spring security使用哈希加密的密码

之前我们都是使用MD5 Md5PasswordEncoder 或者SHA ShaPasswordEncoder 的哈希算法进行密码加密,在spring security中依然使用只要指定使用自定义加密算法就行,现在推荐spring使用的BCrypt BCryptPasswordEncoder,一种基于随机生成salt的根据强大的哈希加密算法。
首先我们使用spring提供的加密方法对密码 123456 进行加密:
1、使用MD5加密:
package com.petter.util;import org.springframework.security.authentication.encoding.Md5PasswordEncoder;/** * @author hongxf * @since 2017-04-11 10:52 */public class MD5EncoderGenerator {    public static void main(String[] args) {        Md5PasswordEncoder encoder = new Md5PasswordEncoder();        System.out.println(encoder.encodePassword("123456", "hongxf"));    }}
修改数据库中的用户hxf密码为 7cbdf569746dd62484eb25a55b7df2dc
2、使用BCrypt加密:
package com.petter.util;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;/** * @author hongxf * @since 2017-04-10 10:01 */public class PasswordEncoderGenerator {    public static void main(String[] args) {        String password = "123456";        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();        String hashedPassword = passwordEncoder.encode(password);        System.out.println(hashedPassword);    }}
修改数据库中的用户hxf密码为 $2a$10$f0DEGrkIpYyzcFrf/fTMSOAKl1Y/XHpKaijWdfiWnOOzGTEs8diLi
这里需要注意,保证数据库密码字段的长度为60或者大于60,否则字符串会被截断。
 
一、使用MD5加密算法:
spring security已经废弃了org.springframework.security.authentication.encoding.PasswordEncoder接口,推荐使用org.springframework.security.crypto.password.PasswordEncoder接口
这里需要自定义。
1、建立自定义密码加密实现类CustomPasswordEncoder
package com.petter.config;import org.springframework.security.authentication.encoding.Md5PasswordEncoder;import org.springframework.security.crypto.password.PasswordEncoder;/** * @author hongxf * @since 2017-04-11 10:39 */public class CustomPasswordEncoder implements PasswordEncoder {    @Override    public String encode(CharSequence rawPassword) {        Md5PasswordEncoder encoder = new Md5PasswordEncoder();        return encoder.encodePassword(rawPassword.toString(), "hongxf");    }    @Override    public boolean matches(CharSequence rawPassword, String encodedPassword) {        Md5PasswordEncoder encoder = new Md5PasswordEncoder();        return encoder.isPasswordValid(encodedPassword, rawPassword.toString(), "hongxf");    }}
2、在SecurityConfig中进行配置
@Bean    public PasswordEncoder passwordEncoder(){        return new CustomPasswordEncoder();        //return new BCryptPasswordEncoder();    }    @Override    protected void configure(AuthenticationManagerBuilder auth) throws Exception {        authenticationProvider.setPasswordEncoder(passwordEncoder());        auth.authenticationProvider(authenticationProvider);    }
直接把自定义的类设置即可。
同样适用于SHA加密。
二、使用BCrypt加密算法:
1、只需要在SecurityConfig中进行配置
@Bean    public PasswordEncoder passwordEncoder(){        //return new CustomPasswordEncoder();        return new BCryptPasswordEncoder();    }    @Override    protected void configure(AuthenticationManagerBuilder auth) throws Exception {        authenticationProvider.setPasswordEncoder(passwordEncoder());        auth.authenticationProvider(authenticationProvider);    }
 
PS:如果使用的是jdbcAuthentication,安装如下配置即可
@Bean    public PasswordEncoder passwordEncoder(){        return new BCryptPasswordEncoder();    }    @Override    protected void configure(AuthenticationManagerBuilder auth) throws Exception {        auth.jdbcAuthentication().dataSource(dataSource).passwordEncoder(passwordEncoder())                .usersByUsernameQuery("select username,password, enabled from users where username = ?")                .authoritiesByUsernameQuery("select username, role from user_roles where username = ?");    }
启动测试即可
