Today in this part of the course we will reverse a program to recover passwords in RAR files.

The program is in .NET therefore we will not have to see assembly language, it will be much easier. When we open the program we see a tab that indicates if we want to register the program we click, and now we should be able to see a dialog box to introduce the license. 

Main interface

We introduce random characters and in the control structure it will be directed towards a false return value. Simply by modifying in memory false as true we would already have the program registered!. 

Activation function

And ready we would have the program registered for life. 

Registered software
