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
