Twisted https

Hi, I have a twisted application. I want it to work on top of https instead of http. Where can I find a good example for this?

All you have to do is use reactor.listenSSLinstead reactor.listenTCP. http://twistedmatrix.com/documents/current/core/howto/ssl.html reveals the basics reactor.listenSSL.

Here is an example of a twisted server running on SSL with basic authentication:

#!/usr/bin/env python

USERS={'admin': 'admin', 
        'user': 'user',
        'test': 'eW91IGFyZSBjcmF6eQo='}

"""
Twisted SSL webserver with basic authentication using plain in-memory passwords. 
The first argument is the path of the directory to serve; if not provided then the current folder is used (".").

INSTALL DEPENDENCIES:
    pip install twisted
    pip install pyOpenSSL
    pip install service_identity

GENERATE SSL CERTIFICATES:
    mkdir ~/.ssl && cd ~/.ssl
    openssl genrsa > privkey.pem
    openssl req -new -x509 -key privkey.pem -out cacert.pem -days 9999

USAGE:
    Requires running as root (normal users cannot bind to ports below 1024); 
    login with test_user/test_password

    sudo python twisted-web-ssl.py     # serve the current folder
    sudo python twisted-web-ssl.py /home

HTTPS - HTTP SSL. HTTPS = HTTP + SSL/TLS. . http://twistedmatrix.com/documents/13.0.0/core/howto/ssl.html#auto1 http://twistedmatrix.com/documents/13.0.0/web/howto/using-twistedweb.html#auto2

from twisted.internet import reactor, ssl
