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.
