144 SSL_CTX_add_extra_chain_cert \- add certificate to chain
146 .IX Header "SYNOPSIS"
148 \& #include <openssl/ssl.h>
151 \& long SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509)
154 .IX Header "DESCRIPTION"
155 \&\fISSL_CTX_add_extra_chain_cert()\fR adds the certificate \fBx509\fR to the certificate
156 chain presented together with the certificate. Several certificates
157 can be added one after the other.
160 When constructing the certificate chain, the chain will be formed from
161 these certificates explicitly specified. If no chain is specified,
162 the library will try to complete the chain from the available \s-1CA\s0
163 certificates in the trusted \s-1CA\s0 storage, see
164 SSL_CTX_load_verify_locations(3).
166 .IX Header "RETURN VALUES"
167 \&\fISSL_CTX_add_extra_chain_cert()\fR returns 1 on success. Check out the
168 error stack to find out the reason for failure otherwise.
