10
11 long SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509)
12
13=head1 DESCRIPTION
14
15SSL_CTX_add_extra_chain_cert() adds the certificate B<x509> to the certificate
16chain presented together with the certificate. Several certificates
17can be added one after the other.
18
19=head1 NOTES
20
21When constructing the certificate chain, the chain will be formed from
22these certificates explicitly specified. If no chain is specified,
23the library will try to complete the chain from the available CA
24certificates in the trusted CA storage, see
25L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>.
26
27The B<x509> certificate provided to SSL_CTX_add_extra_chain_cert() will be freed by the library when the B<SSL_CTX> is destroyed. An application B<should not> free the B<x509> object.
28
29=head1 RESTRICTIONS
30
31Only one set of extra chain certificates can be specified per SSL_CTX
32structure. Different chains for different certificates (for example if both
33RSA and DSA certificates are specified by the same server) or different SSL
34structures with the same parent SSL_CTX cannot be specified using this
35function.

39SSL_CTX_add_extra_chain_cert() returns 1 on success. Check out the
40error stack to find out the reason for failure otherwise.
