NAME
       gnutls_x509_privkey_sign_data - sign data using the private key

SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_privkey_sign_data(gnutls_x509_privkey_t  key, gnutls_digest_algorithm_t digest, unsigned int flags, const gnutls_datum_t *
       data, void * signature, size_t * signature_size);

ARGUMENTS
       gnutls_x509_privkey_t key
		   Holds the key

       gnutls_digest_algorithm_t digest
		   should be MD5 or SHA1

       unsigned int flags
		   should be 0 for now

       const gnutls_datum_t * data
		   holds the data to be signed

       void * signature
		   will contain the signature

       size_t * signature_size
		   holds the size of signature (and will be replaced by the new size)

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 SHA-1 for the DSA keys.

       If  the	buffer	provided  is  not long enough to hold the output, then *signature_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be
       returned.

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