dsh-plugin-auth-webserver

Features

• DSH-themed web login page
  • Replaces native browser authentication popups with a dark, glassmorphism login interface matching DeepSeek Harness's design system.
  • Bilingual (English / Simplified Chinese, following the browser's language), password show/hide toggle, error animations, Enter-to-submit, responsive on mobile and desktop.
• HMAC cookie sessions and logout
  • Issues 30-day cryptographically signed HMAC session tokens on login.
  • Dedicated /api/auth.logout endpoint and a Web UI logout button.
• Web GUI settings card
  • Live configuration in the DSH Web UI (Settings -> Plugins -> Web authentication).
  • Hot-updates credentials in memory instantly and persists them to a plugin-owned state file under $DSH_HOME/plugins/dsh-plugin-auth-webserver/, so they survive restarts without touching your config layers.
• Dual-mode authentication and WebSocket protection
  • Prefers web form / cookie sessions while staying backward-compatible with HTTP Basic Auth for CLI tools, curl, and automated API clients.
  • Full authentication coverage for both HTTP routes and WebSocket (upgrade) channels.
• Remote IP privileged RPC trust delegation
  • Normalizes request Host and Origin headers for authenticated sessions, eliminating HTTP 403 errors when accessing privileged RPC endpoints via a public IP.
• Web Crypto UUID auto-polyfill
  • Injects a safe UUID generator into the HTML <head> for non-HTTPS and direct-IP environments, preventing client-side crashes.

Installation

Install the bundle into a profile with dsh plugin:

# From a git host (pin a commit so later pushes cannot change what runs):
dsh plugin --profile web add github:kolawong/dsh-plugin-auth-webserver#<commit-sha>

# Or from a tarball / npm registry once published:
dsh plugin --profile web add ./dsh-plugin-auth-webserver-0.3.0.tgz
dsh plugin --profile web add dsh-plugin-auth-webserver

The package declares dsh.bundle, so dsh plugin appends it to the
profile's bundle list automatically; its patch disables the stock
webserver row and inserts the auth-gated server. Then boot:

dsh --profile web

Open http://your-server-ip:3080 to see the login page.

Configuration

Every option has a default; override the webserver-auth row in your
profile's own patch ($DSH_HOME/profiles/web/cordis.patch.yml), which is
applied after every bundle layer:

- id: webserver-auth
  config:
    host: '0.0.0.0'
    port: 3080
    username: 'admin'
    password: 'your_secure_password'

Changes made in the Web UI settings card apply immediately and are stored
in $DSH_HOME/plugins/dsh-plugin-auth-webserver/state.json (mode 0600).
Environment variables DSH_AUTH_USER and DSH_AUTH_PASS override both the
config and the saved state.

API endpoints

• POST /api/auth.login — Authenticate and receive a session cookie ({ username, password }).
• POST /api/auth.logout — Invalidate the current session and clear the cookie.
• GET /api/auth.get — Retrieve the current username, password, and realm (requires authentication).
• POST /api/auth.update — Live-update credentials and persist them (requires authentication).
