[Stackoverflow] How to encode password with HAMC-SHA512 in Spring Boot Security


// easily construct
PasswordEncoder passwordEncoder =
    PasswordEncoderFactories.createDelegatingPasswordEncoder();

// custom instance
String idForEncode = "bcrypt";
Map encoders = new HashMap<>();
encoders.put(idForEncode, new BCryptPasswordEncoder());
encoders.put("noop", NoOpPasswordEncoder.getInstance());
encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
encoders.put("scrypt", new SCryptPasswordEncoder());
encoders.put("sha256", new StandardPasswordEncoder());

PasswordEncoder passwordEncoder =
    new DelegatingPasswordEncoder(idForEncode, encoders);

TroubleShooting

There is no PasswordEncoder mapped for the id “null” : password로 들어온 String의 id 가 없는 것

예를 들어 {noop}abcd1234!@ 이런 식으로 들어와야 하는데 abcd1234!@ 이렇게 들어와서 해당 에러 발생
