Implementing 2-way SSL in Java using TLS and Self Signed Certificates part2

Step 2: The server (Get the complete server code here)

Requires the Trustore/Keystore created in Step-1.

To write the server process in Java is pretty simple. You just have to do a couple of steps:
Specify a couple of properties so that the Trustore/Keystore can be loaded like the following code fragment shows:



Create the ServerSocket as anSSLServerSocketlike the following code fragment shows:
char ksPass[] = "welcome".toCharArray();
char ctPass[] = "welcome".toCharArray();

//Create and load the Keystore
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream("ianalyzer.jks"), ksPass);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, ctPass);

//Create the ServerSocket as an SSLServerSocket
SSLContext secureSocket = SSLContext.getInstance("TLS");
secureSocket.init(kmf.getKeyManagers(), null, null);
SSLServerSocketFactory ssf = secureSocket.getServerSocketFactory();
ssocket = (SSLServerSocket) ssf.createServerSocket(8095);
SSLServerSocket ss = (SSLServerSocket) ssocket;

//This explicitly states TLS with 2-way authentication
