PasswordGenerator helps in generating password using given policy. Consider the following policy:

• Length of password should be 8 characters.

• A password should contains each of the following: upper, lower, digit and a symbol.

Example

The below example shows the generation of a password against above policy using Passay library.

import org.passay.CharacterRule;
import org.passay.EnglishCharacterData;
import org.passay.PasswordGenerator;

public class PassayExample {
   public static void main(String[] args) {
      CharacterRule alphabets = new CharacterRule(EnglishCharacterData.Alphabetical);
      CharacterRule digits = new CharacterRule(EnglishCharacterData.Digit);
      CharacterRule special = new CharacterRule(EnglishCharacterData.Special);

      PasswordGenerator passwordGenerator = new PasswordGenerator();
      String password = passwordGenerator.generatePassword(8, alphabets, digits, special);
      System.out.println(password);
   }
}
