLS in BNLS_CDKEY)
(DWORD)       EXE Version (Generates BNLS in BNLS_VERSIONCHECKEX2)
(DWORD)       EXE Hash (Generates BNLS in BNLS_VERSIONCHECKEX2)
(DWORD)       Number of keys in this packet (1)
(BOOLEAN)    Using Spawn (0)
(DWORD)       Key Length (13)
(DWORD)       CD key's product value (1 = Starcraft)
(DWORD)       CD key's public value (How can I calculate this? I copy and pasted it of my packet sniffer)
(DWORD)       Unknown (0)
(DWORD[5])    Hashed Key Data (Generates BNLS but BNLS Spec says DWORD[9] instead DWORD[5]!!?? I noticed, that blizzard removed the exe String)

(STRING)     Exe Information (seems to be removed)
(STRING)     CD Key owner name (ThePro)

1.) Do I just have to copy the result of BNLS_CDKEY (DWORD HashedKeyData[9]) into SID_AUTH_CHECK and send it to bnet?
2.) Where do I have to use the VersionCheckStatstring returned by BNLS_VERSIONCHECKEX2?

[Skywing]

The four cleartext and five digest ulong values are all included in the blob returned from BNLS, which contains all the CD-key related data you need to send to Battle.net.  You should not duplicate any of this information in your SID_AUTHCHECK request; simply include the CD-key blob "as-is" with your SID_AUTHCHECK request.  The only CD-key related data that you must supply are the count of CD-key blobs and the spawn/retail flag.

"Exe Information" and "VersionCheckStatstring" are synonomous in this particular context.  "Exe Information" is the string value returned by BNLS_VERSIONCHECKEX2.
