Establishing Https connection

[nenad.cikic at gmail.com]

Hello,
Once I get my xml populated I have to send it to web service.
Should I use httplib?
I am reading the docs and I have managed to open the connection with 
httplib.HTTPSConnection(host[, port[, key_file[, cert_file[, strict[, timeout[, source_address]]]]]])
After that i intend to use
HTTPConnection.request('POST', url[, body[, headers]])

During opening it asks me for the password. I see that the urllib class has prompt_user_passwd() that can be overriden for the password supply, so that no console action is necessary, but with httplib how is done?
My questions are:
-am I using the right class?
-i intend to store certificate and private key in database, but how can I use them without saving back to file?

I have already developed applications for http/https but not in python, so I need some hint to point me in the right direction.

Thanks 
Nenad
