Password Cracker

This project is a Python-based password cracker that demonstrates the effectiveness of brute-force and dictionary attacks against hashed passwords. It includes a command-line interface (CLI) as well as a graphical user interface (GUI) built with tkinter.

Features

• Supports sha224, sha256, and md5 hashing algorithms.
• Two cracking methods:
  • Brute-force Attack: Tries all possible combinations of characters.
  • Dictionary Attack: Uses a precompiled wordlist, such as rockyou.txt.
• GUI interface for easy interaction.
• Command-line interface for advanced usage.

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/password-cracker.git
   cd password-cracker

2. Create a virtual environment (optional but recommended): bash Copy code python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate

3. Install the required Python packages: bash Copy code pip install -r requirements.txt

4. Download the rockyou.txt wordlist (if you don't have it already):

Usage

Command-Line Interface

You can run the password cracker directly from the command line using main.py :
python main.py <hashed_password> --method --wordlist <path_to_wordlist>
• <hashed_password>: The hashed password you want to crack.
• : The hashing algorithm (sha224, sha256, md5).
• --method: The cracking method, either brute-force or dictionary.
• --wordlist: Path to the wordlist file (required for dictionary attack).
Example: python main.py 5f4dcc3b5aa765d61d8327deb882cf99 md5 --method dictionary --wordlist wordlists/rockyou.txt

Graphical User Interface

The project also includes a tkinter-based GUI for easier interaction. python password_cracker_gui.py

1. Enter the hashed password.
2. Select the hash algorithm.
3. Choose the attack type (brute-force or dictionary).
4. For dictionary attacks, specify the path to the wordlist.
5. Click "Crack Password" to begin.

Testing

Unit tests are provided in the tests/ directory. You can run these tests using the unittest framework.

python -m unittest discover tests
