Once you have established your encryption policies and all your data is encrypted, you need to perform some policy maintenance. Periodically, your encryption policies should be updated with a new key. A new key keeps the encryption cipher the same, but provides new input to the cipher algorithm.

Encryption policies are rekeyed in several ways. See one of the following sections for more information:

You can also view the history of an encryption policy. See View encryption policy history in Data Admin for instructions.
