🔐 stego-xor-rgb-encoder

A simple and educational steganography tool for hiding encrypted text inside RGB images using XOR encryption and ASCII encoding.

---

📌 Overview

stego-xor-rgb-encoder allows you to:

1. Encrypt a secret text using XOR cipher with a user-provided key.
2. Embed the encrypted text into the pixel values of an RGB image.
3. Extract and Decrypt the hidden message using the same key.

This combines encryption and steganography in a lightweight, easy-to-understand way.

🚀 Quick Start

📥 Clone this repo:

git clone https://github.com/arshc0der/stego-xor-rgb-encoder.git
cd stego-xor-rgb-encoder

⚙️ Run the Notebook:

Open StegnoRGBImplementation.ipynb in Jupyter and follow the step-by-step instructions.

💡 Usage Example

secret_text = "hello"
encryption_key = "key123"

• Encrypt and embed each character via XOR using the key.
• Embedded values are hidden inside pixel channels.
• Extract and decrypt using the same key.
