How to safely use 'curl ignore cert' for testing without compromising security?

I’d avoid curl ignore cert unless you’re absolutely sure about the environment. Even then, it’s risky.

For testing, I use a combination of Postman and ngrok. Ngrok tunnels your local server with HTTPS, so you don’t have to mess with certs.

Also, if you’re testing APIs, consider using a tool like SoapUI. It’s got way more features than curl and handles SSL better.
