import http.server

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()

server.xml server.pem

To serve on all interfaces (so other devices on the network can connect):

server_address = ('', 4443)

How to add a response : HTTP/1.1 200 Connection established\r\n\r\n when someone send a http request with CONNECT method ???

Hello!
This program works great with keys 2046 bit, but when i use key size 256 bit, program sends erroq.
Unfortionatly i need to use this size (256) can you help me to resolvw it please?

There have been some more deprecations. New version without deprecation warnings (in python 3.10 anyway) looks like this:

import http.server
import ssl

server_address = ('', 4443)
httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
ctx = ssl.SSLContext(protocol=ssl.PROTOCOL_TLS_SERVER)
ctx.load_cert_chain(certfile="server.pem", keyfile="key.pem")
httpd.socket = ctx.wrap_socket(httpd.socket, server_side=True)
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.
