Are you really talking about the Rivest-Shamir-Adleman public key
encryption algorithm? What are you using it for?

Can uswsusp resume without help from an initrd or initramfs? If not that
would be a rather bad short-term disadvantage. I can use suspend2 just
with a bare kernel. Only on suspend some userspace preparation is needed.
