Functions ¶
func NewPrivKeyLedgerSecp256k1 ¶
func NewPrivKeyLedgerSecp256k1(path DerivationPath) (tmcrypto.PrivKey, error)
NewPrivKeyLedgerSecp256k1 will generate a new key and store the public key for later use.
CONTRACT: The ledger device, ledgerDevice, must be loaded and set prior to any creation of a PrivKeyLedgerSecp256k1.
func RegisterAmino ¶
RegisterAmino registers all go-crypto related types in the given (amino) codec.
Types ¶
type DerivationPath ¶
type DerivationPath []uint32
DerivationPath represents a Ledger derivation path.
type LedgerSECP256K1 ¶
type LedgerSECP256K1 interface { 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 DerivationPath // contains filtered or unexported fields }
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(msg []byte) ([]byte, error)
Sign calls the ledger and stores the PubKey for future use.
Communication is checked on NewPrivKeyLedger and PrivKeyFromBytes, returning an error, so this should only trigger if the private key is held in memory for a while before use.
func (PrivKeyLedgerSecp256k1) ValidateKey ¶
func (pkl PrivKeyLedgerSecp256k1) ValidateKey() error
ValidateKey allows us to verify the sanity of a public key after loading it from disk.
