@karel-m SM4 has become an ISO/IEC standard in 2021, see https://www.iso.org/standard/81564.html for details.

Besides, linux kernel and openssl also support SM4, so maybe this pr is suitable for libtom/libtomcrypt

This PR needs a bit of love. I'm willing to fork it and have it catch up, unless @ChaoWeiAtGit is going to.

... considering that @ChaoWeiAtGit hasn't been github active for a long time, a takeover seems the way forward.
