SSL_CTX_SET_CERT_STORE(3)           OpenSSL          SSL_CTX_SET_CERT_STORE(3)
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/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_set1_cert_store() sets/replaces the certificate verification
       storage of ctx to/with store. The store's reference count is
       incremented.  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.
       SSL_CTX_set_cert_store() does not increment the store's reference
       count, so it should not be used to assign an X509_STORE that is owned
       by another SSL_CTX.
       To share X509_STOREs between two SSL_CTXs, use SSL_CTX_get_cert_store()
       to get the X509_STORE from the first SSL_CTX, and then use
       SSL_CTX_set1_cert_store() to assign to the second SSL_CTX and increment
       the reference count of the X509_STORE.
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_set1_cert_store() does not return diagnostic output.
       SSL_CTX_get_cert_store() returns the current setting.
