Cron Key is a module that adds various utility functions for the Drupal cron system. As of July 29, 2013, this project is under new maintainership.
The Drupal 6 version was originally contributed by doq and protects "cron.php" against unauthorized access. This version is no longer supported.
The Drupal 7 version adds a "Reset cron key" button on the system Cron page that changes the system

Drush commands are available that display the system cron key (
drush cron-key) and reset the system cron key (
Cron Key is supported and maintained by the Larks at Exaltation of Larks. The Drupal 7 version was created and contributed as an instructional example at Droplabs during Drupal Module Development Boot Camp lab hours.
