jiazhang added a comment to T3454: Hash SM3 support.

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 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?
