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.

type AesMode

type AesMode int

AesMode AES 工作模式

const (
	// AesECB ecb 模式
	AesECB AesMode = iota
	// AesCBC cbc 模式
	AesCBC
	// AesCTR ctr 模式
	AesCTR
	// AesCFB cfb 模式
	AesCFB
	// AesOFB ofb 模式
	AesOFB
)

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
	VerifySignature(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)
}
