title: Spring Boot TLS
body: <p>I am using a spring boot 2.0.2 app to make REST api calls to an external api via HTTPS.</p>
  
  <p>I am new to the world of TLS and SSL. My understanding is TLS is the more secure way of communicating secure sensitive data.</p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>How do I determine what version of TLS my app is using ? </li>
  <li>As a consumer of an API what should I do to ensure I am communicating using a particular version of TLS ?</li>
  <li>Is TLS a client side thing or a server side thing or is it both ?</li>
  </ol>
