Sigstore: Secure and Scalable Infrastructure for Signing and Verifying Software

Sigstore is an open-source project that aims to provide a transparent and secure way to sign and verify software artifacts. It is an initiative that is part of the Open Source Security Foundation (OpenSSF), and it aims to establish standards for software signing that are both easy to use and widely adopted.

Sigstore can sign and verify any software artifact, including container images, source code, NPM packages, and more! It provides a simple and easy-to-use API for developers, as well as command-line tools and integrations with popular software development platforms.

In this talk, we'll dive into the architecture and internals of Sigstore and keyless signing, along with the security considerations that drove the design. We'll examine how you can reuse your existing identity infrastructure to produce signed artifacts without worrying about protecting long-lived keys. We'll also examine how you can use these signatures to enforce runtime policies on signing identities.
