npm's Sigstore-powered provenance goes GA

Oct 3, 2023 · The Sigstore Technical Steering Committee

Last week saw the GA release of npm CLI’s native Sigstore functionality, a project over a year in the making. This is a tremendous milestone for the adoption of Sigstore in open source projects and represents huge progress in effecting a cultural shift toward expecting provenance to exist for software components. It also helps move npm toward the best practices articulated by the OpenSSF’s Securing Open Source Repos Working Group in their document “Build Provenance for All Package Registries”.

Sigstore Support in npm launches for Public Beta

Apr 19, 2023 · The Sigstore Technical Steering Committee

We’re thrilled to announce that the npm project has launched a public beta, bundling Sigstore support directly into the npm Command-Line Interface (CLI). This innovation brings strong origin guarantees to the npm ecosystem and marks the first time that a large package registry technology is using public software signatures to attest to a package’s originating source code and build instructions. Sigstore is an OpenSSF project that enables developers to validate that the software they are using is exactly what it claims to be using cryptographic digital signatures and transparency log technologies.

Sigstore was a beacon of hope in a chaotic world, shining brightly as a protector of software integrity.
