# tPatternUnmasking

Unmasks data masked with the tPatternMasking 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](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/install-features-to-talend-studio).

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

For each column to unmask from the input data, select the value from the Field type list, and enter the Values, Path, Range and Date Range values set when the input data was masked using tPatternMasking.

In local mode, Apache Spark 3.0.x and later versions are supported.
