# Manage KMS using the GUI

Using the GUI, you can:

* [Configure a KMS](#configure-a-kms)
* [View the KMS configuration](#view-the-kms-configuration)
* [Update the KMS configuration](#update-the-kms-configuration)
* [Remove the KMS configuration](#remove-the-kms-configuration)

## Configure a KMS

Configure the KMS of either HashiCorp Vault or KMIP within the WEKA system to encrypt filesystem keys securely.

**Before you begin**

Ensure that the KMS is preconfigured, and both the key and a valid token are readily available.

**Procedure**

1. From the menu, select **Configure > Cluster Settings**.
2. From the left pane, select **Security**.
3. On the **Security** page, select **Configure KMS**.
4. On the **Configure KMS** dialog, select the KMS type to deploy: **HashiCorp Vault** or **KMIP**.
5. Set the connection properties according to the selected KMS type. Select the relevant tab for details:

{% tabs %}
{% tab title="Hashicorp Vault" %}
For the **HashiCorp Vault** type, set the following:

* **Address**: The KMS address.
* **Key Identifier**: Key name to secure the filesystem keys (encryption-as-a-service).
* **Token**: The authentication API token you obtain from the vault to access the KMS.
* **Namespace:** The namespace name that identifies the logical partition within the vault. It is used to organize and isolate data, policies, and configurations. Namespace names must not end with "/", avoid spaces, and refrain from using reserved names like `root`, `sys`, `audit`, `auth`, `cubbyhole`, and `identity`. (Available from v4.2.7.)

{% endtab %}

{% tab title="KMIP " %}
For the **KMIP** type, set the following:

* **Address**: Hostname and port of the KMS in the format `hostname:port`. Do not include any protocol prefixes such as `https://`. The hostname can be either a fully qualified domain name (FQDN) or an IP address. Port 5696 is the default for KMIP, but this may vary depending on the server configuration.
* **KMS Identifier**: Key UID to secure the filesystem keys (encryption-as-a-service).
* **Client Certificate:** The client certificate content of the PEM file.
* **Client Key**: The client key content of the PEM file.
* **CA Certificate**: (Optional) The CA certificate content of the PEM file.

**Procedure**

1. From the menu, select **Configure > Cluster Settings**.
2. From the left pane, select **Security**.
3. The **Security** page displays the configured KMS.
4. Select **Update KMS**, and update its settings.
5. Select **Save**.

## Remove the KMS configuration

Removing a KMS configuration is possible only if no encrypted filesystems exist.

**Procedure**

1. From the menu, select **Configure > Cluster Settings**.
2. From the left pane, select **Security**.
3. The **Security** page displays the configured KMS.
4. Select **Reset KMS.**
5. In the message that appears, select **Yes** to confirm the KMS configuration reset.
