⚙️ System Architecture

🔄 Working Flow

1. User enters or generates a password
2. Input is securely masked and processed locally
3. Analyzer evaluates:
   • Length
   • Uppercase & Lowercase
   • Numbers & Symbols
   • Entropy score
4. Strength classification is computed
5. Crack time is estimated using entropy model
6. UI updates in real-time with:
   • Strength meter
   • Entropy score
   • Requirements checklist
   • Security intelligence feedback
