Functions

func ComputeMastersFromSeed

func ComputeMastersFromSeed(seed []byte) (secret [32]byte, chainCode [32]byte)

ComputeMastersFromSeed returns the master public key, master secret, and chain code in hex.

func DerivePrivateKeyForPath

func DerivePrivateKeyForPath(privKeyBytes [32]byte, chainCode [32]byte, path string) ([32]byte, error)

DerivePrivateKeyForPath derives the private key by following the BIP 32/44 path from privKeyBytes, using the given chainCode.

Types

type BIP44Params

type BIP44Params struct {
	// contains filtered or unexported fields
}

BIP44Params wraps BIP 44 params (5 level BIP 32 path). To receive a canonical string representation ala m / purpose' / coin_type' / account' / change / address_index call String() on a BIP44Params instance.

func NewFundraiserParams

func NewFundraiserParams(account uint32, addressIdx uint32) *BIP44Params

NewFundraiserParams creates a BIP 44 parameter object from the params: m / 44' / 389' / account' / 0 / address_index The fixed parameters (purpose', coin_type', and change) are determined by what was used in the fundraiser.

func NewParams

func NewParams(purpose, coinType, account uint32, change bool, addressIdx uint32) *BIP44Params

NewParams creates a BIP 44 parameter object from the params: m / purpose' / coin_type' / account' / change / address_index

func NewParamsFromPath

func NewParamsFromPath(path string) (*BIP44Params, error)

Parse the BIP44 path and unmarshal into the struct. nolint: gocyclo

func (BIP44Params) DerivationPath

func (p BIP44Params) DerivationPath() []uint32

Return the BIP44 fields as an array.

func (BIP44Params) String

func (p BIP44Params) String() string
