If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/bitnami-labs/sealed-secrets shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Sealed Secrets is a Kubernetes controller and CLI tool that enables one-way encryption of Kubernetes Secrets so they can be safely stored in version control (including public repositories). It uses asymmetric cryptography to encrypt secrets with a public key that only the controller (holding the private key) can decrypt, solving the problem of managing sensitive data alongside infrastructure-as-code. Dual-binary project: cmd/controller/ contains the Kubernetes controller reconciling SealedSecret CRDs into plain Secrets, cmd/kubeseal/ provides the CLI client for encrypting secrets locally. Prometheus monitoring integration in contrib/prometheus-mixin/ with Jsonnet-based dashboards and alerting rules. Helm packaging in carvel/ and Kustomize overlays in controller-norbac.jsonnet for RBAC-less environments.

Kubernetes cluster operators and DevOps engineers who want to store encrypted secrets in Git alongside their Helm charts and Kustomize manifests without exposing credentials. Platform teams using GitOps workflows (ArgoCD, Flux) who need to secure secrets in public or shared repositories.

Production-ready and actively maintained. The project has significant community adoption (visible from Docker Hub pulls badge), comprehensive CI/CD via GitHub Actions (.github/workflows/ci.yml, release.yaml), extensive test coverage (cmd/*_test.go files), and a structured Helm chart (carvel/package.yaml). Recent commits and active issue management indicate ongoing development.

Low risk for a security-critical tool. Dependencies are carefully managed (go.mod shows pinned versions for k8s.io, prometheus, and crypto libraries). The main risk is that sealed-secrets relies on cluster-specific keys—if lost, sealed secrets cannot be recovered. Single point of failure is the sealing key, mitigated by key rotation procedures documented in README. No obvious security vulnerabilities in dependency chain, though crypto libraries (golang.org/x/crypto) must be monitored.

Active development on Kubernetes 1.35 compatibility (go.mod shows k8s.io v0.35.4), Prometheus integration for observability, and release automation via .goreleaser.yml and cosign signing (.github/workflows/cosign.pub). Recent work on restricted environment support (controller-norbac.jsonnet), Helm 3 chart improvements, and OpenShift verification pipelines (.vib/vib-platform-verify-openshift.json).

• Kubernetes CRDs + client-go — Sealed-secrets extends Kubernetes natively; CRDs allow users to store encrypted secrets as first-class cluster resources alongside other manifests in git.
• RSA-4096 asymmetric encryption — Public key can be safely committed to git repos and shared; only cluster holds private key. Enables GitOps workflows where unencrypted secrets never leave the cluster.
• Golang + k8s.io/controller-runtime — Go's strong concurrency model and Kubernetes' own language choice enable efficient watch loops and cross-namespace reconciliation at scale.
• Helm for deployment — Standard Kubernetes package manager; users can version-pin sealed-secrets releases and manage RBAC/TLS certificates declaratively.
• Prometheus metrics — Observable reconciliation success/failure rates and encryption performance; operators can set alerts on degradation.

• One-way encryption only (decrypt only in-cluster)

  • Why: Simplifies key management (no need to rotate keys regularly for re-encryption) and eliminates risk of plaintext leaks during decryption outside cluster.
  • Consequence: Cannot easily view plaintext secrets once sealed; users must trust the cluster for unsealing.

• Single RSA keypair per cluster by default

  • Why: Reduces complexity and key management overhead; users don't need to track multiple key IDs.
  • Consequence: If private key is compromised, all sealed secrets in the cluster are exposed; users must rotate the key and re-encrypt all secrets.

• Controller watches all namespaces by default

  • Why: Simplifies user experience; sealed-secret objects work transparently without namespace-specific configuration.
  • Consequence: Controller requires cluster-scoped permissions; cannot restrict unsealing to specific namespaces without additional tooling.

• Scope binding (namespace/name) optional but recommended

  • Why: Flexibility for users who want to migrate secrets between namespaces or redeploy templates.
  • Consequence: Without scope binding, a sealed secret can be unsealed in any namespace; increases risk if untrusted code runs in other namespaces.

• Does not handle authentication/authorization (relies on Kubernetes RBAC)
• Does not provide secret rotation (only key rotation; secret values are static)
• Does not encrypt etcd at rest (Kubernetes native feature, orthogonal concern)
• Does not support asymmetric secret sharing across clusters (each cluster has its own key)
• Does not provide GUI for sealing secrets (CLI-only tool)

Cluster-specific sealing keys: SealedSecrets are encrypted per cluster (keyed by cluster name or certificate); moving sealed secrets between clusters requires key rotation or re-encryption. No secret recovery without private key: If the controller's private key is lost, sealed secrets cannot be decrypted—backup strategy is critical. x/crypto version sensitivity: golang.org/x/crypto v0.50.0 is pinned; upgrading may affect backward compatibility of sealed data. Kubernetes version coupling: go.mod shows explicit k8s.io dependency; older sealed-secrets versions may not work with newer Kubernetes API versions. No RBAC by default in some installs: controller-norbac.jsonnet is separate; ensure correct variant is deployed for your environment.

