We have finally completed a GLOBAL certificate look-up table for real-time notifications in our re-designed KeyChest service. KeyChest has been using an external service to check for new certificates. This has become unsustainable due to the number of users and certificates we monitor.
While implementing features of the certificate planner, we have added a few handy features to the KeyChest spot checker as well. It is now much more than just a tool to check when a website certificate expires.
