Hi javelin,
welcome back

someone is working on this project?
the characteristic of this crackme suggests two methods for those who wishes to try:
1. write a keygen ripping code from the crackme
2. inject some code to turn the crackme in a keygenerator

both tasks are not too hard but the problem is that is a console type crackme. at first, i feared about console proggie, don't know why...but there is nothing different from other programs!

The 'Thank you for registering' and 'Invalid Serial' messages will lead you on the routine protection...

regards,
ZaiRoN

Hi javelin
I started working on this project because this would be nice for me to learn write keygenerators.

I hope I can produce working keygen for this

I must stress that this will be my first actual keygenerator.. so don't expect too much from me ;-)

Hi,
I started to analyze this program and I found that it's input buffer is located in stack (perhaps this is C code, I am not 100% sure)
and, I've renamed 2 subs to 'StdIn' and 'StdOut', so the code will be more readable.
and THEN after the program gets name and code, it initializes 10 byte size variables in the stack, given values from 1 to 10.

Just a quick look at the code, more will follow..and please notice me if any of this is incorrect

just to correct my own mistakes ^^
the program initializes 10 WORDs in the stack,first variable with value 1, second with 2 and so on till the 10:th variable...

cheers
