 Red Hat Enterprise Linux Bring-Your-Own-Subscription Gold Images can be secured through the use of [Azure Disk Encryption](../../linux/disk-encryption-overview.md). However, the subscription **must** be registered before enabling encryption.  Details on registering a RHEL BYOS Gold Image are available on the Red Hat site. See [How to register and subscribe a system to the Red Hat Customer Portal using Red Hat Subscription-Manager](https://access.redhat.com/solutions/253273); if you have an active Red Hat subscription, you can also read [Creating Red Hat Customer Portal Activation Keys](https://access.redhat.com/articles/1378093).

 Note that encryption will fail on a [Red Hat custom image](/linux/redhat-create-upload-vhd) that significantly deviates from the base image.
 
 ## Additional information

-- If you create a snapshot from the RHEL BYOS image AND publish the image in [Shared Image Gallery](https://docs.microsoft.com/azure/virtual-machines/linux/shared-image-galleries), you must provide plan information that matches the original source of the snapshot. For example, the command might look like (note the plan parameters in the final line):
+- If you create a snapshot from the RHEL BYOS image and publish a custom image in [Shared Image Gallery](https://docs.microsoft.com/azure/virtual-machines/linux/shared-image-galleries), you must provide plan information that matches the original source of the snapshot. For example, the command might look like this:
 
     ```azurecli

+    [Azure Disk Encryption](#encrypt-red-hat-enterprise-linux-bring-your-own-subscription-gold-images) is not supported on custom images.
 
 - If you are using automation to provision VMs from the RHEL BYOS images, you must provide plan parameters similar to what was shown above. For example, if you are using Terraform, you would provide the plan information in a [plan block](https://www.terraform.io/docs/providers/azurerm/r/virtual_machine.html#plan).
