Functions

func NewChildKey

func NewChildKey(parentSecret *Secret, cPar *ChainCode, index uint32) (*Secret, *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) (*Secret, *ChainCode, error)

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

Types

type ChainCode

type ChainCode [ChainCodeSize]byte

ChainCode is a SLIP-0010 chain code.

type Secret

type Secret [SecretSize]byte

Secret is a SLIP-0010 secret.
