As discussed at IETF 114, the HPKE draft uses the COSE_Key public key representation.  The authors described that Ilari Liusvaara had proposed using a different public key representation, which is detailed in Slide 2 of https://datatracker.ietf.org/meeting/114/materials/slides-114-cose-cose-hpke-00.  As recorded in the minutes<https://datatracker.ietf.org/doc/minutes-114-cose/>, consensus during the meeting appeared to be in favor of continuing to use COSE_Key.

This note initiates a consensus call by the chairs on the topic of what public key format the COSE HPKE specification will use.  Working group members are requested to express their preferences within two weeks of this note (by Thursday, September 6th) for either:

1.  Continuing to use COSE_Key
2.  Using the different format proposed by Ilari Liusvaara
3.  Other (please describe in sufficient detail to enable its specification)

                                                       Thank you,
                                         -- Mike (for the COSE chairs)
