🔐 Secure Image Steganography 👨‍💻

Full Stack Cybersecurity Project for Secure Data Hiding

Built using:

---

📍 Overview

This project is a cybersecurity web application that hides secret messages inside images.

👉 First, the message is encrypted using a password (AES encryption)
👉 Then, it is hidden inside an image (steganography)

The final image looks normal, but it contains hidden data 🔐

🧠 How It Works

1. User uploads an image
2. User enters message + password
3. Message is encrypted (AES)
4. Encrypted data is hidden in image
5. Image is downloaded

For decoding:

• Upload image + enter password
• System extracts and decrypts message
