This module enables basic CAPTCHA functionality: administrators can add a CAPTCHA to desired forms that users without the 'skip CAPTCHA' permission (typically anonymous visitors) have to solve.

Code

function captcha_cron() {

  // Remove challenges older than 1 day.
  db_delete('captcha_sessions')
    ->condition('timestamp', REQUEST_TIME - 60 * 60 * 24, '<')
    ->execute();
}
