title: Find base64 in source code with python regex
body: <p>I want to find any base64 code / hash in the website source code. It can be in a JavaScript function call.</p>
  
  <p>Example: </p>
  
  <pre><code>&lt;script type="text/javascript"&gt;data = get_data('aGVsbG8gd29ybGQ=') ); &lt;/script&gt;
  </code></pre>
  
  <p>or in variables.</p>
  
  <p>Is there a reliable way to check this with regex?</p>
