It lets administrators authorize identities such as email addresses and groups instead of distributing long-lived SSH public keys, while still using the stock SSH client and server protocol. ### Historique du projet The tool is built on OpenPubkey, a protocol described in a 2023 IACR paper that binds a user-held public key into an OpenID Connect ID Token, turning that token into what the authors call a PK Token. opkssh applies that idea to SSH by generating an SSH key/certificate carrying the PK Token and by configuring sshd to verify it. Cloudflare announced on 2025-03-25 that it had open-sourced OPKSSH under the OpenPubkey project. The announcement says the OpenPubkey protocol became an open source Linux Foundation project in 2023, while OPKSSH had remained closed source under BastionZero, later Cloudflare, until the donation. ### Historique d'adoption The project moved quickly into normal package-manager territory for a security tool: its metadata lists packages for Homebrew, Debian development packages, Fedora, Nix, and Windows winget, and the README documents Homebrew, winget, Chocolatey, Nix, and direct binary installs. ### Modes d'utilisation A user runs `opkssh login`, authenticates in a browser with an OpenID Provider, and receives a generated SSH key whose public side contains the OpenPubkey token. On the server, opkssh is used through sshd's `AuthorizedKeysCommand` hook, so the verifier can extract the PK Token, validate the identity provider signature and expiry, and map the identity to a Unix or Windows account. Operators use `/etc/opk/providers` to choose trusted OpenID Providers and client IDs, and `/etc/opk/auth_id` or per-user equivalents to authorize identities, subjects, or group claims. The design gives SSH administrators an SSO-style access list without changing the SSH wire protocol. ### Pourquoi les passionnés de paquets s'y intéressent opkssh is interesting because it packages an identity-protocol research result as a small CLI that plugs into a decades-old Unix extension point. For package nerds, the notable bit is not a new daemon or a replacement SSH stack, but a cross-platform binary that makes SSH key lifecycle policy distributable through package managers. ### Chronologie - 2023: OpenPubkey is published as a protocol for binding OpenID Connect ID Tokens to user-held public keys. - 2023: OpenPubkey becomes an open source Linux Foundation project, according to Cloudflare's OPKSSH open-source announcement. - 2025-03-25: Cloudflare announces that OPKSSH has been donated to the OpenPubkey project and released as open source. ### Related projects - OpenPubkey is the underlying protocol. OpenSSH supplies the client/server behavior and `AuthorizedKeysCommand` integration point. The broader ecosystem includes OpenID Providers such as Google, Microsoft Entra ID, GitLab, Keycloak, Authentik, Authelia, Zitadel, and similar OIDC services. ### Sources - - - - ## Notes de sécurité broad file, network, media, or database tool signal. - **Risque Geiger:** blue / moyen - broad file, network, media, or database tool signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
