Assigning a New Master Encryption Key

Assign a new key to a Block Volume resource, such as when restoring a backup, cloning a volume, activating a replica, or enabling replication. You can assign a customer-managed key or an Oracle-managed key.

Requirements

Customer-Managed Encryption Keys for Cross-Region Operations

When you specify a customer-managed encryption key for cross-region operations, ensure the following:

If you don't specify a customer-managed encryption key for cross-region operations, an Oracle-managed encryption is used by default. These requirements don't apply to Oracle-managed encryption keys.

Cross-Region Backup Copies

When you manually copy a volume backup between regions you can use the Oracle-managed key or your own encryption key. When you assign a backup policy with cross-region backup copies enabled to a volume or volume group, or perform a manual backup cross region copy, you can optionally select Encrypt using customer-managed keys for Cross region backup copy encryption to encrypt the volume backup in the destination region. If you select this option, you must specify the OCID for a valid encryption key in the destination region.

See also Customer-Managed Encryption Keys for Cross-Region Operations.

    • Restoring a backup, cloning a volume, or activating a replica:

      Under Encryption, select Encrypt using customer-managed keys, and then select the Vault encryption key you want to use.

    • Enabling replication: You can optionally specify your own key to encrypt the volume replica in the destination region. The customer-managed key can be one of the following types of key:
      • A replicated key that exists in the destination region
      • Any key in the target region that you own and is different than the one in the source region

      You can encrypt the volume replica with a customer-managed encryption key in the destination region when you enable replication for a volume or volume group.

      Select Encrypt using customer-managed keys for Cross region replication encryption, and then specify the OCID for a valid encryption key in the region you selected to replicate the volume or volume group to.

      If you don't specify a customer-managed key, an Oracle-managed encryption key is used instead.

    • Restoring a backup, cloning a volume, or activating a replica:

      Use the relevant Block Volume CLI command. Include the --kms-key-id attribute unless, for restoring a volume, you want to use the Oracle-managed key.

    • Enabling replication: You can optionally specify your own key to encrypt the volume replica in the destination region. The customer-managed key can either be:
      • a replicated key that exists in the destination region.
      • any key in target region that you own and is different than the one in the source region.

      You can encrypt the volume replica with a customer-managed encryption key in the destination region when you enable replication for a volume or volume group.

      Select Encrypt using customer-managed keys for Cross region replication encryption, and then specify the OCID for a valid encryption key in the region you selected to replicate the volume or volume group to.

      If you don't specify a customer-managed key, an Oracle-managed encryption key is used instead.

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

    • Restoring a backup, cloning a volume, or activating a replica:

      Run the relevant Core Services API operation to assign a master encryption key. Include the kmsKeyId attribute.

    • Enabling replication: You can optionally specify your own key to encrypt the volume replica in the destination region. The customer-managed key can either be:
      • a replicated key that exists in the destination region.
      • any key in target region that you own and is different than the one in the source region.

      You can encrypt the volume replica with a customer-managed encryption key in the destination region when you enable replication for a volume or volume group.

      Select Encrypt using customer-managed keys for Cross region replication encryption, and then specify the OCID for a valid encryption key in the region you selected to replicate the volume or volume group to.

      If you don't specify a customer-managed key, an Oracle-managed encryption key is used instead.
