🔒 Image-Based Steganography Tool

📌 Overview

This project is part of the AICTE-IBM-EDUNET INTERNSHIP, providing a Steganography Tool built using Streamlit, allowing users to securely hide messages inside images. The messages are encrypted using AES or DES before being embedded, ensuring an extra layer of security.

---

✨ Features

✅ Encrypt Messages in Images - Users can encode messages inside images using AES or DES. ✅ Decrypt Messages from Images - Retrieve hidden messages securely. ✅ Custom or Auto-Generated Key - Users can enter a custom encryption key or use an automatically generated one. ✅ Download Encoded Image - Users can download the modified image with the hidden message. ✅ User-Friendly UI - Built with Streamlit for an interactive experience. ✅ Looping Video Background - Uses a high-quality looping background video for aesthetics.

Future Scope

I would be adding more features to this app , some which are decided are : - Support for more image formats - Steganography for videos - Encryption/Decryption Algorithms so that user has more options for encoding/decoding - Providing users a secure channel for efficient and safe key management 🚀 Happy Coding! 🔥
