spring security使用哈希加密的密码

以前咱们都是使用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,如今推荐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。
首先咱们使用spring提供的加密方法对密码 123456 进行加密:
一、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
二、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
这里须要注意,保证数据库密码字段的长度为60或者大于60,不然字符串会被截断。
 
1、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
这里须要自定义。
一、创建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");
    }
}
二、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便可。
一样适用于SHA加密。
2、使用BCrypt加密算法:
一、只须要在 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:若是使用的是 jdbcAuthentication,安装以下配置便可
@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 = ?");
    }
启动测试便可
