🎥 YouTube Clone – Full Stack Java Application (Memoli)

This project was developed as the final project for an advanced programming course👨‍💻🥇. A full-featured YouTube Clone built entirely in Java, with a JavaFX client, Socket-based communication, RESTful media streaming, and MySQL database using Hibernate ORM. This application replicates the core experience of YouTube — including video playback, user interaction, and content management — with a strong emphasis on security, performance, and modular design.

Now ready to go!🎉🎉🎉

🧱 Architecture Overview

This application is built using a client-server architecture with clear separation of concerns across UI, networking, and business logic.

🔗 Communication

• Java Sockets are used for real-time communication between client and server
• Designed using a custom, structured Socket API
• All communication is encrypted to ensure privacy and integrity

📡 Media Transfer

• Videos are streamed via a Java RESTful API
• Supports byte-range (partial content) to enable seamless playback and seeking
• Videos can also be downloaded by users as needed

🔐 Security

• 🔒 Encrypted socket communication using custom RSA and AES encryption/decryption methods implemented in ServerEncryption and ClientEncryption classes to secure server-client data exchange.
• 🔑 Secure login with email-based verification
• 🛡️ Built-in checks to protect user actions and prevent data tampering

📹 Media Streaming & Download

• Videos are served via a dedicated REST API supporting:

  • HTTP byte-range for fast and smooth seeking
  • Video streaming with minimal startup delay
  • Video download for offline viewing

• The media player supports:

  • Adaptive playback speed
  • Volume control
  • Seek functionality
  • Stream without full file download

🎨User Interface (GUI)

The user interface for this project was developed using the JavaFX framework, enhanced with CSS for styling. Below are some of the key UI features:

• Responsive(all pages)
• Interactive(primary buttons|searchbar|hovering)
• Input validation before backend check(Minimums for name&username|constraints for password field)
• Shortcuts
