Crypto.MAC.Poly1305

Poly1305 State. use State instead of Ctx

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.

A Poly1305 key: thirty-two bytes, and the length is checked here rather than at every use. initialize and auth take one of these and cannot fail, so a caller that holds a key does not carry an error case for a length it already knows is right.

Take thirty-two bytes for a key. A different length is reported as CryptoError_MacKeyInvalid; nothing else about a key can be wrong.

Poly1305 Auth

initialize a Poly1305 context

update a context with a bytestring

updates a context with multiples bytestring

finalize the context into a digest bytestring

One-pass authorization creation
