A Python-based tool that checks password strength in real-time, providing feedback on complexity, evaluating entropy, checking against common passwords, and verifying if the password has been exposed in data breaches using the "Have I Been Pwned" API.
- Real-Time Feedback: Provides immediate feedback on password strength as you type.
- Password Rating System: Rates the password as "Good", "Fair", or "Poor" based on entropy, breach risk, and character variety.
- Password Breach Risk: Checks if the password has been exposed in data breaches and assigns a risk score.
- Password Complexity Analysis: Evaluates the password's entropy and variety (length, characters, numbers, symbols).
- Visualization: Generates a graphical report of the password's performance in various security criteria.
- Common Password List: Uses an up-to-date list of common passwords fetched from an external source.

Clone the repository:
git clone https://github.com/your-username/password-strength-checker.git
-
Navigate into the project directory:
cd password-strength-checker -
Create a virtual environment (optional, but recommended):
python -m venv venv
-
Activate the virtual environment:
- On Windows:
venv\Scripts\activate
- On macOS/Linux:
source venv/bin/activate
- On Windows:
-
Install the required dependencies:
pip install -r requirements.txt
To run the script, simply execute:
python password_strength_checker.pyYou will be prompted to enter a password. The tool will evaluate the strength of the password and give you real-time feedback. After submitting the password, a visual report will be generated showing how it performs across various security criteria.
