What Red Hat Trusted Artifact Signer is
Red Hat Trusted Artifact Signer (RHTAS) helps organizations sign and verify 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 an enterprise deployment of Sigstore. Its client tools include cosign, gitsign, and rekor-cli for creating and checking signatures. Signing can use OpenID Connect identities or existing self-managed keys held in a third-party key management system. A certificate transparency log records 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 listed as a development preview for RHTAS 1.4. The OpenShift deployment guide requires OpenShift Container Platform 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, and a 60-day trial is listed. Signing and verifying AI/ML models with the CLI is marked Technology Preview and is not supported by production SLAs.
