Thanks for the help.I couldn't find any flags/fields in TCP packets indicated whether encrypted (as in the case of SSH packets). There isn't any, right?
Correct: there isn't anything like that in the TCP headers. Encryption on TCP streams is an application level thing that only affects packet payloads. There are transport layer encryption protocols -- eg. IPSec, OpenVPN, etc. -- but those allow tunnelling TCP streams through them and aren't necessarily TCP themselves.
