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 one of gnutls_privkey_flags_t

       const gnutls_datum_t * data
                   holds the data to be signed

       gnutls_datum_t * signature
                   will contain the signature allocated 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
