NAME

       gnutls_hmac_init - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

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

ARGUMENTS

       gnutls_hmac_hd_t * dig
                   is a gnutls_hmac_hd_t structure.

       gnutls_digest_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

DESCRIPTION

       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.

RETURNS

       Zero or a negative value on error.

SINCE

       2.10.0
