Start a Secure Web Server with CloudFlare SSL

Tools:

• Server with ubuntu (dunno if it works with other OSes)
• Python3 (check if you have it already with python3 ––version)
• CloudFlare account
• Domain name which has SSL activated with CloudFlare NameServers

Download SSL Certificate PEM and KEY

Go to CloudFlare Dashboard > SSL > Origin Server > Create Certificate

Copy PEM and KEY into a file named cert-and-key.pem* one after the other

Create a file web-server.py* anywhere in your ubuntu server and paste that biscuit inside.

from http.server import HTTPServer, SimpleHTTPRequestHandler
import ssl

httpd = HTTPServer(('0.0.0.0', 443), SimpleHTTPRequestHandler)
httpd.socket = ssl.wrap_socket(httpd.socket, certfile='/tmp/cert-and-key.pem', server_side=True)
httpd.serve_forever()

Check the path of the pem file that created from cloudflare certificate

Then run it with sudo python3 web-server.py

Have a meditation session.

The python code is from https://piware.de/2011/01/creating-an-https-server-in-python/ and fixed by me.
