How do I verify an SSL certificate in python?

Question

I need to verify that a certificate was signed by my custom CA. Using OpenSSL command-line utilities this is easy to do:

# Custom CA file: ca-cert.pem
# Cer         


        

Answer 1

Like you said, OpenSSL requires connection

M2Crypto doesn't have good verification

How about this ingenious idea:

import os 
os.system('openssl verify -CAfile ../ca-cert.pem bob.cert')

Its ugly, but it works!
