"OpenPubkey: OIDC-Backed SSH and Workload Identity Without PKI Pain"
SSH still runs the world, yet most organizations pay an ongoing "PKI tax" in the form of long-lived keys, brittle rotation, and sprawling authorized_keys files that quietly outlive teams and incidents. This book is written for experienced security engineers, platform/SRE leaders, and identity-minded builders who want to replace key distribution and homegrown SSH PKI with something simpler: short-lived, identity-backed access rooted in an existing OIDC provider.
You'll learn the exact invariants that make OIDC and JWT verification safe in production-issuer and audience pinning, JWKS discovery, caching and rotation strategies, clock skew, and failure handling-and how CLI login flows (browser callbacks, device flow, refresh behavior) shape both UX and threat surface. From there, the book dives into the OpenPubkey protocol itself: PK Tokens, what they prove, how identity is bound to a public key, and the strict division of responsibilities between client and verifier. Finally, it applies these primitives to opkssh, walking end-to-end from OIDC login to an SSH session, then into real-world authorization policy, identity-to-Unix mapping, and threat modeling for replay, misconfiguration, and provider hazards-plus workload identity for secretless automation and artifact trust.
Readers should be comfortable with SSH operations and security basics; OIDC is taught from a builder's perspective with verifier-grade rigor. The focus is practical and operational: hardening checklists, rollout/rollback tactics, and vers
