Individual skill
implementing-code-signing-for-artifacts
This skill covers implementing code signing for build artifacts to ensure integrity and authenticity throughout the software supply chain. It addresses signing binaries, packages, and containers using GPG, Sigstore, and platform-specific signing tools, establishing trust chains, and verifying signatures in deployment pipelines.

# Implementing Code Signing for Artifacts
## When to Use
- When establishing artifact integrity verification to prevent supply chain tampering
- When compliance requires cryptographic proof that build artifacts are authentic and unmodified
- When distributing software to customers who need to verify publisher identity
- When implementing zero-trust deployment pipelines that reject unsigned artifacts
- When meeting SLSA Level 2+ requirements for provenance and integrity
**Do not use** for encrypting artifacts (signing provides integrity, not confidentiality), for container image signing specifically (use cosign), or for source code authentication (use commit signing).
