Ask HN: What all content can a MitM proxy/app decrypt from the HTTPS traffic?

1 points by m33k44 ↗ HN
If I install something like Wireshark, Fiddler or mitmproxy, will I be able to decrypt all HTTPS content flowing from my computer to the application server of interest? If yes, then how to secure web traffic against such activity?

Yes.

By uninstalling Wireshark, Fiddler or mitmproxy.

Well, I was interested in preventing others from sniffing the traffic. If I am the app owner or an app user, then anyone on the LAN or shared home network can sniff the traffic.

Unless you let others access your mitmproxy setup, then you do not need to worry.
