Poly1305 implementation

Synopsis

type Ctx = State
data State
newtype Auth = Auth Bytes
authTag :: ByteArrayAccess b => b -> CryptoFailable Auth
initialize :: ByteArrayAccess key => key -> CryptoFailable State
update :: ByteArrayAccess ba => State -> ba -> State
updates :: ByteArrayAccess ba => State -> [ba] -> State
finalize :: State -> Auth
auth :: (ByteArrayAccess key, ByteArrayAccess ba) => key -> ba -> Auth

Documentation

type Ctx = State #

Deprecated: use Poly1305 State instead

Poly1305 State. use State instead of Ctx

data 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.

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 #
