Jasob.com Releases New JavaScript Obfuscator – Jasob 1.8

Why it’s good to obfuscate your JavaScript source code?

There are two good reasons. First, you will stop theft of your JavaScript source code. And second, its size will shrink for around 70% which will significantly improve download time and execution speed in the web browser.

What is obfuscation anyway?

The obfuscation is a process of replacing long descriptive function and variable names like Customer, Salary, FirstName… with short meaningless names like d, g, m…. Comments and unnecessary whitespace characters are also removed. The functionality of the JavaScript code remains the same while source code changes dramatically. Obfuscated code is impossible to reverse-engineer and extremely hard or impossible to understand. It is better to distribute obfuscated version of your JavaScript code and to keep your original JavaScript source code for yourself.

Jasob 1.8 Features

* Jasob is capable of reading JavaScript code from the following file types: JavaScript Files, HTML Files, XHTML Files, ASP Files, ASP.NET Files, PHP Files, JSP Files, XML Files, Cold Fusion Files and ePerl Files.
* Rules for JavaScript code blocks for various sources (file types) can be customized.
* JavaScript names that can’t be changed in the process of obfuscation can be customized.
* When opening files, Jasob can open a single file, multiple files, the Jasob project or the whole web site.
* There is the file viewer that shows the selected file’s contents. Depending on the currently selected tab at the top of the file viewer, source or obfuscated file’s contents is displayed. Syntax highlighting is applied to the file’s contents to make it more readable. Syntax highlighting colors can be customized. You can find text, go to the specified line and character number or use bookmarks. Also, you can easily highlight selected name(s) occurrences in the file viewer and navigate to those occurrences. Navigating from name occurrence in the source file’s contents to the same name occurrence in the obfuscated file’s contents and vice versa is also possible.
* The names bag provides support for working with a smaller subset of arbitrary names. You can apply changes from names in the names bag to names in name lists, or update names in the names bag with data from names in name lists. You can also add comments to the names bag, open it, or save it to the file.
* Great support for names that appear in strings.
* Great support for dynamic web pages.
* An optional command-line interface enables you to automate the JavaScript obfuscation.
* Complete, illustrated, on-line User’s Guide with examples.
