Python Requests: .pem -> .crt + key

certificate, openssl, python-requests

Solution

There's a behaviour of requests (see documentation here) that you can take advantage of here without having to generate a `crt` or key files.

Let's say you have the `pem` file here: `/path/to/certificate.pem`, you can then do:

r = requests.get('https://example.com', verify='/path/to/cetificate.pem')

And it should work perfectly.

Problem

I've been given a .pem file for authentication on an XML POST API. I would prefer using Python Requests and have found in the documentation that I need to convert the .pem file to a server certification and key. I have been unable to find exactly what Requests needs (what kind of certification). I've had to do some openssl conversions on files before, but I'm no expert. Can anyone explain what kind of certificate and key is needed by Requests and how I can convert a .pem into those files? For more context into the Requests documentation please see http://docs.python-requests.org/en/latest/user/advanced/#ssl-cert-verification You'll notice a reference to `/path/server.crt` and `/path/key`.
