PixelCipher

A simple graphical user interface (GUI) tool to encode and decode hidden messages within images using steganography. This project uses Python's tkinter library for the GUI, the Pillow library for image manipulation, and supports .png and .bmp image files.

The code hides messages in images by modifying the least significant bits (LSBs) of pixel values to store binary data. During decoding, it reads these bits to reconstruct the hidden message.

Features

• Encode Message: Hide a text message within an image.
• Decode Message: Extract the hidden text message from an encoded image.
• User-friendly GUI built with tkinter.

Getting Started

Follow these instructions to set up the project on your local machine.

Prerequisites

Ensure you have Python 3.x installed. If not, download and install it from python.org.

I would also suggest suggest setting up a python environement just to keep things clean.

Installation

1. Clone the repository:

   git clone https://github.com/zeofr/PixelCipher.git

2. Install the required dependencies:

   pip install -r requirements.txt

---

Usage

1. Run the application:

   python main.py

2. Encode a message into an image:

   • Click on the Encode Image button.
   • Select an image file (.png or .bmp).
   • Enter the message you want to hide.
   • Save the encoded image.

3. Decode a message from an image:

   • Click on the Decode Image button.
   • Select the encoded image file.
   • View the hidden message in a popup window.

Notes

• The image must have enough capacity to store the message. If the message is too long, the application will notify you.
• Only .png and .bmp files are supported to ensure lossless image quality.

Example

Encoding a Message:

1. Select an image (e.g., example.png).
2. Input a message like Maki Zenin best.
3. Save the resulting encoded image as encoded_example.png.

Decoding a Message:

1. Select the encoded image (encoded_example.png).
2. View the hidden message (Maki Zenin best).
