gnutls_dh_params_generate2(3)	    gnutls	 gnutls_dh_params_generate2(3)

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 parame-
       ters 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 er-
       ror code	is returned.
