The project involved developing a simplified Battleship game that incorporated networking fundamentals, user authentication, and basic encryption techniques.<\/p>\n\n\n\n<p>Through this assignment, I gained foundational experience in how systems communicate over a network, including establishing connections between a client and server, handling user input, and managing data transmission. The inclusion of authentication and XOR-based encryption introduced security concepts at a practical level, reinforcing how even simple systems can implement basic protections.<\/p>\n\n\n\n<p>This project strengthened my understanding of how programming, networking, and security intersect, and it provided early experience with structured problem-solving in a technical environment.
