| Spec score · Code Signing Software | 8.5 (#3) | 7.6 (#15) |
| Intended users | The Sigstore integration guidance identifies open-source package managers as primary stakeholders for artifact signing and verification workflows. | The platform is designed for software-platform publishers that run third-party applications or plug-ins, and for ecosystems where multiple tools handle high-value content. |
| Notable limit | Cosign generates ECDSA-P256 keys and uses SHA256 hashes for ephemeral keyless and managed-key signing. | Code signing alone does not defend a platform or its modules against reverse engineering; PACE points to Fusion and White-Box Works for additional protection. |
| Purpose | Cosign signs and verifies OCI containers and other software artifacts. | The platform lets software publishers verify that third-party applications and plug-ins come from trusted developers and have not been modified. |
| Support | The project directs users with issues to open a GitHub issue or ask in its Slack channel. | PACE says customers receive full documentation, quality support, and access to its engineering team. |

In their own words
Cosign
Cosign is a free tool for signing and verifying OCI container images and other software artifacts. It can store container signatures in an OCI registry and publish generic artifacts through OCI. Supported targets include blobs, binaries, scripts, configuration files, SBOMs, WASM modules, Tekton bundles, eBPF modules, and in-toto attestations whose payloads use DSSE. Its default keyless workflow uses temporary keys held in memory, short-lived certificates from Sigstore’s Fulcio certificate authority, and entries in the Rekor transparency log. Other signing options include hardware and KMS-backed keys, encrypted keypairs generated by Cosign, and user-provided PKI. Cosign supports CI/CD signing, with guidance for GitHub Actions and GitLab CI/CD. Offline verification is possible when the image and signature materials are available locally and a trusted root is supplied. The project describes Cosign as a legacy signing system and recommends Sigstore-go for verification integrations. Its CLI-focused design has no API stability guarantees, and the documentation does not recommend it for application integration.
