НАЗВАНИЕ

       gnutls_hmac_init - API function

СИНТАКСИС

       #include <gnutls/crypto.h>

       int gnutls_hmac_init(gnutls_hmac_hd_t * dig,
       gnutls_mac_algorithm_t algorithm, const void * key, size_t
       keylen);

АРГУМЕНТЫ

       gnutls_hmac_hd_t * dig
                   is a gnutls_hmac_hd_t type

       gnutls_mac_algorithm_t algorithm
                   the HMAC algorithm to use

       const void * key
                   the key to be used for encryption

       size_t keylen
                   the length of the key

ОПИСАНИЕ

       This function will initialize an context that can be used to
       produce a Message Authentication Code (MAC) of data.  This will
       effectively use the current crypto backend in use by gnutls or
       the cryptographic accelerator in use.

       Note that despite the name of this function, it can be used for
       other MAC algorithms than HMAC.

ЗНАЧЕНИЯ, ВОЗВРАЩАЕМЫЕ ФУНКЦИЕЙ

       Zero or a negative error code on error.
