These classes provide the interface between a :cpp:class:`Ssl::Session` and an appropriate adapter.
Error codes are implementation specific, however 0 always indicates success and < 0 for error.
To obtain a description for an error code, use :cpp:func:`Ssl::Connection::getErrorString`.
SSL Alerts are reported via error codes. To obtain the alert code call
:cpp:func:`Ssl::Connection::getAlert` which returns an :cpp:enum:`Ssl::Alert` code.
If the error code is not an alert then Alert::INVALID is returned.
