It supports both key-based and keyless (OIDC) signing, integrates with Fulcio (certificate authority) and Rekor (transparency log), and enables supply chain security for container images.\n\n\n## When to Use\n\n- When deploying or configuring implementing image provenance verification with cosign capabilities in your environment\n- When establishing security controls aligned to compliance requirements\n- When building or improving security architecture for this domain\n- When conducting security assessments that require this implementation\n\n## Prerequisites\n\n- Cosign CLI

--certificate-oidc-issuer=https:\u002F\u002Faccounts.google.com\n```\n\n## Best Practices\n\n1. **Use keyless signing** in CI\u002FCD for automated pipelines\n2. **Sign by digest** not by tag for immutable references\n3. **Attach SBOM attestations** alongside signatures\n4. **Enforce signatures** at admission with policy-controller or Kyverno\n5. **Use OIDC identity** verification instead of just key verification\n6. **Store keys in KMS** (AWS KMS, GCP KMS, HashiCorp Vault) for key-based signing\n7. **Verify the full chain**: signature + certificate + Rekor inclusion\n8. **Include build metadata** as annotations on signatures\n",{"name":5,"tags":52,"author":57,"domain":38,"license":15,"version":58,"category":5,"nist_csf":59,"subdomain":34,"description":7,"mitre_attack":64},[32,53,54,35,27,55,56],"sigstore","image-signing","keyless","slsa","mahipal","1.0",[60,61,62,63],"PR.PS-01","PR.IR-01","ID.AM-08","DE.CM-01",[65,66,67,68,69],"T1610","T1611","T1609","T1525","T1195","main","5eea5b3296f4673b5f481e8bcc1ba76281149f16","modules\u002Fimplementing-image-provenance-verification-with-cosign",0,"https:\u002F\u002Fgithub.com\u002FHenriqueMC17\u002Fagente-core","https:\u002F\u002Fgithub.com\u002FHenriqueMC17","Qualquer
