# 🖼️ Secure Data Hiding in Images Using Steganography

## 🔒 Overview

This project implements **image steganography**, allowing users to hide secret messages inside images securely.  

The message is encrypted before embedding, ensuring data security.

---

## 📌 Features

- ✅ Hide secret messages inside images

- ✅ Uses **XOR encryption** for added security

- ✅ Supports **JPG & PNG** image formats

- ✅ Simple and lightweight implementation using **Python & OpenCV**

- ✅ Works on **Windows, Linux, and macOS**

---

## ⚙️ Technologies Used

- 🐍 **Python** - Core programming language

- 🖼️ **OpenCV (`cv2`)** - Image processing

- 📂 **OS Module (`os`)** - File and system operations

- 🔐 **XOR Encryption** - Encrypting secret messages before embedding

---

## 🚀 Installation & Usage

1. Install Dependencies

   Make sure Python is installed. Then, install OpenCV:

   ```bash

   pip install opencv-python

2. Run the Encoder (Hiding Message)

   ```bash

   python encryption.py

  - Enter your secret message and password.

  - The modified image (mypicencrypted.png) will be saved in the project folder.

3. Run the Decoder (Extracting Message)

   ```bash

   python decrypt.py

  - Enter the correct password to retrieve the hidden message.
