gnutls_dh_params_generate2(3) - Linux man page

Name

gnutls_dh_params_generate2 - generate new DH parameters

Synopsis

#include <gnutls/gnutls.h>

int gnutls_dh_params_generate2(gnutls_dh_params_t params, unsigned int bits);

Arguments

gnutls_dh_params_t params: Is the structure that the DH parameters will be stored
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. The new parameters will be allocated using gnutls_malloc() and will be stored in the appropriate datum. This function is normally slow.

Note that the bits value should be one of 768, 1024, 2048, 3072 or 4096. 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.

Returns

On success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned.
