Online tools to encrypt your Javascript code on the fly

Javascript Obfuscated code is regular non-compressed code that has been made difficult to understand via various types of encryption. In most cases programmers intentionally obfuscate code to obscure its functionality, functions and coding techniques. The obvious reason for this is protect the code from reverse engineering; essentially assuring it cannot be copied/reused by other programmers. This method of protecting the code is known as Obfuscation. Obfuscation transforms human-readable code into what appears as a random assortment of characters. Obfuscation can be achieved using various techniques. And although the before and after code look nothing alike, they will still function the same.

Obfuscating code to prevent reverse engineering is in general done to avoid risks that are associated with unauthorized access to source code. With most server side code like PHP and ASP the code is protected from unauthorized access because it resides on the server that only you have access to. However client side code such as Javascript and VBScript do not have that luxury. Since the client side code is downloaded and executed by the browser, users are able to see its source code. Thus that is why Obfuscating code is usually done just to client side scripts.
