NAME
       gnutls_privkey_sign_hash - API function

SYNOPSIS
       #include <gnutls/abstract.h>

       int  gnutls_privkey_sign_hash(gnutls_privkey_t  signer,	gnutls_digest_algorithm_t  hash_algo,  unsigned  int flags, const gnutls_datum_t *
       hash_data, gnutls_datum_t * signature);

ARGUMENTS
       gnutls_privkey_t signer
		   Holds the signer's key

       gnutls_digest_algorithm_t hash_algo
		   The hash algorithm used

       unsigned int flags
		   Zero or one of gnutls_privkey_flags_t

       const gnutls_datum_t * hash_data
		   holds the data to be signed

       gnutls_datum_t * signature
		   will contain newly allocated signature

DESCRIPTION
       This function will sign the given hashed 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 SHA-XXX for the DSA keys.

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

       Note that if GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA flag is specified this function will ignore  hash_algo and perform a raw PKCS1 signature.

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

SINCE
       2.12.0
