Features

• Encryption

  • AES-256
  • RSA

• Encrypted RCON

  • AES-256 key is send with RSA
  • Messages are encrypted with AES-256
  • Build-in RconClient and RconServer classes

Example Usage

RconClient

public static void main(String[] args) throws Exception {
    try (RconClient client = RconClient.connect("localhost", 25570)) {
        if (client.authenticate("Ch4ng3-M3")) {
            client.sendCommand("say hello");
        } else {
            System.out.println("Failed to authenticate");
        }
    }
}

RconServer

public static void main(String[] args) throws Exception {
    RconServer rconServer = new RconServer(
            25570,
            "Ch4ng3-M3",
            new CommandHandler()
    );
}

MessageHandler

This class is called when the server receives a message

public class CommandHandler implements MessageHandler {
    @Override
    public String[] handleMessage(String message) {
        LOGGER.info("Received message: {}", message);
        
        return new String[] { "hello" };
    }
}
