typetype Ctx = State

Deprecated. use Poly1305 State instead

Poly1305 State. use State instead of Ctx

newtypenewtype State

Poly1305 State

This type is an instance of ByteArrayAccess for debugging purpose. Internal layout is architecture dependent, may contain uninitialized data fragments, and change in future versions. The bytearray should not be used as input to cryptographic algorithms.

valueauthTag :: ByteArrayAccess b => b -> CryptoFailable Auth

Incremental MAC Functions

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

initialize a Poly1305 context

valueupdate :: ByteArrayAccess ba => State -> ba -> State

update a context with a bytestring

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

updates a context with multiples bytestring

valuefinalize :: State -> Auth

finalize the context into a digest bytestring

One-pass MAC function

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

One-pass authorization creation
