How to infiltrate a secure channel?

Question

openvpn

Hi all.
Tell me, please, how can I infiltrate the ethernet channel and secure connection (vpn or just ssl), if I have all the necessary keys and certificates for clients and servers. Well, the substitution of traffic right there.

Answer 1

Read about the bumping mode in squid, which actually does just that - crashes into the connection between the client and the server to find out where the client actually went.
