# KMS Keys DuploCloud allows you to configure Tenant and Plan level KMS (Key Management Service) keys for AWS/Azure resources. These keys can be selected when creating supported resources to ensure consistent encryption and help meet compliance requirements. ## Adding a KMS Key for a Plan Plan-level KMS keys can be used for encrypting resources in any Tenant under the selected Plan. 1. Navigate to **Administrator** -> **Plans**. 2. Select the Plan from the **NAME** column. 3. Select the **KMS** tab. 4. Click **Add**. The **Add a Kms Key** pane displays.

5. Complete the following fields:

Field	User Action / What to Enter
Key Name	Enter a friendly name for the key (e.g., `test-key`)
Key Id	Enter the cloud provider–specific key ID (AWS KMS Key ID or Azure Key Vault Key ID).
Key Arn	Enter the cloud provider–specific key ARN or resource ID. For AWS this is the KMS Key ARN; for Azure, this is the Key Vault Key ID URI.

6. Click **Submit** to add the key to the Plan. Once added, the key can be selected when creating supported resources in the Plan, such as databases, compute instances, storage resources, and other services.

Navigate to the resource creation page (e.g., **Hosts**, **RDS**, or other supported resources). 2. Locate the **Encryption Key** or **KMS Key** field. 3. Choose a key from the options listed under **Default Tenant Key**, **Plan-level Keys**, or **Tenant-level Keys**.
