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.
