NAME

6       gnutls_privkey_sign_hash - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int          gnutls_privkey_sign_hash(gnutls_privkey_t          signer,
12       gnutls_digest_algorithm_t  hash_algo,   unsigned   int   flags,   const
13       gnutls_datum_t * hash_data, gnutls_datum_t * signature);
14

ARGUMENTS

16       gnutls_privkey_t signer
17                   Holds the signer's key
18
19       gnutls_digest_algorithm_t hash_algo
20                   The hash algorithm used
21
22       unsigned int flags
23                   zero for now
24
25       const gnutls_datum_t * hash_data
26                   holds the data to be signed
27
28       gnutls_datum_t * signature
29                   will contain newly allocated signature
30

DESCRIPTION

32       This  function  will sign the given hashed data using a signature algo‐
33       rithm supported by the private key.  Signature  algorithms  are  always
34       used  together  with a hash functions.  Different hash functions may be
35       used for the RSA algorithm, but only SHA-XXX for the DSA keys.
36
37       Use  gnutls_x509_crt_get_preferred_hash_algorithm()  to  determine  the
38       hash algorithm.
39

RETURNS

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