The record

Purpose: RHTAS simplifies cryptographic signing and verification of software artifacts, including container images, binaries, and Git commits.
Sigstore: Red Hat describes Trusted Artifact Signer as a production-ready enterprise deployment of the Sigstore project.
Signing clients: Its Sigstore client tools include cosign, gitsign, and rekor-cli for generating and verifying signatures.
Transparency log: The certificate transparency log records signing events in a permanent, immutable ledger that the page says is inaccessible to the public.
Identity and keys: RHTAS supports identity-based signing through OpenID Connect and can use existing self-managed keys maintained in a third-party key management system.
Integrations: Red Hat lists Podman, Quay, Ansible, Red Hat Advanced Cluster Security, StoneSoup/HACBS, and Red Hat Trusted Content among products adopting or integrating Sigstore.
OIDC providers: The deployment guide describes configuring Red Hat SSO, Google, Amazon STS, GitHub, Red Hat build of Keycloak, and Microsoft Entra ID as OIDC providers.
Deployment platforms: The deployment guide covers Red Hat OpenShift Container Platform and Red Hat Enterprise Linux; supported-platform information also lists Amazon EKS as a development preview for RHTAS 1.4.
Downloads: Red Hat's download page lists CLI binaries for Windows, macOS, and Linux.
SLSA: Red Hat says RHTAS can help enterprises meet signing-related criteria for Supply-chain Levels for Software Artifacts (SLSA) compliance.
Production support: Red Hat states that support for RHTAS is subject to its Production Scope of Coverage, Service Level Agreement, and product life cycle, and includes help with setup, administration, deployment, and configuration.
Lifecycle: Red Hat describes full support and maintenance support phases and says a release reaches end of life after its maintenance phase.
Deployment prerequisite: The OpenShift deployment guide requires OpenShift Container Platform 4.16 or later, cluster-admin access, an OIDC provider, and the oc command-line tool.
Technology preview limitation: The administration guide marks signing and verifying AI/ML models with the CLI as Technology Preview and says Technology Preview features are not supported by production SLAs.
