This guide details implementing robust code signing for various build artifacts, including binaries, packages, and containers. It covers both traditional GPG key-based signing and modern, keyless signing using Sigstore/cosign. Use this process to establish verifiable trust chains, ensure artifact integrity against supply-chain tampering, prove authenticity, and meet advanced security standards like SLSA.

Cosign is a powerful Sigstore tool designed to secure container images and OCI artifacts. It allows users to sign and verify image provenance using both traditional key-based methods and modern, keyless OIDC workflows. This skill covers generating signatures, attaching critical metadata like SBOM and SLSA attestations, and implementing admission controls for robust supply chain security.

A comprehensive guide for securing container registries by enforcing vulnerability scanning (Trivy, Grype), generating Software Bill of Materials (SBOM), and implementing digital signing using Cosign and Sigstore. This solution is essential for establishing robust CI/CD pipelines and preventing supply chain attacks before image promotion.

This guide details how to implement secure, keyless software signing using the Sigstore ecosystem components (Cosign, Fulcio, Rekor). It establishes cryptographic provenance for container images and binaries by binding identity via OIDC, ensuring verifiable integrity and tamper-proofing throughout the CI/CD supply chain.

This skill provides methods to verify artifact signatures and SLSA provenance using tools like cosign and slsa-verifier. It is crucial for building secure CI/CD pipelines, detecting supply-chain attacks (e.g., tampering, compromised builds), and ensuring that deployed artifacts originate from trusted sources and build environments. Key features include enforcing keyless OIDC identity pinning and validating SLSA Build Levels.
