title: HTTPS on iPhone - What kind of encryption?
body: <p>I'm using an <code>NSMutableURLRequest</code> in an iPhone app, that uses a <code>Content-Type</code>:</p>
  
  <pre><code>application/x-www-form-urlencoded
  </code></pre>
  
  <p>The protocol is <code>https</code>.</p>
  
  <p>From what I understand, this means the app uses encryption. But, what <em>kind</em> of encryption? According to Apple's export compliance page, they need to know whether I use > 64-bit symmetric or > 1024-bit asymmetric algorithms.</p>
  
  <p>I honestly have no idea whether I do or not! Is there any simple answer to this question?</p>
