Oooooh, hacky :-)

Sadly my impression is that pyOpenSSL development is slow at best. I've
had an issue with it a while back and was missing some feature which
someone else had already suggested. It kindof was some back and forth in
their bugtracker and then all discussion died.
IIRC (and my memory may be wrong) it was about the ability to check
signatures of one certificate against a well-defined truststore
(especially against only one to identify parent certificates by crypto).
I was frustrated back then about the indecisiveness and wrote my own
wrapper around the functions I needed and was done with it.
