       #include <gnutls/x509.h>
       int gnutls_x509_crt_get_subject_key_id(gnutls_x509_crt_t cert, void *
       ret, size_t * ret_size, unsigned int * critical);
       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type
       void * ret  The place where the identifier will be copied

       identifier.  This is obtained by the X.509 Subject Key identifier
       extension field (2.5.29.14).

       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not
       present, otherwise a negative error value.
