enabling-cmek-encryption

A guide to using customer-managed encryption keys, which are encryption keys kept and controlled in your own cloud provider's key-management service. It applies to eligible CockroachDB Cloud Advanced clusters with the Advanced Security Add-on.

In plain words
What is it for?
Use it to enable or verify CMEK, rotate keys, understand plan and cloud-provider requirements, or address an audit finding about encrypting stored data.
Why use it?
It helps organizations meet rules that require control over encryption keys, including key rotation and revocation, and helps verify that the setup is correct.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

enabling-cmek-encryption scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Enabling CMEK Encryption

Enables Customer-Managed Encryption Keys (CMEK) on CockroachDB Cloud clusters so that data-at-rest encryption is controlled by keys in the organization's own cloud provider KMS (AWS KMS, GCP Cloud KMS, or Azure Key Vault). CMEK gives organizations full control over key lifecycle, rotation, and revocation.

When to Use This Skill

  • Enabling CMEK for regulatory or compliance requirements (SOC 2, HIPAA, PCI DSS)
  • Verifying CMEK is properly configured after initial setup
  • Rotating CMEK keys per organization key rotation policy
  • Responding to a security audit finding about encryption at rest
  • Understanding CMEK requirements and plan prerequisites

Prerequisites

  • CockroachDB Cloud Advanced plan — CMEK is not available on Basic or Standard plans
  • Advanced Security Add-on — Must be enabled on the Advanced plan cluster
  • Cloud provider KMS:
    • AWS: KMS key in the same region as the cluster, with appropriate IAM policy
    • GCP: Cloud KMS key ring and key in the same region, with appropriate IAM bindings
    • Azure: Key Vault with key in the same region, with appropriate access policies
  • ccloud CLI authenticated with Cluster Admin role
  • Cross-account access: The CockroachDB Cloud service account must have permission to use the KMS key

Check plan eligibility:

# Verify cluster plan type
ccloud cluster info <cluster-name> -o json
# Look for "plan": "ADVANCED" and Advanced Security Add-on status

Configuration Decisions

Before proceeding, determine which cloud provider KMS the user will use. Ask which option applies to their environment, then follow only the corresponding subsection in Step 2.

Decision 1 — Cloud provider KMS:

  • AWS KMS: Use when the CockroachDB Cloud cluster runs on AWS. Requires a symmetric encryption key in the same region as the cluster.
  • GCP Cloud KMS: Use when the cluster runs on GCP. Requires a key ring and key in the same region.
  • Azure Key Vault: Use when the cluster runs on Azure. Requires a Key Vault with a key in the same region.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
