How to Crack Software | Full Guide With Tools Used To Repair Cracks

There are many new programs every day. But the bad news is most of them are shareware which means you have to pay for the full version. In most cases, the software developer sends you an unlock code by email when you sign up. However, there are “crackers” which modify the software so that you do not have to pay for the full version. Let’s learn how to crack software.

If you want to crack a program yourself, first run the program you want to restore and try to activate it with a random key to see if you need a valid software key to continue. This way, you can find the key.

  • Then install the debuggers: ida, ollydbg, etc.
  • Then run ollydbg.
  • Also, open the application you want to ignore using ollydbg.
  • Press the play button and run the program in the debugger.
  • Right-click in the CPU window and select Search -> All connected calls.
  • It will search for the most interesting DLL files. Then, in the dialogue box that appears when you try to enter a software key, you will see “GETDLLGITEMTEXT.”
  • By calling this function in the debugger, you can specifically check the registry.

How To Crack Software

Companies and individuals use software to carry out a task. But how does it work? What are the underlying principles that create software, which enables computers to do what they do? This article will discuss these ideas, as well as how to go about cracking software yourself.

Software is made up of instructions for a computer – step-by-step lists of things that have to be done to accomplish certain goals. These instructions are written in code, so people who write software are often called coders or developers.

For example, if the aim is for the user to undertake basic arithmetic operations on two numbers taken from a list stored on their phone taken from contacts etc. Then firstly, there would need to be an application on their phone that can handle numbers and strings, then a form to enter the numbers, a button to click to execute the operation requested. Next is a list of operations they can choose from (such as + – * /) and, finally, an output box where the results are shown.

These instructions also have to be written in code for them to be read by machines. This is done by using programming languages such as JAVA, Swift, etc. An analogy could be made with English: if you wanted someone who understood English but didn’t speak it to understand your message, then you would need to express it in a way that they could comprehend e.g.

Do you know!

“The big red dog chased my cat.” If another person who was a native English speaker said the same thing, it would be one sentence. The meaning of each word is fairly obvious, and there are no irregularities in how the words or sentence structure are formed. The receiver would also have a large dictionary at their disposal from which they could look up certain words if need be, e.g. “chased” to find out that it means “to follow quickly after somebody/something”.

In programming terms, this would be equivalent to giving the coder a reference manual for all possible commands – something which obviously wouldn’t work as they couldn’t understand anything else that didn’t appear in here either!

The first step when cracking software is to download an unprotected copy (if you can find one) off the internet. To do this, you will need to search for cracked software. This is very easy as there are countless websites online that provide the service of uploading/downloading software for free – an example being which offers thousands of software downloads links.

Once downloaded, run it and see if you can find any security flaws, e.g. a command prompt that opens asking for a password or something similar.

If the application doesn’t appear to have any such points of vulnerability, just look around some more within the interface itself. There may be ways to access certain hidden menus etc., so look carefully! But remember: everything has its limits, and eventually, cracks always show themselves, so don’t expect every program to be crackable.

When you do uncover a way to create your free versions of the software, remember that it might only be the trial version, so this means that after so many days/weeks/months, etc., there is usually some fine print saying, “you must buy full version”. So it would be helpful if you could find information about what system it uses to keep track of how long you have had access for.

The thing is;

This is commonly referred to as an activation code and is usually kept on record by the developers for legal reasons. This part might require some more digging around, but think logically: if it has serial numbers required by the program itself, they need to be somewhere on your computer or within the program files.

You will just have to try cracking that specific program using many different codes until you get it – time-consuming but not impossible! Once the application has been activated, feel free to go ahead and use it as normal.

It may be helpful, though, to leave a “back door” of sorts behind if you want to make more changes or need a reminder of your original password/codes, etc., so remember to leave a command prompt open for future reference! Search online for how to do this if unsure. Remember: all software does have its limits, and once reached, it becomes useless, regardless of what some might try and tell you!

However, don’t expect your lifelong cracking career to start from this point onwards. It is easy enough on most websites or software that has no protection. Still, if the challenge lies in cracking originals (offering full functionality and all features), then you will need to look elsewhere.

You can also use SENDDLGITEM.

