NAME

6       gnutls_dh_get_prime_bits - return the bits used in DH authentication
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int gnutls_dh_get_prime_bits(gnutls_session_t session);
12

ARGUMENTS

14       gnutls_session_t session
15                   is a gnutls session
16

DESCRIPTION

18       This  function  will  return  the  bits  of  the prime used in the last
19       Diffie-Hellman authentication with the peer.  Should be used  for  both
20       anonymous  and  ephemeral Diffie-Hellman.  Note that some ciphers, like
21       RSA and DSA without DHE, does not use a  Diffie-Hellman  exchange,  and
22       then this function will return 0.
23

RETURNS

25       The  Diffie-Hellman bit strength is returned, or 0 if no Diffie-Hellman
26       exchange was done, or a negative error code on failure.
