works well. See

Edition.
For information about configuring and using BlueScale Encryption
Standard Edition, see the remainder of this chapter.
BlueScale Professional Edition For sites that want to implement
compression along with greater flexibility and security, to protect data
wherever it's stored and regardless of the retention period, BlueScale
Encryption Professional Edition works well.
The Professional Edition of BlueScale Encryption lets you choose whether
to support one encryption password, or three encryption passwords that
enforce another level of security.
For information about installing, configuring, and using BlueScale
Encryption Professional Edition, see the Spectra BlueScale Encryption User
Guide.
