Functions

func IsValidPath

func IsValidPath(path string) bool

IsValidPath check whether or not the path has valid segments.

Types

type Key

type Key struct {
	Key       []byte
	ChainCode []byte
}

func DeriveForPath

func DeriveForPath(path string, seed []byte) (*Key, error)

DeriveForPath derives key for a path in BIP-44 format and a seed. Ed25119 derivation operated on hardened keys only.

func NewMasterKey

func NewMasterKey(seed []byte) (*Key, error)

NewMasterKey generates a new master key from seed.

func (*Key) Derive

func (k *Key) Derive(i uint32) (*Key, error)

func (*Key) PublicKey

func (k *Key) PublicKey() (ed25519.PublicKey, error)

PublicKey returns public key for a derived private key.

func (*Key) RawSeed

func (k *Key) RawSeed() [32]byte

RawSeed returns raw seed bytes

type Wallet

type Wallet struct {
	RecoveryPhrase string
}

Wallet is a BIP32 Hierarchical Deterministic Wallet based on stellar's implementation of https://github.com/satoshilabs/slips/blob/master/slip-0010.md, https://github.com/stellar/stellar-protocol/pull/63

func NewWallet

func NewWallet(entropySize int) (*Wallet, error)

NewWallet creates a new wallet with the given entropy size

func NewWalletFromRecoveryPhrase

func NewWalletFromRecoveryPhrase(mnemonic string) *Wallet

func (*Wallet) AccountAt

func (w *Wallet) AccountAt(index int, password string) (*keypair.Full, error)

type WordCount

type WordCount int

const (
	TwelveWords     WordCount = 12
	FifteenWords    WordCount = 15
	EighteenWords   WordCount = 18
	TwentyOneWords  WordCount = 21
	TwentyFourWords WordCount = 24
