Features

• Mode 1: Password Simulation: Analyze and simulate cracking numeric passwords using brute-force methods.
• Mode 2: PDF Cracking: Perform real brute-force attacks on encrypted PDF files with an intuitive file selection dialog.
• Live progress tracking with ANSI color output.
• Support for parallel processing in auto mode for improved performance.
• Option to save decrypted PDFs after successful cracking.

Sample Output

Mode 1:
HASH: b634e7fc... TRY: 017607000 H/s: 841k TIME:20.93s [░░░░░░░░░░░  1.76%]
✓ PASSWORD CRACKED! (12.38% keyspace, 15.33s)

Mode 2:
PDF: encrypted.pdf TRY: 012345 H/s: 95 TIME: 2.5s [████████░░░░ 50.00%]
✓ PDF PASSWORD CRACKED! (Password: 123456)

Installation

1. Ensure you have Python 3.x installed on your system.
2. Clone the repository or download the source code.
3. Install the required dependencies:

pip install pikepdf

Usage

Run the script from the command line:

python ciperX.py

1. Choose the desired mode:
   • Mode 1: Password simulation
   • Mode 2: PDF cracking
2. For simulation mode: Enter a numeric PIN (1-10 digits) to simulate cracking.
3. For PDF mode: Provide the path to the encrypted PDF file. Select whether you know the password length for optimized cracking. The auto mode utilizes parallel processing for faster results.
4. After successful PDF cracking, you have the option to save the decrypted PDF.

Requirements

• Python 3.x
• pikepdf library for PDF manipulation (pip install pikepdf)

Technology

• Pure Python implementation for password simulation demonstrations.
• Utilizes pikepdf for handling real PDF encryption and decryption.
• Features ANSI color support for enhanced terminal output.
• Includes live progress bars and updates during cracking processes.
• User-friendly file selection dialogs for PDF input.
