Hi all,

I am trying to produce a keygen, but am a little confused by what is happening in this section...

CompString:

push ebp

mov ebp,esp

sub esp,0000000Ch

push esi

push edi

push ebx

mov [L10087B48],ebp

mov [ebp-04h],eax

mov [ebp-08h],edx

mov ecx,[fDict_RT]

cmp ecx,00000002h

jl L10032496

push edx

push eax

call SUB_L100324AC

mov [ebp-0Ch],eax

jmp L1003249F

L10032496:

call [L10081C04]

mov [ebp-0Ch],eax

L1003249F:

mov eax,[ebp-0Ch]

cmp eax,00000000h

pop ebx

pop edi

pop esi

mov esp,ebp

pop ebp

retn

Your help is appreciated

I should make my self clearer, this is part of where the software that I am trying to create a keygen for is comparing information

Without context it is very hard to give meaningful answers. Seeing the name it might compare strings.

Here's some pseudo-c that shows what it does:

int __fastcall CompString(int arg1, int arg2){
	if(fDict_RT > 2)
	   return SUB_L100324AC(arg1, arg2);
	else
	   return *L10081C04();
}

Not like that's very meaningful...

Thanks for that, its a bit hard to explain because I pretty much know nothing about programming at all except what I have gained from websites.. I have been able to edit the main exe of the program to get about 85% of all functions, however some still do not appear on the menu...So I thought I might try and work out how it is calculating the serial. I know that the main exe refers to this section to compare the serial entered, the problem I am having is understanding what it is comparing it against...bit of a conungram...I am able to send u a full copy of the dll if u like for some further input?? Again all help is appreciated

Thansk again Rocky
