On the contrary, the clearly characterized TLS protocol (TLS/SSL) is used to make the flow look the same as the normal HTTPS website. TLS is a mature encryption system, and HTTPS uses TLS to carry HTTP traffic. For passive testing, the flow of the Trojan agreement is completely consistent with the characteristics and behavior of the HTTPS flow. ...
