Method Detail

consider

static boolean consider(String host,
               int port)
                 throws IOException

Make an effort to guess the right application protocol for STARTTLS extension, either by standard port or by interrogating the user; then obtain the appropriate protocol handler and run it.

Parameters:

host - the host to connect to

port - the port to connect to

Returns:

true if getting a certificate via STARTTLS handler is believed to be successful, false otherwise

Throws:

IOException

obtainProtocolHandlerAndRun

static boolean obtainProtocolHandlerAndRun(String handlerSuffix,
                                  String host,
                                  int port)

Load a given application specific protocol STARTTLS handler and run it.

Parameters:

handlerSuffix - the protocol handler name suffix, named after protocol itself

host - the host to connect to

port - the port to connect to

Returns:

true if getting a certificate via STARTTLS handler is believed to be successful, false otherwise
