DictionarySubstringRule allows to check if certain words are not part of a password. Consider the following example.
Example
import org.passay.DictionarySubstringRule; import org.passay.PasswordData; import org.passay.PasswordValidator; import org.passay.RuleResult; import org.passay.dictionary.ArrayWordList; import org.passay.dictionary.WordListDictionary; public class PassayExample { public static void main(String[] args) { WordListDictionary wordListDictionary = new WordListDictionary( new ArrayWordList(new String[] { "password", "username" })); DictionarySubstringRule dictionaryRule = new DictionarySubstringRule(wordListDictionary); PasswordValidator validator = new PasswordValidator(dictionaryRule); PasswordData password = new PasswordData("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
Invalid Password: [Password contains the dictionary word ''password''.]
