使用Spring Security 3哈希和腌制密码

Question

如何使用Spring Security 3散列密码并加密它们？

Answer 1

程序化的,你可以这样做:

在您的application-context.xml(在web.xml下contextConfigLocation定义)文件中定义bean(此示例使用md5).

<bean class="org.springframework.security.authentication.encoding.Md5PasswordEncoder" id="passwordEncoder" />

然后自动设置密码编码器:

@Autowired
PasswordEncoder passwordEncoder;

在您的方法中或您想要哈希和盐的任何地方.

passwordEncoder.encodePassword("MyPasswordAsString", "mySaltAsStringOrObject");

上面的调用应该返回一个salted哈希(作为a String).

应该这样做.我假设你可以找出你需要的罐子.

UPDATE

不言而喻,使用MD5并不是最好的主意.理想情况下,您应该至少使用SHA-256.这可以通过以下方式完成ShaPasswordEncoder.

将上面的MD5 bean配置替换为:

<bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.ShaPasswordEncoder">
     <constructor-arg value="256"/>
</bean>

Answer 2

最简单的似乎是Spring Security 3.1假设没有对散列方式的约束:

<bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>

<security:authentication-manager>
    <security:authentication-provider>
        <security:password-encoder ref="encoder"/>
        <security:jdbc-user-service data-source-ref="dataSource" users-by-username-query="select username,password, enabled from users where username=?" authorities-by-username-query="select u.username, ur.authority from users u, user_roles ur where u.username = ur.username and u.username =?"/>
    </security:authentication-provider>
</security:authentication-manager>


@Controller
@Stateless
public class UsersEJB {
    @PersistenceContext(unitName = "somePU")
    private EntityManager em;
    @Transactional
    public void create(Users users) {
        PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        String hashedPassword = passwordEncoder.encode(users.getPassword());
        users.setPassword(hashedPassword);
        em.persist(users);
    }
}

Answer 3

最简单的方法,如记录:

<authentication-manager alias="authenticationManager">
    <authentication-provider user-service-ref="userDetailsService" >
        <password-encoder hash="sha">
            <salt-source user-property="username"/>
        </password-encoder>
    </authentication-provider>
</authentication-manager>
