Thanks for your replay! Sorry for my wrong format and I would use plaint-text in the future.
As for “in which case it will use the public key as a stand-in for the missing private key”, do you mean use “client cert public key” instead of “client cert private key”? If so is it possible that I pass “client cert public key” in “SSL_CTX_use_PrivateKey_file”? (I’m running on 1.1 :(((( )

Your problem is here, you can't skip loading some form of private
key handle. OpenSSL 1.1.1 provides an SSL_CTX_use_cert_and_key()
function, which allows the private key to passed as NULL, in which
case it will use the public key as a stand-in for the missing private
key. All the relevant functions are in ssl/ssl_rsa.c, if you are
willing to read the source code to find the most suitable interface.
If you're using 1.1.0 or 1.0.2 there is probably another way, but
I don't know it off-hand.
