managing-certificates-and-encryption

managing-certificates-and-encryption is a skill for Claude Code, Codex from cockroachlabs/cockroachdb-skills. It costs 108 tokens per session (2,216 once invoked), scanned B, original, Apache-2.0.

A guide for managing TLS certificates and encryption keys in CockroachDB. TLS protects connections between clients and database machines, while encryption keys protect stored data.

In plain words
What is it for?
Use it to monitor or replace certificates in self-hosted deployments, manage customer-controlled encryption keys in supported cloud plans, respond to a key compromise, or review encryption for compliance.
Why use it?
It clarifies which security tasks you must handle yourself and which are managed by CockroachDB, reducing the risk of expired certificates or mishandled keys.

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 B, and why

managing-certificates-and-encryption scanned grade B with 2 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 2mo 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Deploy to node, set `chmod 0600` on key file. CockroachDB auto-detects new certs — no restart required.

Managing Certificates and Encryption

Manages TLS certificate and encryption key lifecycle across all deployment tiers. Before providing procedures, this skill gathers context to determine whether the operator manages certificates directly (Self-Hosted), manages CMEK encryption keys (Advanced/BYOC), or has fully managed encryption (Standard/Basic).

When to Use This Skill

  • Monitoring certificate expiration (Self-Hosted)
  • Performing scheduled certificate rotation (Self-Hosted)
  • Managing CMEK encryption keys (Advanced/BYOC)
  • Responding to key compromise (Self-Hosted, CMEK)
  • Auditing encryption posture for compliance (all tiers)
  • Adding DNS names or IPs to node certificates (Self-Hosted)

For daily health checks: Use reviewing-cluster-health.

Step 1: Gather Context

Required Context

Question Options Why It Matters
Deployment tier? Self-Hosted, Advanced, BYOC, Standard, Basic Determines encryption management responsibility
Reason? Routine monitoring, Scheduled rotation, Key compromise, Compliance audit, Add SAN entries Determines urgency and procedure

Additional Context (by tier)

If Self-Hosted:

Question Options Why It Matters
Certificate type? CA, Node, Client, UI Different rotation procedures per type
Deployment platform? Bare metal/VMs, Kubernetes (Operator/Helm/manual) Changes rotation tooling
Certificate tooling? cockroach cert, openssl, HashiCorp Vault, cert-manager Determines generation commands
Is the CA being rotated? Yes, No CA rotation requires combined CA approach

If Advanced or BYOC:

Question Options Why It Matters
Is this about CMEK? Yes, No CMEK is the customer's encryption responsibility; TLS is managed by CRL
Cloud provider? AWS, GCP, Azure Determines KMS service and CLI commands
CMEK currently enabled? Yes, No CMEK must be enabled at cluster creation

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.
