You need to install the pyOpenSSL library to use the auth serializer.
Please install by:

    $ pip install pyOpenSSL

Sorry, but you have to configure the
    * security_key
    * security_certificate, and the
    * security_cert_storE
configuration settings to use the auth serializer.

Please see the configuration reference for more information.
