Those containing a \fB1\fR increment the reference count of the supplied store so it must be freed at some point after the operation. Those containing a \fB0\fR do not increment reference counts and the supplied store \fB\s-1MUST NOT\s0\fR be freed after the operation. .SH "NOTES" .IX Header "NOTES" The stores pointers associated with an \s-1SSL_CTX\s0 structure are copied to any \s-1SSL\s0 structures when \fBSSL_new()\fR is called. As a result \s-1SSL\s0 structures will not be affected if the parent \s-1SSL_CTX\s0 store pointer is set to a new value. .PP The verification store is used to verify the certificate chain sent by the peer: that is an \s-1SSL/TLS\s0 client will use the verification store to verify the server's certificate chain and a \s-1SSL/TLS\s0 server will use it to verify any client certificate chain. .PP The chain store is used to build the certificate chain. .PP If the mode \fB\s-1SSL_MODE_NO_AUTO_CHAIN\s0\fR is set or a certificate chain is configured already (for example using the functions such as \&\fBSSL_CTX_add1_chain_cert\fR\|(3) or \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3)) then automatic chain building is disabled. .PP If the mode \fB\s-1SSL_MODE_NO_AUTO_CHAIN\s0\fR is set then automatic chain building is disabled. .PP If the chain or the verification store is not set then the store associated with the parent \s-1SSL_CTX\s0 is used instead to retain compatibility with previous versions of OpenSSL. .SH "RETURN VALUES" .IX Header "RETURN VALUES" All these functions return 1 for success and 0 for failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3) \&\fBSSL_CTX_set0_chain\fR\|(3) \&\fBSSL_CTX_set1_chain\fR\|(3) \&\fBSSL_CTX_add0_chain_cert\fR\|(3) \&\fBSSL_CTX_add1_chain_cert\fR\|(3) \&\fBSSL_set0_chain\fR\|(3) \&\fBSSL_set1_chain\fR\|(3) \&\fBSSL_add0_chain_cert\fR\|(3) \&\fBSSL_add1_chain_cert\fR\|(3) \&\fBSSL_CTX_build_cert_chain\fR\|(3) \&\fBSSL_build_cert_chain\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" These functions were first added to OpenSSL 1.0.2.
