Hi Ilari
I would expect that someone write HPKE specifications for all PQC algorithms.
Is someone doing this already?

HPKE presents unified API, so all that is needed is to be able to store
long-term keys with arbitrary KEM

Well, I don't really know much about PQC and don't really want to talk
about it... If you check my past posts, you will see that I have never used
the PQC algorithms as an
Ilari, Daisuke,
You guys talk a lot about how to use PQC algorithms in HPKE for use with COSE
but where are those actually described?

Hi Ilari and Hannes,
Sorry, I finally checked all of Ilari's comments and proposals today.
- Instead of registering hpke_sender to Common Header Parameters,
> register encapsulated_key:
Why is it necessary to define the encapsulated key (enc) independent of
HPKE in this COSE-HPKE spec?

I actually meant separating it in the way COSE_Mac and COSE_Sign are separated
in COSE,
Carsten,
when you say “separating AEAD from unauthenticated encryption” are you
referring to separating the storage of the tag from the encrypted ciphertext?
