Functions ¶

func CRandBytes ¶

func CRandBytes(numBytes int) []byte

This uses the OS and the Seed(s).

func CRandHex ¶

func CRandHex(numDigits int) string

RandHex(24) gives 96 bits of randomness, 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 Register ¶

func Register(name string, driver Crypto)

func Ripemd160 ¶

func Ripemd160(bytes []byte) []byte

func Sha256 ¶

func Sha256(bytes []byte) []byte

func Sm3Hash ¶

func Sm3Hash(msg []byte) []byte

Types ¶

type Crypto ¶

	GenKey() (PrivKey, error)
	SignatureFromBytes([]byte) (Signature, error)
	PrivKeyFromBytes([]byte) (PrivKey, error)
	PubKeyFromBytes([]byte) (PubKey, error)
}

func New ¶

func New(name string) (c Crypto, err error)

type PrivKey ¶

}

type PubKey ¶

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

type Signature ¶

	Bytes() []byte
	IsZero() bool
	String() string
