Functions

func GeneratePrivateKey

func GeneratePrivateKey(keystorePath string) (*sm2.PrivateKey, error)

GeneratePrivateKey creates an SM2 private key using SM2P256V1 curve and stores it in keystorePath.

func LoadPrivateKey

func LoadPrivateKey(keystorePath string) (*sm2.PrivateKey, error)

LoadPrivateKey loads a private key from a file in keystorePath. It looks for a file ending in "_sk" and expects a PEM-encoded PKCS8 EC private key.

Types

type SM2Signature

type SM2Signature struct {
	R, S *big.Int
}

type SM2Signer

type SM2Signer struct {
	PrivateKey *sm2.PrivateKey
}

SM2Signer 实现 crypto.Signer 接口

func (*SM2Signer) Public

func (s *SM2Signer) Public() crypto.PublicKey

Public returns the *sm2.PublicKey associated with PrivateKey.

func (e *ECDSASigner) Public() crypto.PublicKey {
	return &e.PrivateKey.PublicKey
}

func (*SM2Signer) Sign

func (s *SM2Signer) Sign(rand io.Reader, msg []byte, opts crypto.SignerOpts) ([]byte, error)

Sign returns SM2 signature in form of DER marshalized via ASN1
