/** |
|
52 |
* A SSLEngine usage example which simplifies the presentation |
|
53 |
* by removing the I/O and multi-threading concerns. |
|
54 |
* |
|
55 |
* The test creates two SSLEngines, simulating a client and server. |
|
56 |
* The "transport" layer consists two byte buffers: think of them |
|
57 |
* as directly connected pipes. |
|
58 |
* |
|
59 |
* Note, this is a *very* simple example: real code will be much more |
|
60 |
* involved. For example, different threading and I/O models could be |
|
61 |
* used, transport mechanisms could close unexpectedly, and so on. |
|
62 |
* |
|
63 |
* When this application runs, notice that several messages |
|
64 |
* (wrap/unwrap) pass before any application data is consumed or |
|
65 |
* produced. (For more information, please see the SSL/TLS |
|
66 |
* specifications.) There may several steps for a successful handshake, |
|
67 |
* so it's typical to see the following series of operations: |
|
68 |
* |
|
69 |
* client server message |
|
70 |
* ====== ====== ======= |
|
71 |
* wrap() ... ClientHello |
|
72 |
* ... unwrap() ClientHello |
|
73 |
* ... wrap() ServerHello/Certificate |
|
74 |
* unwrap() ... ServerHello/Certificate |
|
75 |
* wrap() ... ClientKeyExchange |
|
76 |
* wrap() ... ChangeCipherSpec |
|
77 |
* wrap() ... Finished |
|
78 |
* ... unwrap() ClientKeyExchange |
|
79 |
* ... unwrap() ChangeCipherSpec |
|
80 |
* ... unwrap() Finished |
|
81 |
* ... wrap() ChangeCipherSpec |
|
82 |
* ... wrap() Finished |
|
83 |
* unwrap() ... ChangeCipherSpec |
|
84 |
* unwrap() ... Finished |
