New Terraform Modules Repository

New Terraform Modules Repository The Terraform modules for running a private deployment of Sigstore have been moved to a dedicated repository, terraform-modules. We currently support Google Cloud Platform as a cloud provider. We welcome any community contributions for other cloud providers. Deprecation for Terraform Modules under Scaffolding Effectively immediately, the Terraform modules in the scaffolding repository will no longer be updated. If you are relying on Terraform for your private deployment, please update references for scaffolding to the new terraform-modules repository.

Using rekor-monitor to Scan Your Transparency Logs

Overview As part of the tool suite within Sigstore that focuses on providing transparency in the software supply chain, Rekor, Sigstore’s signature transparency log, and Fulcio’s certificate transparency log provides discoverability and auditability for signed artifact metadata and code-signing certificates. These immutable read-only logs help secure the software supply chain by making it easier to show what actions have been performed by a compromised identity. A variety of different improvements have recently been integrated into rekor-monitor to make it easier to use.

PyPI's Sigstore-powered attestations are now generally available

Check out the PyPI blog and Trail of Bits blog for more user-facing and technical details, respectively! Over the past year, the Google Open Source Security Team and Trail of Bits have worked together to implement PEP 740, a Python packaging standard that allows users to upload Sigstore-based attestations to the Python Package Index. Today we’re pleased to announce that attestation support on PyPI is generally available, meaning that project maintainers can submit attestations for both PyPI and downstream users to verify.

Fulcio Streamlines Onboarding for CI Identity Providers

TL;DR Fulcio, the Sigstore certificate authority, has introduced a new feature that simplifies the onboarding process for identity providers, mainly for continuous integration. This enhancement eliminates the need for complex, provider-specific logic implementations. Traditionally, integrating a new identity provider for CI involved significant development effort, which required understanding the codebase and cutting a new release. However, with this update, onboarding is reduced to configuring a YAML file which houses essential provider information for building certificate extensions based on ID token claims.
