Image Steganography Toolkit

A Python-based steganography tool that enables users to securely hide secret text messages inside digital images. Using OpenCV for image processing, the tool embeds messages into image pixel values and allows authorized users to retrieve them using a passcode.

Features

• 🔒 Hide secret text messages within image files
• 🖼️ Uses image pixel manipulation for data embedding
• 🔑 Passcode-protected message retrieval
• ⚡ Lightweight and easy to use
• 💻 Cross-platform support (Windows, Linux, macOS)
• 🐍 Built with Python and OpenCV

Technologies Used

• Python 3
• OpenCV (cv2)
• Image Processing
• Steganography
• Cybersecurity Fundamentals

Installation

Clone the Repository

git clone https://github.com/Hunter-Sploit/Image-Steganography-Toolkit.git
cd Image-Steganography-Toolkit

Install Dependencies

pip install opencv-python

Usage

Run the Program

python stego.py

Encoding a Message

1. Enter the secret message you want to hide.
2. Provide a passcode.
3. The message is embedded into the image.
4. A new file named encryptedImage.jpg is generated.

Decoding a Message

1. Run the script.
2. Enter the correct passcode.
3. The hidden message is extracted and displayed.

How It Works

The tool hides data inside image pixels using a simple steganographic technique:

1. Converts each character of the secret message into its ASCII value.
2. Stores the values within RGB pixel channels.
3. Traverses image pixels and embeds the message.
4. Reconstructs the original text during decoding after passcode verification.
