As i understand the process, i think it would be necessary to pass all
the data through the card in order to for the card to know which type of
signature it was making.
I know nothing of the details of how these cards are implemented,
though. Maybe they do this already? it seems like performance would be
problematic if you were signing something like a multi-MiB document,
given the speed of most smartcards.
Maybe one of the folks with experience implementing these devices can
give more concrete details?
