No: use strports when you want to present strings of this form as a
user-interface element, not otherwise.

To programatically configure an SSL server which requires a client certificate
use something like this:

    from twisted.internet import ssl, reactor
    reactor.listenSSL(4443, f, ssl.CertificateOptions())

Unlike the older ContextFactory classes, CertificateOptions has somewhat
more modern requirements not dictated by HTTP.  Specifically, the method
is TLSv1 and certificates are required.
