How to use new PasswordEncoder from Spring Security

If you haven’t actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It’s a lot less hassle, as you don’t have to worry about salt at all – the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it’s also a standard which is compatible with applications using other languages.

There’s really no reason to choose any of the other options for a new application.
