gnutls_dh_get_prime_bits(3) gnutls gnutls_dh_get_prime_bits(3) NAME
gnutls_dh_get_prime_bits - return the bits used in DH authentication 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 authentication with the peer. Should be used for both anonymous and ephemeral Diffie-Hellman. Note that some ciphers, like RSA and DSA without DHE, does not use a Diffie-Hellman exchange, and then this function will return 0. RETURNS
The Diffie-Hellman bit strength is returned, or 0 if no Diffie-Hellman exchange was done, or a negative error code on failure. REPORTING BUGS
