Get Hasher：
func NewSM3Hasher() *Hasher
Computational hash：
func (h *Hasher) Hash(msg []byte) (hash []byte, err error)
Encrypt：
func (ea *SM4) Encrypt(key, originMsg []byte) (encryptedMsg []byte, err error)
Decrypt：
func (ea *SM4) Decrypt(key, encryptedMsg []byte) (originMsg []byte, err error)
Generate private key：
func GenerateSM2Key() (SM2PrivateKey, error)
signature：
func (key *SM2PrivateKey) Sign(_ []byte, digest []byte) ([]byte, error)
verify：
func (id *ID) Verify(_ []byte, signature, msg []byte) (valid bool, err error)
generate signature：
func (sm9 *SM9) Sign(k []byte, msg []byte) (signature []byte, err error)
verify：
func (sm9 *SM9) Verify(k []byte, signature, msg []byte) (valid bool, err error)
