Functions ¶

func Sign ¶

func Sign(randReader io.Reader, priv *PrivateKey, h hash.Hash, M []byte) (r, s *big.Int, err error)

Sign data using K generated randomly like in crypto/ecdsa packages.

func SignUsingK ¶

func SignUsingK(k *big.Int, priv *PrivateKey, h hash.Hash, M []byte) (r, s *big.Int, err error)

Sign data using K Specified

func Verify ¶

func Verify(pub *PublicKey, h hash.Hash, M []byte, r, s *big.Int) bool

Types ¶

type PrivateKey ¶

type PrivateKey struct {
	PublicKey
	D *big.Int
}

func GenerateKey ¶

func GenerateKey(c elliptic.Curve, randReader io.Reader) (*PrivateKey, error)

Generate the paramters

func (*PrivateKey) Public ¶ added in v1.2.2

func (priv *PrivateKey) Public() crypto.PublicKey

Public returns the public key corresponding to priv.

type PublicKey ¶

type PublicKey struct {
	elliptic.Curve

	X *big.Int
	Y *big.Int
}

func (*PublicKey) Equal ¶ added in v1.2.2

func (pub *PublicKey) Equal(x crypto.PublicKey) bool

Equal reports whether pub and x have the same value.
