The characters are unreadable in the http requests and responses captured by Charles

Question

I use Charles on Windows 10 to capture network requests and responses.

But the characters in the requests and responses are unreadable.

How can I make these characters readable?

Answer 1

The problem you are having is that you are trying to read SSL based HTTP requests (this is: https requests).

Roughly what you need to do is enable SSL in Charles. Everything you need you will find it in the SSL Proxy Settings, under the Proxymenu:

1. Install the Charles certificate on your browser
2. Add the domains you want to inspect to the proper SSL Proxy Settings.

This should give you the same screen with all the content you expected to see without any kind of encryption.
