A simple command-line tool that checks if your passwords have been compromised using the Have I Been Pwned API. This tool helps users ensure their passwords are secure and encourages them to change compromised passwords.
- Check multiple passwords at once.
- Clear console output for better readability.
- Color-coded output indicating password security status.
- Python 3.x installed on your machine. You can download it from Python
requestslibrarycoloramalibrary
You can install the required libraries using pip:
pip3 install requests colorama pip3 install colorama
- Clone this repository:
git clone https://github.com/cainepavl/password_checker.git
cd password_checker
- Run the program with your passwords as command-line arguments:
python3 password_checker.py password1 password2 password3
... replace password1, password2, and password3 with the passwords you want to check.
For a SAFE password the output will be GREEN:
password123 was found 5 times...</span>
You should change it!</span>
For a COMPROMISED password the output will be RED:
mySecurePassword is good to go!
-
Password Hashing: The program takes each password, hashes it using SHA-1, and sends the first 5 characters of the hash to the Have I Been Pwned API.
-
API Response: The API returns a list of hashes that start with those 5 characters, allowing the program to check how many times the full password hash appears in the database.
-
Output: The program displays whether each password is compromised or secure, with color-coded messages for better visibility.
