I wrote a code in java to get list of supported protocols. Case 1. This code when runs at my local returns protocols: SSLv2Hello, SSLv3, TLSv1, TLSv1.1, TLSv1.2 And I can decide which protocol to use. My Local environment is: Windows 7, jdk1.7.0_45

Case 2. When I run same code on 2 separate linux machines (java 1.7.0_40-b43 & java 1.6.0_41) and both return only SSLv2Hello, SSLv3, TLSv1

Java code:

    if (!(socket instanceof SSLSocket)) {
        return socket;
    }
    SSLSocket sslSocket = (SSLSocket) socket;
    for (String protocol : sslSocket.getSupportedProtocols()) {
            System.out.println(protocol);
    }

Any idea what needs to be done to get TLSv1.1, TLSv1.2 as supported protocols in Case 2 above.

Thanks

which java providers are you using? oracle and openjdk? – nandsito Nov 15 '16 at 13:55
Java by oracle, For jdk 1.7 it is not a problem now - I figured out things wrong at my end, but for jdk 1.6 I am still not getting TLSv1.1 and TLSv1.2 as available protocols. – TechRoute Nov 22 '16 at 13:13
take a look http://stackoverflow.com/questions/33364100/how-to-use-tls-1-2-in-java-6 – nandsito Nov 22 '16 at 15:04
TLS 1.1 is available in oracle java 6 update 111, and TLS 1.2, in java 6 update 121 – nandsito Nov 22 '16 at 15:07
Right, I have an old version. Many thanks – TechRoute Nov 24 '16 at 13:32
