Charles proxy internet connection still encrypted

Question

I'm trying to use Charles with my phone but it just doesn't work. I tried with 2 differents phone, an iOS and an android and none of them are working..

Here is the step I followed for iOS : (I found them here)

1 - Help > SSL Proxying > Install Charles Root Certificate on a mobile device

2 - On the iPhone, Settings > Wi-Fi > my network > Configure Proxy > Manual And I wrote the IP address and Port that I just got with Charles

3 - I accept the message on Charles that said "a new device is attempting to connect"

4 - Then, on the iPhone, Settings > General > Profiles, I install the Charles Proxy CA

5 - Then, still on the iPhone, Settings > General > About > Certificates, I enable the root certificate

6 - It's supposed to be ready, so I make a test on google and all the contents are still encrypted..

If anyone know how to solve it, I'm listening :)

Answer 1

There are various reasons why you could not intercept the HTTPS Content:

• Your app is using SSL-Pinning, which prevents MiTM apps like Charles Proxy or Proxyman intercepts the HTTPS Traffic. => If it's, there is no way to achive it, unless you have the pinned certificate

• It seems that you tried to see the HTTPS content from google.com, but it doesn't work => Look like one of the steps is missing. Please double-check again.

• If you're testing on Android devices, please make sure you add some config to network_security_config.xml file. Read more at https://docs.proxyman.io/debug-devices/android-device#android-setup-guide

Solution:

• Follow the troubleshooting page to find out where the problem is:

• You might try Proxyman - which has a built-in comprehensive guide to help you intercept HTTPS traffic from iOS or Android Device

• If it's too complicated, you can try the automatic script for Android Emulators (Auto set HTTP Proxy, Install and Trust the certificate)

Disclaimer: I write Proxyman, and hope it helps you.
