5SSL_CTX_set_cert_store, SSL_CTX_get_cert_store - manipulate X509 certificate verification storage
6
7=head1 SYNOPSIS
8
9 #include <openssl/ssl.h>
10
11 void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store);
12 X509_STORE *SSL_CTX_get_cert_store(const SSL_CTX *ctx);
13
14=head1 DESCRIPTION
15
16SSL_CTX_set_cert_store() sets/replaces the certificate verification storage
17of B<ctx> to/with B<store>. If another X509_STORE object is currently
18set in B<ctx>, it will be X509_STORE_free()ed.
19
20SSL_CTX_get_cert_store() returns a pointer to the current certificate
21verification storage.
22
23=head1 NOTES
24
25In order to verify the certificates presented by the peer, trusted CA
26certificates must be accessed. These CA certificates are made available
27via lookup methods, handled inside the X509_STORE. From the X509_STORE
28the X509_STORE_CTX used when verifying certificates is created.
29
30Typically the trusted certificate store is handled indirectly via using
31L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>.
32Using the SSL_CTX_set_cert_store() and SSL_CTX_get_cert_store() functions
33it is possible to manipulate the X509_STORE object beyond the
34L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>
35call.
36
37Currently no detailed documentation on how to use the X509_STORE
38object is available. Not all members of the X509_STORE are used when
39the verification takes place. So will e.g. the verify_callback() be
40overridden with the verify_callback() set via the
41L<SSL_CTX_set_verify(3)|SSL_CTX_set_verify(3)> family of functions.
42This document must therefore be updated when documentation about the
43X509_STORE object and its handling becomes available.

46
47SSL_CTX_set_cert_store() does not return diagnostic output.
48
49SSL_CTX_get_cert_store() returns the current setting.
