Interactive obfuscation of files of various types

Use controls at the right to see how different options affect result of obfuscation; use player-like buttons to navigate between samples and to control playback.

Obfuscate and encode ASP with our VBScript Obfuscator and VBScript Encoder. It protects VBScript in ASP or html files by obfuscating and encoding it. Obfuscation and encoding of vbscript and asp can be controled by a lot of options. Obfuscated and encoded VBScript or asp pages run on any VBScript-compatible interpreter. Our ASP Obfuscator mangles vbscript and asp in all files in the project. Mangling and scrambling of vbscript is controlled via commandline or GUI very precisely.


Unique features of VBScript Obfuscator
Protects VBScript in HTML, PHP ASP.NET, JSP files too

You can protect VBScript in .vbs files, as well as in HTML, PHP, ASP.NET, JSP, WSH/WSC files too.

HTML Markup can also be mangled

VBScript Obfuscator can also make HTML markup less readable, by removing whitespaces, lines and comments, encoding some characters as character escapes, and uglifying tag names and attribute names.

Protect dynamic VBScript

Protect VBScript code contained in print()-like calls in the lines written in other language like PHP, Ruby, Java or even C++.

Code is protected on your computer, not in cloud

Your code is protected locally on your computer. No internet connection is required for protecting your code by VBScript Obfuscator.

Make your code expiring

Bind your code to certain domain or server name, allow it to run until certain date or even only on Fridays. Implement your own licensing condition checks and actions if they are violated.

Watermark your code

Make different versions of your code and ship each of them to different customer. This will allow you to find out which customer distributed your code without your permission.

Features of GUI for VBScript Obfuscator
Full support for multifile projects, with files of different types

You can create projects containing files of several types (e.g. .html, .php and .js files in a single projects), all symbols will be consistently renamed in all files.

Has GUI and command line versions

Stunnix JavaScript Obfuscator has powerfull GUI shell called Project Manager. It can generate command line scripts to build/rebuild/clean entire or part of your project. Also low-level command line interface is available.

Supports Windows, Mac and Linux

GUI and commandline versions of VBScript Obfuscator can be run on Windows, Mac and Linux.

Debugging mode included

Among dozens presets, there are 3 presets for debugging your code. They help preparing your code for protection by applying the protection gradually, that makes testing your code easier.

Extremely configurable

A lot of options to tightly control obfuscation and checks for licensing conditions are available - each function has a lot of options. For example, there are 5 ways to mangle symbols (names of functions and variables).

String inspector available

You can generate a list of strings found in your project that look like containing VBScript code. If they really contain it, you will have to wrap those strings into calls of special functions, so symbols in those strings also become mangled.

The obfuscation of raw VBScript code means

Click on the small button "more info" below each item to expand details.

Replacing symbol names with non-meaningfull ones, e.g. replacing list_of_customers with zcadaa4fc81
Replacing numeric constants with expressions, e.g. replacing 232 with (&hd99+5451-&h21fc)
Removing or obfuscation of comments
Removing spaces and tabs in the lines of code
Joining all lines in your code
Encoding the result of previous stages

Besides obfuscation of raw VBScript code mentioned above, the following extra protection is applied to web documents

Click on the small button "more info" below each item to expand details.

All VBScript code inside <SCRIPT> tags is obfuscated
Code inside attributes (e.g. onclick) is obfuscated
HTML comments are removed from the output (but server-side markup like SSI is not)
Extra spaces and line breaks are removed intelligently
The content of documents and the content of attribute values are partially converted into entities in a random way
The case of letters in tag and attribute names is randomly mixed

The features summary of VBScript Obfuscator

Click on the small button "more info" below each item to expand details.

It extracts all string constants found in your code, and lets browse all of them, or those equal to symbol used in your project (most probably they are property name), or those containing some symbol used in your project (probably used in eval()-like calls), or those looking like symbol. This allows to quickly compose list of "exceptions" - names of symbols that should not be modified.
