Incremental MAC Functions

initialize :: ByteArrayAccess key => key -> CryptoFailable State

initialize a Poly1305 context

update :: ByteArrayAccess ba => State -> ba -> State

update a context with a bytestring

updates :: ByteArrayAccess ba => State -> [ba] -> State

updates a context with multiples bytestring

finalize :: State -> Auth

finalize the context into a digest bytestring

One-pass MAC function

auth :: (ByteArrayAccess key, ByteArrayAccess ba) => key -> ba -> Auth

One-pass authorization creation
