Guys/Gals I have made a website but now I want to encode the script so that no one can copy.

I'm using PHP, JavaScript and HTML in each page of my website. So how do I encrypt each and every page?

Thank You.

Umm, browsers need unencrypted data to... You know, show the page? – Andrew Dunn Sep 24 '10 at 5:28

Are you sure somebody would be interested in your HTML? – Your Common Sense Sep 24 '10 at 5:42

Firefox and firebugs "save dom as HTML" function is going to give anyone the DOM that firefox is rendering... hard to encrypt that. – Michael Anderson Sep 24 '10 at 6:39

Neither html nor javascript can be encrypted, else the browsers would not be able to interprete it and your visitors would not be able to view your site. Dot. End. Compression tools may boost performance a little but will not really help against copyright infringement.

Your php-programs generate html, your visitors will always be able to see your html, but if your server is configured properly no one should ever see your php.

PHP

No need to encrypt - noone will ever see it (unless your site has security problems).

JavaScript

You can pack it. Can be reversed.

HTML

You can remove all whitespace. This is problematic with pre and white-space: pre.

It is also very ease to export the formatted DOM structure that is the end result of your serialised mess.

The Most Important Part

Obfuscate to make pages load faster - not to stop people from stealing your code/markup. If your code is really worth stealing (which I doubt it, no offense), then people will get it.

And why make it slower? – griegs Sep 24 '10 at 5:29

@griegs Sorry, I don't understand? – alex Sep 24 '10 at 5:30

@griegs I think I know what you mean. It's not like a (good) professional web developer can't look at pretty much every site on the web and know how it was done just by observing it. – alex Sep 24 '10 at 5:33

Mind you, have you seen 5416339's webpage. Maybe a little paranoid to begin with. :) – griegs Sep 24 '10 at 5:37

+1 for the last part. – Bobby Sep 24 '10 at 14:15

Just get comfortable with the idea that putting something on the web is to open it to the world.

Cost in attempting to stop duplication of the stuff you've already decided to make publicly available: $your hourly rate x hours == ??

Cost to stop worrying about something that doesn't actually cost you anything: zero. winner.

(And to head off another question you're inevitably going to ask at some point in future - Don't attempt to disable right-clicks. It just annoys everyone and doesn't achieve anything.)

Try using Javascript Obfuscator for your javascripts. It will not hide you script but it protects JavaScript code from stealing and shrinks size.

There are plenty of De-Obfuscators around. – griegs Sep 24 '10 at 5:32

if you do a google on "html encryption" you'll get a lot of hits.

http://www.developingwebs.net/tools/htmlencrypter.php

The question I have is why you would want to do this? You're going to have a performance hit for what gain?

You can also do the same for javascript but unless your html or javascript has organisational sensitive data then... And if they do then perhaps that's not the best place for it.

They're user unfriendly, as users with JavaScript disabled won't be able to see your website. – Andrew Dunn Sep 24 '10 at 6:12

Actually one way to do it is to use XML + XSLT, it's extremely difficult for a lay-person to figure out what is going on, even more difficult for them to get your sauce code.

A layperson probably won't attempt to do anything with your code anyway, and everybody else will just process the XML, as the browser needs to anyway, and they get the result. Also: Mmmmm, sauce code... ^_^ – deceze Sep 24 '10 at 5:53
True, but I don't thing the average person who steals source/sauce code will even know what an XSL Transformation is, let alone how to reverse it. Besides, you can do trippy stuff, like making all of your html tags backwards <lmth><daeh><eltit>My Website</eltit></daeh><ydob>...</ydob></lmth> It's the closest thing to html encryption there is. – Andrew Dunn Sep 24 '10 at 6:08

And the shortest way to the madhouse, too. :D – deceze Sep 24 '10 at 6:18

search google for ioncube http://www.ioncube.com/html_encoder.php

This converts the html into gibberish. Stealing your html becomes difficult.

Nobody's html code is worth stealing anyways. This is only for self satisfaction.

HTML encoder = horrible waste of time. Also relies on Javascript, which is bad. +0.5 for the last sentence though. – deceze Sep 24 '10 at 6:08
Sounds like search engines would have a hard time indexing your site too. – alex Sep 27 '10 at 15:19
