∟SslSocketTest.java - Default SSL Socket Factory Test

This section provides a tutorial example on how to write a simple program to test the SSLSocketFactory class and the SSLServerSocketFactory class.

The following sample program shows you how to create default SSL socket factories:

import java.io.*;
import java.net.*;
import java.security.*;
import javax.net.*;
import javax.net.ssl.*;
public class SslSocketTest {
   public static void main(String[] args) {
      PrintStream out = System.out;
      out.println("\nDefault SSL socket factory:");
      try {
         // Generating the default SSLServerSocketFactory
         SSLServerSocketFactory ssf = (SSLServerSocketFactory)
            SSLServerSocketFactory.getDefault();
         System.out.println("\nSSLServerSocketFactory class: "
            +ssf.getClass());
         String[] dcsList = ssf.getDefaultCipherSuites();
         out.println("   Default cipher suites:");
         for (int i=0; i<dcsList.length; i++) {
            out.println("      "+dcsList[i]);
         }

         // Generating SSLServerSocket
         SSLServerSocket ss
            = (SSLServerSocket) ssf.createServerSocket();
         System.out.println("\nSSLServerSocket class: "
            +ss.getClass());
         System.out.println("   String: "+ss.toString());

         // Generating the default SSLSocketFactory
         SSLSocketFactory sf =
            (SSLSocketFactory) SSLSocketFactory.getDefault();
         out.println("\nSSLSocketFactory class: "
            +sf.getClass());
         dcsList = sf.getDefaultCipherSuites();
         out.println("   Default cipher suites:");
         for (int i=0; i<dcsList.length; i++) {
            out.println("      "+dcsList[i]);
         }

         // Generating SSLSocket
         SSLSocket s
            = (SSLSocket) sf.createSocket();
         System.out.println("\nSSLSocket class: "+s.getClass());
         System.out.println("   String: "+s.toString());
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
}

If you run this program, you will get something like:
