Thank you! This can be easily extended to handle https requests by adding
httpd.socket = ssl.wrap_socket(httpd.socket, server_side=True, keyfile="key.pem", certfile='cert.pem')
after line 36. However, ssl.wrap_socket() is deprecated. Does anyone know how to do this with SSLContext.wrap_socket()?

I tried with

context = ssl.create_default_context()
context.load_cert_chain(certfile='cert.pem', keyfile="key.pem")

but then context.wrap_socket(httpd.socket, server_side=True) complains about "check_hostname requires server_hostname". Adding a hostname, it complains that hostnames can only be used in client mode.

@maiphi any luck in getting the https to work ?

Seeing your question, I just looked into it again. This should do the job (note that I did only a very quick test):

context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
context.load_cert_chain('cert.pem', 'key.pem')
httpd.socket = context.wrap_socket(httpd.socket, server_side=True)

Note that except for the deprecation warning the version using ssl.wrap_socket() works fine, too.

wonderful! many, many, many thanks 👌