• Asymmetric Encryption (RSA) — Sealed-secrets core mechanism uses RSA public/private key pairs; understanding why the public key can encrypt but only the private key can decrypt is essential to grasp the security model
• Kubernetes CustomResourceDefinitions (CRDs) and Controllers — The SealedSecret CRD is watched by the controller reconciliation loop; you need to understand how Kubernetes controllers and CRDs work to modify the controller logic or extend sealed-secrets
• GitOps and Infrastructure-as-Code (IaC) — Sealed-secrets solves the core GitOps problem of storing secrets in version control; understanding GitOps workflows (ArgoCD, Flux) and why secrets can't normally be committed helps motivate the entire project
• Key Rotation and Secret Lifecycle Management — The README mentions sealing key renewal and Secret Rotation sections; understanding key lifecycle (generation, rotation, backup, destruction) is critical for operators running sealed-secrets in production
• Namespace and Scope-based Sealing — Sealed-secrets supports scoping encrypted data to specific namespaces or clusters; this isolation mechanism is a key security feature that requires understanding cluster topology and RBAC
• Reconciliation Loops and Kubernetes Operators — The controller continuously reconciles desired state (SealedSecret manifests) with actual state (decrypted Secrets); understanding the reconciliation pattern is essential for debugging or extending the controller
• Container Image Signing (Cosign) — The .github/workflows/cosign.pub file indicates sealed-secrets uses cosign for signing container images; understanding image signature verification adds a layer of supply-chain security trust

• external-secrets/external-secrets — Ecosystem complement: ExternalSecrets operator integrates with sealed-secrets and can sync them to other secret backends (AWS Secrets Manager, HashiCorp Vault)
• mozilla/sops — Alternative encryption approach for GitOps secrets; SOPS encrypts at rest in Git but doesn't integrate natively with Kubernetes controllers like sealed-secrets does
• argoproj/argo-cd — Common companion tool: ArgoCD users typically deploy sealed-secrets to securely manage encrypted manifests in their Git repositories
• fluxcd/flux2 — GitOps ecosystem integration: Flux v2 works seamlessly with sealed-secrets for encrypted secret management in declarative deployments
• kubernetes/kubernetes — Upstream Kubernetes project; sealed-secrets extends Kubernetes' native Secret API with encryption layer not available by default

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add integration tests for kubeseal CLI across multiple Kubernetes versions

The repo has cmd/kubeseal/main_test.go but lacks comprehensive integration tests that verify kubeseal works correctly with different K8s API versions (currently testing against v0.35.4). Given that sealed-secrets is a critical security tool, integration tests validating seal/unseal workflows, error handling, and backward compatibility across K8s versions would significantly improve reliability. This is particularly important since the k8s dependencies show recent version bumps.

• [ ] Create tests/integration directory for integration test suite
• [ ] Add test fixtures in tests/integration/fixtures/ for various SealedSecret manifests
• [ ] Implement tests in tests/integration/kubeseal_test.go covering: seal operation, unseal verification, key rotation scenarios, and namespace isolation
• [ ] Update .github/workflows/ci.yml to run integration tests against multiple K8s versions using kind or kubetest
• [ ] Document integration test setup in docs/developer/testing.md

Add comprehensive prometheus metrics tests for controller monitoring

The repo includes contrib/prometheus-mixin with alerts and dashboards, but cmd/controller/main_test.go likely lacks thorough testing of prometheus metrics emission. With prometheus/client_golang v1.23.2 as a dependency and monitoring-as-code files present, adding tests that verify metrics are correctly labeled, scraped, and match dashboard/alert expectations would ensure observability reliability. This prevents silent monitoring failures in production.

• [ ] Create tests/prometheus_metrics_test.go with testMetricsEmitted() function
• [ ] Add test cases validating controller emits expected metrics: sealing_operations_total, unsealing_errors_total, key_rotation_duration_seconds
• [ ] Verify metric labels match those used in contrib/prometheus-mixin/dashboards/sealed-secrets-controller.json
• [ ] Add validation that metric types (counter/gauge/histogram) align with contrib/prometheus-mixin/rules/rules.libsonnet
• [ ] Document expected metrics in docs/developer/metrics.md

Add end-to-end Helm chart validation workflow in CI

The repo has helm-release.yaml and helm-vib.yaml workflows but lacks a dedicated pre-merge validation for the Helm chart. With carvel/package.yaml and .github/workflows/helm-release.yaml present, adding a GitHub Action that runs 'helm lint', 'helm template', and deploys to a test K8s cluster (via kind) would catch chart syntax errors and breaking changes early. This is critical since users install via Helm.

