[openssl-users] additional data (MAC'ed only) over TLS connection?

Hi list,

the EVP_EncryptUpdate function has the option to pass data that is
only MAC'ed but not encrypted. Is there some similar provision in the
BIO interface? I have a use case, where I'd like to "inject"
pre-encrypted/pre-mac'ed data into a TLS stream. Any suggestion on a
low-effort way to do this?

Kind regards,
