title: Dynamic JavaScript Obfuscation
body: <p>I've developed a system that polls a server and injects the response JavaScript into the clients web page. I want to obfuscate the JavaScript the server serves, but I also want to know if there is a tool that dynamically obfuscates it according to a token or key. Meaning every new session gets unique scripts that will only work with that client during that session.</p>
  
  <p>If this doesn't already exist, could someone maybe provide me with a link on how to write my own JavaScript obfuscation tool.</p>
