🔐 Secure Data Encryption with Streamlit

This is a simple yet powerful Streamlit web application that allows users to securely encrypt and decrypt personal data like name, email, and message using the Fernet symmetric encryption method from the cryptography library.

🚀 Features

• 🔐 Encrypt user data with a custom passkey.
• 📦 Save encrypted data locally.
• 🔓 Decrypt and retrieve data securely using the same passkey.
• 🔒 Prevents unauthorized access (invalid key = no data).
• 🌐 Beautiful and interactive UI using Streamlit.
