Types

type CipherKey

type CipherKey struct {
	Data   string `json:"data"`
	Cipher string `json:"cipher"`
}

type Key

type Key interface {
	// Bytes returns a serialized, storable representation of this key
	Bytes() ([]byte, error)

	// Type represent the type of key
	Type() KeyType
}

type KeyStore

type KeyStore struct {
	Type   KeyType    `json:"type"`
	Cipher *CipherKey `json:"cipher"`
}

func (*KeyStore) Pretty

func (key *KeyStore) Pretty() (string, error)

type KeyType

type KeyType int

type PrivateKey

type PrivateKey interface {
	Key

	// Sign signs digest using key k.
	Sign(digest []byte) ([]byte, error)

	// Return a public key paired with this private key
	PublicKey() PublicKey
}

PrivateKey represents a private key that can be used to generate a public key and sign data

type PublicKey

type PublicKey interface {
	Key

	// Address gets address from public key
	Address() (*types.Address, error)

	// Verify that 'sig' is the signed hash of 'data'
	Verify(digest []byte, sig []byte) (bool, error)
}

PublicKey is a public key that can be used to verify data signed with the corresponding private key

type SymmetricKey

type SymmetricKey interface {
	Key

	// Encrypt encrypts plain text using symmetric key.
	Encrypt(plain []byte) (cipher []byte, err error)

	// Decrypt decrypts ciphertext using symmetric key.
	Decrypt(cipher []byte) (plain []byte, err error)
}

SymmetricKey is a interface that provides symmetric encrypt and decrypt.
