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