Functions

func Evaluate

func Evaluate(k *ecdsa.PrivateKey, m []byte) (index [32]byte, proof []byte)

Evaluate returns the verifiable unpredictable function evaluated at m

func H1

func H1(m []byte) (x, y *big.Int)

H1 hashes m to a curve point

func H2

func H2(m []byte) *big.Int

H2 hashes to an integer [1,N-1]

func ProofToHash

func ProofToHash(pk *ecdsa.PublicKey, m, proof []byte) (index [32]byte, err error)

ProofToHash asserts that proof is correct for m and outputs index.

func Prove

func Prove(secret *big.Int, params *GeneralBulletSetup) (bulletproofs.ProofBPRP, error)
