Related to that, is the framework flexible enough that it could support
public-key only hardware?  For example, I have a couple of Rainbow's
CryptoSwift cards, which only do public-key ops (no symmetric ops).

I don't know what the status of hardware info/driver availability for
those cards are these days (a few years ago, at my last job, Rainbow
was kind enough to to show us the source for their Linux driver, but
I have no clue under what terms that was), but if the crypto framework
can support them and enough info can be gathered to write a driver, I
will happily send someone a card (maybe I can even scrape up two).
