NAME

6       gnutls_privkey_sign_data - API function
7

SYNOPSIS

9       #include <gnutls/abstract.h>
10
11       int gnutls_privkey_sign_data(gnutls_privkey_t signer, gnutls_digest_al‐
12       gorithm_t hash,  unsigned  int  flags,  const  gnutls_datum_t  *  data,
13       gnutls_datum_t * signature);
14

ARGUMENTS

16       gnutls_privkey_t signer
17                   Holds the key
18
19       gnutls_digest_algorithm_t hash
20                   should be a digest algorithm
21
22       unsigned int flags
23                   Zero or one of gnutls_privkey_flags_t
24
25       const gnutls_datum_t * data
26                   holds the data to be signed
27
28       gnutls_datum_t * signature
29                   will contain the signature allocated with gnutls_malloc()
30

DESCRIPTION

32       This function will sign the given data using a signature algorithm sup‐
33       ported by the private key. Signature algorithms  are  always  used  to‐
34       gether with a hash functions.  Different hash functions may be used for
35       the RSA algorithm, but only the SHA family for the DSA keys.
36
37       You may use gnutls_pubkey_get_preferred_hash_algorithm()  to  determine
38       the hash algorithm.
39

RETURNS

41       On  success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er‐
42       ror value.
