SSL_CTX_add_extra_chain_cert(3)

NAME
SSL_CTX_add_extra_chain_cert - add certificate to chain

LIBRARY
libcrypto, -lcrypto

SYNOPSIS
 #include <openssl/ssl.h>

 long SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509)

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

NOTES
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).

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