Functions

func JsonString

func JsonString(data interface{}) string

func NewSeed

func NewSeed() ([]byte, error)

NewSeed returns a cryptographically secure seed

func ParseHDNum

func ParseHDNum(num uint32) uint32

将HD显示的数字转换为uint32 m/44'/60'/0'/0/account_index，如，那么传入44，将会转换为0x8000002C

func PubKeyToAddr

func PubKeyToAddr(pubKey []byte) string

Types

type Key

type Key struct {
	Key         []byte `json:"key"`          // 33 bytes
	Version     []byte `json:"version"`      // 4 bytes
	ChildNumber []byte `json:"child_number"` // 4 bytes bip44 level
	FingerPrint []byte `json:"finger_print"` // 4 bytes
	ChainCode   []byte `json:"chain_code"`   // 32 bytes
	Depth       byte   `json:"depth"`        // 1 bytes
	IsPrivate   bool   `json:"is_private"`   // unserialized
}
