Spring Security simulataneous usage of multiple PasswordEncoders - encoding

Question

I have spring app with simple configuration of Spring Security using bcrypt (default parameters) and the test works fine, however i want to plan that this application gives the ability to the administrator or the user to change password and select authentication parameters to be used such as:
1)bcrypt (BCryptPasswordEncoder)
2)hash function such as sha (StandardPasswordEncoder),
So the question is how to change the following class (or the AuthenticationManagerBuilder specifically ) in order to reflect that some users could have they password stored as a sha hash but other as bcrypt, Taking into account that the database table already have a column that specify what kind of hash is being stored in the password column i.e. bcrypt or sha.
#Configuration
#EnableWebMvcSecurity
#EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService iUserDetailsService;
#Override
protected void configure(HttpSecurity http) throws Exception {
http
// .csrf().disable()
// .headers().disable()
.headers()
.contentTypeOptions()
.xssProtection()
.cacheControl()
.httpStrictTransportSecurity()
.frameOptions()
.addHeaderWriter(new StaticHeadersWriter("X-Content-Security-Policy","script-src 'self"))
.addHeaderWriter(new StaticHeadersWriter("Content-Security-Policy","script-src 'self'"))
.addHeaderWriter(new StaticHeadersWriter("X-WebKit-CSP","default-src 'self'"))
.and()
.exceptionHandling()
.accessDeniedHandler(syncAccessDeniedHandler())
.and()
.authorizeRequests()
.antMatchers( "/register",
"/static/**",

.permitAll();
}
#Autowired
public void registerAuthentication(AuthenticationManagerBuilder auth) throws Exception {

.userDetailsService(iUserDetailsService).passwordEncoder(pwEncoder());
}

return new BCryptPasswordEncoder();
}
#Bean
public SyncAccessDeniedHandler syncAccessDeniedHandler() {
String uri = "/403";

}

maybe you can use DelegatingPasswordEncoder from spring 5.0 or extend it to create your own version.
