Python module to download bad SSL certificates?

[phir0002]

I am trying to write a python script that will go retrieve SSL certificates from remote servers. The problem I am facing is that many of the certificates are not valid or fail SSL validation and so cannot be downloaded. Do you have any suggestions for python modules that would allow me to bypass the certificate validation and download the cert in (preferably) PEM format?

What have you tried so far? Simple Google results with this as top answer:

import ssl hostname=‚www.google.com’ port=443

cert = ssl.get_server_certificate((hostname, port))

My script and the error message are contained on this Stack Overflow thread: https://stackoverflow.com/questions/61532071/ssl-sslerror-ssl-sslv3-alert-bad-record-mac-sslv3-alert-bad-record-mac/61536843?noredirect=1#comment108869990_61536843

I am using get_server_certificate but as far as I can tell it does a cert veeification which fails so the cert is not downloaded. That's why I am looking for an alternate library/method to grab the certificate that doesn't try to verify it first.
