implementing-code-signing-for-artifacts
Implements code signing for build artifacts (binaries, packages, containers) using GPG, Sigstore, and platform-specific signing tools, establishing trust chains and verifying signatures in deployment pipelines. Use when establishing artifact integrity checks against supply-chain tampering, proving authenticity to customers, building zero-trust pipelines that reject unsigned artifacts, or meeting SLSA Level 2+ provenance requirements.

# 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).
