Newest MBNCSUtil bits

[MyndFyre]

This is not an official release.

I'm not quite sure that anyone wants these yet, but here's the latest info on MBNCSUtil.....

I've finally gotten around to working on Lockdown.  I'm about 70% complete porting the C code from rob into C#.  Presently, this *only* works with unsafe code, because there is a LOT of pointer math going on, and I'm way too lazy to move over to streams when I can just do the pointer math.

There's still a lot to be learned for anyone who might be interested - primarily in working with unmanaged memory, using unmanaged pointers to access structure data, and the like. 

It's now hosted on subversion, at https://svn2.hosted-projects.com/robpaveza/mbncsutil.  You can check out the code anonymously with the username mbncsutil_anonymous, no password.  There is also a Trac wiki online with access to post tickets, view the project roadmap and browse source; it's located at https://www2.hosted-projects.com/trac/robpaveza/mbncsutil.  There is also a subversion browser integrated into Trac, if you've never used it.
(You can log in with the same username).

New items in the latest bits include the /Util folder, an entirely-internal namespace dealing with the involved processing and unmanaged memory use.  Additionally, COM support has been removed officially from version 2.0 of MBNCSUtil - it was primarily meant as a learning experience for me, and I learned what I wanted to learn.  Finally, if anyone had used a prior beta of MBNCSUtil v2.0, the BnFTP namespace has been renamed to Net, so you now create MBNCSUtil.Net.BnFtpVersion1Request.

MPQ support is currently missing from the bits online, but will be there by the weekend.

If you would like to contribute to this project, please contact me with your experience and what you think would be relevant.

By the way: you may notice that 'rob' checked in these files.  That's me, not the other rob on the forum.

Anyone wanting to take a fun crack at fixing this, the lockdown implementation is completed, but not working.  (For those of you wishing to point out the irony in that statement, I mean that it doesn't crash, but it also doesn't result in the correct value).

The good news is that I seem to clean up all my pointers and the like. 

I'm testing againt rob's code (posted here).  Here's what he gets:

Lockdown file: c:\GameFiles\STAR\lockdown-IX86-08.dll
Checksum: 7afbfff8
Version: 10f0100
Digest: ead0367b2ce7f080b0cbe2f573d3c713

Here's what I get:
Checksum: a5d6cf16
Version: 010f0100 (correct)
Digest: d0 b7 d9 d7 15 6a 73 69  48 3f 3e 33 53 8d 85 87

I corrected a TON of errors in Sha1Transform() but that was just on the first pass of Sha1Update().  I haven't gotten to look at too much else; I've been working on this WAY too late.

Stuff can be checked out at the SVN repo listed above - be sure to check out both /trunk and /branches.  If you correct it, please compile a .patch and let's see what you have!

In terms of the SHA1 implementation, I've been told that it's identical to the real one, except that sha1_final() adds that "80 00 00 00 00..." thing to the buffer. If that's true, then a simple wrapper around the standard library would solve everything.

[warz]

Yup. From what I can remember, it's a standard SHA1 implementation, with a few small changes to the sha1_final function.

I've now gotten mine and rob's code to return the same values for the above values.  Now I'm getting vercheck 0x0101 INVALID_VERSION from SID_AUTH_CHECK.  Here's a packet capture with my cd key info removed:

MBNCSUtil v2.0.3.15 Beta 1 is now available at release.  Here are the release notes:

• Lockdown CheckRevision is now supported for Starcraft and Warcraft II: Battle.net Edition. This is a pre-release version of MBNCSUtil 2.0 that previews the MPQ, BnFTP, and Lockdown Checkrevision functionality of MBNCSUtil 2.0. Tests indicate that Lockdown currently incorrectly calculates the revision check 7.4% of its uses.
• IMPORTANT - MBNCSUtil 2.0 does not support the .NET Framework 1.x; clients that wish to use MBNCSUtil 2.0 should target the .NET Framework 2.0.
• MBNCSUtil is now hosted in a Subversion repository. Point your favorite SVN client at https://www2.hosted-projects.com/robpaveza/mbncsutil/trunk/ to download the latest bits. (Note that the SVN repository is updated much more frequently than the stable build list; for stable builds, be sure to download the software from the official site. Along with Subversion, there is now a Trac wiki and bug tracker. Visit it at https://www2.hosted-projects.com/trac/robpaveza/mbncsutil. Both Subversion and Trac require authentication; use the username mbncsutil_anonymous with no password.
• MBNCSUtil 2.0 includes the ability to open MPQ archives! See the MBNCSUtil.Data namespace for implementation details. If you retrieve the solution from Subversion, you will find a project called mmpq in the trunk; this project demonstrates opening an MPQ and retrieving its listfile.
• MBNCSUtil 2.0 includes an integrated ability to download files from Battle.net via the proprietary BnFTP protocol. See the MBNCSUtil.BnFtp namespace for implementation details. If you retrieve the solution from Subversion, you will find a project called mbnftp in the trunk; this project demonstrates downloading files from the BnFTP service.

So are you going to tell us what was wrong?

Seriously though, mostly just some typos in the port from C.

I should have reported that in trac.

MBNCSUtil v2.0.3.16 Beta 1 Service Release is now available for download.  Release notes:

• A bug was identified in the way the LockdownHeap class (part of the MBNCSUtil.Util namespace, which is not a public namespace) was marshaling data to the unmanaged heap, which was cauing 100% failure rates on lockdown. This issue has been corrected. Please note that the downloadable documentation file has not been updated for this service release, as the API has not changed.
