🌟 About StegoForge

StegoForge is a Secure Image Steganography Platform developed using Python, Flask, Pillow, and Modern Cryptography.

The application enables users to securely communicate by hiding secret messages inside images while using Elliptic Curve Diffie-Hellman (ECDH) for secure key exchange and authenticated access.

It combines Steganography, Cryptography, and Web Security into one modern application.

🎯 Why StegoForge?

Traditional messaging applications expose communication over networks.

StegoForge enhances privacy by combining two security layers:

✅ Cryptography

✅ Steganography

Instead of sending encrypted text directly, messages are first encrypted and then hidden inside an image, making the communication significantly harder to detect.
