# Node Storage and Retrieval
|
|
|
|
## Properties
|
|
|
|
### Encrypted properties (```d:encrypted```)
|
|
Encrypted properties are stored as BLOBs in the database, but there is no additional handling for
|
|
them. In particular, the ```NodeService``` does not encrypt or decrypt them. It only guarantees
|
|
that properties of this type contain objects of type ```javax.crypto.SealedObject```. It is up to
|
|
the implementor of a custom extension to handle encryption.
|
|
The ACS provides the helper class ```MetadataEncryptor``` which provides key handling and a one-stop-shop
|
|
for encryption. But custom implementations do not need to use it.
