title: HTML text obfuscator
body: <p>In my view I have some field that I want to obfuscate. They are simple text (e.g. price).
  I am looking for a library in Ruby (or Rails) that allows me to obfuscate HTML text.</p>
  
  <p>E.g.:</p>
  
  <pre><code>&lt;%= obfuscate("4.99") %&gt;
  </code></pre>
  
  <p>and produces some javascript (or unintelligible HTML), something like <a href="http://hivelogic.com/enkoder/" rel="nofollow">http://hivelogic.com/enkoder/</a></p>
  
  <p>thanks,</p>
