Class EncryptedData

java.lang.Object

org.fuin.ddd4j.ddd.EncryptedData

All Implemented Interfaces:

java.io.Serializable, org.fuin.objects4j.vo.ValueObject

@Immutable
public final class EncryptedData
extends java.lang.Object
implements org.fuin.objects4j.vo.ValueObject, java.io.Serializable

Container for encrypted data. In addition to the data itself, the container has information about the key used to encrypt the data and the format of the data. The receiving system must have a notion of what the key identifier, versions and data type means. Equals and hash code is based on all data (value object)
