SM2 can be tested with the L<openssl-speed(1)> application since version 3.0.
Currently, the only valid algorithm name is B<sm2>.
Since version 3.0, SM2 keys can be generated and loaded only when the domain
parameters specify the SM2 elliptic curve.

This example demonstrates the calling sequence for using an B<EVP_PKEY> to verify

possible to import an SM2 key with domain parameters other than the SM2 elliptic
curve ones.
Validation of SM2 keys has been separated from the validation of regular EC
keys, allowing to improve the SM2 validation process to reject loaded private
