Python -m http.server 443 -- with SSL?

Question

Is it possible to create a temporary Python3 HTTP server with an SSL certificate? For example:

$ python3 -m http.server 443 --certificate /path/to/cert

Answer 1

Not from the command line, but it's pretty straightforward to write a simple script to do so.

from http.server import HTTPServer, BaseHTTPRequestHandler 
import ssl
httpd = HTTPServer(('localhost', 4443), BaseHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(
    httpd.socket,
    keyfile="path/to/key.pem",
    certfile='path/to/cert.pem',
    server_side=True)
httpd.serve_forever()

If you are not restricted to the standard library and can install pip packages, there are also a number of other options, for example you can install uwsgi, which accepts command line options.

Here is what you are looking for.

# WEBSERVER with SSL support
# Create certificate files ca_key.pem and ca_cert.pem and they should be in the same folder

# Output when client connects:
# Web Server at => 192.168.1.100:4443
# 192.168.1.22 - - [12/Feb/2022 02:32:56] "GET /default.html HTTP/1.1" 200 -
import http.server
import ssl

HOST = '192.168.1.100'
PORT = 4443
Handler = http.server.SimpleHTTPRequestHandler
with http.server.HTTPServer((HOST, PORT), Handler) as httpd:
    print("Web Server listening at => " + HOST + ":" + str(PORT))
    sslcontext = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
    sslcontext.load_cert_chain(keyfile="ca_key.pem", certfile="ca_cert.pem")
    httpd.socket = sslcontext.wrap_socket(httpd.socket, server_side=True)
    httpd.serve_forever()
