NAME
       gnutls_dh_params_generate2 - API function


SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_dh_params_generate2(gnutls_dh_params_t dparams, unsigned int bits);


ARGUMENTS
       gnutls_dh_params_t dparams
                   The parameters

       unsigned int bits
                   is the prime's number of bits


DESCRIPTION
       This function will generate a new pair of prime and generator for use in the Diffie-Hellman key exchange.
       This may take long time.

       It  is recommended not to set the number of bits directly, but use gnutls_sec_param_to_pk_bits() instead.
       Also note that the DH parameters are only useful to servers.  Since clients use the  parameters  sent  by
       the server, it's of no use to call this in client side.

       The  parameters  generated  are  of  the  DSA  form.  It also is possible to generate provable parameters
       (following the Shawe-Taylor algorithm), using gnutls_x509_privkey_generate2() with  DSA  option  and  the
       GNUTLS_PRIVKEY_FLAG_PROVABLE flag set. These can the be imported with gnutls_dh_params_import_dsa().

       It  is  no  longer  recommended  for applications to generate parameters.  See the "Parameter generation"
       section in the manual.


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