Features

• User Registration & Authentication: Secure user registration and login using AES encryption for passwords.
• Real-Time Messaging: Instant messaging with real-time updates.
• User Status Management: Real-time updates of user statuses (online, offline, busy).
• Secure Communication: AES encryption to secure passwords and chat messages.
• Responsive UI: User-friendly and responsive interface designed with JavaFX.
