Image Steganography Using LSB Technique

A simple Python-based steganography project that hides a secret message and passcode in an image using Least-Significant-Bit (LSB) encoding, and later retrieves the message securely.

Overview

This project uses robust LSB steganography to embed a secret message along with a passcode into an image. It consists of two Python scripts with user-friendly GUIs built using Tkinter.

Features

• Encryption:
  Embeds a secret message and passcode into mypic.jpg and saves the result as encrypted.png.

• Decryption:
  Retrieves the hidden message from encrypted.png when the correct passcode is provided.

• User-Friendly GUI:
  Easy-to-use interfaces for both encryption and decryption processes.

• Robust Data Storage:
  Uses a header to store the lengths of the passcode and message for accurate extraction.

Requirements

• Python 3.x
• OpenCV
• NumPy
• Tkinter (usually included with Python)

Installation

1. Clone the repository.
2. Install the required libraries:

   pip install opencv-python numpy

3. Place an image mypic.jpg in project directory
