tDataUnmasking

Unmasks data masked with the tDataMasking component to retrieve the original data.

This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.

For more technologies supported by Talend, see Talend components.

The tDataUnmasking component can only unmask data masked with the tDataMasking component, using the FF1 with AES or FF1 with SHA-2 method combined with a user-defined password.

In local mode, Apache Spark 2.4.0 and later versions are supported.

For each column to unmask from the input data, select the unmasking function that corresponds to the related data masking function in the tDataMasking component.
