青春惊慌失措

I created an HTML page and now would like to hide the source code and encrypt it.

How can I do that?

There isn't really anyway to do it that would stop a someone who is sophisticated.

You cannot hide the source code, but you can add some difficulties to see your source code by following way

1. Disable right-click:

<body oncontextmenu="return false">

2.Disable ctrl, u, F12 keys:

<script type="text/javascript">
    function mousehandler(e) {
        var myevent = (isNS) ? e : event;
        var eventbutton = (isNS) ? myevent.which : myevent.button;
        if ((eventbutton == 2) || (eventbutton == 3)) return false;
    }
    document.oncontextmenu = mischandler;
    document.onmousedown = mousehandler;
    document.onmouseup = mousehandler;
    function disableCtrlKeyCombination(e) {
        var forbiddenKeys = new Array("a", "s", "c", "x","u");
        var key;
        var isCtrl;
        if (window.event) {
            key = window.event.keyCode;
            //IE
            if (window.event.ctrlKey)
                isCtrl = true;
            else
                isCtrl = false;
        }
        else {
            key = e.which;
            //firefox
            if (e.ctrlKey)
                isCtrl = true;
            else
                isCtrl = false;
        }
        if (isCtrl) {
            for (i = 0; i < forbiddenKeys.length; i++) {
                //case-insensitive comparation
                if (forbiddenKeys[i].toLowerCase() == String.fromCharCode(key).toLowerCase()) {
                    return false;
                }
            }
        }
        return true;
    }
</script>

3. Add to lots of white spaces to before you staring your codes

it may fool someone

There isn't really a way to do that. Perhaps the only thing you could do is to disable the right click feature via JavaScript, but still that wouldn't stop a user who's experienced enough to copy it. However, check this out.

You can disable the right click, but that's a bad idea because expert minds can read anything from your page. You cannot totally hide the page source - this is not possible. Nothing is secure enough on the Internet.

In any case, you can encrypt it and set a password. You can utilise this link - it will encrypt your HTML page with a password.

First up, disable the right click, by writing out this script, right after the tag.
```
<SCRIPT language=JavaScript>



var message = "function disabled";

function rtclickcheck(keyp){ if (navigator.appName == "Netscape" && keyp.which == 3){ alert(message); return false; }

if (navigator.appVersion.indexOf("MSIE") != -1 && event.button == 2) { alert(message); return false; } }

document.onmousedown = rtclickcheck;

</SCRIPT>
```
Then, encrypt all of it, in this website, called 'AES encryption'.

Link - http://aesencryption.net/

You need to set a password to decrypt it ....you choose the password.

After encrypting it, you can just write a basic HTML page just putting into the <head> tag once again the script to disable the right click, into the <body> tag you code and hide everything just writing at top of the page <html hidden>.

Example
```
<!DOCTYPE html>
<html hidden>
<head>
<SCRIPT language=JavaScript>



var message = "function disabled";

function rtclickcheck(keyp){ if (navigator.appName == "Netscape" && keyp.which == 3){ alert(message); return false; }

if (navigator.appVersion.indexOf("MSIE") != -1 && event.button == 2) { alert(message); return false; } }

document.onmousedown = rtclickcheck;

</SCRIPT>
</head>
<body>
--here, you put the encrypted code from the link above--

</body>
</html>
```
Where it is written var message = "function disabled"; you can write for example something like 'This page cannot be viewed' or something which will annoy most of the users and will just leave. ['This page is unavailable' and so on ....].

Finally, you will see a blank page with a message coming up as soon as you right click the page. The message will be something like 'This page is no longer active'.

Example
```
  <SCRIPT language=JavaScript>

    

    var message = "**This page is no longer active**";

    function rtclickcheck(keyp){ if (navigator.appName == "Netscape" && keyp.which == 3){ alert(message); return false; }

    if (navigator.appVersion.indexOf("MSIE") != -1 && event.button == 2) { alert(message); return false; } }

    document.onmousedown = rtclickcheck;

    </SCRIPT>
```
I do know that one can remove the <html hidden> or the Javascript script with some add-ons such as Firebug but anyway you will need to decrypt the code with a password in order to see the real page. Expert users might view the source code with a Brute Force attack, I think. So, nothing is safe.

I found out an application that you need to instal on your computer. There is a feature in the Enterprise version but you must pay to get it. This feature is a tool which encrypt your HTML page creating an ultra-strong password encryption for HTML files using up to 384 bit keys for encryption [the link I wrote above uses up to 256 bit keys for encryption]. I have never tried it out, though, because it is not for free.

Anyway, the link of the software 'HTML Guardian' - http://www.protware.com/default.htm For the feature about the encryption, merely click on 'Ultra-Strong HTML password protection' in the page.
