Java批量解析微信dat文件,微信图片破解

  • 前言
  • 关于异或值怎么计算
  • 代码
  • 第二种方式，适合不懂怎么计算，想直接用的代码

前言

偶然看到有可以解密微信dat的文档，上网查了查，找到了一篇可以用的文章，不过转换过程代码是有问题的，在这里改了下发布上来。
附带依赖jdk8的微信图片破解小工具：链接：https://pan.baidu.com/s/1t_e5rMFKmIRDNQAfN5rtaQ

关于异或值怎么计算

首先使用十六进制器打开微信dat文件，显示如下

jpg图片文件头一般为FF D8 开头的，所以此处使用科学计算器，计算异或值


计算后的值

所以此处异或值就是0x9D

代码

以下是java代码，创建一个weChatImgRevert .class后复制进去就好啦。
此处的jdk版本需要1.8以上…，另外三个参数需要改成自己的哦~

package main.java.com.example.demo;

import java.io.*;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.atomic.AtomicReference;

执行main方法后就可以在目标文件夹中去看转换后的图片了
以下是转换后的效果图片:

第二种方式，适合不懂怎么计算，想直接用的代码

以下是java代码，创建一个WxChatImgRevert.class后复制进去就好啦。
此处的jdk版本需要1.8以上…，另外两个参数需要改成自己的哦~
此处的原理是判断图片文件的十六进制特征码。
