If another X509_STORE object is currently set in \fBctx\fR, it will be \fIX509_STORE_free()\fRed. .PP \&\fISSL_CTX_set1_cert_store()\fR sets/replaces the certificate verification storage of \fBctx\fR to/with \fBstore\fR. The \fBstore\fR's reference count is incremented. If another X509_STORE object is currently set in \fBctx\fR, it will be \fIX509_STORE_free()\fRed. .PP \&\fISSL_CTX_get_cert_store()\fR returns a pointer to the current certificate verification storage. .SH "NOTES" .IX Header "NOTES" In order to verify the certificates presented by the peer, trusted \s-1CA\s0 certificates must be accessed. These \s-1CA\s0 certificates are made available via lookup methods, handled inside the X509_STORE. From the X509_STORE the X509_STORE_CTX used when verifying certificates is created. .PP Typically the trusted certificate store is handled indirectly via using \&\fISSL_CTX_load_verify_locations\fR\|(3). Using the \fISSL_CTX_set_cert_store()\fR and \fISSL_CTX_get_cert_store()\fR functions it is possible to manipulate the X509_STORE object beyond the \&\fISSL_CTX_load_verify_locations\fR\|(3) call. .PP Currently no detailed documentation on how to use the X509_STORE object is available. Not all members of the X509_STORE are used when the verification takes place. So will e.g. the \fIverify_callback()\fR be overridden with the \fIverify_callback()\fR set via the \&\fISSL_CTX_set_verify\fR\|(3) family of functions. This document must therefore be updated when documentation about the X509_STORE object and its handling becomes available. .PP \&\fISSL_CTX_set_cert_store()\fR does not increment the \fBstore\fR's reference count, so it should not be used to assign an X509_STORE that is owned by another \s-1SSL_CTX.\s0 .PP To share X509_STOREs between two SSL_CTXs, use \fISSL_CTX_get_cert_store()\fR to get the X509_STORE from the first \s-1SSL_CTX,\s0 and then use \&\fISSL_CTX_set1_cert_store()\fR to assign to the second \s-1SSL_CTX\s0 and increment the reference count of the X509_STORE. .SH "RESTRICTIONS" .IX Header "RESTRICTIONS" The X509_STORE structure used by an \s-1SSL_CTX\s0 is used for verifying peer certificates and building certificate chains, it is also shared by every child \s-1SSL\s0 structure. Applications wanting finer control can use functions such as \fISSL_CTX_set1_verify_cert_store()\fR instead. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fISSL_CTX_set_cert_store()\fR does not return diagnostic output. .PP \&\fISSL_CTX_set1_cert_store()\fR does not return diagnostic output. .PP \&\fISSL_CTX_get_cert_store()\fR returns the current setting. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fIssl\fR\|(7), \&\fISSL_CTX_load_verify_locations\fR\|(3), \&\fISSL_CTX_set_verify\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2016 The OpenSSL Project Authors.
