Имя (Name)
gnutls_dh_params_generate2 - API function
Синопсис (Synopsis)
#include <gnutls/gnutls.h>
int gnutls_dh_params_generate2(gnutls_dh_params_t dparams,
unsigned int bits);
Аргументы (Arguments)
gnutls_dh_params_t dparams
The parameters
unsigned int bits
is the prime's number of bits
Описание (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.
Возвращаемое значение (Return value)
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error code is returned.
