/** |
|
35 |
* This class provides a simple way for servers to support conventional |
|
36 |
* use of the Secure Sockets Layer (SSL). Application code uses an |
|
37 |
* SSLServerSocketImpl exactly like it uses a regular TCP ServerSocket; the |
|
38 |
* difference is that the connections established are secured using SSL. |
|
39 |
* |
|
40 |
* <P> Also, the constructors take an explicit authentication context |
|
41 |
* parameter, giving flexibility with respect to how the server socket |
|
42 |
* authenticates itself. That policy flexibility is not exposed through |
|
43 |
* the standard SSLServerSocketFactory API. |
|
44 |
* |
|
45 |
* <P> System security defaults prevent server sockets from accepting |
|
46 |
* connections if they the authentication context has not been given |
|
47 |
* a certificate chain and its matching private key. If the clients |
|
48 |
* of your application support "anonymous" cipher suites, you may be |
|
49 |
* able to configure a server socket to accept those suites. |
