Using TLS, you can be sure that the server to which you are connected is Amazon’s, that no one sees the contents of your order, and that Amazon can verify that the order they received is the one that you sent. This article uses code examples to show how Apple’s mobile operating system, iOS, supports TLS and what you need to do to add it to your iPhone/iPad application.
