Functions

func New

func New() hash.Hash

New returns a new hash.Hash computing the Ascon-Hash checksum.

func Newa

func Newa() hash.Hash

Newa returns a new hash.Hash computing the Ascon-Hasha checksum.

func Sum

func Sum(data []byte) [Size]byte

Sum returns the Ascon-Hash checksum of the data.

func Suma

func Suma(data []byte) [Size]byte

Suma returns the Ascon-Hasha checksum of the data.

Types

type Xof

type Xof interface {
	// Write absorbs more data into the hash's state. It panics if called
	// after Read.
	io.Writer

	// Read squuezes more data from the hash.
	io.Reader

	// Reset resets the XOF to its initial state.
	Reset()
}

Xof defines the interface to hash functions that support arbitrary-length output.

func NewXof

func NewXof() Xof

NewXof creates a new variable-output-length hash Ascon-Xof.

func NewXofa

func NewXofa() Xof

NewXofa creates a new variable-output-length hash Ascon-Xofa.
