This is not the same as transport, yes?

No matter how indirectly, the user installs a (root) CA causing trust or allowed someone else to do so.Generally speaking, yes. I just mean, that in some other protocols you have no any possibility to make MiTM by any way, whenever installing something or not. This prevents any improper or malicious use of protocol. TLS*have* this possibility. SSH is *not*. You can't MiTM or compromise SSH by installing any key/certs to client. Correct? This is by design?No. SSH is just TCP/telnet over TLS. So if the SSH software were to trust the cert/key Squid delivers one could use SSL-Bump on that SSH traffic.You sure? https://stackoverflow.com/questions/723152/difference-between-ssh-and-ssl-especially-in-terms-of-sftp-vs-ftp-over-ssl Quote: "SSH has its own transport protocol independent from SSL, so that means SSH DOES NOT use SSL under the hood." Because I'm not. Different sources tells opposite.I'm sure SSH using openssl under the hood. But not sure it uses same tunneling implementation like TLS-over-HTTP. And now it is still unknown any method to MiTM SSH, AFAIK.I'm not 100% sure, but it uses the same message framing as TLS and performs the same handshake sequence and security verifications. It seems to me that the difference is not of principle. Both SSL and TLS use the same architecture, in which, in principle, it is possible to have an MiTM certificate, which one of the parties trusts.That said *SSL* _is_ different from TLS so the quote is technically correct either way.
