📝 Description

Password Manager is a console utility for securely storing your passwords. All passwords are encrypted using Fernet (cryptography library) and stored locally. The program also includes a password generator and a strength checker.

Features:

• 🔒 Encryption — Passwords are stored in encrypted form
• 🔑 Key-based access — A unique key is generated on first launch
• 🗑️ Delete password — Remove stored passwords you no longer need
• ✏️ Update password — Change existing passwords with ease
• 🎲 Password generator — Create strong random passwords
• 📊 Strength checker — Evaluate password reliability
• 💾 Local storage — All data stays on your computer

🎮 How to Use

1. Run the program
2. Choose an action from the menu:
   • Save a new password
   • Delete a password
   • View all saved passwords
   • Generate a random password
