NAME

       gnutls_x509_crl_get_authority_key_id - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crl_get_authority_key_id(gnutls_x509_crl_t  crl,  void  *  id,  size_t  *
       id_size, unsigned int * critical);

ARGUMENTS

       gnutls_x509_crl_t crl
                   should contain a gnutls_x509_crl_t type

       void * id   The place where the identifier will be copied

       size_t * id_size
                   Holds the size of the result field.

       unsigned int * critical
                   will be non-zero if the extension is marked as critical (may be null)

DESCRIPTION

       This function will return the CRL authority's key identifier.  This  is  obtained  by  the
       X.509  Authority Key identifier extension field (2.5.29.35).  Note that this function only
       returns the keyIdentifier field of the extension and  GNUTLS_E_X509_UNSUPPORTED_EXTENSION,
       if  the  extension  contains  the  name and serial number of the certificate. In that case
       gnutls_x509_crl_get_authority_key_gn_serial() may be used.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in  case  of
       an error.

SINCE

       2.8.0
