Functions

func RecoverAddress

func RecoverAddress(sig []byte, msg []byte) (string, error)

secp256k1 standard signature format put recid back of signature but bitcoin put it front and add 27 or 31 for uncompressed or compressed public key

func Verify

func Verify(address string, sig []byte, msg []byte) bool

Types

type Key

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

func FromBytes

func FromBytes(privateKey []byte) (*Key, error)

func FromWIF

func FromWIF(WIF string) (*Key, error)

func NewKey

func NewKey() *Key

func (Key) PublicKey
