Usage

From source file:org.kuali.mobility.push.dao.PushDaoImpl.java

private SSLSocket openConnectionToAPNS(String host, int port, String key, String passphrase) {
    SSLSocket socket;
    try {/* ww  w  .j a  v a2 s.c  om*/
        KeyStore keyStore = KeyStore.getInstance("PKCS12");

        //          keyStore.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("newcert.p12"), "strange word to use".toCharArray());
        //          keyStore.load(getClass().getResourceAsStream("/newcert.p12"), "strange word to use".toCharArray());
        //          keyStore.load(this.getClass().getClassLoader().getResourceAsStream("newcert.p12"), "strange word to use".toCharArray());

        // This works when built with Eclipse, but not when built from command line. 
        // Has to do with where the build system puts /resources/*.p12 file
        //          keyStore.load(this.getClass().getClassLoader().getResourceAsStream(key), "strange word to use".toCharArray());

        // Currently only works when read from the server's FS. Won't currently read from within eclipse project. 
        // Putting it in /opt/kme/push prevents naming conflicts. 
        keyStore.load(new FileInputStream("/opt/kme/push/newcert.p12"), "strange word to use".toCharArray());

        KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("sunx509");
        keyManagerFactory.init(keyStore, "strange word to use".toCharArray());
        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("sunx509");
        trustManagerFactory.init(keyStore);
        SSLContext sslCtx = SSLContext.getInstance("TLS");
        sslCtx.init(keyManagerFactory.getKeyManagers(), null, null);
        SSLSocketFactory sslSocketFactory = sslCtx.getSocketFactory();
        socket = (SSLSocket) sslSocketFactory.createSocket(host, port);
        socket.startHandshake();

        //Diagnostic output
        Enumeration e = keyStore.aliases();
        LOG.info(e.toString());

        LOG.info("Connected to: " + socket.getInetAddress().getHostAddress());

        String cs[] = socket.getEnabledCipherSuites();
        LOG.info("CipherSuites: " + Arrays.toString(cs));

        String ep[] = socket.getEnabledProtocols();
        LOG.info("Enabled Protocols: " + Arrays.toString(ep));

        LOG.info("Timeout: " + socket.getSoTimeout());
        LOG.info("Send Buffer Size: " + socket.getSendBufferSize());

        return socket;
    } catch (Exception e) {
