In this post under DataMask, I will show with example how to do middle masking of delimited text including masking of delimiter.
So if the text is “1111-2222-3333-4444”, the output should be “111**********3-4444”. The delimiter “-” is also masked, it is not excluded.
Below is the complete main class
Main class
package core;import io.github.freewarelabs.datamask.core.DataFormatType;import io.github.freewarelabs.datamask.core.DataMaskManager;import io.github.freewarelabs.datamask.core.MaskInformationDTO;import io.github.freewarelabs.datamask.core.MaskType;import io.github.freewarelabs.datamask.core.exception.DataMaskException;public class Example13 { public static void main(String[] args) throws DataMaskException { MaskInformationDTO maskInformationDTO = MaskInformationDTO.builder() .maskType(MaskType.MIDDLE_MASKING) .leftCharacterCount(3) .rightCharacterCount(6) .dataFormatType(DataFormatType.TEXT).build(); DataMaskManager dataMaskManager = new DataMaskManager(); String result = dataMaskManager.maskText(maskInformationDTO, "1111-2222-3333-4444"); System.out.println(result); }}
In the above code, at line 11, I created an instance of MaskInformationDTO class and configured it do middle masking of a text including delimiter “-“.
At line 16, I create an instance of “DataMaskManager”.
At line 17, I call “maskText” method of “DataMaskManager” and pass the actual text and instance of “MaskInformationDTO” as arguments.
At line 18, the result is printed to console.
Below is the output
Output
111**********3-4444
