Encoded password does not look like BCrypt

Question

I am using Spring Boot, Spring Security, OAuth2 and JWT to authenticate my application, but I keep getting this nasty error and I don\'t have any idea what is wrong. My

Answer 1

I struggled with this error while doing a Spring Security Course.

My problem was that even though in the AuthenticationManager I was using the encoding, e.g:

    @Autowired
    public void configureGlobal(final AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
                .passwordEncoder(passwordEncoder());
    }

The Problem was that I was not Encoding the Password when I was saving the Users!! Example:

final Principal entity = new Principal(loginName, passwordEncoder.encode(pass), roles);
