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 anonymous and  ephemeral  Diffie-Hellman.
       Note  that  some  ciphers, like RSA and DSA without DHE, does 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.
