The spec says:

Implementations MUST limit their scanning to the cleartext returned
from the AEAD decryption.  If a receiving implementation does not find
a non-zero octet in the cleartext, it should treat the record as
having an unexpected ContentType, sending an "unexpected_message"
alert.


But we use bad_record_mac
