	PrivateKey *crypto.PrivateKey
}

func DecryptKey

func DecryptKey(keyjson []byte, auth string) (*Key, error)

DecryptKey returns the decrypted key via auth

func (*Key) MarshalJSON

func (k *Key) MarshalJSON() (j []byte, err error)

Marshal key to json bytes

func (*Key) UnmarshalJSON

func (k *Key) UnmarshalJSON(j []byte) (err error)

UnmarshalJSON restore key from json

KeyStore definition

func NewKeyStore

func NewKeyStore(db *db.BlockchainDB, keydir string, scryptN, scryptP int) *KeyStore

NewKeyStore new a KeyStore instance

func NewPlaintextKeyStore

func NewPlaintextKeyStore(db *db.BlockchainDB, keydir string) *KeyStore

NewPlaintextKeyStore new a PlaintextKeyStore instance

func (*KeyStore) Accounts

func (ks *KeyStore) Accounts() ([]string, error)

func (*KeyStore) Delete

func (ks *KeyStore) Delete(a accounts.Account, passphrase string) error

Delete removes the speciified account

func (*KeyStore) Find

func (ks *KeyStore) Find(addr accounts.Address) *accounts.Account

func (*KeyStore) HasAddress

func (ks *KeyStore) HasAddress(addr accounts.Address) bool

HasAddress returns if current node has the specified addr

func (*KeyStore) NewAccount

func (ks *KeyStore) NewAccount(passphrase string, accountType uint32) (accounts.Account, error)

NewAccount creates a new account

func (*KeyStore) SignHashWithPassphrase

func (ks *KeyStore) SignHashWithPassphrase(a accounts.Account, passphrase string, hash []byte) (signature []byte, err error)

SignHashWithPassphrase signs hash if the private key matching the given address can be decrypted with the given passphrase. The produced signature is in the [R || S || V] format where V is 0 or 1.

func (*KeyStore) SignTx
