NAME

       gnutls_x509_privkey_generate2 - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_privkey_generate2(gnutls_x509_privkey_t  key, gnutls_pk_algorithm_t algo,
       unsigned int bits, unsigned  int  flags,  const  gnutls_keygen_data_st  *  data,  unsigned
       data_size);

ARGUMENTS

       gnutls_x509_privkey_t key
                   a key

       gnutls_pk_algorithm_t algo
                   is one of the algorithms in gnutls_pk_algorithm_t.

       unsigned int bits
                   the size of the modulus

       unsigned int flags
                   Must be zero or flags from gnutls_privkey_flags_t.

       const gnutls_keygen_data_st * data
                   Allow specifying gnutls_keygen_data_st types such as the seed to be used.

       unsigned data_size
                   The number of  data available.

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.

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

       Do not set the number of bits directly, use gnutls_sec_param_to_pk_bits().

RETURNS

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