NAME

       gnutls_x509_privkey_generate - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_privkey_generate(gnutls_x509_privkey_t  key,  gnutls_pk_algorithm_t algo,
       unsigned int bits, unsigned int flags);

ARGUMENTS

       gnutls_x509_privkey_t key
                   an initialized key

       gnutls_pk_algorithm_t algo
                   is one of the algorithms in gnutls_pk_algorithm_t.

       unsigned int bits
                   the size of the parameters to generate

       unsigned int flags
                   Must be zero or flags from gnutls_privkey_flags_t.

DESCRIPTION

       This function will generate a random private key. Note that this function must  be  called
       on an initialized private key.

       The  flag  GNUTLS_PRIVKEY_FLAG_PROVABLE  instructs  the  key  generation  process  to  use
       algorithms like Shawe-Taylor (from FIPS PUB186-4) which generate provable  parameters  out
       of a seed for RSA and DSA keys. See gnutls_x509_privkey_generate2() for more information.

       Note that when generating an elliptic curve key, the curve can be substituted in the place
       of the bits parameter using the GNUTLS_CURVE_TO_BITS() macro. The input to  the  macro  is
       any curve from gnutls_ecc_curve_t.

       For   DSA   keys,   if   the   subgroup   size   needs   to   be   specified   check   the
       GNUTLS_SUBGROUP_TO_BITS() macro.

       It   is   recommended   to   do   not   set   the   number   of    bits   directly,    use
       gnutls_sec_param_to_pk_bits() instead .

       See also gnutls_privkey_generate(), gnutls_x509_privkey_generate2().

RETURNS

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