Passay - HistoryRule

HistoryRule allows to check if given password has not been in use in near past. Consider the following example.

Example

import org.passay.HistoryRule;
import org.passay.PasswordData;
import org.passay.PasswordValidator;
import org.passay.RuleResult;
import org.passay.SourceRule;

public class PassayExample {
   public static void main(String[] args) {
      SourceRule sourceRule = new SourceRule();
      HistoryRule historyRule = new HistoryRule();
      PasswordValidator validator = new PasswordValidator(sourceRule, historyRule);
      PasswordData password = new PasswordData("password@123");
      password.setPasswordReferences(
         new PasswordData.SourceReference("source", "password"), 
         new PasswordData.HistoricalReference("password@123")
      );
      RuleResult result = validator.validate(password);

      if(result.isValid()){
         System.out.println("Password validated.");
      }else{
         System.out.println("Invalid Password: " + validator.getMessages(result));            
      }
   }
}

Output
