title: Encrypting/Decrypting a POST form
body: <p>I'm really new to php so what's happening is that I have a form which has an action of 'email_form.php'.  CLicking the submit button takes the user to 'email_form.php' which processes the information (it looks something like below);</p>
  
  <pre><code>&lt;?php
  $to = "email";
  
  $subject = "rego form";
  
  $ message = "Name: " . $_REQUIRE['Title'] . "\r\n" .
  
  .
  .
  .
  
  RE['CancellationPolicyAgreement'];
  
  $from = $_REQUIRE['Email'];
  
  $headers = "From: $from" . "\r\n";
  
  $headers = "Bcc: email" . "\r\n";
  
  mail($to,$subject,$message,$headers);
  
  ?&gt;
  </code></pre>
  
  <p>`</p>
  
  <p>Something like that.  So my question is - how do I encrypt the form content?  Obviously I've cut out some fields, but it does include credit card details and that's not something I'd want anybody else to get.</p>
  
  <p>If anybody could give me a simple, layman-term explanation that would be really REALLY appreciated!!!!</p>
