⚙️ Installation & Setup

1️⃣ Clone Repository

git clone https://github.com/your-username/Video-Cryptography.git
cd Video-Cryptography

---

2️⃣ Configure Java & Maven

Make sure you have:

• Java 21
• Maven 3.9+

Installed on your system.

Check versions:

java -version
mvn -version

---

3️⃣ Install Dependencies

mvn clean install

---

4️⃣ Run the Application

mvn spring-boot:run

Application will start on:

http://localhost:8080

---

🐳 Docker Setup

Build Docker Image

docker build -t video-cryptography .

Run Docker Container

docker run -p 8080:8080 video-cryptography

---

🔐 How It Works

1. Upload a video file
2. Frames are extracted using OpenCV
3. Encryption algorithm secures video frames
4. Encrypted data is processed and stored
5. Decryption reconstructs original video securely

---

🧪 Testing

Run all tests:

mvn test

Testing includes:

• Unit Testing
• Integration Testing
• API Validation
• Batch Processing Tests

---

📸 Application Screenshots

🏠 Home Page

The main interface where users can upload a video and start the encryption/decryption process.

---

📤 Video Upload

The uploaded video is displayed successfully before encryption.

---

🔐 Encryption & 🔓 Decryption Results

The system encrypts the uploaded video using AES and then successfully decrypts it to recover the original video.

📸 Applications
