data encryption
Private identifiers can be encrypted AND signed before being written to the badge.
The reader will decrypt and authenticate the private identifier thus protected, before sending it
to its output media. Only a correctly decrypted and authenticated identifier will produce an exit
code, otherwise the reader will remain silent.
The encryption-authentication uses the mode MtE (MAC Then Encrypt).
