Flow Chart

Deploy this in your own products to ensure they are only used by whom has the right.

Ensure your product is not stolen with this easy to use system. Integrate the generation system in with your billing software and supply your customers with an authentication key. With this they can authenticate there script or software via the net. Key authentication does not require the Keyauth PHP Class, so you can deploy the keys on any platform or scripting language.

With the addition of a match string as a second level of security, the end-user would be required to supply a valid key along with the corresponding match key. This match key could be the domain or IP address of the server where the script lives. With this, you can ensure its used only on a single server, by a single user.

Examples

With just a few lines of code, you can create a fully unique key.
include("keyauth.class.php");

$keyauth = new Keyauth;
$keyauth->key_unique = TRUE;
$keyauth->key_store = TRUE;

$key = $keyauth->generate_key();

echo $key;

This is how easy it is to implement client side.

$key = "81I3-MD1F-DJRL-5D6N-9551";

$auth_url = "http://yoursite.com/auth/server.php?key={$key}";
$data = file_get_contents();
$result = json_decode($result);

if($result['valid'] != true){
    die("Invalid Key.  Script Stopped!")
}

Please note, these are very crude examples and are kept small for the sake of this page. Much more can be accomplished in a real environment.
