SSL_CTX_set_cert_store(3)           OpenSSL          SSL_CTX_set_cert_store(3)

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.
