gnutls_fingerprint(3)		    gnutls		 gnutls_fingerprint(3)

NAME
       gnutls_fingerprint - API	function

SYNOPSIS
       #include	<gnutls/gnutls.h>

       int gnutls_fingerprint(gnutls_digest_algorithm_t	algo, const gnutls_da-
       tum_t * data, void * result, size_t * result_size);

ARGUMENTS
       gnutls_digest_algorithm_t algo
		   is a	digest algorithm

       const gnutls_datum_t * data
		   is the data

       void * result
		   is the place	where the result will be copied	(may be	null).

       size_t *	result_size
		   should hold the size	of the result. The actual size of  the
		   returned result will	also be	copied there.

DESCRIPTION
       This  function  will  calculate a fingerprint (actually a hash),	of the
       given data.  The	result is not printable	data.  You should  convert  it
       to hex, or to something else printable.

       This  is	 the  usual way	to calculate a fingerprint of an X.509 DER en-
       coded certificate.  Note	however	that the  fingerprint  of  an  OpenPGP
       certificate is not just a hash and cannot be calculated with this func-
       tion.

RETURNS
       On success, GNUTLS_E_SUCCESS (0)	is returned, otherwise an  error  code
       is returned.
