Stunnix JavaScript Obfuscator is a unique solution for this piracy and misuse problem for code written in ECMAScript or JavaScript programming languages. It's both an obfuscation and encoding tool for JavaScript source code in .js files and in HTML, PHP, ASP and JSP pages, with advanced support for adding difficult to remove Automatic licensing checks. JavaScript Obfuscator converts Scripts from input files into a highly mangled and obfuscated form. This makes them extermely difficult to Study, analyse, reuse and re-work for competitors or customers, while fully retaining the functionality of the original code. By default that highly mangled and obfuscated code is encoded afterwards to hide the structure (control flow, division into subroutines and classes) of the script completely. JavaScript Obfuscator is not a compiler to machine or pseudo code - the protected form will still be the usual script, thus it will work on all platforms the original code worked on. State of the art support for ensuring license conditions (expiration, several types of hostname checks, user-defined checks) is also available. Note, that Stunnix JavaScript Obfuscator is referred to as Stunnix JS-Obfus for brevity in some places on this site.
