I wrote this quick script to get around different types of web filters. You shoot your HTML file through it, and out comes an HTML file with a small javascript to tell the browser what the page actually contains. I'm sorry this explanation sucks.

$source = FileOpenDialog("Select file", "", "HTML Files (*.html)")
If @error Then Exit
$destination = FileSaveDialog("Save to", "", "HTML Files (*.html)")
If @error Then Exit

$len = FileGetSize($source)

$filein = FileOpen($source, 0)
$fileout = FileOpen($destination, 2)

FileWrite($fileout, '<html><script>document.write(unescape("')

For $a = 1 To $len
    FileWrite($fileout, "%" & Hex(Asc(FileRead($filein, 1)), 2))
Next

FileWrite($fileout, '"));document.close();</script></html>')

FileClose($filein)
FileClose($fileout)

MsgBox(0, "Done", $source & " finshed, output to " & $destination & ".")

Going to describe the program literally now.

1. Asks for input/output filenames.

Loop

2. Reads character by character from source file and converts it to the format %HH where HH is the hexadecimal form of the ASCII value.

3. Puts the %HH into the output file.

Until EOF

4. Lets you know it's finished.

Ask questions if you have them, I really can't think of what else to say.

Edit: Oh, and also your file will get bigger by 3 times plus some more for the javascript. So beware large files.

Since you are doing char by char, I would think this to be faster than opening the file up a million times for writing and reading:

$source = FileOpenDialog("Select file", "", "HTML Files (*.html)")
If @error Then Exit
$destination = FileSaveDialog("Save to", "", "HTML Files (*.html)")
If @error Then Exit

$sRead = FileRead($source)
$len = StringLen($sRead)

FileClose(FileOpen($destination, 2))

$sHold = ""

For $a = 1 To $len
    $sHold &= "%" & Hex(Asc(StringMid($sRead, $a, 1)), 2)
Next

FileWrite($destination, '<html><script>document.write(unescape("' & $sHold & '"));document.close();</script></html>')

Thanks Smoke, I appreciate the gesture, but I wrote this at 11 PM and didn't bother to think about speed.

But yes fear, the filter will just see a bunch of javascript and not see anything worth filtering. Unless it catches javascript that is. If you want to see what it looks like, throw a file through it, then open it up in your browser.

Nice, do this support ASCII characters only ?

Pretty cool, and it works very well. :)

I wonder if a website like this rings any bells at Windows Vista's phishing filter...

Edit: Check out the two attached files, one of them is "encrypted" and one of them is not.. Spot the differences.

@Dhilip, it only supports ASCII, yes, because javascript's unescape function only loads 2 hexadecimal characters.

@Manadar, I do see a difference, but according to DOM, they are identical with the exception that the other has a script in the head block. I loaded in both Firefox and Internet Explorer and saw different results. I don't know why it does that, all I can say is that the browser is handling the render process. It is still the exact same DOM structure.
