Hi Николаевич,
you are right, this is not defined in openssl, it is an engine specific functionality
as you wrote. p11-kit engine supports this command (https://github.com/OpenSC/libp11).
I'm not aware of any other method, how to load it.
As you stated, it is not a must, but since nginx is already able to load private
key from engine, it would be nice to have opportunity to load public key (certificate)
as well. In case engine doesn't support that command CMD_LOAD_CERT_CTRL, we can just
return error.
It would be good to check if the engine supports that command in following way:
const char *cmd_name = "LOAD_CERT_CTRL";
if (!ENGINE_ctrl(conn->engine, ENGINE_CTRL_GET_CMD_FROM_NAME,
0, (void *)cmd_name, NULL))
I can alter the patch if it is the only problem you can see here.
Best,
