Simple HTTPS Server in Python 3 (updated to Python 3.13)

https-server.py

#!/usr/bin/env python3

# To generate a certificate use:
# openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes

from http.server import HTTPServer, SimpleHTTPRequestHandler
import ssl
from pathlib import Path

port = 4443

httpd = HTTPServer(("localhost", port), SimpleHTTPRequestHandler)
ssl_context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
ssl_context.load_cert_chain(Path(__file__).parent / "server.pem")
httpd.socket = ssl_context.wrap_socket(
    httpd.socket,
    server_side=True,
)

print(f"Serving on https://localhost:{port}")
httpd.serve_forever()

👍

I am trying this on windows 10 and Chrome browser v71.

On the chrome browser, I use "https://localhost:4443" as the URL.

and I get the following error:
Your connection is not private
NET::ERR_CERT_COMMON_NAME_INVALID

I have added the certifcate to Trusted certifcates in the browser, yet this error comes. I guess it has to do with the certificate generation and the "CN" field issued during certificate generation using the openssl

openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes

Any clues?

Ok, got it to working by following the certification generation using https://medium.freecodecamp.org/how-to-get-https-working-on-your-local-development-environment-in-5-minutes-7af615770eec. Thanks for the python script.

Thanks!
