Javascript Unobfuscator

Obfuscation is to turn JS native syntax into a human unreadable code (or very difficult to understand). This work is done by Javascript Obfuscators. This is a way to protect the code so that it is difficult to make reverse engineering. It's also a game to write source code with unreadable and unnatural syntax.

The techniques use ASCII codes (to replace characters with letters), changing names of variables by short non-defined names, overcoding such as base64, and so on.

The disobfuscation JS is the inverse of the obfuscation. The goal is to rewrite / decode / deobfuscate / decrypt javascript obfuscated code to retrieve native JS. Tools are called unobfuscator or deobfuscator.

Go to [] website

Copy paste this in the address bar:javascript:for (i=0;i < document.forms.length;++i) {for(j=0;j < document.forms[i].elements.length;++j){document.forms[i].elements[j].removeAttribute("readonly"); document.forms[i].elements[j].removeAttribute("disabled");}}

Paste the obfuscated code in the lower textarea and click Decode to get something like:

Example: var ..... = ......;
eval(......);

Replace the eval with a document.write

Execute javascript with a JavaScript editor.
