+garak.generators.websocket
+==========================
+
+WebSocket connector for real-time LLM services.
+
+This generator enables garak to test WebSocket-based LLM services that use 
+real-time bidirectional communication, similar to modern chat applications.
+
+Uses the following options from ``_config.plugins.generators["websocket"]["WebSocketGenerator"]``:
+
+* ``uri`` - the WebSocket URI (ws:// or wss://); can also be passed in --model_name
+* ``name`` - a short name for this service; defaults to "WebSocket LLM"
+* ``auth_type`` - authentication method: "none", "basic", "bearer", or "custom"
+* ``username`` - username for basic authentication
+* ``api_key`` - API key for bearer token auth or password for basic auth
+* ``key_env_var`` - environment variable holding API key; default ``WEBSOCKET_API_KEY``
+* ``req_template`` - string template where ``$INPUT`` is replaced by prompt, ``$KEY`` by API key, ``$CONVERSATION_ID`` by conversation ID
+* ``req_template_json_object`` - request template as Python object, serialized to JSON with placeholder replacements
+* ``headers`` - dict of additional WebSocket headers
+* ``response_json`` - is the response in JSON format? (bool)
+* ``response_json_field`` - which field contains the response text? Supports JSONPath (prefix with ``$``)
+* ``response_after_typing`` - wait for typing indicators to complete? (bool)
+* ``typing_indicator`` - string that indicates typing status; default "typing"
+* ``request_timeout`` - seconds to wait for response; default 20
+* ``connection_timeout`` - seconds to wait for connection; default 10
+* ``max_response_length`` - maximum response length; default 10000
+* ``verify_ssl`` - enforce SSL certificate validation? Default ``True``
+
+Templates work similarly to the REST generator. The ``$INPUT``, ``$KEY``, and 
+``$CONVERSATION_ID`` placeholders are replaced in both string templates and 
+JSON object templates.
+
+JSON Response Extraction
+------------------------
+
+The ``response_json_field`` parameter supports JSONPath-style extraction:
+
+* Simple field: ``"text"`` extracts ``response.text``
+* Nested field: ``"$.data.message"`` extracts ``response.data.message``  
+* Array access: ``"$.messages[0].content"`` extracts first message content
+
+Authentication Methods
+----------------------
+
+**No Authentication:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "ws://localhost:3000/chat",
+            "auth_type": "none"
+         }
+      }
+   }
+
+**Basic Authentication:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "ws://localhost:3000/chat",
+            "auth_type": "basic",
+            "username": "user"
+         }
+      }
+   }
+
+Set the password via environment variable:
+
+.. code-block:: bash
+
+   export WEBSOCKET_API_KEY="your_secure_password"
+
+**Bearer Token:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "wss://api.example.com/llm",
+            "auth_type": "bearer",
+            "api_key": "your_api_key_here"
+         }
+      }
+   }
+
+**Environment Variable API Key:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "wss://api.example.com/llm", 
+            "auth_type": "bearer",
+            "key_env_var": "MY_LLM_API_KEY"
+         }
+      }
+   }
+
+Message Templates
+-----------------
+
+**Simple Text Template:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "ws://localhost:3000/chat",
+            "req_template": "User: $INPUT"
+         }
+      }
+   }
+
+**JSON Object Template:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "ws://localhost:3000/chat",
+            "req_template_json_object": {
+               "message": "$INPUT",
+               "conversation_id": "$CONVERSATION_ID",
+               "api_key": "$KEY"
+            },
+            "response_json": true,
+            "response_json_field": "text"
+         }
+      }
+   }
+
+**Complex JSON with Nested Response:**
+
+.. code-block:: JSON
+
+   {
+      "websocket": {
+         "WebSocketGenerator": {
+            "uri": "wss://api.example.com/llm",
+            "req_template_json_object": {
+               "prompt": "$INPUT",
+               "stream": false,
+               "model": "gpt-4"
+            },
+            "response_json": true,
+            "response_json_field": "$.choices[0].message.content"
+         }
+      }
+   }
+
+Usage Examples
+---------------
+
+**Command Line with JSON Options:**
+
+.. code-block:: bash
+
+   # Set password securely via environment variable
+   export WEBSOCKET_API_KEY="your_secure_password"
+   
+   garak --model_type websocket.WebSocketGenerator \
+         --generator_options '{"websocket": {"WebSocketGenerator": {"uri": "ws://localhost:3000", "auth_type": "basic", "username": "user"}}}' \
+         --probes dan
+
+**Configuration File:**
+
+Save configuration to ``websocket_config.json`` and use:
+
+.. code-block:: bash
+
+   garak --model_type websocket.WebSocketGenerator \
+         -G websocket_config.json \
+         --probes encoding
+
+**Testing with Public Echo Server:**
+
+.. code-block:: bash
+
+   garak --model_type websocket.WebSocketGenerator \
+         --generator_options '{"websocket": {"WebSocketGenerator": {"uri": "wss://echo.websocket.org", "response_after_typing": false}}}' \
+         --probes dan --generations 1
+
+SSH Tunnel Support
+------------------
+
+The generator works seamlessly with SSH tunnels for secure remote testing:
+
+.. code-block:: bash
+
+   # Establish tunnel
+   ssh -L 3000:target-host:3000 jump-host -N -f
+   
+   # Test through tunnel  
+   garak --model_type websocket.WebSocketGenerator \
+         --generator_options '{"websocket": {"WebSocketGenerator": {"uri": "ws://localhost:3000"}}}' \
+         --probes malwaregen
+
+Typing Indicators
+-----------------
+
+Many chat-based LLMs send typing indicators. Configure response handling:
+
+* ``response_after_typing: true`` - Wait for typing to complete (default)
+* ``response_after_typing: false`` - Return first substantial response
+* ``typing_indicator`` - String to detect typing status (default "typing")
+
+This enables proper testing of streaming/real-time LLM services.
