This RFC includes:
3.3.3.  Certificate

   When a server sends the Certificate message containing the server
   certificate to the client side, several new rules are added that will
   affect the certificate selection:

   *  The public key in the certificate MUST be a valid SM2 public key.

   *  The signature algorithm used by the CA to sign the current
      certificate MUST be "sm2sig_sm3".

   *  The certificate MUST be capable of signing; e.g., the
      digitalSignature bit of X.509's Key Usage extension is set.
The object identifiers for the SM2 public key and the "sm2sig_sm3" is not 
provided.  Do these need paramters?
