-===========================-
Introduction
------------
I take no responsibility of the usage of this information.
This tutorial, is for educational knowledge ONLY.
Hi there, in this tutorial, I intend to teach you how to make a pretty
simple keygen, of a program called W3Filer 32 V1.1.3.
W3Filer is a pretty good web downloader...
I guess some of you might know the program.
I`ll assume you know:
A. How to use debugger (in this case, SoftIce).
B. How to crack, generally (finding protection routines,patching them,etc...).
C. How to use Disassembler (This knowledge can help).
D. Assembly.
E. How to code in Turbo Pascal ™.

Tools you`ll need:

A. SoftIce 3.00/01 or newer.
B. WD32Asm. (Not a must).
C. The program W3Filer V1.13 (if not provided in this package), can be found in
www.windows95.com I believe.
D. Turbo Pascal (ANY version).
Well, enough blah blah, let's go cracking...
Run W3Filer 32.
A nag screen pops, and , demands registration (Hmm, this sux ;-)) Now,
We notice this program has some kind of serial number (Mine is 873977046),
Let's keep the serial in mind, I bet we`ll meet it again while we're on
the debugger.
Well, now, let's put your name and a dummy reg code...
set a BP on GetDlgItemTextA, and, press OK.
We pop inside GetDlgItemTextA, Lets find the registration routine...
I`ll save you the work, the registration routine is this:

:00404DB2 8D95A8FAFFFF lea edx, dword ptr [ebp+FFFFFAA8]
:00404DB8 52 push edx ---> Your user name here.
:00404DB9 E80B550000 call 0040A2C9 ---> Registration routine.
:00404DBE 83C408 add esp, 00000008 ---> Dunno exactly what is it.
:00404DC1 85C0 test eax, eax ---> Boolean identifier, 0 if
:00404DC3 7D17 jge 00404DDC ---> registration failed, 1 if
OK.

Well, Let's enter the CALL 40A2C9, and see what's inside it:

รบกวนนิดนะครับ conanjung ..
คืออยากให้ช่วยแก้ เอาส่วนที่ เป็น code ไปใส่ไว้่ใน tag code นิดนึงอ่ะครับ แล้วช่วยแบ่งออกเป็นส่วนๆด้วย ... คือ นั่งอ่านแล้ว มันดูมั่วๆยัีงไงก็ไม่รู้

อ๋อ ... แล้วรบกวนใส่หัวข้อให้หน่อยครับ เพราะว่ามันเป็น Keygen ของ W3Filer 32 V1.1.3. มันเอาไปใช้กับตัวอื่นๆไม่ได้ ...
