But should I swap the values returned by cdKeydecode?

No!!

But without swapping dwKey1Product and dwKey2Product they are wrong

Uhm how can I fix that? or is there another better CheckVersion() function?

Just use memcpy like someone else suggested..

I dont mean that my WriteDWord function doesn't work, I mean that dwKey1Product is 0x00000006, when the real client sends 0x06000000.

Yes.  I know that.  I never had to swap bytes before because i've always used RtlMoveMemory/memcpy.  Sorry, your WriteDWord function threw me off a lot

Mhh, I don't use memcpy, do I have to swap all the hashes too then?
EDIT: And about the second cd key value1, and the ExeInfo, anyone knows why are they different than the ones the real client sends?

Guys, my god, get on AIM or something.  There have been ~15 posts to this thread in the last half-hour; I watched an entire page get added to this thread while I ate a small cookie-dough blizzard from Dairy Queen.

Uhm I discovered something...
I made this program to see if CheckRevision() works well...

#include <windows.h>
#include <iostream>
#include <fstream>
#include <string>
#include <sys/stat.h>
#include <windows.h>
#include <process.h>
#include <commctrl.h>
#include <winreg.h>
#include <conio.h>

#include "CheckRevision.h"
#include "D2Test.h"

using namespace std;



int test1();


int main(void)
{
   test1();
   return 0;
}


int test1()
{
   int i = 0;
   DWORD RealChecksum = 0x901CF41B;
   DWORD CRVersion = 0;
   DWORD CRChecksum = 0;
   char ExeInfo[5000];
   memset(ExeInfo, 0, 5000);
   BOOL bCheckRevision = 0;
   bCheckRevision =
      CheckRevision("C:\\Archivos de programa\\Diablo II\\Game.exe",
         "C:\\Archivos de programa\\Diablo II\\BnClient.dll",
         "C:\\Archivos de programa\\Diablo II\\D2Client.dll",
         "A=256586614 B=432471822 C=762285261 4 A=A^S B=B+C C=C-A A=A^B",
         &CRVersion, &CRChecksum,
         ExeInfo, "IX86ver0.mpq");
   if(!bCheckRevision)
   {
      cout << "CheckRevision() failed" << endl;
      exit(0);
   }

   cout << "CRChecksum: " << hex << htonl(CRChecksum) << endl;
   cout << "CRVersion: " << hex << htonl(CRVersion) << endl;
   cout << ExeInfo << endl;
   return 0;
}


I logged a real connection between D2 and BNet, I got ValueString and MPQ Filename, and I called CheckRevision() with these to see if the exe hash it returns is the same than battle.net's...
It wasn't the same. Then, I ran the program again to see if it was random or something. It isn't random. Then, I changed D2Client.dll for storm.dll, the checksum changed... (but still not Battle.net's). And then I swapped D2Client.dll with BNetClient.dll and the checksum changed too... so does anyone know the exact files and the exact order of them to pass to CheckRevision()?



EDIT:
Confirmed:
-The files needed are: Game.exe, Bnclient.dll, and D2client.dll
-They go in that order.
dwVersion and dwExeHash are given in Big Endian, so they must be converted to Little Endian to put in the packet.
-ExeInfo string is still different, but as dwVersion and dwExeHash work, I suposse I could safely just copy the string D2 sends into ExeInfo.


EDIT:
I go to sleep, it's v late here.

I did the changes to CheckVersion that I wrote in the post above, and the 0x51 received packet has changed! now it is the "invalid CdKey" packet.

EDIT: uhm now it also IP bans me, is that normal?

CheckVersion() seems to work fine now, I managed to generate the same ExeHash than d2 client changing the order of the files (and using fixed values I got from the d2 packet log)

Is this code right? I want it to find out which is the cd key that is invalid, but in the second switch() it goes to the default.


LTBNSixthPacket()
{
   int n = 0;
   BEFORE_RECV;
   n = RecvPacket(crSixthPacket.packet, 50);
   if(n == -1) error(9, "RecvPacket");
   else cout << "Packet 6 Recv. Bytes: " << n << endl;
   
   memset(r_SID_AUTH_CHECK.AdditionalInformation, 0,
      sizeof(r_SID_AUTH_CHECK.AdditionalInformation));
   crSixthPacket.ReadByte(&r_SID_AUTH_CHECK.IntegrityCheck);
   crSixthPacket.ReadByte(&r_SID_AUTH_CHECK.PacketID);
   crSixthPacket.ReadWord(0, &r_SID_AUTH_CHECK.PacketLen);
   // Im converting this dword to big endian before parsing it.
   crSixthPacket.ReadWord(0, &r_SID_AUTH_CHECK.Result1);
   crSixthPacket.ReadWord(0, &r_SID_AUTH_CHECK.Result2);
   crSixthPacket.ReadString(r_SID_AUTH_CHECK.AdditionalInformation);

   cout << endl;
   switch(r_SID_AUTH_CHECK.Result1)
   {
   case 0x000: cout << "Passed Challenge" << endl; break;
   case 0x100: cout << "Old Game Version" << endl; break;
   case 0x101: cout << "Invalid Version" << endl; break;

   case 0x200: cout << "Invalid CDKey" << endl; break;
   case 0x201: cout << "CDKey in use" << endl; break;
   case 0x202: cout << "Banned CDKey" << endl; break;
   case 0x203: cout << "Wrong Product" << endl; break;
   default: cout << "Undefined" << endl;
   }

   switch(r_SID_AUTH_CHECK.Result2)
   {
   case 0x200: cout << "Invalid CDKey2" << endl; break;
   case 0x201: cout << "CDKey in use2" << endl; break;
   case 0x202: cout << "Banned CDKey2" << endl; break;
   case 0x203: cout << "Wrong Product2" << endl; break;
   default: cout << "Undefined" << endl;
   }


   cout << "ADDITIONAL INFORMATION: " <<
      r_SID_AUTH_CHECK.AdditionalInformation << endl;

   crSixthPacket.dbgShowPacket();

   return n;
}


I have fixed the CDKey2 Value1 error , but battle.net still sends me the "Invalid CD-Key" packet and it still ip bans me. (And it ip bans me for a lot of time)

The new compare log: the 2 first logs are from real d2 client, the last log is from my prog. They seem to be identical... (Except the hashes and the client token of course)...
