Passay - AllowedCharacterRule
AllowedCharacterRule allows to specify the characters which a password can include. Consider the following example.
Example
The below example shows the validation of a password against above policy using Passay library.
import org.passay.AllowedCharacterRule; import org.passay.LengthRule; import org.passay.PasswordData; import org.passay.PasswordValidator; import org.passay.Rule; import org.passay.RuleResult; public class PassayExample { public static void main(String[] args) { //Rule: Password should contains only a, b and c Rule rule1 = new AllowedCharacterRule(new char[] {'a', 'b', 'c'}); //8 and 16 characters Rule rule2 = new LengthRule(8, 16); PasswordValidator validator = new PasswordValidator(rule1, rule2); PasswordData password = new PasswordData("abcabcab1"); 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 illegal character '1'.]
