Worthless tools for “protecting” HTML blanks out site in Opera?

I was trying to work out why parts of this website <http://www.islandsmultimedia.com> would appear as blank pages. It turns out they employ something called "HTML Protector" to make the source code unreadable.

First a general comment: encrypting HTML is not possible. I can load any "protected" page in any modern browser and see the source code in no time by typing

javascript:alert(document.documentElement.innerHTML)

The marketing of the HTML Protector software and relatives may be clever but their products are basically bogus. HTML is designed to be open. It is part of the reason why the Web developed as quickly as it did.

The "encryption" used by "HTML Protector" is as far as I can see to take each character in a string, lookup ASCII value, XOR it, turn the new number into a character and URL encode the whole output.

The reason why Opera does not display the page is that the script specifically detects Opera and decides it will display blank page instead:

if(navigator.userAgent.indexOf('Opera')!=-1)window.location="about:blank"

I suppose they have decided that Opera users are too smart and might get around their "protection".

  1. The site was entirely unusable in my IE6 because this bit of code:

    function hp_dc(){hp_ta.createTextRange().execCommand("Copy");setTimeout("hp_dc()",300)}

    caused my IE to ask me 3 times per second if I wanted to let the website access the clipboard. I can't imagine any reason why they want to access my clipboard and I CERTAINLY don't think they wanted to make it impossible to visit the site with IE. Just crap.

  3. Heh – I'm just catching up on your journal, and went looking for HTML protector's website. It specifically states…

    Disable Opera users – EXCLUSIVE!

    People using the Opera browser will be able to use the right-click menu on protected page even if "Disable right mouse button" option has been applied. This option gives you the ability to block all Opera users from viewing your pages.

    Amusing!

    How do they disable the view menu in ALL browsers ?
