gnutls_hmac_init(3) gnutls gnutls_hmac_init(3)
gnutls_hmac_init - API function
#include <gnutls/crypto.h>
int gnutls_hmac_init(gnutls_hmac_hd_t * dig, gnutls_mac_algorithm_t
algorithm, const void * key, size_t keylen);
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
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.
Zero or a negative error code on error.
