# DataEncryption Configuration Parameters

The data encryption section contains settings that determines how IDOL Server encrypts your data.

You turn on data encryption by setting AESKeyFile to the location of an AES key file.

IDOL Server uses 256-bit AES encryption. Encryption includes:

- document data in the index.
- temporary data in the on-disk index cache.
- value mapping files used by the `parametric`, `match`, and `security` indexes.
- the term dictionary.
- the unstemmed term tree.
- the geospatial index.
- any data sent with index actions that is stored in your index queue before processing.

You can determine the encryption status of your index by using the GetStatus action.
