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