Have you ever wanted to learn how to self-copy-protect a program? With the right tools, you should be able to analyze the inner workings of a program and see how copy protection works. With assembly language (Assembly – a kind of low-level programming language), you can even change these programs to use without having to register or pay. If you want to do this, you need to jailbreak the software by changing the DLL file.

Learn about Assembly programming. To crack most software, you need a good understanding of assembly language. Derived from machine language, so each assembly language is specific to the type of computer you are using. Most assembly language is expressed in binary and hexadecimal.

Install the software decompiler tool (disassembler). To analyze and edit DLL files, you need various tools, including disassembler. IDA Pro is a good choice as it is both a decompiler and a debugger. Fortunately, there is a free version available at https://www.hex-rays.com/products/ida/support/download_freeware, although it is quite limited in functionality compared to the Pro version. You can also try dotPeek which is a DLL-enabled source code extraction tool that converts the assembly code of .NET files to C# code. [1] X OllyDBG Application Research Source is another option that allows you to open DLL files for free.

Start the program you want to crack with the disassembler tool. The process may vary depending on the disassembler you are using. It will show you the DLL files being loaded by the program. Use the debugger tool to check which function is being called from the DLL file. [2] X Research Source

Find the timing feature. Many programs use a timer feature to prevent copying, and when the time expires, the user will not be able to access the program. Our goal is to find and bypass the timing code.

  • If the program you are jailbreaking uses another form of protection then you need to find that feature.

Set a breakpoint for the timer. After isolating the timer feature, set SoftIce to interrupt every time it’s time. This will allow you to see the exact code that happens when the timer is called.

Change the timer code. Once you find the code for the timing feature, you can change it so that the timer never reaches a point where you can’t access the program. For example, you can make the timer uncountable to the interrupt limit, or jump to pass the counter.

    Recompile the cracked software. After retrieving the code and editing it, you need to edit the new version of the program so that the changes are updated to the DLL and other dependent files. [3] X Research Sources
