JSObfuscator

  

Features

This extension will obfuscate and minify your JavaScript code to make it more secure.

Note

Once the code gets obfuscated you cannot revert it to it's original state. For best use, use this before deployment of your code.

Commands

JSObfuscator : Obfuscate Current Workspace

This command will go through and obfuscate all the js files in your current Workspace. See settings for options to limit which files will be obfuscated.

JSObfuscator : Obfuscate Current File

This command will obfuscate the file you currently have open. This requires you to have saved this file before obfuscating it. This command will also ignore the settings Ignore Min Files and Files To Ignore

Note

By default code pages will be saved as a new file with their extension changed to .min.js and by default existing files will not be overwriten.

Usage

Press Ctrl+Shift+P and search for JSObfuscator: Obfuscate Current Workspace to obfuscate your current Workspace recursively or search for JSObfuscator: Obfuscate Current File to obfuscate the current file. You have to have saved the current file before you can obfuscate it.

Settings

Change File Extension

Default: obfuscated.js
Description: Save the file with a new extension after obfuscating. For example if you put obfuscated.js the file would be changed from test.js to test.obfuscated.js. But, if you try to obfuscating test.obfuscated.js this file will be skipped.

Files To Ignore

Default:
Description: Enter comma separated list of file names to be ignored

Ignore Min Files

Default: true
Description: When processing the Workspace to obfuscate all js files do you want to ignore files with the extension .min.js NOTE: This option is ignored when processing a single file.

Overwrite Existing Files

Default: false
Description: When saving the obfuscated file if a file of the same name exists overwrite it with the obfuscated file.

Sub Path In Workspace

Default:
Description: Specified some relative path where you only want to Obfuscate JavaScript.

        },
        "overwriteExistingFiles" : false,
        "subPathInWorkspace": ""
    } 
}

⚠ Important

Only obfuscate code that belongs to you

It is not recommended to obfuscate vendor scripts and polyfills, since the obfuscated code is 15-80% slower (depending on options) and the files are significantly larger.

Dependencies

This extension use JavaScript obfuscator

jsobfuscator's Issues

Module import doesn't seem to obfuscate

Hey Guys, please find code below. It obfuscates fine unless I comment out the module import statement. That line doesn't seem to obfuscate. Thanks for letting me know what the issue is.
Many thanks and great work, love the tool!

export default class Test {
    myMethod() {
        (async () => {
            //The below line fails to obfuscate. If you comment it out, the file obfuscates fine.
            const myModule = await import('some path to a JS module');
        })();   
    }
}

Update javascript-obfuscator from 2.9.4 to 4.0.2.

Please, update your javascript-obfuscator from 2.9.4 to 4.0.2.
I had errors in the output file. Fixed after editing the version in the extension.
Thanks.

Does not function in VSCode Version: 1.49.2

It just doesn't create any new file, unfortunately. I tried everything possible.

Thanks!

Add option to auto obfuscate to vscode extension

Hay Thanks for nice work.

It would be better if there will be the option to auto obfuscate to .min.js or any other specific sub extension while saving the JS file in vscode extension.

In this way fresh copy of code will be automatically secured and .min.js will be created when we save the .js file same like js minification system.

Regards.

Error whilst objuscating in Visual Studio using v1.3.2

class a {
	func1 = function(e) {
	}
}

gives me:
ERROR at line 2: Unexpected token (2:7)

...func1 = function(e) {...

Can you help me solve please?

Nothing happens

I installed the extension in VSCode and nothing happens when I have a js file open and click to obfuscate the current file.
I also installed Javascript Obfuscator through npm, restarted VSCode, and still nothing happens. This is on Ubunto 20.04.

Error

installed it into VS Code and just tried running it didn't change anything yet and I get this
any idea why?

Also when I run current work place I get this

Internet links text no being obfuscated in Visual Studio Code.

I started to use this extension for VS Code because I already know the online one at https://obfuscator.io.
I am experimenting one problem, when there are some http links in js file, because the obfuscated code stil retain the string of the http links.

for example, if I have this:

["TEST", "https://test.com/levelone/index.html", "images/channel.png", "0"]

The https://test.com/levelone/index.html will not be obfuscated.
I tried the same files at the address of the original obfuscator and it works fine, obfuscating even these addresses.
I opied the configuration parameters at that site (for the Options Preset High), but still not working.

My VSCode configuration is:

Cannot read property 'appendLine' of undefined:

I'm trying to obfuscate a javascript file, es6 but nothing happens and that is the log

[2021-03-24 10:46:52.858] [renderer1] [error] Cannot read property 'appendLine' of undefined: TypeError: Cannot read property 'appendLine' of undefined at /home/xxxx/.vscode/extensions/softheroes.jsobfuscator-1.3.2/extension.js:102:32 at fs.js:1347:7 at FSReqCallback.oncomplete (fs.js:160:23)

i installed extension on Linux from Flatpak

Extension didnt want to run. Problem was that outName = filePathOnly + '\\' + fileName was building invalid path begining with \/..... so i changed code a little bit to check if two begining characters of path are \/ and deleting first char if its true:

outName = filePathOnly + '\\' + fileName
if (outName.charAt(0) === "\\" && outName.charAt(1) === "\/") {
outName = outName.substring(1);
}

Now extension is working and i think it will work on Windows too. Just inform U about issue and how i resolved it simple. I made a fork and pull request. Test it on windows if that works...

Can't obfuscate file with static member

Can't obfuscate file with static member.
Like this

class Test {
static instance = null;
get getInstance() {
if (Test.insatnce == null) {
Test.instance = new Test();
}
return Test.instance;
}
constructor() { }
}

The line

static instance = null;

Stop the obfuscate process
