Answer 1

You can use Bcrypt hashing instead of encyption. Check differece between hashing and encryption link

1. You need to create bean of BcryptPasswordEncoder

   @Bean BCryptPasswordEncoder bCryptPasswordEncoder() { return new BCryptPasswordEncoder(); }

2. Now autowire the bcrypt bean

   @Autowired private BCryptPasswordEncoder bCryptPasswordEncoder;

3. Use the bcryptencoder to ecode the password before saving to database

   User user = new User(); user.setUserName("username"); user.setPassword(bCryptPasswordEncoder.encode("userpassword"));

So the, overall code

//class that handles saving/registering
public class UserRegister{

        @Autowired
        private BCryptPasswordEncoder bCryptPasswordEncoder;

        @Autowired
        private userRepository userRepository; 

        public void register() {
            User user = new User();
            user.se`enter code here`tUserName("username");
            //encodes the password
            user.setPassword(bCryptPasswordEncoder.encode("userpassword"));
            //saves to database
            userRepository.save(user);
        }

}
