SYNOPSIS
       #include	<gnutls/crypto.h>

       int  gnutls_hmac_fast(gnutls_mac_algorithm_t  algorithm,	 const	void *
       key, size_t keylen, const void *	ptext, size_t ptext_len,  void	*  di-
       gest);

ARGUMENTS
       gnutls_mac_algorithm_t algorithm
		   the hash algorithm to use

       const void * key
		   the key to use

       size_t keylen
		   the length of the key

       const void * ptext
		   the data to hash

       size_t ptext_len
		   the length of data to hash

       void * digest
		   is the output value of the hash

DESCRIPTION
