Image Steganography Tool

This Python-based GUI tool enables you to encode and decode secret messages within image files using LSB (Least Significant Bit) steganography.

Features

• Encoding: Embeds text messages into selected image files using LSB steganography.
• Decoding: Retrieves hidden messages from encoded image files.
• Capacity Calculation: Automatically calculates the maximum number of characters that can be encoded into a chosen image.
• User Interface: Provides a simple and intuitive graphical interface for ease of use.

Requirements

• Python 3.x
• tkinter (included in standard Python installation)
• Pillow (PIL fork for handling images) pip install Pillow

Installation

1. Clone the repository:

   git clone https://github.com/your_username/image-steganography-tool.git
   cd image-steganography-tool
   

Usage

1. Encoding a Message:

• Launch the application by running python steganography.py.
• Click on Encode Message.
• Select an image file (.png, .jpg, .jpeg) where you want to hide the message.
• Enter your secret message in the provided text box.
• Click Save to choose the location and filename for the encoded image or this may save in Download Folder by Default.

3. Decoding a Message:

• Launch the application by running python steganography.py.
• Click on Decode Message.
• Select the encoded image file (.png, .jpg, .jpeg) from which you want to extract the hidden message.
• The decoded message will be displayed in a message box.

Acknowledgments

The tool utilizes the Pillow library for image processing. Inspired by the concept of LSB steganography for hiding information within digital media.
