       SSL_CTX_set_cert_store, SSL_CTX_get_cert_store - manipulate
 X509 certificate verification storage

LIBRARY    [Toc]    [Back]

       libcrypto, -lcrypto

SYNOPSIS    [Toc]    [Back]

        #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    [Toc]    [Back]

       SSL_CTX_set_cert_store() sets/replaces the certificate
       verification storage of ctx to/with store. If another
       X505_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    [Toc]    [Back]

       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    [Toc]    [Back]

       SSL_CTX_set_cert_store() does not return diagnostic output.


       SSL_CTX_get_cert_store() returns the current setting.
