Add documentation for all user/operator-facing changes introduced by the security review branch: rate limits, security headers, webhook HMAC verification, payload size limits, gateway token redaction, non-root containers, agent token logging, and prompt injection mitigation. Updated: docs/reference/api.md, docs/reference/authentication.md, docs/reference/configuration.md, docs/deployment/README.md, docs/operations/README.md, docs/openclaw_gateway_ws.md, backend/README.md. Created: docs/reference/security.md (consolidated security reference). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Gateway WebSocket protocol
Connection Types
OpenClaw Mission Control supports both secure (wss://) and non-secure (ws://) WebSocket connections to gateways.
Secure Connections (wss://)
For production environments, always use wss:// (WebSocket Secure) connections with valid TLS certificates.
Self-Signed Certificates
You can enable support for self-signed TLS certificates with a toggle:
- Navigate to the gateway configuration page (Settings → Gateways)
- When creating or editing a gateway, enable: "Allow self-signed TLS certificates"
- This applies to any
wss://gateway URL for that gateway configuration.
When enabled, Mission Control skips TLS certificate verification for that gateway connection.
Security Warning: Enabling this weakens transport security and should only be used when you explicitly trust the endpoint and network path. Prefer valid CA-signed certificates for production gateways.
Configuration Options
When configuring a gateway, you can specify:
- Gateway URL: The WebSocket endpoint (e.g.,
wss://localhost:18789orws://gateway:18789) - Gateway Token: Optional authentication token. For security, tokens are never returned in API responses. The API indicates only whether a token is configured (
has_token: true/false). Store tokens securely at creation time; they cannot be retrieved later. - Workspace Root: The root directory for gateway files (e.g.,
~/.openclaw) - Allow self-signed TLS certificates: Toggle TLS certificate verification off for this gateway's
wss://connections (default: disabled)
