title: Encrypt HTML Source code with JAVASCRIPT. How does it work?
body: <p>i was checking if it is possible to actually encrypt html code or not. I found a place where they encrypt the HTML code in Javascript. 
  I wonder how does it work or in what format can anyone please tell me ??</p>
  
  <p>Actual code</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;body&gt;
  
  &lt;p&gt;This is going to be encrypted.&lt;/p&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The encrypted HTML CODE</p>
  
  <pre><code>  &lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;script type="text/javascript"&gt;
