Crypto.MAC.Poly1305

Description

Poly1305 implementation

Synopsis

Documentation

type Ctx = State Source #

Deprecated: use Poly1305 State instead

Poly1305 State. use State instead of Ctx

data State Source #

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.
