Functions

func Sha256

func Sha256(bytes []byte) []byte

Types

type Address

type Address = bytes.HexBytes

An address is a []byte, but hex-encoded even in JSON. []byte leaves us the option to change the address length. Use an alias so Unmarshal methods (with ptr receivers) are available too.

func AddressHash

func AddressHash(bz []byte) Address

type PrivKey

type PrivKey interface {
	Bytes() []byte
	Sign(msg []byte) ([]byte, error)
	PubKey() PubKey
	Equals(PrivKey) bool
	Type() string
}

type PubKey

type PubKey interface {
	Address() Address
	Bytes() []byte
	VerifyBytes(msg []byte, sig []byte) bool
	Equals(PubKey) bool
	Type() string
}

type Symmetric

type Symmetric interface {
	Keygen() []byte
	Encrypt(plaintext []byte, secret []byte) (ciphertext []byte)
	Decrypt(ciphertext []byte, secret []byte) (plaintext []byte, err error)
}
