## Overview

Comprehensive password strength analysis tool that calculates entropy, simulates dictionary and brute-force attacks, scores passwords against NIST SP 800-63B guidelines, and provides actionable recommendations for improvement.

## Features

- **Entropy Calculation** — Shannon entropy with character set analysis
- **Dictionary Attack Simulation** — Tests against common password lists
- **Brute-Force Time Estimation** — Time-to-crack calculations
- **NIST Score** — Compliance scoring against NIST SP 800-63B
- **Actionable Recommendations** — Specific improvement suggestions
- **Batch Analysis** — Analyze multiple passwords at once

## Quick Start

```bash
git clone https://github.com/Raphasha27/Password-Analyzer.git
cd Password-Analyzer
pip install -r requirements.txt
python analyzer.py --password "YourPasswordHere"
```
