【Feature Request】Consider adding "SM4”

For more: SM2 by ISO SM2 by ISO.

Advantages in brief:

1. Much less size (fixed size to 256 bits) only, compared with RSA (2048 or 4096 bits) and ECC (128-512 bits).

2. Much faster, compared with RSA in decryption/encryption, a little faster than ECC.

3. With encryption/decryption functions/key changing with each other.

4. Free to the public.

5. Safe in use.

Where to change the topic? In fact, SM2/3/4/9 are passed by ISO and the other related orgs.
