I don't recall; I think Jeremy knows most about these issues.
Personally, I expect that even if we could get certification, it would
be much easier if there was no encryption code at all in Python, and
if people had to get it from a 3rd party site.

Rotor should be deprecated regardless; I've never heard of someone
using it.
