Scramble, obfuscate, and pack JavaScript code!
Javascript Obfuscator converts the JavaScript source code into
scrambled and completely unreadable form, preventing it from analysing and theft.
Javascript Obfuscator can
- process javascript tags in html files and all .js files associated with html pages as well as separate .js files
- remove comments and white spaces, reducing the file size and
minimizing the loading time
- pack the code as a long line
- add finishing ";" when appropriate
- create a list of function and variable names
- generate new non-understandable names and rename functions and
variables depending on user settings
- work with command line
Compare how the same piece of code looks before:
//detect which browser is used
var detect = navigator.userAgent.toLowerCase();
var OS,browser,version,total,thestring;
if (checkIt('konqueror'))
{
browser = "Konqueror";
OS = "Linux";
}
else if (checkIt('opera')) browser = "Opera"
else if (checkIt('msie')) browser = "Internet Explorer"
else if (!checkIt('compatible'))
{
browser = "Netscape Navigator"
version = detect.charAt(8);
}
else browser = "An unknown browser";
//version of browser
if (!version) version = detect.charAt(place + thestring.length);
//client OS
if (!OS)
{
if (checkIt('linux')) OS = "Linux";
else if (checkIt('x11')) OS = "Unix";
else if (checkIt('mac')) OS = "Mac"
else if (checkIt('win')) OS = "Windows"
else OS = "an unknown operating system";
}
//check the string
function checkIt(string)
{
place = detect.indexOf(string) + 1;
thestring = string;
return place;
}and after processing by Javascript Obfuscator:
var
e=navigator.userAgent.toLowerCase();var
f,b,c,total,d;if(a('konqueror')){b="Konqueror";f="Linux";};else
if(a('opera'))b="Opera";else if(a('msie'))b="Internet Explorer";else
if(!a('compatible')){b="Netscape Navigator";c=e.charAt(8);};else b="An
unknown
browser";if(!c)c=e.charAt(g+d.length);if(!f){if(a('linux'))f="Linux";else
if(a('x11'))f="Unix";else if(a('mac'))f="Mac";else
if(a('win'))f="Windows";else f="an unknown operating system";};function
a(string){g=e.indexOf(string)+1;d=string;return g;};
You can see the difference, can’t you?
