ssl-tls-management

ssl-tls-management is a skill for Claude Code, Codex from BagelHole/DevOps-Security-Agent-Skills. It costs 35 tokens per session (3,493 once invoked), scanned B, original, MIT.

A guide for managing SSL/TLS certificates, the files that let websites and services use encrypted HTTPS connections. It covers public certificates from Let’s Encrypt and certificates for internal services.

In plain words
What is it for?
Use it to issue and renew certificates, configure HTTPS, set secure TLS versions and cipher suites, and deploy certificate management in Kubernetes.
Why use it?
It helps prevent expired certificates, weak encryption settings, and broken trust between services.

    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

ssl-tls-management scanned grade B with 1 finding 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 9d 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.

SSL/TLS Management

Manage certificates and secure communications across web servers, Kubernetes clusters, and internal services.

When to Use This Skill

Use this skill when:

  • Setting up HTTPS for a new web application
  • Automating certificate renewal with Let's Encrypt
  • Deploying cert-manager in Kubernetes
  • Configuring TLS for internal service-to-service communication
  • Auditing cipher suites and TLS versions for compliance
  • Responding to an expiring or compromised certificate

Prerequisites

  • Domain name with DNS control for public certificates
  • Root/sudo access on web servers
  • certbot installed for Let's Encrypt
  • openssl CLI available (installed by default on most Linux distros)
  • Kubernetes cluster with Helm for cert-manager deployment
  • Understanding of X.509 certificate chain of trust

Let's Encrypt with Certbot

Installation and Certificate Issuance

# Install certbot (Ubuntu/Debian)
apt update && apt install -y certbot python3-certbot-nginx

# Obtain certificate for nginx (interactive)
certbot --nginx -d example.com -d www.example.com

# Non-interactive mode for automation
certbot certonly --nginx \
  -d example.com \
  -d www.example.com \
  --non-interactive \
  --agree-tos \
  --email [email protected]

# Standalone mode (when no web server is running)
certbot certonly --standalone \
  -d example.com \
  --preferred-challenges http

# DNS challenge (for wildcard certs)
certbot certonly --manual \
  --preferred-challenges dns \
  -d "*.example.com" \
  -d example.com

# Using DNS plugin for automation (Cloudflare example)
pip install certbot-dns-cloudflare
cat > /etc/letsencrypt/cloudflare.ini << 'EOF'
dns_cloudflare_api_token = YOUR_CLOUDFLARE_API_TOKEN
EOF
chmod 600 /etc/letsencrypt/cloudflare.ini

certbot certonly --dns-cloudflare \
  --dns-cloudflare-credentials /etc/letsencrypt/cloudflare.ini \
  -d "*.example.com" \
  -d example.com

Renewal Automation
