Types

type ChainCode

type ChainCode [ChainCodeSize]byte

ChainCode is a SLIP-0010 chain code.

func NewChildKey

func NewChildKey(parentSigner signature.Signer, cPar ChainCode, index uint32) (signature.Signer, ChainCode, error)

NewChildKey derives a child key and chain code from a (parent key, parent chain code, index) tuple.

func NewMasterKey

func NewMasterKey(seed []byte) (signature.Signer, ChainCode, error)

NewMasterKey derives a master key and chain code from a seed byte sequence.
