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.
