SslSocketInfo.java - SSL Socket Information
How to get more information about the SSL Socket object? It is created as "SSLSocketFactory.createSocket()".
✍: FYIcenter
If you created a URL object with "new java.net.URL(...)",
you can use the following sample Java code to get more information about the URL object:
// Copyright (c) FYIcenter.com import java.net.*; import java.io.*; import javax.net.ssl.*; public class SslSocketInfo { public static void main(String[] args) throws Exception { String host = "www.oracle.com"; SSLSocketFactory factory = (SSLSocketFactory)SSLSocketFactory.getDefault(); SSLSocket socket = (SSLSocket)factory.createSocket(host, 443); socket.startHandshake(); System.out.println("SSL Socket Information"); System.out.println(" Class name: "+socket.getClass().getName()); System.out.println(" Remote address = "+socket.getInetAddress()); System.out.println(" Remote port = "+socket.getPort()); System.out.println(" Local socket address = "+socket.getLocalSocketAddress()); System.out.println(" Local address = "+socket.getLocalAddress().toString()); System.out.println(" Local port = "+socket.getLocalPort()); System.out.println(" Need client authentication = "+socket.getNeedClientAuth()); SSLSession session = socket.getSession(); System.out.println(" Cipher suite = "+session.getCipherSuite()); System.out.println(" Protocol = "+session.getProtocol()); socket.close(); } }
You can compile and run the above example in a command window:
\fyicenter>\local\jdk-1.8.0\bin\javac SslSocketInfo.java \fyicenter>\local\jdk-1.8.0\bin\java SslSocketInfo SSL Socket Information Class name: sun.security.ssl.SSLSocketImpl Remote address = www.oracle.com/23.203.120.118 Remote port = 443 Local socket address = /192.168.1.17:52840 Local address = /192.168.1.17 Local port = 52840 Need client authentication = false Cipher suite = TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 Protocol = TLSv1.2
The output confirms that:
⇒ SslCipherList.java - SSL Cipher List
⇐ SslSocketClient.java - SSL Socket Client Example
