You mean `enc` ? In the case of DHKems, a public key represented as opaque bytes.
In the case of PQKems some other opaque bytes. And our decision not to use `application/jwk+json` or `application/cose-key` to represent this part when HPKE is translated for JOSE and COSE ? I'm happy to comment on that part as well.
