/**
 * A SSLSocket/SSLEngine interop test case.  This is not the way to
 * code SSLEngine-based servers, but works for what we need to do here,
 * which is to make sure that SSLEngine/SSLSockets can talk to each other.
 * SSLEngines can use direct or indirect buffers, and different code
 * is used to get at the buffer contents internally, so we test that here.
 *
 * The test creates one SSLSocket (client) and one SSLEngine (server).
 * The SSLSocket talks to a raw ServerSocket, and the server code
 * does the translation between byte [] and ByteBuffers that the SSLEngine
 * can use.  The "transport" layer consists of a Socket Input/OutputStream
 * and two byte buffers for the SSLEngines:  think of them
 * as directly connected pipes.
 *
 * Again, this is a *very* simple example: real code will be much more
 * involved.  For example, different threading and I/O models could be
 * used, transport mechanisms could close unexpectedly, and so on.
 *
 * When this application runs, notice that several messages
 * (wrap/unwrap) pass before any application data is consumed or
 * produced.  (For more information, please see the SSL/TLS
 * specifications.)  There may several steps for a successful handshake,
 * so it's typical to see the following series of operations:
 *
 *      client          server          message
 *      ======          ======          =======
 *      write()         ...             ClientHello
 *      ...             unwrap()        ClientHello
 *      ...             wrap()          ServerHello/Certificate
 *      read()          ...             ServerHello/Certificate
 *      write()         ...             ClientKeyExchange
 *      write()         ...             ChangeCipherSpec
 *      write()         ...             Finished
 *      ...             unwrap()        ClientKeyExchange
 *      ...             unwrap()        ChangeCipherSpec
 *      ...             unwrap()        Finished
 *      ...             wrap()          ChangeCipherSpec
 *      ...             wrap()          Finished
 *      read()          ...             ChangeCipherSpec
 *      read()          ...             Finished
