Python 3 Simple HTTPS server

python3_https_server.py

#!/usr/bin/env python3
# python3 update of https://gist.github.com/dergachev/7028596
# Create a basic certificate using openssl: 
#     openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes
# Or to set CN, SAN and/or create a cert signed by your own root CA: https://thegreycorner.com/pentesting_stuff/writeups/selfsignedcert.html

import http.server
import ssl

httpd = http.server.HTTPServer(('127.0.0.1', 443), http.server.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket (httpd.socket, certfile='./server.pem', server_side=True)
httpd.serve_forever()

I am on Python 3.11.2 and I see a warning when running this script:

python3_https_server.py:11: DeprecationWarning: ssl.wrap_socket() is deprecated, use SSLContext.wrap_socket()
  httpd.socket = ssl.wrap_socket (httpd.socket, certfile='./server.pem', server_side=True)

I fix this warning with the following script:

#!/usr/bin/env python3
# python3 update of https://gist.github.com/dergachev/7028596
# Create a basic certificate using openssl: 
#     openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes
# Or to set CN, SAN and/or create a cert signed by your own root CA: https://thegreycorner.com/pentesting_stuff/writeups/selfsignedcert.html

import http.server
import ssl

httpd = http.server.HTTPServer(('127.0.0.1', 443), http.server.SimpleHTTPRequestHandler)
ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
ctx.load_cert_chain(certfile='./server.pem')
httpd.socket = ctx.wrap_socket(httpd.socket, server_side=True)
httpd.serve_forever()

Thanks @lxylxy123456

If server.crt server.key are separate, use this to load

ctx.load_cert_chain(certfile='server.crt', keyfile='server.key')
