Functions

func NewPrivKeyLedgerSecp256k1

func NewPrivKeyLedgerSecp256k1(path hd.BIP44Params) (tmcrypto.PrivKey, error)

NewPrivKeyLedgerSecp256k1 will generate a new key and store the public key for later use.

func RegisterAmino

func RegisterAmino(cdc *amino.Codec)

RegisterAmino registers all go-crypto related types in the given (amino) codec.

Types

type LedgerSECP256K1

type LedgerSECP256K1 interface {
	Close() error
	GetPublicKeySECP256K1([]uint32) ([]byte, error)
	SignSECP256K1([]uint32, []byte) ([]byte, error)
}

LedgerSECP256K1 reflects an interface a Ledger API must implement for the SECP256K1 scheme.

type PrivKeyLedgerSecp256k1

type PrivKeyLedgerSecp256k1 struct {
	// CachedPubKey should be private, but we want to encode it via
	// go-amino so we can view the address later, even without having the
	// ledger attached.
	CachedPubKey tmcrypto.PubKey
	Path         hd.BIP44Params
}

PrivKeyLedgerSecp256k1 implements PrivKey, calling the ledger nano we cache the PubKey from the first call to use it later.

func (*PrivKeyLedgerSecp256k1) AssertIsPrivKeyInner

func (pkl *PrivKeyLedgerSecp256k1) AssertIsPrivKeyInner()

AssertIsPrivKeyInner implements the PrivKey interface. It performs a no-op.

func (PrivKeyLedgerSecp256k1) Bytes

func (pkl PrivKeyLedgerSecp256k1) Bytes() []byte

Bytes implements the PrivKey interface. It stores the cached public key so we can verify the same key when we reconnect to a ledger.

func (PrivKeyLedgerSecp256k1) Equals

func (pkl PrivKeyLedgerSecp256k1) Equals(other tmcrypto.PrivKey) bool

Equals implements the PrivKey interface. It makes sure two private keys refer to the same public key.

func (PrivKeyLedgerSecp256k1) PubKey

func (pkl PrivKeyLedgerSecp256k1) PubKey() tmcrypto.PubKey

PubKey returns the cached public key.

func (PrivKeyLedgerSecp256k1) Sign

func (pkl PrivKeyLedgerSecp256k1) Sign(message []byte) ([]byte, error)

Sign returns a secp256k1 signature for the corresponding message

func (PrivKeyLedgerSecp256k1) ValidateKey

func (pkl PrivKeyLedgerSecp256k1) ValidateKey() error

ValidateKey allows us to verify the sanity of a public key after loading it from disk.
