# Configure the daemon for SSL

Complete the following to configure the AEL daemon for SSL:

1. Navigate to the `adaptive-execution/config/application.properties` file and open it with a text editor.
2. Set the values for your environment as in the following table:

| Parameter                      | Value                                                                                                                                     |
| ------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------- |
| **websocketURL**               | The fully-qualified domain name of the node where the AEL daemon is installed. For example,`websocketURL=wss://localhost:${ael.ssl.port}` |
| **ael.ssl.enabled**            | `true`                                                                                                                                    |
| **ael.ssl.key-store**          | `/users/myusername/pentaho/mycertificate.p12`                                                                                             |
| **ael.ssl.key-store-type**     | `PKCS12`                                                                                                                                  |
| **ael.ssl.key-store-password** | The SSL keystore password. This must be set to your keystore password.                                                                    |
| **ael.ssl.key-password**       | The SSL key password. This must be set to your key password.                                                                              |

You can now test your AEL configuration by creating a run configuration using the Spark engine. See \*\*Run configurtaions\*\* in the \*\*Pentaho Data Integration\*\* document for instructions.

The first time you start the AEL daemon, it will prompt you to enter the SSL keystore and key passwords.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/set-up-the-adaptive-execution-layer-ael/advanced-topics/configuring-ael-with-spark-in-a-secure-cluster/using-ssl-encryption/configure-the-daemon-for-ssl.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
