有许多免费的JavaScript混淆工具;然而，我认为重要的是要注意，很难混淆JavaScript到不能进行逆向工程的地步。

为此，我在一定程度上使用了几个选项:

YUI Compressor. Yahoo!'s JavaScript compressor does a good job of condensing the code that will improve its load time. There is a small level of obfuscation that works relatively well. Essentially, Compressor will change function names, remove white space, and modify local variables. This is what I use most often. This is an open-source Java-based tool. JSMin is a tool written by Douglas Crockford that seeks to minify your JavaScript source. In Crockford's own words, "JSMin does not obfuscate, but it does uglify." It's primary goal is to minify the size of your source for faster loading in browsers. Free JavaScript Obfuscator. This is a web-based tool that attempts to obfuscate your code by actually encoding it. I think that the trade-offs of its form of encoding (or obfuscation) could come at the cost of filesize; however, that's a matter of personal preference.

Dean Edward's Packer是一个很好的混淆器，尽管它主要是混淆代码，而不是代码中可能存在的任何字符串元素。

我可以推荐Patrick J. O'Neil的JavaScript Utility。它可以模糊/紧凑和压缩，它似乎很擅长这些。也就是说，我从未尝试将它集成到任何类型的构建脚本中。

至于混淆和缩小，我不太喜欢前者。它使调试不可能(错误在第一行…“等等，只有一行”)，而且他们总是要花时间打开行李。但如果你需要…好。

你绝对应该考虑一下Obfuscriptor。

我超越了我们从其他工具(如YUI Compressor或谷歌Closure)中看到的典型Javascript缩小技巧。

经过模糊处理的代码看起来更像是加密的。不像我以前见过的任何东西。

我的印象是，一些企业(例如:JackBe)将加密的JavaScript代码放在*.gif文件中，而不是JS文件中，作为一种额外的混淆措施。
