Outils et frameworks de signature cryptographique d'artefacts logiciels pour garantir l'intégrité et la confiance dans la supply chain.
Cosign is a tool for signing and verifying software artifacts, primarily those stored in OCI-compatible registries such as container images, Helm charts, SBOMs, and Tekton bundles. It supports keyless signing using ephemeral keys and short-lived certificates from the Sigstore public-good infrastructure, associating signatures with an OpenID Connect identity rather than a long-lived cryptographic key. The project provides multiple signing and verification methods, including private keys, key pairs stored in KMS providers like AWS KMS and Azure Key Vault, and hardware security keys. It can sign
Cosign is a dedicated tool for cryptographically signing and verifying software artifacts, with first-class support for OCI containers, keyless and key-based signing, attestations (SBOM, in-toto), and CI/CD integration, making it a flagship match for supply chain artifact signing and verification.
Skopeo is an OCI container image manager and registry client designed for inspecting, copying, and signing container images across different registries and storage backends. It enables the manipulation of container images using direct API calls to registries, operating independently of a local container daemon or runtime. The tool provides specialized capabilities for container image mirroring and synchronization, specifically supporting the mirroring of external repositories to internal registries for air-gapped environments. It also functions as a container image signing tool, allowing for
Skopeo is a container image management tool that includes signing and verification of OCI images, which directly addresses the intent for container artifact signing, but its focus on containers means it does not natively handle binaries or packages or provide full attestation and policy features.
Notary is a project that allows anyone to have trust over arbitrary collections of data
Notary uses cryptographic signing and verification via The Update Framework to secure container images and arbitrary data, directly addressing the need for artifact integrity and provenance in the software supply chain, though its attestation support is limited.
