Bcrypt自定义密码配置 [英] Bcrypt Custom password configuration

问题描述

我正在更改密码，然后转发到/loginuser并重定向到用户仪表板.自从我是一个初学者以来，我就已经通过httpbasic身份验证来确保这一点，我在休眠状态下使用createNativeSQLQuery并从数据库中获取结果.我是否必须实现任何UserDetailsS​​ervice接口Spring Security?我的目标是仅实现加密密码并将其存储在数据库中.我面临的问题是，我添加了一个Bean配置，例如，

i am changing the password and then forwarding to /loginuser and redirect to users dashboard. i had secured this with httpbasic authentication since i am a beginner, I am using createNativeSQLQuery in hibernate and fetching the results from Database. Did I have to implement any UserDetailsService Interface Spring Security? My goal is to only achieve encrypting password and store it DB. the issue i am facing is, I had added a bean configuration such as,

@Bean
        public PasswordEncoder customPasswordEncoder() {
            return new BCryptPasswordEncoder(){
                @Override
                public String encode(CharSequence rawPassword) {
                    return BCrypt.hashpw(rawPassword.toString(), BCrypt.gensalt(4));
                }
                @Override
                public boolean matches(CharSequence rawPassword, String encodedPassword) {
                    return BCrypt.checkpw(rawPassword.toString(), encodedPassword);
                }
            };
        }

我不知道为什么会抛出此异常.我们应该对盐弹进行硬编码吗?

I don't know why its throwing this exception. should we hard-code the salt rounds?

java.lang.IllegalArgumentException: Invalid salt
    at org.springframework.security.crypto.bcrypt.BCrypt.hashpw(BCrypt.java:552) ~[spring-security-core-5.1.5.RELEASE.jar:5.1.5.RELEASE]

    at com.bootapp.FullTimeEquivalents.config.PasswordEncoderConfig$1.matches(PasswordEncoderConfig.java:29) ~[classes/:na]

推荐答案

@Autowired
    DataSource dataSource;

    @Bean
    public PasswordEncoder passwordEncoder()
    {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.jdbcAuthentication().dataSource(dataSource).passwordEncoder(passwordEncoder());
    }
