Types

type AlgorithmOption

type AlgorithmOption string

const (
	// Secp256k1 secp256k1 algorithm
	Secp256k1 AlgorithmOption = "Secp256k1"
	// Secp256r1 secp256r1 algorithm
	Secp256r1 AlgorithmOption = "Secp256r1"
)

type PrivateKey

type PrivateKey struct {
	K *ecdsa.PrivateKey
}

type PublicKey

type PublicKey struct {
	// contains filtered or unexported fields
}

PublicKey ECDSA public key. never new(PublicKey), use NewPublicKey()

func (*PublicKey) Address
