DLL files are dynamic link libraries that contain code and data that can be used by multiple programs. By modifying the DLL files of Lighten PDF Converter OCR, you can change the way the software behaves and bypass its copy protection. To do this, you will need a disassembler, a debugger, and a hex editor. A disassembler can convert the binary code in the DLL files into assembly language, which is easier to read and understand. A debugger can help you find and modify the code that controls the license verification and the trial period. A hex editor can help you edit the raw bytes in the DLL files.
One of the tools that you can use for this purpose is IDA Pro, which is a powerful disassembler and debugger. You can download a free version of IDA Pro from [here]. Another tool that you can use is OllyDBG, which is a free debugger that can also open DLL files. You can download OllyDBG from [here]. For hex editing, you can use any hex editor of your choice, such as HxD, which you can download from [here].
The basic steps to hack Lighten PDF Converter OCR are as follows:
Open the software and find out which DLL files it loads. You can use a tool like Process Explorer or Process Hacker to do this. Alternatively, you can open the software folder and look for DLL files with names related to the software functions.
Open one of the DLL files in IDA Pro or OllyDBG and look for the code that checks the license or the trial period. You can use the search function or the strings window to find keywords like "license", "trial", "expire", "register", etc.
Set a breakpoint on the code that checks the license or the trial period and run the software. When the breakpoint is hit, examine the registers and the stack to see how the software determines whether it is registered or not.
Modify the code that checks the license or the trial period to always return a positive result. You can do this by changing some instructions or bytes in the code. For example, you can change a conditional jump to an unconditional jump, or change a comparison to a nop (no operation).
Save the modified DLL file and replace the original one in the software folder. Run the software again and see if it works without asking for a license or showing a trial expiration message.
Repeat steps 2-5 for other DLL files that may contain license or trial checks.
By following these steps, you should be able to hack Lighten PDF Converter OCR 6.1.1 and use it for free. However, keep in mind that hacking software is illegal and unethical, and may cause damage to your system or data. You should only do this for educational purposes and not for personal gain. In this article, I will show you some examples of how to hack Lighten PDF Converter OCR 6.1.1 using IDA Pro and OllyDBG. These examples are for demonstration purposes only and do not cover all the possible scenarios and DLL files that may need to be modified. You should use your own judgment and skills to find and modify the code that suits your needs.
Example 1: Hacking LightenPDFConverterOCR.dll
One of the DLL files that is loaded by the software is LightenPDFConverterOCR.dll, which contains the main functions of the software, such as converting PDF files to different formats and performing OCR. This DLL file also contains the code that checks the license and the trial period of the software. To hack this DLL file, you can follow these steps:
Open LightenPDFConverterOCR.dll in IDA Pro and go to the strings window. Search for the string "license" and double-click on it. You will see that this string is referenced by a function named sub_1000B6C0.
Go to the function sub_1000B6C0 and examine its code. You will see that this function calls another function named sub_1000B4E0, which is responsible for verifying the license key entered by the user.
Go to the function sub_1000B4E0 and examine its code. You will see that this function performs some calculations and comparisons on the license key and returns a value in the EAX register. If the value is 1, it means that the license key is valid; otherwise, it means that the license key is invalid.
Set a breakpoint on the instruction that returns from the function sub_1000B4E0 (ret 8) and run the software. When you are prompted to enter a license key, enter any random string and click OK. The breakpoint will be hit and you will see the value of EAX in IDA Pro.
Change the value of EAX to 1 using IDA Pro's modify window or by typing "mov eax, 1" in IDA Pro's command line. Resume the execution of the software and you will see that your license key is accepted.
To make this change permanent, you need to edit the bytes in the DLL file using a hex editor. Go back to IDA Pro and note down the address of the instruction that returns from the function sub_1000B4E0 (ret 8). In this case, it is 1000B5F9.
Open LightenPDFConverterOCR.dll in a hex editor and go to the offset corresponding to the address 1000B5F9. You will see two bytes: C2 08. These bytes represent the instruction ret 8 in hexadecimal.
Change these two bytes to B8 01 00 00 90, which represent the instructions mov eax, 1; nop in hexadecimal. Save the modified DLL file and replace the original one in the software folder.
Run the software again and enter any random string as a license key. You will see that your license key is accepted and you can use all the features of the software without limitations.
Example 2: Hacking LightenPDFConverterOCRUI.dll
Another DLL file that is loaded by the software is LightenPDFConverterOCRUI.dll, which contains the user interface elements of the software, such as menus, buttons, dialogs, etc. This DLL file also contains some code that checks whether the software is in trial mode or not. To hack this DLL file, you can follow these steps:
Open LightenPDFConverterOCRUI.dll in OllyDBG and go to View > Executable modules. Select LightenPDFConverterOCRUI.dll from the list and click on View names.
In the names window, search for "trial" and double-click on it. You will see that this name is associated with a function named TrialCheck.
Go to the function TrialCheck and examine its code. You will see that this function calls another function named GetTrialDaysLeft, which returns a value in EAX register indicating how many days are left for the trial period.
Set a breakpoint on the instruction that calls GetTrialDaysLeft (call GetTrialDaysLeft) and run the software. When you open a PDF file for conversion, you will see a message saying "You are using trial version" at the bottom of the window. The breakpoint will be hit and you will see the value of EAX in OllyDBG.
Change the value of EAX to -1 using OllyDBG's modify window or by typing "mov eax, -1" in OllyDBG's command line. Resume the execution of the software and you will see that the message saying "You are using trial version" is gone.
To make this change permanent, you need to edit the bytes in the DLL file using a hex editor. Go back to OllyDBG and note down the address of the instruction that calls GetTrialDaysLeft (call GetTrialDaysLeft). In this case, it is 1000A9C4.
Open LightenPDFConverterOCRUI.dll in a hex editor and go to the offset corresponding to the address 1000A9C4. You will see five bytes: E8 17 00 00 00. These bytes represent the instruction call GetTrialDaysLeft in hexadecimal.
Change these five bytes to B8 FF FF FF FF, which represent the instruction mov eax, -1 in hexadecimal. Save the modified DLL file and replace the original one in the software folder.
Run the software again and open a PDF file for conversion. You will see that there is no message saying "You are using trial version" and you can use the software without any time limit.
These are just two examples of how to hack Lighten PDF Converter OCR 6.1.1 using IDA Pro and OllyDBG. There may be other DLL files and code segments that need to be modified to fully hack this software. You can use the same tools and techniques to find and modify them. However, remember that hacking software is illegal and unethical, and you should only do it for educational purposes and not for personal gain. Example 3: Hacking LightenPDFConverterOCRCommon.dll
The third DLL file that is loaded by the software is LightenPDFConverterOCRCommon.dll, which contains some common functions and resources that are used by the software, such as icons, images, fonts, etc. This DLL file also contains some code that displays a watermark on the converted files if the software is not registered. To hack this DLL file, you can follow these steps:
Open LightenPDFConverterOCRCommon.dll in IDA Pro and go to the strings window. Search for the string "watermark" and double-click on it. You will see that this string is referenced by a function named sub_1000F9E0.
Go to the function sub_1000F9E0 and examine its code. You will see that this function calls another function named sub_1000F8D0, which is responsible for drawing the watermark on the converted files.
Go to the function sub_1000F8D0 and examine its code. You will s
