@greyarea@mitra.vpclmulqdq.moe I assume this is "Authentication Using an Asymmetric Key" (https://www.rfc-editor.org/rfc/rfc9180.html#name-authentication-using-an-asy)? Because in "Encryption to a Public Key" mode, sender's key is not used. If I understand the idea correctly, the ephemeral key would need to be added to fep0806:cipherData. That is, instead of encap_key | ciphertext it will be ephemeral_key_pub | encap_key | ciphertext.
