SSL_CTX_set0_chain_cert_store() and SSL_CTX_set1_chain_cert_store() set the certificate store used for certificate chain building to B. SSL_set0_verify_cert_store(), SSL_set1_verify_cert_store(), SSL_set0_chain_cert_store() and SSL_set1_chain_cert_store() are similar except they apply to SSL structure B. All these functions are implemented as macros. Those containing a B<1> increment the reference count of the supplied store so it must be freed at some point after the operation. Those containing a B<0> do not increment reference counts and the supplied store B be freed after the operation. =head1 NOTES The stores pointers associated with an SSL_CTX structure are copied to any SSL structures when SSL_new() is called. As a result SSL structures will not be affected if the parent SSL_CTX store pointer is set to a new value. The verification store is used to verify the certificate chain sent by the peer: that is an SSL/TLS client will use the verification store to verify the server's certificate chain and a SSL/TLS server will use it to verify any client certificate chain. The chain store is used to build the certificate chain. If the mode B is set or a certificate chain is configured already (for example using the functions such as L or L) then automatic chain building is disabled. If the mode B is set then automatic chain building is disabled. If the chain or the verification store is not set then the store associated with the parent SSL_CTX is used instead to retain compatibility with previous versions of OpenSSL. =head1 RETURN VALUES All these functions return 1 for success and 0 for failure. =head1 SEE ALSO L, L L L L L L L L L L L =head1 HISTORY These functions were added in OpenSSL 1.0.2. =head1 COPYRIGHT Copyright 2013-2016 The OpenSSL Project Authors.
