This book seems to be interesting, but I am student and I have to save money... Yes I know that DH is subject to a MITM attack. I make DH key exchange in a secure channel with authenticated peer. How to serialized dh->pub_key ? I know that i2d_DHparams(const_dh, &dhbuf); serialize dh structure pointed by const_dh but I did not find a function to serialize just dh->pub_key ikuzar.