  • To find out which method completes the startup cycle, right-click on the DLL call and set a breakpoint on each call.
  • Then restart the application and enter the key of the selected software.
  • The DLL book has been found if the debugger stops (the program stops) when this key is entered.
  • In the editor window, press F8 again, and the next step is “EAX TEST.”
  • EAX is a return value, which means that a test is performed here.
  • After the test, you can see that EAX is looking for a non-zero number. This means that if you replace it with a non-zero number, it will work.
  • Right-click on EAX and change the six-digit value from 0 to 1.
  • Run the program again to activate it.

What are the Most Common Tools used to Repair Cracks?

How To Crack Software


It’s a modern debugger with a nice user interface and a worthy successor to OllyDbg. It supports both x64 and x86 architectures and has many useful extensions.

Of course, it has the disadvantage that it contains many annoying bugs. However, it is actively developed and supported. Moreover, since the debugger runs in user mode, it is naturally vulnerable to various debugging techniques. However, this is partially offset by the availability of a large number of built-in tuners.

The x64dbg has a built-in decompressor and import rebuilder (both x64 and x86), supports code diagramming and reading, writing, editing, and adding breakpoints.


WinDbg is one of the best kernel and driver debuggers. It is supported by Microsoft and is part of the Windows Driver Suite (WDK).

It is the latest and most powerful kernel aligner. Its interface is not as user-friendly as x64dbg, but you don’t have many other options since other debuggers do not support kernel code.

“WinDbg supports remote debugging, so you can read debug files directly from a Microsoft server. VirtualDJ-booster is used to speed up WinDbg’s configuration to do kernel debugging on virtual machines.

“WinDbg is certainly not for beginners, but there’s no reason not to use it as you gain experience in reverse engineering and experiment with its various interesting features.

With WinDbg, you can visualize various system structures and easily extract NTAPI functions. Of course, it can also be used for debugging “normal” applications. but I choose this powerful weapon only when I need it!


Without a static code analysis tool, it would be impossible to implement. The current range of disassemblers is not as good as that of debuggers.

IDA disassembler

IDA has a paid professional version and a free version for beginners. Unfortunately, the free version is for x86 only and does not support extensions. The professional version extends the functionality to support many processor architectures and extensions.

IDA has a built-in debugger with very simple functions, but the unique user interface takes some getting used to. IDA can be extended with the Hex-Rays extension, a decompiler program for C code applications.

This is very useful because it significantly improves the speed of the analysis of your application.

Overall, IDA is a very powerful and mature tool that has been in development for a long time. Unfortunately, the price of the professional version is between $500 and $1000 (depending on the type of license), so it is not affordable for everyone.

So you should be open to other alternatives.


“Radar2 was originally developed as a simple hex code processor, but it has now evolved into a complete system for debugging and disassembling all types of code, including firmware, viruses, and crackers.

“Radar” is a console toolkit consisting of a debugger, disassembler, decompiler, hex compiler, custom compiler, and binary compiler. In addition, the system adds a graphical user interface, “Cutter,” which greatly improves the appearance of the Radar structure.

It is compatible with various processors and platforms and can compete with IDA Pro products. Another major advantage of Radar is that it is open-source, free, and community-based.

Other features

Decryption requires a variety of tools, including packet scanners, network monitors, and hexadecimal decoders. The most important ones are in more detail.

It is an excellent packet scanner with many useful features. For example, it allows you to see the entropy of a file segment, which makes it easy to check the encoding visually.

DiE makes it easy to access import tables, add extensions and scripts, configure signature analysis methods, display file headers, etc. Full support for PE and PE+.

The only problem with this solution is the slow update cycle, but it has not been abandoned.


Different coils, different protection sensors.

The user interface is not traditional and will not please everyone. But, on the other hand, it has frequent updates and offers many interesting features and practical opening tips.

We definitely can recommend it to beginners.

“ExeInfoPE has several automatic decryption tools and shows which tool you need to crack a system that has security stages.

Of course, there are also many standard features, such as displaying headers and file names, a six-digit search, and even smaller built-in tools, such as process termination ExeInfoPE also supports extensions.


Sometimes you need to access a disk, memory, or application in binary mode. The application is free, frequently updated, supports the most common formats, is searchable, and has a user-friendly interface.

Other good features include the ability to delete files (” Zerofill “) remotely. There is also a portable version that you can save to a USB stick.


This 6-core processor has a long history, but developers continue to support it.

There are free and paid versions (the latter costs 20 USD without updates and 200 USD with lifetime updates).

The Norton Commander-like interface can be awkward for new users, but it is easy to handle.

What’s particularly interesting is that HIEW is keyboard-only, and keyboard shortcuts can control all functions.
