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
       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_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_generate2().

RETURNS

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