# generate server.pem with the following command:
#    openssl req -new -x509 -keyout key.pem -out server.pem -days 365 -nodes
# run as follows:

import http.server
import ssl

server_address = ('localhost', 4443)
httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket,
                               server_side=True,
                               certfile="server.pem",
                               keyfile="key.pem",
                               ssl_version=ssl.PROTOCOL_TLS)
httpd.serve_forever()

None of these worked for me, but twistd -no web --path=. --https=443 -c cert.pem -k key.pem did. Can be installed via pip install twisted. I was able to use a Let's Encrypt certificate generated by certbot so it can be used across the internet.
