## Why The device-key protocol needs an app-server implementation that keeps local key operations behind the same request-processing boundary as other v2 APIs. app-server owns request dispatch, transport policy, documentation, and JSON-RPC error shaping. `codex-device-key` owns key binding, validation, platform provider selection, and signing mechanics. Keeping the adapter thin makes the boundary easier to review and avoids moving local key-management details into thread orchestration code. ## What changed - Added `DeviceKeyApi` as the app-server adapter around `DeviceKeyStore`. - Converted protocol protection policies, payload variants, algorithms, and protection classes to and from the device-key crate types. - Encoded SPKI public keys and DER signatures as base64 protocol fields. - Routed `device/key/create`, `device/key/public`, and `device/key/sign` through `MessageProcessor`. - Rejected remote transports before provider access while allowing local `stdio` and in-process callers to reach the device-key API. - Added stdio, in-process, and websocket tests for device-key validation and transport policy. - Documented the device-key methods in the app-server v2 method list. ## Test coverage - `device_key_create_rejects_empty_account_user_id` - `in_process_allows_device_key_requests_to_reach_device_key_api` - `device_key_methods_are_rejected_over_websocket` ## Stack This is PR 3 of 4 in the device-key app-server stack. It is stacked on #18429. ## Validation - `cargo test -p codex-app-server device_key` - `just fix -p codex-app-server`
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
