    For anyone wanting to start KeyGenning here is another very simple KeyGenMe to learn the basics on. Some found keygenme#1 too hard when it came to writing the MASM code - so this keygenme is even simpler . Ziggy's KeyGenMe#0 - very easy - about as simple as they get. The registration algorithm is simple and has been ripped from a real app - CTP Software Find It! 1.09. As far as I could make it, the registration algo code is the same as the real app. If you write your own keygen, you can use it on the real app. By following this tutorial, you will easily recognise the algo code in the real app. This KeyGenMe is a learning opportunity and the the aim is to provide help …

    CrackMe · Started by Guest Tundra,

    Hi, this crackme is from the SnD site, and I'm wondering how I'm supposed to input the serial into the program. When you run the program from Windows, a message box immediately pops up saying "The password is incorrect." When you press the OK button, the program exits. So I assume this is supposed to take input from the command line, but that doesn't seem to work either. Could anyone help me out? Thanks
