xmlrpc acts at the application layer and ssl at the transport layer so
they can inter operate easily as long as you do not use the
certificate to authenticate the client but only validate the server
and encrypt data (which you can also do but it is more complicated)

One option for you is to use web2py which include an xmlrpc server
that uses a wsgi ssl enabled web server.

Here is how:

1) Install web2py
2) Visit http://127.0.0.1:8000/admin and create a new application from
the web based IDE
3) create your web service for example, in a controller default.py

     @service.xmlrpc
     def add(a,b): return int(a)+int(b)

4) Restart web2py with

     python web2py.py -a ADMIN_PASSWD -c SSL_CERTIFICATE -k
SSL_PRIVATE_KEY -i 0.0.0.0 -p 443

5) You can now access the service from any Python program:

     >>> import xmlrpclib
     >>> server_url = 'https://myserver:443/yourapp/default/call/
xmlrpc'
     >>> server = xmlrpclib.Server(server_url)
     >>> print server.add(3,4)
     7

Hope this helps.
