Verifying HTTPS certificates with urllib.request

Question

I am trying to open an https URL using the urlopen method in Python 3\'s urllib.request module. It seems to work fine, but the documentation warns that \"[i]f neither

Answer 1

I found a library that does what I'm trying to do: Certifi. It can be installed by running pip install certifi from the command line.

Making requests and verifying them is now easy:

import certifi
import urllib.request

urllib.request.urlopen("https://example.com/", cafile=certifi.where())

As I expected, this returns a HTTPResponse object for a site with a valid certificate and raises a ssl.CertificateError exception for a site with an invalid certificate.
