Netty Echo Server/Client - SSL doesn't work

netty http server example
netty client example
netty architecture
netty performance tuning
netty udp server
netty close connection
netty based http server
netty bootstrap

I want to add SSL to messages and I go to see the example of netty from there.

Ex: Echo Server

public final class EchoServer {

static final boolean SSL = System.getProperty("ssl") != null;
static final int PORT = Integer.parseInt(System.getProperty("port", "8007"));

public static void main(String[] args) throws Exception {
    // Configure SSL.
    final SslContext sslCtx;
    if (SSL) {
        SelfSignedCertificate ssc = new SelfSignedCertificate();
        sslCtx = SslContextBuilder.forServer(ssc.certificate(), ssc.privateKey()).build();
    } else {
        sslCtx = null;}

I have some problems. I don't realize the System.getProperty("ssl") what means? I test this code and get my "SSL" is null, why? I also use wireshark to fetch the connection, but didn't get ssl connection.

use this:

static final boolean SSL = System.getProperty("ssl") != null;   
static final String HOST = System.getProperty("host", "127.0.0.1");   
static final int PORT = Integer.parseInt(System.getProperty("port", SSL? "8443" : "8080"));

If you want to enable SSL in this example you should start it with "-Dssl" which will enable SSL for the example.

Netty itself also includes some scripts to make it easier when you checkout the source from git:

./run-example.sh -Dssl echo-server
./run-example.sh -Dssl echo-client

Unlike DISCARD and ECHO servers, we need a client for the TIME protocol because a human cannot translate a 32-bit binary data into a date on a calendar. In this section, we discuss how to make sure the server works correctly and learn how to write a client with Netty.

you can use;

static final boolean SSL = true;

static final int PORT = Integer.parseInt(System.getProperty("port", SSL? "8443" : "8080"));

Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server. 'Quick and easy' doesn't mean that a resulting application will suffer from a maintainability or a performance

Reactor Netty Reference Guide, The Reactor Netty reference guide is available as HTML documents. To start a TCP server, you must create and configure a TcpServer instance. In order to send data to a connected client, you must attach an I/O handler. When you need SSL or TLS, you can apply the configuration shown in the next  This Scala library is convenient for creating network server and client, useful for quickly writing server and client tests. This library doesn't try to be robust. If you want long running robust server or client, you should try other things. This library is small, the only dependency is Netty. Features. HTTP: Server.
