Signatus, ergo securus? Who can sign what with TUF and Sigstore

Photo by Brett Jordan on Unsplash Sigstore is an open-source project and service run by the OpenSSF to make signing software easy! Before Sigstore, a developer who wanted to sign software needed to manage a GPG key. With Sigstore, they can use their identity (for instance, a Gmail account) to sign. It also brings transparency: actions must be posted on a public log, so they can be audited to detect bad behavior and to analyze damage after-the-fact.
