Usage

From source file:dualcontrol.CryptoClientDemo.java

private void call(Properties properties, MockableConsole console, String hostAddress, int port, byte[] data)
        throws Exception {
    Socket socket = SSLContexts.create(false, "cryptoclient.ssl", properties, console).getSocketFactory()
            .createSocket(hostAddress, port);
    DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
    dos.writeShort(data.length);
    dos.write(data);//from   w w  w  . ja  v a2 s  .c  o m
    dos.flush();
    DataInputStream dis = new DataInputStream(socket.getInputStream());
    byte[] ivBytes = new byte[dis.readShort()];
    dis.readFully(ivBytes);
    byte[] bytes = new byte[dis.readShort()];
