PassBreachFinder

PassBreachFinder is a simple Python script that checks if a password has been compromised using the Have I Been Pwned service. The script automates the process of querying the website by using Selenium and retrieving the results for the given password.

Features

• Check if a password has been compromised: Pass a password via the command line, and the script will tell you if it's been part of any known data breaches.
• Headless Browser: Uses a headless Firefox browser for automated web scraping without requiring a GUI.

Prerequisites

To use this script, you’ll need the following:

• Python 3.x
• Selenium
• Geckodriver (for Firefox)
• Firefox Web Browser

Install Required Packages

You can install the necessary Python libraries by running:

pip install -r requirements.txt

Additionally, make sure that Geckodriver is installed on your system and accessible via the PATH.

Download Geckodriver (for Firefox):

1. Download the Geckodriver that matches your system’s architecture.
2. Extract it and add the path to the Geckodriver executable in your system's environment variables or specify the path directly in the script.

Usage

1. Clone or download the script.
2. Open a terminal window in the directory where the script is located.
3. Run the script by providing a password using the -p option:

python app.py -p "your_password_here"

Example:

python app.py -p "password123"

If the password has been compromised, you will see a message like:

password123 This password has been pwned 5 times.

If the password is safe, you will see:

safe

How It Works

1. Command-Line Argument: The script accepts a password as an argument via the command line (-p).
2. Headless Browser: It uses Selenium with a headless Firefox browser to interact with the Have I Been Pwned Passwords page.
3. Password Checking: It enters the provided password into the search form on the page and submits it. After waiting for the results, it checks if the password has been pwned.
4. Results: The script will display whether the password is safe or has been exposed in a data breach.

Troubleshooting

• Geckodriver Not Found: If you're getting an error regarding Geckodriver, ensure it’s installed and properly referenced in the script or the environment variables.
• Headless Mode: If you'd like to see the browser in action (not headless), remove or comment out the line options.add_argument("--headless").
