#lygo NIO lygo_nio is a simple network library for client/server communication. It uses GOB for messages serialisation.

Cryptography

lygo_nio uses hybrid session encryption with PrivateKey and PublicKey.

Handshake

If Security is enabled, during handshake client and server share their PublicKey used to encrypt the Session Key.

SessionKey are used to encrypt and decrypt message body.

Transmission Protocol

It uses GOB.

Sample Usage

This example creates a server and a client. The client start pinging the server and handle “connect” and “disconnect” events.

    server := NewNioServer(10001)
	err := server.Open()
	if nil != err {
		panic(err)
	}
	fmt.Println("Server listening on port:", server.port)

	// start and stop server every 3 secs
	go func() {
		for {
			time.Sleep(5 * time.Second)
			if server.IsOpen() {
				fmt.Println("SERVER", "off")
				server.Close()
			} else {
				fmt.Println("SERVER", "on")
				server.Open()
			}
		}
	}()

	client := NewNioClient("localhost", 10001)
	client.Secure = true // enable cryptography
	client.OnConnect(func(e *lygo_events.Event) {
		fmt.Println("CLIENT", "connected")
	})
	client.OnDisconnect(func(e *lygo_events.Event) {
		fmt.Println("CLIENT", "disconnected")
	})
	err = client.Open()
	if nil != err {
		panic(err)
	}
	client.Join()
