Performing TDE Key and Password Management

What if someone discovers your TDE keys somehow? You can simply re-create the encrypted values by issuing a simple command. While you are at it, you may also want to choose a different encryption algorithm such as AES256. You can do both by issuing:

    ALTER TABLE accounts REKEY USING 'aes256';

If someone discovers the wallet password, you can change it using a graphical tool called Oracle Wallet Manager. From the command line, type owm, which brings up the tool as shown in Figure 4-8. From the top menu, choose Wallet → Open and choose the wallet location you have specified. You will have to supply the password of the wallet. After that, choose Wallet → Change Password to change the password. Note that changing the password does not change the keys.
