This hack can be helpful for Clans and groups in RPG's. You can communicate with each other using encrypted text in any forum or Chat/IRC using an agreed upon key or set of keys for encoding the text.

OVERVIEW:

This adds a popup window to your forum that allows you to encrypt and decrypt text that you enter using an encryption key of your choice (up to 6 digits). Enter the text that you want to have encrypted/decrypted in to this text area. Then, enter an encryption key (this can be up to 6 digits long) and press the "encode message" button. You can click the "encode message" button as many times as you want, just be sure to remember how many times you clicked it (as well as the encryption key) so you can decode it properly later. Then paste the encrypted text in to your post or message and only those with the proper key(s) to decode the message can read it.

To decode messages enter the encrpyted text in to this box and enter the proper encryption key and press "decode message" to reveal the hidden text.

You can use multiple keys for encryption, but just be sure to remember to reverse the process (for example: use 123456 as the first key, and then encrypt, then enter a new key of 999999 for the second key. To decode you need to reverse the process: first use 999999 and then 123456. Obviously, the more levels of encryption you use the harder it will be for unwanted parties to "crack the code" and read your encoded messages.

The popup window also features instructions on encoding and decoding via a scrolling button.

The contents of the window can also be highlighted, and if you are using Internet Explorer then the contents of the window are copied to your clipboard. If you are using another browser simply press control and C on your keyboard to copy the highlighted text to the clipboard. There are also CLEAR FORM and CLOSE WINDOW buttons.

INSTALL INFO:

1) Upload the contents of the "UPLOAD" directory to your forum ROOT directory.

2) Go to ADMIN CP -> STYLES & TEMPLATES -> ADD NEW TEMPLATE and create a template called encrypto with the contents of template.encrypto.txt.

3) Go to Adimin CP ->Styles & Templates -> Edit Templates and open the NAVBAR template and search for the following:

<tr><td class="vbmenu_option"><a href="subscription.php?$session[sessionurl]">$vbphrase[subscribed_threads]</a></td></tr>

BEFORE add:

<td class="vbmenu_option"><a href="#" onclick="window.open('encrypt.php','Encryption','statusbar=no,menubar=no,toolbar=no,scrollbars=no,resizable=no,width=400,height=560'); return false;">Encryption</a></td></tr>

4) That's it! Go to http://yoursite.com/forum/encrypt.php or visit the Quick Links in your NAVBAR to view your new vBCrypto page.

Very nice hack. I would use it if I wasnt afraid of my members using it in their posts.

I will add usergroup restrictions.

[Corriewf]

What would be cool is if it was based on usergroup and I could set the key for each user group so I would always now whats being said and everything could be controlled by the admin.

What do you think?

good grazie :devious:

very nice, but i'd hardly call it encryption...

Obviously, the more levels of encryption you use the harder it will be for unwanted parties to "crack the code" and read your encoded messages.

Incorrect i'm affraid. Your encryption technique functions (i think its refered to) as a group function. In other words for any two keys used one after the other there exists another key that does the encryption in one go.

eg if i was to use 1 followed by 1 its equivilent to me having just used 2 once.

Very nice hack. I would use it if I wasnt afraid of my members using it in their posts.

Don't get under any illusions, this ISN'T very strong. There are infact only 26 possible different keys. 27 is the same as using 1 If you are worried about your members using it, do the following to read what they are saying:

Put the text into the box, set the key as 1 hit decode, see if its readable if not hit decode again, do this untill you get a message out.

I'd say this is a great hack for luring your members into a false sense of security... Then finding out what they REALLY think about you

Sorry if this comes over as a little bit harsh, but i'm fairly compatent when it comes to encryption/decryption theory... There are far better ways you can provide encyption, i've got a php script that does a bit of encryption, only prob is it dosnt' decrypt it very well at all... maybe i should work on that some more and turn it into a vb hack if people woulld be interested...

Would be nice to see it use blowfish encryption.
