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(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.
RETURN VALUES
SSL_CTX_set_cert_store() does not return diagnostic output.
SSL_CTX_get_cert_store() returns the current setting.
