NAME

       gnutls_privkey_generate - API function

SYNOPSIS

       #include <gnutls/abstract.h>

       int  gnutls_privkey_generate(gnutls_privkey_t  pkey,  gnutls_pk_algorithm_t algo, unsigned
       int bits, unsigned int flags);

ARGUMENTS

       gnutls_privkey_t pkey
                   An initialized private 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  empty  private  key.  The  flag  GNUTLS_PRIVKEY_FLAG_PROVABLE  instructs  the  key
       generation process to use algorithms which generate provable parameters out of a seed.

       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 .

RETURNS

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

SINCE
