Functions ¶
func AffineToP256Point ¶
func Decrypt ¶
func Decrypt(c []byte, key *PrivateKey) ([]byte, error)
c = c1||c3||c2, len(c1)=65,len(c3)=32
func Decrypt_Old ¶
func Decrypt_Old(c []byte, key *PrivateKey) ([]byte, error)
for old version sm2 enc_dec, cause it ciphertxt = c1||c2||c3,but new c1||c3||c2
func P256 ¶
P256 returns a Curve which implements sm2 curve.
The cryptographic operations are implemented using constant-time algorithms.
func SignWithDigest ¶
func Uint64ToAffine ¶
Types ¶

func GenerateKey ¶
func GenerateKey(rand io.Reader) (*PrivateKey, error)
func GenerateKeyBySeed ¶
func GenerateKeyBySeed(rand io.Reader, seed string) (*PrivateKey, error)
go-sdk新增接口
func (*PrivateKey) Decrypt ¶
func (key *PrivateKey) Decrypt(rand io.Reader, msg []byte, opts crypto.DecrypterOpts) (plaintext []byte, err error)
