To track this, I created a ticket at: https://dev.gnupg.org/T3454


Could you please send the patch to gcrypt-devel?  Or, you can upload

Out of curiosity, is it mandated by the goverment?  If so, how about
SM2?

When I read FIDO U2F document in this April, I learned about optional

We don't have a practice to use GitHub, which might require non-free
JavaScript.

Please read libgcrypt/doc/HACKING, the "How to contribute" section,
especially the "License policy" subsection.
