Abstract:

   This specification defines hybrid public-key encryption (HPKE) for
   use with CBOR Object Signing and Encryption (COSE).  HPKE offers a
   variant of public-key encryption of arbitrary-sized plaintexts for a
   recipient public key.

   HPKE works for any combination of an asymmetric key encapsulation
   mechanism (KEM), key derivation function (KDF), and authenticated
   encryption with additional data (AEAD) function.  Authentication for
   HPKE in COSE is provided by COSE-native security mechanisms or by the
   pre-shared key authenticated variant of HPKE.

   This document defines the use of the HPKE with COSE.
