Functions

func Hash

func Hash(inpBI []*big.Int) (*big.Int, error)

Hash computes the Poseidon hash for the given inputs

func HashBytes

func HashBytes(msg []byte) (*big.Int, error)

HashBytes returns a sponge hash of a msg byte slice split into blocks of 31 bytes

func HashBytesX

func HashBytesX(msg []byte, frameSize int) (*big.Int, error)

HashBytesX returns a sponge hash of a msg byte slice split into blocks of 31 bytes

func HashWithState

func HashWithState(inpBI []*big.Int, initState *big.Int) (*big.Int, error)

HashWithState computes the Poseidon hash for the given inputs and initState

func New

func New(frameSize int) (hash.Hash, error)

New returns a new hash.Hash computing the Poseidon hash.

func SpongeHash

func SpongeHash(inputs []*big.Int) (*big.Int, error)

SpongeHash returns a sponge hash of inputs (using Poseidon with frame size of 16 inputs)

func SpongeHashX

func SpongeHashX(inputs []*big.Int, frameSize int) (*big.Int, error)

SpongeHashX returns a sponge hash of inputs using Poseidon with configurable frame size

func Sum

func Sum(b []byte) []byte

Sum returns the Poseidon hash of the input bytes. use frame size of 16 inputs by default
