Good point.

In fact AEAD is rather awkward because you need to do everything
in one go.  Perhaps we could adapt our kernel interface to allow
partial AEAD operations?

I want to be very careful before we pin down our user-space
interface since that's something that we cannot easily change
while the kernel interface can be modified at any time.

Thanks,
