Have you had experience using the Charles tool for network traffic analysis?

Yes, the Charles Proxy tool is often used for analyzing network traffic, especially when testing web and mobile applications. It allows:

• Intercepting and viewing HTTP/HTTPS requests and responses.
• Modifying requests on the fly to test server behavior.
• Monitoring performance and response times.
• Repeating requests for regression testing.

For example, with Charles, you can check what data the application sends during authorization and ensure that passwords are not transmitted in plain text.
