This script shows how you can create license keys (eg. trial keys) without having to be logged in. It can be used if you would like to share license key creation permission with other people, eg. affiliates and resellers.
You should only need PHP and some web server software (eg. Apache or Nginx) to host this code.
Support for TLS (eg. when the url starts with https://) is preferable.
For testing, assuming you have PHP 5.4 or later installed, you can test this script by running:
php -S localhost:8000
Before you set this up production, please open create-key.php and change secret and token as described in the comments.
Once you have uploaded this script to your server, you should be able to visit create-key.html and see a form for key creation.
However, for everything to work, you need to append auth=<secret> to the url. That is, assuming secret=verysecretkey, you need
to visit create-key.html?auth=verysecretkey. From this point, everything should work.
Note: You should only share this url with those that you trust. If you would notice that you have lost control of the script, you can, at any time, remove the access token on this page.
