131 .IX Title "SSL_CTX_set_cert_store 3"

134 SSL_CTX_set_cert_store, SSL_CTX_get_cert_store \- manipulate X509 certificate verification storage
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/ssl.h>
142 \& void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store);
143 \& X509_STORE *SSL_CTX_get_cert_store(const SSL_CTX *ctx);
146 .IX Header "DESCRIPTION"
147 \&\fISSL_CTX_set_cert_store()\fR sets/replaces the certificate verification storage
148 of \fBctx\fR to/with \fBstore\fR. If another X509_STORE object is currently
149 set in \fBctx\fR, it will be \fIX509_STORE_free()\fRed.
151 \&\fISSL_CTX_get_cert_store()\fR returns a pointer to the current certificate
152 verification storage.
155 In order to verify the certificates presented by the peer, trusted \s-1CA\s0
156 certificates must be accessed. These \s-1CA\s0 certificates are made available
157 via lookup methods, handled inside the X509_STORE. From the X509_STORE
158 the X509_STORE_CTX used when verifying certificates is created.
160 Typically the trusted certificate store is handled indirectly via using
161 \&\fISSL_CTX_load_verify_locations\fR\|(3).
162 Using the \fISSL_CTX_set_cert_store()\fR and \fISSL_CTX_get_cert_store()\fR functions
163 it is possible to manipulate the X509_STORE object beyond the
164 \&\fISSL_CTX_load_verify_locations\fR\|(3)
167 Currently no detailed documentation on how to use the X509_STORE
168 object is available. Not all members of the X509_STORE are used when
169 the verification takes place. So will e.g. the \fIverify_callback()\fR be
170 overridden with the \fIverify_callback()\fR set via the
171 \&\fISSL_CTX_set_verify\fR\|(3) family of functions.
172 This document must therefore be updated when documentation about the
173 X509_STORE object and its handling becomes available.
175 .IX Header "RETURN VALUES"
176 \&\fISSL_CTX_set_cert_store()\fR does not return diagnostic output.
178 \&\fISSL_CTX_get_cert_store()\fR returns the current setting.
