# Password Analyzer
Password Analyzer is a modern React and FastAPI web application designed to evaluate password security using industry-standard tools and a professional interface.
It analyzes password length, entropy, and overall strength, and cross-references them with the HaveIBeenPwned database to identify compromised passwords.
---
## Features
- **Advanced Strength Estimation**: Powered by the zxcvbn library for realistic security scoring.
- **Data Breach Detection**: Uses the HaveIBeenPwned API to check if passwords have appeared in known leaks.
- **Detailed Insights**: View entropy, time-to-crack estimates, and actionable security suggestions.
- **Premium Interface**: A modern dark mode design with glassmorphism effects and fluid animations.
- **Real-time Feedback**: Instant results as you analyze your passwords.
---
## Technical Stack
- **Frontend**: React (Functional Components, Hooks)
- **Backend**: FastAPI (Python)
- **Security Logic**: zxcvbn, HaveIBeenPwned API
- **Styling**: Vanilla CSS with custom properties and backdrop filters
- **Deployment**: Docker Compose
---
## Deployment
The application is fully containerized for easy deployment.
### Prerequisites
- Docker
- Docker Compose
### Run the Application
```bash
docker-compose up --build
```
The frontend will be available at http://localhost:3000 and the backend API at http://localhost:8000.
