NAME
       gnutls_privkey_sign_data - API function

SYNOPSIS
       #include <gnutls/abstract.h>

       int  gnutls_privkey_sign_data(gnutls_privkey_t  signer,	gnutls_digest_algorithm_t  hash,  unsigned int flags, const gnutls_datum_t * data,
       gnutls_datum_t * signature);

ARGUMENTS
       gnutls_privkey_t signer
		   Holds the key

       gnutls_digest_algorithm_t hash
		   should be a digest algorithm

       unsigned int flags
		   Zero or on of gnutls_privkey_flags_t

       const gnutls_datum_t * data
		   holds the data to be signed

       gnutls_datum_t * signature
		   will contain the signature allocate with gnutls_malloc()

DESCRIPTION
       This function will sign the given data using a signature algorithm supported by the private  key.  Signature  algorithms  are  always  used
       together with a hash functions.	Different hash functions may be used for the RSA algorithm, but only the SHA family for the DSA keys.

       You may use gnutls_pubkey_get_preferred_hash_algorithm() to determine the hash algorithm.

RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

SINCE
       2.12.0
