NAME
SSL_CTX_set_cert_store, SSL_CTX_get_cert_store - manipulate X509 certificate verification storage
SYNOPSIS
#include <openssl/ssl.h>
void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store);
X509_STORE *SSL_CTX_get_cert_store(const SSL_CTX *ctx);
DESCRIPTION
SSL_CTX_set_cert_store() sets/replaces the certificate verification storage
of
ctx to/with
store. If another X509_STORE object is currently
set in
ctx, it will be
X509_STORE_free()ed.
SSL_CTX_get_cert_store() returns a pointer to the current certificate
verification storage.
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
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
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
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.
RESTRICTIONS
The X509_STORE structure used by an
SSL_CTX is used for verifying peer
certificates and building certificate chains, it is also shared by
every child
SSL structure. Applications wanting finer control can use
functions such as
SSL_CTX_set1_verify_cert_store() instead.
RETURN VALUES
SSL_CTX_set_cert_store() does not return diagnostic output.
SSL_CTX_get_cert_store() returns the current setting.
