• func Verify(pk *ecdsa.PublicKey, alpha, pi []byte) (beta []byte, err error)

Functions

func Prove

func Prove(sk *ecdsa.PrivateKey, alpha []byte) (beta, pi []byte, err error)

Prove constructs a VRF proof `pi` for the given input `alpha`, using the private key `sk`. The hash output is returned as `beta`.

func Verify

func Verify(pk *ecdsa.PublicKey, alpha, pi []byte) (beta []byte, err error)

Verify checks the proof `pi` of the message `alpha` against the given public key `pk`. The hash output is returned as `beta`.
