How to view ES certificate OIDs using Python?

Question

Python

There is a CEP certificate, you need to find out what kind of oids it contains.
If you look in the system, then on the "composition" tab there is a line "improved key", there is what I need - a list of oids.
There is a fsb795 package, but I did not find the necessary methods in it
