CDKey and Password Hashing

[RealityRipple]

I'm trying to wean my bot off of external DLLs a bit more, and in doing so, I would like to hash CDKeys and Passwords locally in VB. Right now I'm using BNCSutil (which does a wonderful job, btw), but I'd really like to be able to do it internally. Can someone point me towards what I need to have? I know I need a Broken SHA-1 function, and some outline on how to hash and double-hash. Any help would be much appreciated.

Unless there's a Bignum library for VB, I don't think you can.

Would that be of use?

Hrmm I believe that would work but you may want to get a second opinion, but when it comes to vb6 doing your hashing from the dll would be quicker then actually doing the hashing  yourself....

I understand that. I just don't want to be so dependant on other files (seems like an oxymoron for a vb programmer). How do the games do it? is it a function built into the program, or is there a dll you can use like storm's MPQ functions?

Check out the source code of bnetauth.dll. It has the functions you are looking for. You should have atleast a basic knowledge of C/++ before trying to understand it.

well i highly doubt you'll be able to do the NLS functions in VB, but if you do manage that, and everything else, there is still the problem of CheckRevision() taking ~5 seconds in VB (and ~20 seconds for war3)

[RealityRipple]

hmm... so in short it's really not worth it. I guess I'll stick to bncsutil for decoding and NLS. Thanks anyway, guys.

imho you should use all functions BNCSUtil has to offer, considering the fact that C++ code will execute faster than VB code no matter what.

unless it was really really poorly coded c++ code. ;\

I'm using Lord[nK]'s BNLib.dll to use the actual MPQ files to run checkrevision. Everything else is BNCSUtil based.

Where is BNLib.dll located? Upload it  ?

Thanks for the link, I kinda over looked that, I guess. Can't wait to try it.

If you want just the dll, it's in HDX's downloads folder on his site. I also made a nice icon for the dll if you want to put it somewhere on your programs. http://realityripple.com/Uploads/BNLib.ico
