It’s ten o’clock, do you know where your private keys are?

Short-lived certificates are great — a short lifetime removes the need for complicated revocation policies and reduces an attacker’s window of opportunity. Yet using short-lived certificates in the software supply chain brings a lifetime problem: how can users trust artifacts after the certificate’s expiration? Repeatedly signing artifacts and requesting certificates is tedious. Really, distributors only need to prove that artifacts were signed when the certificate was valid… with timestamps! Enter SigStore’s new, free, open-source RFC 3161 timestamping service on the transparency log Rekor!

Cosign 1.0!

The cosign project started in February 2021 with a goal of making it easy to sign and verify containers on any OCI registry today. The community support has been incredible! We’ve added 7 maintainers from 5 organizations, and have merged 394 commits from 32 contributors across 10 organizations. Cosign has been tested on 13 OCI registries and is now packaged in five different package managers. We’ve cut seven releases over six months and are now thrilled to declare our first general availability release, cosign 1.

Cosign 1.0

It’s happening! Cosign’s 1.0 release is slated for July 28. If you were curious before but were hesitant about a pre-release project, now’s a good time to try it out and leave some comments. For the initial release we plan on supporting: * Signing images with KMS (GCP, AWS, Azure, Vault), YubiKeys, and locally stored keys * Verifying image signatures using the same, plus public keys specified by URL * Verifying images in Dockerfiles * Uploading & signing arbitrary blobs (and 📄✍🏻👨🏻‍🦳 🇺🇸SBOMs🦅) * Stable APIs in pkg/ for integrating Cosign into build systems and policy engines
