[PHP] RC4 Encrypted IP Logging

This is my first post on this forum, so I hope you enjoy it.

Download this PHP class (not written by me; credits inside it). Make sure to include our class inside the web folder, and that we have a html file in our folder also. Call the html file "log".

Then we use the following code on our page:

Code:

$ip = $_SERVER['REMOTE_ADDR'];
$date = date("d-m-y / H:i:s");
$crypto = &new RC4();
$eIp = $crypto->encrypt("ENCRYPTION KEY", $ip);
$eDate = $crypto->encrypt("ENCRYPTION KEY", $date);
$file = fopen("log.html", "a");
fwrite($file, "IP Address: " . $eIp . "<br />" . "Date: " . $eDate . "<br /><br />");

That will RC4 Encrypt our log so that no one knows who visited the certain page and what time. You can add things to it such as the page it was referred by etc.
Using this method is an alternative to using MySQL to log.

MAKE SURE TO REMEMBER YOUR KEY, OTHERWISE IT WILL BE ALMOST IMPOSSIBLE TO RECOVER THE DATA.
