Ok, so there is a zip-file with a working keygen. I included the file because I didn't remember exactly how the algorithm worked when I was submiting it to this site, so it was basicly just to show the admin that the crackme works.

Anyway if you manage to crack my crackme, you may request the password =)

Happy Cracking!

Please send a link to working keygen. It has been removed from .zip you send.

Ok, so I've uploaded a working keyGen.
You can find it here:
hxxp://files.filefront.com/VB+Crackme2+by+Mjinhew+KENzip/;8173618;;/fileinfo.html

It's password protected so you'll have to send me at least 1 working serial to your System ID + the hidden char.
If you don't manage to crack the app, but still want to see the keyGen. Include that in your message.

If you take 5 mins of your time, to study the algo, you'll know what I mean :)

And THE VERY BEST is if you can make the keygen in a non framework based environment PLUS a tutorial. :)

But hey, thankes for commenting!
Best regards, Mjinhew

Nice tutorial halsten, the problem is that your keygen can dispay 100++ invalid serials. If you study my crackme a bit you should see that you can make a keygen wich generates only 10 serials, where the correct serial will be located.

You may leave your comment, thoughts and discuss this crackme with other reversers here.