• [ ] Create .github/workflows/helm-validate.yml that runs on every PR touching helm/ or carvel/ directories
• [ ] Add helm lint validation against the chart in helm/sealed-secrets/ directory
• [ ] Add 'helm template' rendering test to verify all templates generate valid YAML for different value combinations
• [ ] Implement kind cluster deployment test: install chart, verify controller pod runs, test basic seal/unseal operation
• [ ] Add documentation in docs/developer/helm-development.md with chart development guidelines

• Add integration tests for the kubeseal CLI's raw mode (--raw flag) by creating test fixtures in cmd/kubeseal/ directory; verify round-trip encryption/decryption matches the feature described in README but not yet fully covered by tests
• Enhance Prometheus alerts in contrib/prometheus-mixin/alerts/sealed-secrets-alerts.libsonnet by adding a new alert for 'SealingKeyRotationOverdue' to warn when key renewal hasn't occurred within the documented rotation window
• Document the sealing key backup and recovery procedure in a new SECURITY.md section with step-by-step kubectl commands, since SECURITY.md exists but key rotation/recovery isn't explicitly covered with runnable examples

The sealed-secrets project demonstrates reasonable security practices as a cryptographic Kubernetes controller, but has some notable concerns: an invalid/incorrect Go version specification, outdated YAML parsing library (v2 instead of v3), and an incompatible dependency version. The project appropriately has a SECURITY.md file, though it appears incomplete. The main security posture is solid for a crypto-focused tool, but dependency management needs attention. No hardcoded secrets, SQL injection risks, or XSS vulnerabilities are evident from the file structure. The incomplete go.mod file prevents full transitive dependency analysis.

• Medium · Outdated Go Version — go.mod. The go.mod file specifies 'go 1.26.2' which is not a valid Go version (Go versions don't go beyond 1.21 in current releases). This suggests either a typo or incorrect version specification that could lead to build inconsistencies and potential security issues if the actual Go version used is significantly older than intended. Fix: Verify and correct the Go version to a valid, currently supported version (e.g., 1.21 or 1.22). Ensure the version matches the project's actual build requirements and is regularly updated to receive security patches.
• Medium · YAML Dependency with Known Vulnerabilities — go.mod. The project uses 'gopkg.in/yaml.v2 v2.4.0' which is an older version of the YAML parsing library. yaml.v2 has known security issues and the maintainers recommend migrating to yaml.v3. This could potentially expose the application to YAML parsing attacks. Fix: Upgrade to 'gopkg.in/yaml.v3' which includes security fixes and improvements. Audit code for YAML unmarshaling of untrusted input.
• Medium · Dependency on Incompatible Package Version — go.mod. The project includes 'github.com/throttled/throttled v2.2.5+incompatible' which is marked as incompatible, indicating potential API or compatibility issues. Incompatible versions may contain unresolved security issues. Fix: Investigate why this incompatible version is required. Either upgrade to a compatible version or replace with an actively maintained alternative for rate limiting.
• Low · Missing Security Policy Documentation — SECURITY.md. While SECURITY.md exists, the provided snippet is incomplete and cuts off mid-sentence at the vulnerability disclosure process. This could leave users unclear about the complete security process and responsible disclosure timeline. Fix: Complete and fully document the security policy including: response timelines, supported versions with clear EOL dates, contact information for security reports, and the complete disclosure process.
• Low · Potential Cryptographic Implementation Risks — cmd/controller/main.go, cmd/kubeseal/main.go, golang.org/x/crypto dependency. The project implements cryptographic sealing of Kubernetes secrets. The dependency on 'golang.org/x/crypto v0.50.0' is present, but the crypto implementation details in cmd/controller and cmd/kubeseal are not visible in the provided file structure. Custom crypto implementations pose risks. Fix: Ensure all cryptographic operations use only well-vetted, standard library functions from golang.org/x/crypto. Conduct security audit of custom crypto code. Use strong key derivation functions and appropriate cipher modes (GCM recommended).
• Low · Incomplete Dependencies Listed — go.mod (partial file provided). The go.mod snippet appears truncated (ending with 'github.com/mitchellh/reflectwalk v1.0.2 // indir'). Complete dependency analysis cannot be performed without the full file, which could hide vulnerable transitive dependencies. Fix: Review the complete go.mod and go.sum files. Use 'go list -json -m all' to audit all dependencies. Consider using 'go mod graph' to identify transitive dependencies that may have known vulnerabilities.
