rules:
1.keygen

2.and if you can make atut

 

have fun:D

 

btw:

1.i set the buffers small so if you try to enter more chars than it can get the crackme will be crashed(find out how max you can enter)

2.there no bad message(so if you enter bad serial it will close it self)

CrackMe.rar

name: ChOoKi

code: aHmMiG

 

name: DMichael

code: dkGAH?CL

 

A two line source (tut):

for i := 1 to length(name) do
  ser := ser + chr((ord(name) xor $21) -1);

 

Notes: Max to enter is 11, also some name characters might result in unprintables in serial, so stay away from them

Thanks for the challenge, very simple but fun

dont really now what the problem is if you could post some info (just make ollydbg as JIT and send me picture of crash)

@GIV you could also try to click the label "Click here" to get some more info's about where the crash happened. Offsets and modules etc.
