Here is the gist of what these features do. The options here are just like those found in ollydbg 1.10 with a few additional features. The configuration in the screenshot above is what I typically recommend and use for simple debugging. Here is a screenshot of the cracking video in. Thanks go out to Spiffomatic64 for this video. I would recommend that users download the video pack and the crackme all neatly provided in the link below and try the entire process themselves. This video is a highly recommended watch for budding reverse engineers!

Once the code in these routines have been understood, he proceeds to patch the binary to convert the crackme into a keygen. He first verifies using Peid that the program has not been compressed or packed and then loads this program into Ollydbg, disassembles it and then proceeds to find the place in the code responsible for the annoying alert message shown in the beginning and then finally the place responsible for the key validation checks. He then uses a simple crackme prolixe_keygenme1.zip to show how software crackers work their way through a binary.

Spiffomatic64 starts with a basic introduction to the tools of the trade - Ollydbg and Peid. In this awesome video created by Spiffomatic64, we learn about the basics of software cracking. This allows users to generate arbitrary valid keys / serials for the program.

Alternately, he can also reverse engineer the key / serial comparison routines and write a keygen for the program. He then proceeds to alter the behavior of the program by finding and changing (patching) the routines responsible for the security mechanisms, in order to allow full unlimited access to the program. A Cracker works his way through a program by disassembling it and understanding the security protections built into it. Generally software cracks are distributed in the form of patches to the original software or keygen programs which generate arbitrary key / serial combinations. Software Cracking is the art of breaking security protections in a software.
