Middle masking of email address without configuring delimiter

In this post under DataMask, I will show with example how to do middle masking of email address including delimiter.

So if the text is “john.doe@gmail.com”, the output should be “jo****oe@gmail.com”. The delimiter “.” is also masked.

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 Example10 {
    public static void main(String[] args) throws DataMaskException {
        MaskInformationDTO maskInformationDTO = MaskInformationDTO.builder()
                .maskType(MaskType.MIDDLE_MASKING)
                .leftCharacterCount(2)
                .rightCharacterCount(2)
                .dataFormatType(DataFormatType.EMAIL).build();
        DataMaskManager dataMaskManager = new DataMaskManager();
        String result = dataMaskManager.maskText(maskInformationDTO, "john.doe@gmail.com");
        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 an email address.

I configured it to do middle mask, excluding 2 characters from the left and 2 characters from the right using “leftCharacterCount” and “rightCharacterCount” methods.

At line 17, I create an instance of “DataMaskManager”.

At line 18, I call “maskText” method of “DataMaskManager” and pass the actual email address and instance of “MaskInformationDTO” as arguments.

At line 19, the result is printed to console.

Below is the output

Output

jo****oe@gmail.com
