That is why these systems generate their own certificate that you add to your phone, so you still can see the traffic. For MITMProxy you can visit http://mimt.

That is why these systems generate their own certificate that you add to your phone, so you still can see the traffic. For MITMProxy you can visit http://mimt.it http://mimt.it when the setup is running. A bit more difficult with “pinned-setificate” where you have to: 1) Decompile the app (easy if you search for the online APK-download and APK-decompile tools) 2) Move the certificate out of the APK and use it for the traffic between MITMProxy/Charles and the server 3) Replace the certificate in the APK with one generated for MITMProxy/Charles, or just delete it if that works for the app (most likely not) 4) Re-compile the APK and install on your device 5) Run MITMProxy/Charles as before, just with some parameters to load the “pinned-certificate” (There is also a lot of guides for this. Maybe not for pinned-certificate.)
