This is where the authentication key is checked, if anyone can do anything with this.

Code: [Select]

; int __stdcall sub_4447E0(HINSTANCE hInstance, HWND hWndParent, int, char, int, int)
sub_4447E0 proc near

hInstance= dword ptr  4
hWndParent= dword ptr  8
arg_8= dword ptr  0Ch
arg_C= byte ptr  10h
arg_10= dword ptr  14h
arg_14= dword ptr  18h

mov     eax, [esp+arg_8]
mov     edx, [esp+arg_10]
push    ebx
mov     [ecx], eax
mov     al, [esp+4+arg_C]
xor     ebx, ebx
push    ebx             ; dwInitParam
mov     [ecx+26h], al
mov     eax, [esp+8+hWndParent]
push    offset sub_4440A0 ; lpDialogFunc
mov     [ecx+4], edx
mov     edx, [esp+0Ch+arg_14]
push    eax             ; hWndParent
mov     [ecx+24h], bl
mov     [ecx+25h], bl
mov     [ecx+28h], edx
mov     ecx, [esp+10h+hInstance]
push    87h             ; lpTemplateName
push    ecx             ; hInstance
call    ds:DialogBoxParamW
cmp     eax, 1
mov     al, 1
jz      short loc_444828


There is nothing to do here, if the authentication code is a valid format then it moves on and tries to decrypt the files using it. There is only 1 valid code that will decrypt the files, it is only stored on the blizzard servers.

I want to play this game so badly.It is horrible thinking that Vernam is now playing the game and wont share his crack.
Im sorry that i dont understood about the protection next time will read  carefully.

don't worry, he ain't playing it. Why do you think he won't release anything up to the release date? easy: he lacks the authentification key which blizzard sends to your computer once you try to install the game. (The authentification key is needed for the install, you can't bypass the protection without it).

The MPQE decryption is vital if you want to install the game, without it those files are nothing but incoherent data which has no direct relation to the real game data.

Now since we don't have the key, we must deduce it. Think of it like when you try to open a locker and you don't have the correct combination, you just go trying all possible combinations.

The same happens in this case, just that we have 2^256 combinations, the big problem is that a computer may at best try 1000000 combinations per second (I may be exagerating here, it may be way way less; haven't read Salsa20's algorithm yet) in other words in our best case we will be able to deduce 1 million combinations per second. Yet, we have 2^256 combinations, that means it takes 2^256/1000000 seconds to try all combinations, and that would be aprox 2^236 seconds which would be 2^224 hours pretty much. As you see, that's a lot of time, we may actually die before the computer could deduce the god damm key.

If you don't believe me and still think that everything is so easilly cracked, look for a .rar unlocking tool, you'll notice that all it will do is try all the possible passwords until it finds one.
