NAME

       SSL_load_client_CA_file - load certificate names from file


SYNOPSIS

        #include <openssl/ssl.h>

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


DESCRIPTION

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


NOTES

       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

       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();
        ...


RETURN VALUES

       The following return values can occur:

       NULL
           The operation failed, check out the error stack for the reason.

       Pointer to STACK_OF(X509_NAME)
           Pointer to the subject names of the successfully read certificates.
