Cert Human: SSL Certificates for Humans


Somebody said something about over-engineering. So I obviously had to chime in.

No, but seriously, I was in the midst of rewriting another project of mine, and I wanted to incorporate a method to get an SSL certificate from a server, show the user the same kind of information as you’d see in a browser, prompt them for validity, then write it to disk for use in further requests using requests to a server.

I was unable to find any great / easy ways that incorporated all of these concepts into one neat thing. So I made a thing.

Originally this was based off of the lovely over-engineered solution in get-ca-py by Josh Peak.

I wound up wanting a more offically supported way of patching urllib3 to have access to the certificate attributes in the raw attribute of a requests.Response object. So I wrote Replacement Connect and Response subclasses for urllib3.HTTPSConnectionPool, and a patcher, unpatcher, and context manager to enable/disable the new classes.

I also wanted some generalized utility functions to get the certificates, so I wrote some get certificate functions.

I then wanted an easier, more human way of accessing all of the information in the certificates. And that wound up turning into a whole thing. So CertStore and CertChainStore classes were born.

Python Versions Supported

I only focused on writing and testing for the latest versions of 2.7 and 3.7. It might work on other versions, have fun.
