Subject: [PATCH RFC v3 0/3] crypto: Introduce SM9 key exchange

ID-based key exchange algorithms provides the capability of using a
human-readable ID as the public key and generate corresponding private
key base on that ID. With a pre-defined pattern, the ID could be
generated with openly known knowledge of the opponent, eliminating the
need of a certificate and avoiding the whole verification chain.

Instead of CAs, ID-based crypto algorithm relies on a KGC (Key
Generation Center) for generating and distrubuting of private keys.
Unlike CAs, KGC is not directly involved in any of the crypto
procedures.

SM9 is an ID-based crypto algorithm within the ShangMi family. The key
exchange part of it was accepted in ISO/IEC 11770-3:2021. This patchset
introduces key exchange capability of SM9.

ID-based crypto algorithms are widely accepted as the next gen
asymmetric cryptography for various fileds including telecommunication,
emails, IoT etc..

You can find the technical details in the last two patch.

v3:
  Fixed cocci warnings.
v2:
  Added crypto/sm9.h which fixes build error.

GUO Zihua (3):
  MPI: Export mpi_add_ui and mpi_mod for SM9
  crypto: Introduce SM9 key exchange algorithm library
