NAME
       gnutls_x509_privkey_sign_data - API function


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
                   a key

       gnutls_digest_algorithm_t digest
                   should be a digest algorithm

       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.

       Use gnutls_x509_crt_get_preferred_hash_algorithm() to determine the hash algorithm.


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