Fulcio Overview

Fulcio is a free code signing Certificate Authority, built to make short-lived certificates available to anyone. Based on an OpenID Connect email address, Fulcio signs X.509 certificates valid for 10 minutes.

Fulcio was designed to run as a centralized, public-good instance, auditable by a certificate transparency log. Fulcio can also be deployed as a self-hosted service.

Fulcio is being developed as part of the sigstore project. Join us on our Slack channel (need an invite?)

You can learn more about Fulcio in the Fulcio repo and the repo docs.
