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 cafile nor capath is specified, an HTTPS request will not do any verification of the server’s certificate".
I am guessing I need to specify one of those parameters if I don't want my program to be vulnerable to man-in-the-middle attacks, problems with revoked certificates, and other vulnerabilities.
cafile and capath are supposed to point to a list of certificates. Where am I supposed to get this list from? Is there any simple and cross-platform way to use the same list of certificates that my OS or browser uses?
