  1. First right click on the URL you want to decrypt to enable SSL Proxying Enable proxy

  2. Go to Proxy -> SSL Proxying Setting -> Check if Enable SSL Proxy is enabled and there is the field which you just right-click to enable proxy

  3. Go to Keychain, search for Charles and change the field trust to "Always trust"

  4. Restart your Charles and voila.

If the response text is unreadable, it means that the SSL Proxying doesn't set up properly. Check the following steps to fix it:

  1. Help Menu -> SSL Proxying -> Install Charles Root Certificate
  2. Open Keychain and search Charles Proxy
  3. Double Click to open and select Always Trust for all dropdowns.
  4. Back to Charles Proxy -> Right Click on the domain you need to intercept -> Enable SSL Proxying
  5. Enjoy!

If it's too complicated, you can checkout Proxyman, which has a feature to do all steps automatically by going Certificate Menu -> Install Certificate on macOS

Install Certificate

For me no one answer sufficed,

  1. Did this: https://stackoverflow.com/a/42969202/865220

  2. But even after doing that I found for few hosts/urls it was not decrypting, so I had to do this: https://stackoverflow.com/a/49147470/865220

  3. Now my pip install <any package> stopped working because of this, so I had to do this: https://stackoverflow.com/a/49910594/865220

You must intalls a SSL certificate on your device. Be sure that you are connected to Charles proxy and the try to go to the followin url: chls.pro/ssl (if you are using an Android device you can use Chrome and if you are using an iOS device you must use Safari)

You will be able to add the certificate on your computer as well, if you don't do it, you will not be able to use your browser when Charles is working.

Steps in this video helped me to solve this problem https://www.youtube.com/watch?v=_tPvZjHPSC8

Basically you need to download a certificate to your device(simulator). Open safari and go to chls.pro/ssl and install it. Then on the device go to settings->general->about->Certificate Thrust settings and enable the certificate. Then enable SSL proxy in Charles by going to Proxy tab->SSL proxy and voila.

you'll often see what looks like gibberish there because the response hasnt completed. (Note that the connection you highlighted has not completed and is not providing a 200 HTTP Status.) If you select Hex on the bottom of the Charles window, you can view what was completed in Hexadecimal. It can be translated but the text view you are looking at for incomplete calls like that is always going to look like gibberish.

Try to view the call's response again when it is completed.

If you're having trouble getting calls to complete. That is a separate issue. Try the SSL connection and install a certificate like the others commented about. That can be found on Charles toolbar Help>SSL Proxying > Charles Root Certificate Help.
