title: How I can programatically get the chrome extension ID from a crx file?
body: <p>I compile the extension using the <code>--pack-extension</code> switch:</p>
  
  <pre><code>C:\Users\APOL0\AppData\Local\Google\Chrome\Application&gt;chrome.exe --pack-extension="D:\MyExt"
  </code></pre>
  
  <p>Everything works fine: chrome generates <code>Myext.crx</code> and <code>Myext.pem</code> but I don't know how I can get extension ID for automatic installation using Windows' registry. </p>
  
  <p>How can I get this ID without using "manual verification", ie. programatically?</p>
