}

HDPrivateKey HD private key include a ecdsa private key and a chain code

func GenerateMaster

func GenerateMaster() (*HDPrivateKey, error)

GenerateMaster generate a master private key with chain code

func GenerateMasterBySeed

func GenerateMasterBySeed(seed *big.Int) (*HDPrivateKey, error)

GenerateMasterBySeed generate a master private key with chain code by seed

func PrivateToPrivate

func PrivateToPrivate(parentPrivkey *HDPrivateKey, index *big.Int) *HDPrivateKey

PrivateToPrivate derive private key by private key using index

type HDPublicKey
