Obfuscator is a tool to modify x86 assembler source code in this way to make an analysis of compiled code very difficult.

It is an unusual tool and the target audience is quite small, but if you're writing assembler code and you want to protect your work from decompilation or just to make it as hard as it's possible to analyze, you might want to try it.

An obfuscator can obfuscate .NET IL Code and protect .NET dll/exe assembly. Obfuscated code is unreadable and unmodifiable, it may anti-decompile and cause decompiler crashed (e.g. .NET Reflector). Obfuscator.NET supports name obfuscation (e.g. class/method/field/parameters etc.) and flow obfuscation. Decompiler can not show correct structure and code of the obfuscated assembly.

Stop theft of your JavaScripts! 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.

.Net Decompiler that decompiles /disassembles .Net assemblies from MSIL (MS Intermediate Language) binary format to well-formed and optimized source code (6 languages: MSIL, C#, VB.NET, Delphi.Net J# and managed C++).

Professional approach to protecting, research, document and reverse engineering .Net assemblies!

It is a shrinker/obfuscator for JavaScripts. You can use it to easily and quickly reduce the size of typical JavaScript files by 50% on average depending on the style the code is written in. Strong JS allows you to delete all unnecessary bytes in scripts, such as comments, new line characters and unnecessary spaces. The execution of the js file won't change after it is compressed. Also, it can rename variables giving them short names.

DashO Java Obfuscator:

* Improves run-time performance--removes unneeded program elements and renames identifiers to small names.

Jasob JavaScript Obfuscator is the ultimate solution for JavaScript obfuscation! Protects your JavaScript code from stealing, significantly shrinks size and improves download time and execution speed. With Jasob your JavaScript code will become impossible to understand thus preventing anyone to steal and modify it. Its size will typically shrink for around 70% which will significantly improve download time and execution speed in the web browser.

{smartassembly} is a .NET software Improvement & Protection tool. It will obfuscate and protect your .NET software, optimize your .NET assembly for better deployment, minimize distribution size, increase performance & add powerful post-deployment debugging capabilities (with advanced unhandled exception reporting). {smartassembly} efficiently enables you to deliver a smart version of your .NET assembly, in no time and with unmatched ease.

Dotfuscator .NET Obfuscator:
* Enhances source code security--state-of-the-art technology protects .NET applications, securing important intellectual property.
* Decreases .NET program size--analyzes applications and figures out which parts are being used (down to the method level). Unused pieces are parsed out, leaving the smallest executable possible.
* Improves run-time performance--removes unneeded program elements and renames identifiers

Scripts Encryptor is a handy utility to scramble (obfuscate) HTML, JavaScript/JScript, C/C++/MFC code. Unlike many other obfuscators it does not employ JavaScript for encoding, which significantly increases the number of web browsers that are able to open scrambled documents without distortion. Use it to protect your online content from unauthorized copying, reverse engineering and from webbots collecting email addresses and other personal data.

.NET Reactor protects your intellectual property by mixing any pure .NET Assembly (written in C#, VB.NET, Delphi.NET, J#, MSIL...) with conventional native code. In detail, .NET Reactor builds a native wall between potential hackers and your .NET code. The result is a standard Windows based(non MSIL compatible) file. The original .NET code remains intact, well protected by native code and invisible for prying eyes.
