HPKE support for AAD
Author: BrianSiposCreated Jul 20, 2026Updated Jul 21, 2026
Currently the HPKE Suite API has encrypt and decrypt argument "info" to provide KDF extra info, but does not have argument "aad" to provide AEAD input of AAD.
Without this, I am not able to validate examples from RFC 9180 which do use AAD.
