+/**
+ * A SSLEngine usage example which simplifies the presentation
+ * by removing the I/O and multi-threading concerns.
+ *
+ * The test creates two SSLEngines, simulating a client and server.
+ * The "transport" layer consists two byte buffers: think of them
+ * as directly connected pipes.
+ *
+ * Note, 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
+ * ====== ====== =======
+ * wrap() ... ClientHello
+ * ... unwrap() ClientHello
+ * ... wrap() ServerHello/Certificate
+ * unwrap() ... ServerHello/Certificate
+ * wrap() ... ClientKeyExchange
+ * wrap() ... ChangeCipherSpec
+ * wrap() ... Finished
