A simple interactive command-line password manager written in Python that securely encrypts and stores your credentials using Fernet symmetric encryption.

• 🔐 Master password protected
• 🧠 Credentials stored locally in encrypted vault.json
• 🔒 Uses strong AES-128 encryption with Fernet
• 🧪 Interactive CLI for adding, viewing, and listing credentials

• Python 3.7+
• cryptography library
