      Fulcio is a free code signing Certificate Authority, built to make
      short-lived certificates available to anyone. Based on an Open ID Connect
      email address, Fulcio signs x509 certificates valid for under 20 minutes.

      Fulcio was designed to run as a centralized, public-good instance backed
      up by other transparency logs. Development is now underway to support
      different delegation models, and to deploy and run Fulcio as a
      disconnected instance.
