Functions ¶

func CRandBytes ¶

func CRandBytes(numBytes int) []byte

This uses the OS and the Seed(s).

func CRandHex ¶

func CRandHex(numDigits int) string

CRandHex returns a hex encoded string that's floor(numDigits/2) * 2 long.

Note: CRandHex(24) gives 96 bits of randomness that are usually strong enough for most purposes.

func CReader ¶

func CReader() io.Reader

Returns a crand.Reader mixed with user-supplied entropy

func MixEntropy ¶

func MixEntropy(seedBytes []byte)

Mix additional bytes of randomness, e.g. from hardware, user-input, etc. It is OK to call it multiple times. It does not diminish security.

func Sha256 ¶

func Sha256(bytes []byte) []byte

Types ¶

type Address ¶

type Address = 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 HexBytes ¶

type HexBytes []byte

The main purpose of HexBytes is to enable HEX-encoding for json/encoding.

func (HexBytes) Bytes ¶

func (bz HexBytes) Bytes() []byte

Allow it to fulfill various interfaces in light-client, etc...

func (HexBytes) Format ¶

func (bz HexBytes) Format(s fmt.State, verb rune)

func (HexBytes) Marshal ¶

func (bz HexBytes) Marshal() ([]byte, error)

Marshal needed for protobuf compatibility

func (HexBytes) MarshalJSON ¶

func (bz HexBytes) MarshalJSON() ([]byte, error)

This is the point of Bytes.

func (HexBytes) String ¶

func (bz HexBytes) String() string

func (*HexBytes) Unmarshal ¶

func (bz *HexBytes) Unmarshal(data []byte) error

Unmarshal needed for protobuf compatibility

func (*HexBytes) UnmarshalJSON ¶

func (bz *HexBytes) UnmarshalJSON(data []byte) error

This is the point of Bytes.

type PrivKey ¶

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

type PubKey ¶

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

type Symmetric ¶

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