My question is about this image. Suppose that client is Alice and Server is Bob.
So, basically, I'm trying to setup a scenario... I have a remote Server (Bob) that has an https website. I make:
openssl s_client -connect host:443 -status -CApath /etc/ssl/certs/ -CAfile /etc/ssl/certs/ca-certificates.crt that gives me the response about the OCSP. The wireshark only shows packets between me and server... There are not a CA or another thing.
What am I doing wrong or what I am not understanding? Is the CA the OCSP responder? How do I get the answer?
If I'm not doing well, what do I have to change in my setup?
