It took me more time than it should have to piece together the right bits of current information for using SSL with cherrypy. Here’s a fully working example of cherrypy 3.2.0 serving up HTTPS requests.

Quick notes – if you haven’t tried cherrypy, do it. It’s awesome in its simplicity. Also, I got my SSL cert from godaddy, which was the cheapest I found. This particular cert uses a certificate chain, so when all is said and done we have my_cert.crt, my_cert.key, and gd_bundle.crt.

ssl_server.py:

import cherrypy

class RootServer:
    @cherrypy.expose
    def index(self, **keywords):
        return "it works!"

if __name__ == '__main__':
    server_config={
        'server.socket_host': '0.0.0.0',
        'server.socket_port':443,

        'server.ssl_module':'pyopenssl',
        'server.ssl_certificate':'/home/ubuntu/my_cert.crt',
        'server.ssl_private_key':'/home/ubuntu/my_cert.key',
        'server.ssl_certificate_chain':'/home/ubuntu/gd_bundle.crt'
    }

    cherrypy.config.update(server_config)
    cherrypy.quickstart(RootServer())

Launch the server like:

sudo python ssl_server.py

You need to use sudo because it runs on port 443. You should be asked to “Enter PEM pass phrase” that you set when generating your key.

Update: In a follow-up post I show how you run an HTTPS server (port 443) and an HTTP server (port 80) at the same time.
