Class IBANMaskSanitizer

java.lang.Object
io.github.rabinarayanpatra.sanitizer.builtin.IBANMaskSanitizer
All Implemented Interfaces:
FieldSanitizer<String>
public class IBANMaskSanitizer extends Object implements FieldSanitizer<String>
Sanitizer that masks an International Bank Account Number (IBAN), preserving only the last four characters.

All whitespace is removed before masking. The result is a masked string of asterisks followed by the last four characters of the IBAN, helping protect sensitive account details while retaining partial traceability. 

 
 String input = "DE89 3704 0044 0532 0130 00";
 String masked = new IBANMaskSanitizer().sanitize(input);
 // "********************3000"
