Javascript Obfuscator

[Costas]

An application that applies string, method calls, function and variable obfuscation on javascript, JQuery enabled.

You still obfuscating like year 2000, using the eval() function? Or the nasty obfuscators around that have nothing to prove just rename the variable/function names then afterwards someone can easily read it using the famous http://jsbeautifier.org/ No way!



The application uses special text search functionality, doesnt know anything about javascript!

application rule :

//dont use variable declaration with const ex.
var x = 3;

//should be

var x;
x=3;

v1.2 [27/11/2013]
+now obfuscate functions names
+array call is 'more secure' using poly engine!
*bug - when in #if condition# using a property equal with arithmetic example #if (word.length==0)# (aka line 44 on source)
-bug discover - when is a reference to an array ex. #items[2]# encrypts also the brackets should be fixed

v1.1 [24/11/2013]
+now obfuscate variables!
+trim single line comments
+export all code to one line
