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