NAME

6       gnutls_privkey_sign_data2 - API function
7

SYNOPSIS

9       #include <gnutls/abstract.h>
10
11       int          gnutls_privkey_sign_data2(gnutls_privkey_t         signer,
12       gnutls_sign_algorithm_t algo, unsigned int flags, const  gnutls_datum_t
13       * data, gnutls_datum_t * signature);
14

ARGUMENTS

16       gnutls_privkey_t signer
17                   Holds the key
18
19       gnutls_sign_algorithm_t algo
20                   The signature algorithm used
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 the specified signature
33       algorithm.     This     function     is     an      enhancement      of
34       gnutls_privkey_sign_data(), as it allows utilizing a alternative signa‐
35       ture algorithm where possible (e.g, use an RSA key with RSA-PSS).
36

RETURNS

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