Red Hat Trusted Artifact Signer
Raleigh, North Carolina, USA
What it is
Red Hat Trusted Artifact Signer (RHTAS) is a hybrid deployment for signing and verifying software artifacts, including container images, binaries, documents, source-code commits, software bills of materials, build artifacts, and AI/ML models. Red Hat describes it as a production-ready enterprise deployment of Sigstore. The cosign, gitsign, and rekor-cli clients create and verify signatures. Signing can use OpenID Connect identities or existing self-managed keys in a third-party key management system. A certificate transparency log keeps signing events in a permanent, immutable ledger that Red Hat says is inaccessible to the public. Deployment guidance covers Red Hat OpenShift Container Platform and Red Hat Enterprise Linux; Amazon EKS is a development preview for RHTAS 1.4. OpenShift deployment requires version 4.16 or later, cluster-admin access, an OIDC provider, and the oc command-line tool. CLI binaries are listed for Windows, macOS, and Linux. Pricing is available on request, with a 60-day trial. AI/ML model signing through the CLI is marked Technology Preview and is not covered by production SLAs.
