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
