NAME
gnutls_dh_get_prime_bits - API function
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_dh_get_prime_bits(gnutls_session_t session);
ARGUMENTS
gnutls_session_t session
is a gnutls session
DESCRIPTION
This function will return the bits of the prime used in the last Diffie-Hellman key exchange with the peer. Should be used for both anony-
mous and ephemeral Diffie-Hellman. Note that some ciphers, like RSA and DSA without DHE, do not use a Diffie-Hellman key exchange, and
then this function will return 0.
RETURNS
The Diffie-Hellman bit strength is returned, or 0 if no Diffie-Hellman key exchange was done, or a negative error code on failure.
