NAME
SSL_CTX_set_cert_store,
SSL_CTX_set1_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);
void
SSL_CTX_set1_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 the verification storage of ctx to or replaces it
with store. If another
X509_STORE object is currently set in
ctx, it will be freed.
SSL_CTX_set1_cert_store()
sets the verification storage of ctx to or replaces it
with store. The store's
reference count is incremented.
SSL_CTX_get_cert_store()
returns a pointer to the current certificate verification storage.
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, for example, 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.
RETURN VALUES
SSL_CTX_get_cert_store() returns the
current setting.
