Functions ¶

func Evaluate ¶

func Evaluate(pri *ecdsa.PrivateKey, h hash.Hash, m []byte) (index [32]byte, proof []byte)

Evaluate returns the verifiable unpredictable(random) function evaluated at m

func ProofToHash ¶

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

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

func VrfProof2Value ¶

func VrfProof2Value(curve *elliptic.CurveParams, proof []byte) []byte

func VrfProve ¶

func VrfProve(pri *ecdsa.PrivateKey, msg []byte) (proof []byte, err error)

Vrf returns the verifiable random function evaluated m and a NIZK proof func VrfProve(pri *ecdsa.PrivateKey, msg []byte) (vrfValue, vrfProof []byte, err error) {

func VrfVerify ¶

func VrfVerify(pub *ecdsa.PublicKey, msg, proof []byte) (bool, error)

Verify returns true if vrf and nizk is correct for msg func VrfVerify(pub *ecdsa.PublicKey, msg, vrfValue, vrfProof []byte) (bool, error) {
