+# Password Strength Checker
+
+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.
+
+## Features:
+- **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.
+
+## Installation:
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/your-username/password-strength-checker.git
+   ```
+
+2. Navigate into the project directory:
+   ```bash
+   cd password-strength-checker
+   ```
+
+3. Create a virtual environment (optional, but recommended):
+   ```bash
+   python -m venv venv
+   ```
+
+4. Activate the virtual environment:
+   - On **Windows**:
+     ```bash
+     venv\Scripts\activate
+     ```
+   - On **macOS/Linux**:
+     ```bash
+     source venv/bin/activate
+     ```
+
+5. Install the required dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+## Usage:
+
+To run the script, simply execute:
+
+```bash
+python password_strength_checker.py
+```
+
+You 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.
+
+## Dependencies:
+- `requests` - for making HTTP requests to the "Have I Been Pwned" API.
+- `password-strength` - for evaluating password complexity and strength.
+- `matplotlib` - for generating graphical reports.
+- `colorama` - for adding color to the terminal output.
