Revoking Your TDE Master Encryption Key

You can stop service access and shut down the system by revoking the TDE master encryption key. Application data and the related service will no longer be accessible. You can access the service again only by restoring the revoked key.

To revoke the TDE master encrypted key:

Sign in to Applications Console or Infrastructure Classic Console.
Sign in to the Applications Console if you want to work with Oracle Cloud Applications. Sign in to Infrastructure Classic Console if you want to access Oracle Cloud infrastructure and platform services. If you see Infrastructure Classic at the top of the page when you sign in to Oracle Cloud, then you are using Infrastructure Classic Console and your subscription does not support access to the Infrastructure Console.
In the Cloud Services section, click the Action icon on the service tile to open the Service Details page. The Overview tile is in focus.
Click the Manage TDE Key tile.
Click Choose operation and select Revoke TDE Master Key.
In the Warning window, review the warning message and click Yes to continue. Make note of the TDE master key you are revoking. You’ll need the same key to restore it later.
Click Revoke TDE Master Key.

The key is revoked and data is no longer accessible.

Note:

Make a copy of the revoked key and keep it safe. You must provide the exact key that you revoked when restoring access to data. If you lose the key, data access will be lost.
