SSL_CTX_add_extra_chain_certadd certificate to chain

#include <openssl/ssl.h>

SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509);

() adds the certificate x509 to the certificate chain presented together with the certificate. Several certificates can be added one after the other.

When constructing the certificate chain, the chain will be formed from these certificates explicitly specified. If no chain is specified, the library will try to complete the chain from the available CA certificates in the trusted CA storage, see SSL_CTX_load_verify_locations(3).

The x509 certificate provided to () will be freed by the library when the SSL_CTX is destroyed. An application free the x509 object.

SSL_CTX_add_extra_chain_cert() returns 1 on success. Check out the error stack to find out the reason for failure otherwise.
