Image Steganography with GUI in Python

Overview

This project demonstrates an image steganography tool implemented in Python. It allows users to securely hide and retrieve messages within images using a passcode for encryption and decryption. The application provides a user-friendly Graphical User Interface (GUI) built with tkinter and uses OpenCV for image manipulation. This tool supports standard image formats like .jpg and .png.

Features

• Encrypt and Decrypt Messages: Hide and retrieve secret messages inside images.
• Passcode Protection: Secure encryption and decryption using a passcode.
• GUI Interface: Simple and intuitive interface built with Python's tkinter.
• Cross-Platform: Works on Windows, macOS, and Linux.
• Image File Support: Supports .jpg, .png, .jpeg formats for encryption.
• Real-Time Status: Displays status messages for encryption and decryption.

Technologies Used

• Programming Language: Python 3.x
• Libraries:
  • tkinter for the GUI
  • opencv-python (cv2) for image manipulation
  • Pillow for handling image display in the GUI
• Platform Compatibility: Windows, macOS, Linux
• Development Environment: Any Python IDE or text editor (VS Code, PyCharm, etc.)

Installation

1. Clone the repository:

   git clone https://github.com/MrigenDeka04/Steganography-python.git

Usage

Encrypting a Message

1. Click "Open Image" to load an image from your computer. This will open a file dialog allowing you to select an image (JPG, PNG, JPEG formats are supported).
2. Enter your secret message in the "Enter Secret Message" text field.
3. Enter a passcode for encryption in the "Enter Passcode" text field. This passcode will be required later for decryption.
4. Click "Encrypt Message" to hide the message inside the image. The encrypted image will be saved as encryptedImage.jpg and displayed in the GUI.

Decrypting a Message

1. Click "Open Image" to load the encrypted image (the one generated after encryption).
2. Enter the same passcode used during encryption in the "Enter Passcode" text field.
3. Click "Decrypt Message" to reveal the hidden message. If the passcode matches, the decrypted message will be shown in a popup. If the passcode does not match, an error message will be shown.

Important Notes:

• The image file must be in a supported format (.jpg, .png, .jpeg).
• The passcode you enter during encryption must be the same passcode used for decryption, ensuring security.
• You can open and decrypt multiple images, but the passcode must match for each one to retrieve the correct hidden message.
