You can't secure client side code: just press F12 on Google Chrome, pause javascript execution and you will get all strings, even those encrypted. Your source code will be replaced with completely unreadable code. After you complete the payment via the secure form, you will receive a license key instantly by email.


Avoid asking multiple distinct questions at once. See the page for help clarifying this question. If this question can be reworded to fit the rules in the , please. The only way to truly keep something secret is to not send it to the client.

If they don't have it, they can't read it. Sending it encrypted is just asking for trouble at the hands of the few people who actually care, and everyone else won't poke around even if you send it in the clear c. It will only inconvenience legitimate users eg. It is fundamentally impossible to prevent reverse-engineering of Javascript code. It can decrease load times by minifying. It's very easy to do and there are many tools see other answers , I'd say certainly do it as there are only advantages most of the time, but don't expect it to bring real security or to stop someone copying your code if they really want to.

The only way to do this is to keep code server side and use ajax. It's a very popular tool, built, enhanced and maintained by the Yahoo UI team. Of course, by packaging up your source into a garbled, minified mess, you have a light version of security through obscurity.

Most of the time, it's your user who is viewing the source, and the string values on the client are intended for their use, so that sort of private string value isn't often necessary. If you really had a value that you never wanted a user to see, you would have a couple of options. First, you could do some kind of encryption, which is decrypted at page load.

That would probably be one of the most secure options, but also a lot of work which may be unnecessary. You could probably base64 encode some string values, and that would be easier.. Encryption is the only way to truly prevent anyone from accessing your data, and most people find that to be more security than they need. Sidenote: Obfuscation in Javascript has been known to cause some bugs.

The obfuscators are getting a little better about it, but many outfits decide that they see enough benefit from minifying and gzipping, and the added savings of obfuscation isn't always worth the trouble.

If you're trying to protect your source, maybe you'll decide that it's worth your while, just to make your code harder to read.

I want to add that doing a base64 encode will be of no benefit to security, since it is a trivially reversable procedure. Even encrypting it won't help if it's decrypted client-side. The reason is that you'll have to give the browser the encryption key as well, and anything the browser can do the user can too.

Rewriting the private variables to a, b, c etc is usually safe. Another thing I do is make the minifier put a line break after each semi-colon in the code --line-break 0. Then in production if it errors I least have a valid reference line to work from and can find that code in my development copy. Otherwise you just end up with an error on a massive line of code and no idea where the error is.

It can also do type checking and will warn about syntax errors. For anyone who really wants to get at your code, it's just a speed bump. Worse, it keeps your users from fixing bugs and shipping the fixes back to you , and makes it harder for you to diagnose problems in the field. Its a waste of your time and money. Talk to a lawyer about intellectual property law and what your legal options are. Instead, Open Source is a particular licensing model granting permission to freely use and modify your code.

If you don't grant such a license then people copying your code are in violation and in most of the world you have legal options to stop them. The only way you can really protect your code is to not ship it. Move the important code server-side and have your public Javascript code do Ajax calls to it. You have little right to use it without the license. You don't have to sign it to get the rights. A license is different from a contract.

This is about punishing those who copy the file for use on their own site without permission. What you're talking about is a contract, not a license. Contracts require mutual assent and are a give and take. Licenses grant you right to use intellectual property. Licenses are one way the owner is granting you things , you are not required to sign because you are not giving anything away. Otherwise, anyone will always be able to keep track of all operations that the code is doing. Someone mentioned base64 to keep strings safe.

This is a terrible idea. Base64 is immediately recognizable by the types of people who would want to reverse engineer your code.

The first thing they'll do is unencode it and see what it is. Madbreaks: The question was in the context of not making his code open source. The immediate technical answer is the accepted one, but the better in-context answer as in, what are you really trying to do?

Either way both answers are here and people can read and benefit from both. 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.

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. And no, I'm any smarter than an average Jr. The simple fact is, there is NO way to obscure client side JS.

You can buy yourself 5 minutes, MAX, but that's of no use. No one who has ever written a line of JS would buy that crap. The one you see in the source code. What does this code? Obfuscate the code a little What is that? I gave it a spin recently and was impressed by it. It provides a set of templates for obfuscation with predefined settings for those who don't care much about the details and just want to get it done quickly.

The problem with interpreted languages, is that you send the source to get them working unless you have a compiler to bytecode, but then again, it is quite trivial to decompile. So, if you don't want to sacrifice performance, you can only act on variable and function names, eg. Obfuscating strings will have a performance hit, if you have to encrypt them and decrypt them in real time. Plus a JS debugger can show the final values... A non-open-source Javascript-based application is fairly silly.

Javascript is a client-side interpreted language.. Obfuscation isn't much protection.. If you are in a situation where you don't want your code to be public, Javascript isn't the right language.. You can't secure client side code: just press F12 on Google Chrome, pause javascript execution and you will get all strings, even those encrypted. If you're writing server side javascript i. But it just have a problem: it only work if you write in it's. It's not made for it, but works well doing it: it doesn't add extra code like some compilers which usually can be reversed which the tools I cited but changes it to uncommon ways, some even hard to undo, and remove unused code, which in comparison to real obfuscation is good for performance.

That said, I never tried integrating it in a build script of any kind. As for obfuscating vs. It makes debugging impossible Error at line 1... But if you need to... I would suggest first minify with something like YUI Compressor, and then convert all string and numbers to HEX Values using something like With this, the code would be rendered near impossible to understand and I think at this Stage it will take more time for a Hacker to re-enact your code than actually if he re-wrote from scratch.

Rewriting and Cloning is what you cant actually stop. After all we are free-people! I've been using for years and it is hands down the best obfuscator out there. It has an advanced UI but is still intuitive and easy to use. It will also handle HTML and CSS files. The best way to use it is to prefix all of your private variables with something like an underscore, then use the sort feature to group them all together and check them off as targets for obfuscation.

The engine will automatically tally up the number of targeted variables and prioritize them to get the maximum compression. I don't work for Jasob and I get nothing out of promoting them, just offering some friendly advice. The downside is that it's not free and is a little pricey, but still worth it when stacked against alternatives - the 'free' options don't even come close.

I am using Closure-Compiler utility for the java-script obfuscation. It minifies the code and has more options for obfuscation. This utility is available at Google code at below URL: But now a days I am hearing much of UglifyJS.

You can find various comparison between Closure Compiler and UglifyJS in which Uglify seems to be a winner. Soon I would give chance to UglifyJS.

If you use a JavaScript library, consider Dojo Toolkit which is compatible after minor modifications with the Closure Compiler's Advanced mode compilation. Code compiled with Closure Advanced mode is almost impossible to reverse-engineer, even passing through a beautifier, as the entire code base includinhg the library is obfuscated. It is also 25% small on average. JavaScript code that is merely minified YUI Compressor, Uglify etc.
