• Add new credentials (site, username, password)
• Secure AES-based encryption (via cryptography.fernet)
• View stored passwords (decrypted live)
• JSON vault storage (vault.json)
• CLI interface for interaction
• Key security via vault.key (ignored by Git)
• 🔐 Master password protection (added in v2)

🔐 Master Password System

This password vault is protected by a master password to prevent unauthorized access.

🛠️ Setup (Run Once):

python master_password.py

You'll be prompted to create your master password.
It will be encrypted and saved to a file named master.key.

⚠️ Important: The master.key file is automatically excluded by .gitignore.
Do not push it to GitHub or share it — it unlocks your entire vault.

🔓 Unlocking the Vault

Whenever you run:

python vault.py

You'll need to enter your master password before accessing or managing saved credentials.
