Java Network Programming & Encryption

This course is designed for developers who want to master network programming in Java while learning how to secure data transmission using encryption. Throughout the course, you'll build real client-server applications using Java Sockets, understanding how data flows between machines over a network. You'll learn how to establish connections, send and receive data, and handle multiple clients concurrently. Beyond basic networking, this course dives deep into encryption — you'll implement AES encryption to protect data in transit, ensuring that sensitive information exchanged over your network remains secure from eavesdropping and tampering. By combining network programming with practical encryption techniques, you'll be equipped to build secure, production-ready networked applications — a skill set highly valued in backend development, cybersecurity-aware systems, and distributed applications. By the end of this course, you'll be able to design, implement, and secure client-server communication in Java with confidence.
