• 2 Please clarify. What are you asking? – Kryten Commented Jan 6, 2010 at 17:46
• 1 Looking at some of your earlier questions, is your main concern is how could someone maliciously distort your javascript into unreadable code? – Anthony Forloney Commented Jan 6, 2010 at 17:48
• 3 I'd be rather more concerned about fixing the exploit that let the Russians promise your site! – bobince Commented Jan 6, 2010 at 17:50

It's called obfuscation. You can find a list of tools in many SO questions. For example:

• How can I obfuscate JavaScript?
• What is the best javascript obfuscator?
• Free JavaScript obfuscators?

What you search for is Obfuscation.

This one works with PHP and pretty good:
http://www.phpclasses/browse/package/1863.html

This is what you want.

var txt = "http";
console.log(btoa(txt));  //gives you "aHR0cA=="
