NAME    [Toc]    [Back]

       SSL_load_client_CA_file - load certificate names from file

SYNOPSIS    [Toc]    [Back]

        #include <openssl/ssl.h>

        STACK_OF(X509_NAME)  *SSL_load_client_CA_file(const  char
*file);

DESCRIPTION    [Toc]    [Back]

       SSL_load_client_CA_file() reads certificates from file and
       returns a STACK_OF(X509_NAME) with the subject names
       found.

NOTES    [Toc]    [Back]

       SSL_load_client_CA_file() reads a file of PEM formatted
       certificates and extracts the X509_NAMES of the certificates
 found. While the name suggests the specific usage as
       support function for SSL_CTX_set_client_CA_list(3), it is
       not limited to CA certificates.

EXAMPLES    [Toc]    [Back]

       Load names of CAs from file and use it as a client CA
       list:

        SSL_CTX *ctx;
        STACK_OF(X509_NAME) *cert_names;

        ...
        cert_names                                              =
SSL_load_client_CA_file("/path/to/CAfile.pem");
        if (cert_names != NULL)
          SSL_CTX_set_client_CA_list(ctx, cert_names);
        else
          error_handling();
        ...

       The following return values can occur:

       NULL

           the reason.
