title: Securing connection to php server without SSL
body: <p>I have following scenario: The Android clients communicate with a PHP server via HTTP Post. The PHP server is communicating with mySQL database and sends the output as JSON to the Android client.
  I have stated this already in question: <a href="https://stackoverflow.com/questions/8670312/securing-connection-to-php-server">securing connection to php server</a></p>
  
  <p>The conclusion there is to use TLS/SSL to secure the connection. Unfortunatelly my server does not support tls. </p>
  
  <p>Is there some other way to somehow make it little more difficult to get the API of my php server, so people cannot post via PC to my server.</p>
  
  <p>I thought about gzip, but I it will be a low barrier...</p>
  
  <p>So if someone sniffs the traffic with wireshark, he should not easily get how the communication to my php server is done. </p>
