title: Securing a REST API and Slim Framework
body: <p>I am fairly new to REST APIs, and I realize there are quite a few questions already posted. However, perusing these has actually left me more confused on how to handle this.</p>
  
  <p>I have created a REST API using <a href="http://www.slimframework.com/">Slim Framework</a> which I am simply using to transfer data. I won't be using user logins or authentication, so I believe to secure this I just need a system that using a public key and a private key, but I am just not sure.</p>
  
  <p>If anyone has insight on the correct / most secure way to do this, or any tutorials / resources that would be great. Any help is appreciated.</p>
