newtype Tag (s :: Symbol) a Source #

Used to tag provenance. This allows keeping the same layout as the signing documentation, passing ByteStrings everywhere, with some type guarantees.

Data.Tagged is not used for no reason other than the dependency, syntactic length, and the ToByteString instance.
