TLS Certificates

The Call of the Wildcard Certificate

TLS administration for teams who have heard something howling in production

Jack London · 5 July 2026

The pack survives because somebody automated renewal.

Jack London tells a bracing tale of certificate lifecycles, renewal automation, trust chains, and the particular shame of discovering an unmanaged wildcard in front of customers. It favours ACME, inventory, and short-lived credentials over heroic calendar reminders.

Contents

  1. Into the Trust Store
  2. The Law of Common Names
  3. Renewal by Fang and Cron
  4. Revocation in the Snow

Published by Austenpunk, the distinguished imprint for engineers who believe that every production incident would be improved by a stronger sense of narrative irony.

This essential volume combines literary feeling, technical anxiety, and just enough documentation to suggest that somebody once understood the system.
