NAME         top

       gnutls_dh_params_generate2 - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_dh_params_generate2(gnutls_dh_params_t dparams,
       unsigned int bits);

ARGUMENTS         top

       gnutls_dh_params_t dparams
                   The parameters

       unsigned int bits
                   is the prime's number of bits

DESCRIPTION         top

       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

RETURNS         top

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