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

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

Thanks for your reminding. It sounds like pretty interesting.

Currently, my though is quite simple.

• Implement SM3 in libgcrypt
• gnulib interfaces to libgcrypt to use sm3
• A new sm3sum program in coreutils interface to gnulib

I would like to extend this work, including adding SM3 to OpenPGP.

I use: 1.2.156.10197.1.401

More information:

I looked http://oidref.com/1.2.156.10197
It was registered by Chinese Cryptography Standardization Technology Committee (CCSTC) .
It is currently under control of China Electric Standard Institute: http://www.cesi.cn

I don't know if CCSTC is under 国家密码管理局 http://www.sca.gov.cn/

The CESI's OID it self seems under 200004 http://www.cesi.cn/201612/937.html

OK, I found: http://www.oidchina.cn/oid/release/1.2.156.10197.
