@deftypefun {int} {gnutls_hash_init} (gnutls_hash_hd_t * @var{dig}, gnutls_digest_algorithm_t @var{algorithm})
@var{dig}: is a @code{gnutls_hash_hd_t}  type

@var{algorithm}: the hash algorithm to use

This function will initialize an context that can be used to
produce a Message Digest of data.  This will effectively use the
current crypto backend in use by gnutls or the cryptographic
accelerator in use.

@strong{Returns:} Zero or a negative error code on error.

@strong{Since:} 2.10.0
