=head1 NAME
|
|
|
|
SSL_CTX_set_cert_store, SSL_CTX_get_cert_store - manipulate X509 certificate verification storage
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store);
|
|
X509_STORE *SSL_CTX_get_cert_store(SSL_CTX *ctx);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_CTX_set_cert_store() sets/replaces the certificate verification storage
|
|
of B<ctx> to/with B<store>. If another X509_STORE object is currently
|
|
set in B<ctx>, it will be X509_STORE_free()ed.
|
|
|
|
SSL_CTX_get_cert_store() returns a pointer to the current certificate
|
|
verification storage.
|
|
|
|
=head1 NOTES
|
|
|
|
In order to verify the certificates presented by the peer, trusted CA
|
|
certificates must be accessed. These CA 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.
|
|
|
|
Typically the trusted certificate store is handled indirectly via using
|
|
L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>.
|
|
Using the SSL_CTX_set_cert_store() and SSL_CTX_get_cert_store() functions
|
|
it is possible to manipulate the X509_STORE object beyond the
|
|
L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>
|
|
call.
|
|
|
|
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 verify_callback() be
|
|
overridden with the verify_callback() set via the
|
|
L<SSL_CTX_set_verify(3)|SSL_CTX_set_verify(3)> family of functions.
|
|
This document must therefore be updated when documentation about the
|
|
X509_STORE object and its handling becomes available.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_CTX_set_cert_store() does not return diagnostic output.
|
|
|
|
SSL_CTX_get_cert_store() returns the current setting.
