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-webserverThe 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 webOpen 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.
| Option | Type | Default | Description |
|---|---|---|---|
host | string | '0.0.0.0' | Listening interface (0.0.0.0 or 127.0.0.1). |
port | number | 3080 | HTTP/WebSocket listen port. |
username | string | 'admin' | Authentication username. |
password | string | '' | Authentication password (leave empty to disable authentication). |
