Several certificates 1772613Skriscan be added one after the other. 1872613Skris 1972613Skris=head1 NOTES 2072613Skris 2172613SkrisWhen constructing the certificate chain, the chain will be formed from 2272613Skristhese certificates explicitly specified. If no chain is specified, 2372613Skristhe library will try to complete the chain from the available CA 2472613Skriscertificates in the trusted CA storage, see 2572613SkrisL<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>. 2672613Skris 27269686SjkimThe 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. 28269686Sjkim 29269686Sjkim=head1 RESTRICTIONS 30269686Sjkim 31269686SjkimOnly one set of extra chain certificates can be specified per SSL_CTX 32269686Sjkimstructure. Different chains for different certificates (for example if both 33269686SjkimRSA and DSA certificates are specified by the same server) or different SSL 34269686Sjkimstructures with the same parent SSL_CTX cannot be specified using this 35269686Sjkimfunction. 36269686Sjkim 3772613Skris=head1 RETURN VALUES 3872613Skris 3972613SkrisSSL_CTX_add_extra_chain_cert() returns 1 on success.
