Functions

func Decompose

func Decompose(rawBytes []byte) []fr.Element

Decompose interpret rawBytes as a bigInt x in big endian, and returns the digits of x (from LSB to MSB) when x is written in basis modulo.

func GetConstants

func GetConstants() []big.Int

GetConstants exposed to be used in gnark

func NewMiMC

func NewMiMC() hash.Hash

NewMiMC returns a MiMCImpl object, pure-go reference implementation

func Sum

func Sum(msg []byte) ([]byte, error)

Sum computes the mimc hash of msg from seed
