Functions

func Hash

func Hash(pi []byte) []byte

Hash converts proof(pi) into vrf output(hash) without verifying it

func Prove

func Prove(pk []byte, sk []byte, m []byte) (pi, hash []byte, err error)

assume <pk, sk> were generated by ed25519.GenerateKey() Prove generates vrf output and corresponding proof(pi) with secret key

func Verify

func Verify(pk []byte, pi []byte, m []byte) (bool, error)

[]byte(message) Verify checks if the proof is correct or not

Types

type CachedGroupElement

type CachedGroupElement struct {
	Z, T2d edwards25519.FieldElement
	// contains filtered or unexported fields
}
