CESI also publishes a complete white pager documenting OID assignment in details. See http://www.cesi.cn/201612/1688.html and download the pdf. Search "10197" and I see the following info:

Thanks for your great help! Once merged, I will continue the contributions to coreutils and gnulib in order to make sm3sum program eventually available.

Thanks for your quick response.

It's good that we have the OID already.
I read the Chinese document briefly, I realized that its basically equivalent to the IETF draft.

Please update your sm.c so that it includes Example 2 in the document.
Then, I will merge the code into the master of libgcrypt git repo.

After that, I will add the code for OID, examining its status. Does it work for you?

For the implementation, it looks good for me.
I have suggestions and some requests.

Suggestions:

• I think that the all test vectors in draft-shen-sm3-hash should be in sm3.c.
  
  If I read your code correctly, the "abc" in Example 1 is there. I think that the vector in Example 2 in the document should be also provided.

This is the updated patch with sm3.c. The others are not touched.

This is my note.
If it is intended to be used to OpenPGP, GCRY_MD_SM3 should be assigned in OpenPGP standard.

Thank you. The diff doesn't include sm3.c. Could you please update?
