Date:17th June 1999
Program name: DiABLOS´s CracKMe #4
Program type: W32
Program location: Here
Program filename: N/A
Program size: 266KB

Tools required:
SoftIce v3.**

Difficult level:
Easy (  X  )  Medium (   )  Hard (    )  Pro (    )
 

today is time to crack a little easy crackme and to Keygen it :)
Goto The CrackMe, an enter :
name : ACiD BuRN
Serial : 123456
For this crackme we will use hmemcpy so , in Soft ice : bpx hmemcpy
Press on the button an Soft ice Breaks. 
Press F11 Once, And Then F12 (for me i pressed 39 times F12 coz the 40th show us the error message .
Then trace the code with F10 and u will come to :
xxxx:0040189C
This call is important so enter in it : F8
trace with F10 , you will see :
Mov EAX, [EAX] <== Fake Serial : 123456
Mov EDX, [EDX] <== Good Serial: 00410043006900440020004200750052
type : "d eax" to see your fake code
type : "d edx" to see your real code
But to be sure , there is not other calcul on the code trace with F8 to enter is the next call
Now trace with F10 , you will see :
Cmp eax , edx <=== eax = 123456 and edx = 00410043006900440020004200750052
jz blablabla ... <=== jump to code cracker if eax = edx so we have just to enter the serial in edx.

Cool !! the Crackme say us good work =)) and now a cool prize for us !! a cool pic !!

Now , how to make a keygen :

For this , you only need a brain !!! heheh
Coz the serial for ACiD BuRN is : 00410043006900440020004200750052
And what is the hex ascii value of ACiD BuRN ? : 4143694420427552
so , the crackme take each ascii value of you name in hex and add it "00" before !!
That is lame easy to make a keygen now !!

VB5 source of a Keygen :

----------------------------------------------
For x = 1 To Len(Text1.Text)
code = Hex(Asc(Mid$(Text1.Text, x, 1)))
Text2.Text = Text2.Text & "00" & code
Next x
-----------------------------------------------

That 's all !! =)

i hope you have learn something with this tut , and sorry for my bad english.
