Python SimpleHTTPServer with SSL

# useful for running ssl server on localhost
# which in turn is useful for working with WebSocket Secure (wss)

# copied from http://www.piware.de/2011/01/creating-an-https-server-in-python/

Python 3 version, perhaps:

from http.server import HTTPServer, SimpleHTTPRequestHandler, HTTPStatus
import ssl
# given a pem file ... openssl req -new -x509 -keyout yourpemfile.pem -out yourpemfile.pem -days 365 -nodes

httpd = HTTPServer(('localhost', 443), SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket (httpd.socket, server_side=True,
                                certfile='yourpemfile.pem')
httpd.serve_forever()

Once server gets started with above generated pem file, I got this error on Chrome (Version 88.0.4324.96 )
