All,
I've got a "perfect vs. good" question.
NIST is pushing RSA-2048. And I think we all agree that's probably a
good thing.
However, performance on RSA-2048 is too low for a number of real world
uses.
Assuming RSA-2048 is unavailable, is it worth taking the intermediate
step of using RSA-1280? Or should we stick to RSA-1024?
