Network traffic encryption

Hello everyone.
I’ve tried to search this one but no luck. So I decided to create this thread. Is there any encryption applied to the network traffic or it’s just a plain text transfer?

It’s just a stream of your bytes, along with any protocol overhead. Have a look with something like WireShark.

Hello and thank you for your answer.
Yes, I know how it looks like. But nevertheless it’s possible to do a man-in-the-middle attack. I thought that there is something like EnableSecurity() from old network solution.
