SSL_CTX_add_extra_chain_cert(3)              OpenSSL              SSL_CTX_add_extra_chain_cert(3)



NAME
       SSL_CTX_add_extra_chain_cert, SSL_CTX_clear_extra_chain_certs - add or clear extra chain
       certificates

SYNOPSIS
        #include <openssl/ssl.h>

        long SSL_CTX_add_extra_chain_cert(SSL_CTX *ctx, X509 *x509);
        long SSL_CTX_clear_extra_chain_certs(SSL_CTX *ctx);

DESCRIPTION
       SSL_CTX_add_extra_chain_cert() adds the certificate x509 to the extra chain certificates
       associated with ctx. Several certificates can be added one after another.

       SSL_CTX_clear_extra_chain_certs() clears all extra chain certificates associated with ctx.

       These functions are implemented as macros.

NOTES
       When sending a certificate chain, extra chain certificates are sent in order following the
       end entity certificate.

       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 SSL_CTX_add_extra_chain_cert() will be freed by the
       library when the SSL_CTX is destroyed. An application should not free the x509 object.

RESTRICTIONS
       Only one set of extra chain certificates can be specified per SSL_CTX structure. Different
       chains for different certificates (for example if both RSA and DSA certificates are
       specified by the same server) or different SSL structures with the same parent SSL_CTX
       cannot be specified using this function. For more flexibility functions such as
       SSL_add1_chain_cert() should be used instead.

RETURN VALUES
       SSL_CTX_add_extra_chain_cert() and SSL_CTX_clear_extra_chain_certs() return 1 on success
       and 0 for failure. Check out the error stack to find out the reason for failure.
