10.2. Encryption Ciphers

The encryption cipher is configurable on a per-attribute basis and must be selected by the administrator at the time encryption is enabled for an attribute. Configuration can be done through the Console or through the command line.
The following ciphers are supported:
  • Advanced Encryption Standard (AES)
  • Triple Data Encryption Standard (3DES)

Note

For strong encryption, Red Hat recommends using only AES ciphers.
All ciphers are used in Cipher Block Chaining mode.
Once the encryption cipher is set, it should not be changed without exporting and re-importing the data.
