   • Press F5 to start debugging

🚀 Usage Guide

1. Set desired password length using slider
2. Click "Generate" to create new password
3. View password strength indicator:
   • 🔴 Weak (below 50 bits entropy)
   • 🟠 Medium (50-80 bits entropy)
   • 🟢 Strong (80+ bits entropy)
4. Save password:
   • Click "Save" and choose location
   • Passwords stored in YYYY-MM-DD_passwords.txt format
5. Copy to clipboard:
   • Click "Copy" button (auto-clears after 30 seconds)

🗺️ Development Roadmap

✅ Completed Features

• Custom password length selection
• Password strength analysis
• Save to TXT with timestamp
• Password generation counter

🔜 Planned Features

• AES-256 encryption for stored passwords
• Password categories (Social, Banking, Work)
• Import/export password database

🔒 Security Model

Current Implementation

• Secure RNG using RNGCryptoServiceProvider
• Password strength calculation based on entropy
• Clipboard auto-clear after 30 seconds

Future Security Enhancements

// Planned encryption implementation
using System.Security.Cryptography;

byte[] EncryptPassword(string password, byte[] key, byte[] iv) {
  using Aes aes = Aes.Create();
  aes.Key = key;
  aes.IV = iv;
  
  ICryptoTransform encryptor = aes.CreateEncryptor();
  return encryptor.TransformFinalBlock(
    Encoding.UTF8.GetBytes(password), 0, password.Length);
}

• Master password protection
• PBKDF2 key derivation with 100,000 iterations
• Secure memory handling with SecureString
