NAME

6       gnutls_x509_privkey_generate - API function
7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int       gnutls_x509_privkey_generate(gnutls_x509_privkey_t       key,
12       gnutls_pk_algorithm_t algo, unsigned int bits, unsigned int flags);
13

ARGUMENTS

15       gnutls_x509_privkey_t key
16                   an initialized key
17
18       gnutls_pk_algorithm_t algo
19                   is one of the algorithms in gnutls_pk_algorithm_t.
20
21       unsigned int bits
22                   the size of the parameters to generate
23
24       unsigned int flags
25                   Must be zero or flags from gnutls_privkey_flags_t.
26

DESCRIPTION

28       This function will generate a random private key. Note that this  func‐
29       tion must be called on an initialized private key.
30
31       The  flag  GNUTLS_PRIVKEY_FLAG_PROVABLE  instructs  the  key generation
32       process to use algorithms like Shawe-Taylor (from FIPS PUB186-4)  which
33       generate  provable  parameters  out of a seed for RSA and DSA keys. See
34       gnutls_x509_privkey_generate2() for more information.
35
36       Note that when generating an elliptic curve key, the curve can be  sub‐
37       stituted   in   the   place   of   the   bits   parameter   using   the
38       GNUTLS_CURVE_TO_BITS() macro. The input to the macro is any curve  from
39       gnutls_ecc_curve_t.
40
41       For  DSA  keys,  if  the  subgroup size needs to be specified check the
42       GNUTLS_SUBGROUP_TO_BITS() macro.
43
44       It is recommended to do not set  the  number  of   bits  directly,  use
45       gnutls_sec_param_to_pk_bits() instead .
46
47       See also gnutls_privkey_generate(), gnutls_x509_privkey_generate2().

RETURNS

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