simple-https-server.py

# taken from http://www.piware.de/2011/01/creating-an-https-server-in-python/
# generate server.xml with the following command:
#    openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes
# run as follows:
#    python simple-https-server.py
# then in your browser, visit:
#    https://localhost:4443

import BaseHTTPServer, SimpleHTTPServer
import ssl

httpd = BaseHTTPServer.HTTPServer(('localhost', 4443), SimpleHTTPServer.SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket (httpd.socket, certfile='./server.pem', server_side=True)
httpd.serve_forever()

Updated to Python 3.11.4 (http.server module changes, ssl module changes/deprecations)

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()

Nice!
