Add an Artifact Signing (SscaArtifactSigning) step to an existing Harness pipeline to Cosign-sign container or local-stage artifacts with keyless, key-based, or Vault signing. Supports Third-Party registries (Docker, ECR, GCR, GAR, ACR), Harness Artifact Registry (HAR), and Harness Local Stage artifacts. Place after image build/push; optionally upload .sig to the registry. Only works with existing pipelines. Use when asked to sign artifacts, add artifact signing, Cosign sign image, attach signature to registry, or configure SscaArtifactSigning. Trigger phrases: sign artifact, artifact signing, sign image, Cosign sign, add signing step, SscaArtifactSigning, attach signature, sign container image, HAR signing.
