Using Encrypted PayPal Buttons (EWP) and IPN

If you want to accept PayPal payments on your site you have a variety of options. What I consider to be the ideal solution is a pairing of their IPN service with encrypted buttons. This allows your customers/clients to pay you securely without having to host an SSL cert on your site. Using encrypted buttons we can dynamically generate the amount values without having to worry about them being tampered with. Sure you could always verify the amount later, but why bother when there’s an easily solution around that, plus who really needs the hassle? This guide will walk you step-by-step from the question of “how?” to setting up a sophisticated payment solution.
