📚 How It Works

The pdf_cracker.py script is designed to efficiently crack the password of encrypted PDF files by leveraging parallel processing. Here's a breakdown of its key components and functionality:

1. 🔐 Password Decryption Attempt:

   • The script attempts to decrypt the PDF file using a list of passwords provided in the specified password list file.

2. ⚡ Parallel Processing:

   • To expedite the cracking process, the script utilizes multiprocessing to parallelize password attempts. Each chunk of passwords is processed concurrently, making the most out of the available CPU cores.

3. 🔄 Multithreading:

   • Within each process, multithreading is employed to further optimize performance. This allows multiple password attempts to be made simultaneously within a process.

4. 🍱 Chunked Passwords:

   • Passwords are divided into chunks based on the specified chunk size. This allows for efficient distribution of password attempts across multiple processes.

5. ⚠️ Error Handling:

   • The script incorporates robust error handling to gracefully manage common file-related errors. Any exceptions encountered during the decryption attempts are logged for further analysis.

6. 📝 Logging:

   • Detailed logs are generated to record important events during the password cracking process. This includes information about successful password attempts or encountered errors.

7. ⚙️ Customizable Options:

   • Users have the flexibility to customize the chunk size, number of parallel processes, and number of threads per process through command-line arguments. This ensures adaptability to different hardware configurations.

8. 🚪 Exit Upon Success:

   • As soon as the correct password is found, the script exits, and the correct password is displayed. This minimizes unnecessary processing once the goal is achieved.

9. 🎓 Educational Purpose Emphasis:

   • The script is developed strictly for educational purposes and is intended to showcase the principles of parallel processing in the context of password cracking. Users are reminded to use the script responsibly and adhere to ethical and legal standards.

By understanding these key components, users can gain insights into the inner workings of the script and appreciate the efficiency achieved through parallel processing for password cracking.
