php – How to secure traffic between iOS-app and server?

Posted by: admin July 12, 2020 Leave a comment

Questions:

I am building an app which gets JSON-encoded data from a web server. Right now, anyone can access the server-script that gets the data, and potentially access sensitive data.

So, what is the best way to ensure that the app is what’s getting the data, and secure the traffic between the server and app?
The server-script is PHP.

Thank you.

In general, you can’t. The best you can do is use some sort of login system, but anyone sniffing packets will be able to figure that out.

and secure the traffic between the server and app?

Use TLS, i.e., HTTPS using SSL.
