Comment from Jim:
"8. The note for step 5 in section 6.1 is problematic from a number of
things. A) AEAD algorithms are required, so it is not clear that the
recommendation makes sense. B) there is a big difference between signing
and MACing in terms of the amount and type of integrity provided. Replacing
signing w/ AEAD loses a lot."
