+# WechatBakTool
+基于C#开发的微信聊天记录备份分析工具，努力做最好用的微信备份工具。

-本项目仅做学习使用，主要供个人备份自己的微信记录，请勿用于非法用途。
-本项目严禁商用。
-如果有什么好的建议或意见，或者遇到什么问题，欢迎提issue，看到会回。
+- 理论支持64位版本所有微信，支持两种方式非直接地址获取Key[1]
+- 工作区概念，支持多微信切换操作。
+- 支持导出Html文件，TXT文件，支持批量导出
+- 支持聊天频率分析，全消息库内容搜索
+- 目前支持以下类型消息解析
+- [x] 文本消息
+- [x] 图片
+- [x] 语音
+- [x] 分享链接
+- [x] 群聊
+- [x] 系统消息
+- [x] 文件
+- [x] 引用/转发消息
+- [x] 表情(需要预下载)

-#### 使用
-<p>1.打开微信，并登录。</p>
-<p>2.在工作区上方点击新增，选择要创建的工作区微信</p>
-<p>3.点新建会弹出Handle64的协议说明，同意即可。如没有内容显示，重新点一下新建即可</p>
-<p>4.选中刚刚创建的工作区，点击解密。（如当前多开微信，请选择对应的微信进行解谜）</p>
-<p>5.选中刚刚创建的工作区，点击读取</p>
-<p><b>尽情使用吧！</b></p>

-#### 注意
-<p>本项目基于.NET开发，需要安装.NET Desktop Runtime，如未安装，双击EXE时会提示。</p>
-<p>如果使用过程中发生崩溃，请删除工作区试一下，工作区即根据用户名在运行目录下生成的md5文件夹。</p>
-<p>已解密的工作区可以直接读取。</p>

+**本项目完全免费，问你要钱的都是骗子**<br/>
+**使用本项目初衷是作者研究微信数据库的运行使用，您使用本软件导致的后果，包含但不限于数据损坏，记录丢失等问题，作者不承担相关责任。**<br/>
+**因软件特殊性质，请在使用时获得微信账号所有人授权，你当确保不侵犯他人个人隐私权，后果自行承担**<br/>
+<br/>
+
+### 隐私声明
+**本项目不会上传任何你的数据至任何第三方系统**<br/>
+**如果发生任何回传行为，请检查是否为第三方修改版本**<br/>
+<br/>
+
+### 近期开发规划
+本项目技术栈为：
+C# + .NET6.0 + WPF <br/>
+- [x] ~~新版本UI界面开发~~
+- [x] 完善各类消息支持（已经初步完成）
+- [x] ~~词云~~
+- [ ] 性能优化
+- [ ] 打包资源文件夹
+- [ ] 手动模式(合适离线分析)
+- [ ] 年度报告类分析(等美术资源中，没有资源不做)

+
+### 部分问题
+Q：支持手机端吗<br/>
+A：<b>在手机端</b>使用迁移功能即可，路径：我->设置->聊天->聊天记录迁移与备份->迁移<br/>
+<br/>
+Q：怎么导出全部的记录<br/>
+A：工作区->右键->管理，就见了。<br/>
+<br/>
+Q：解密工作区提示no such teble:MSG怎么办<br/>
+A：基本上都是因为刚迁移完，缓存没写入到数据库导致的，建议迁移完重启一次微信后再创建工作区<br/>
+<br/>
+
+### 使用说明
+0.安装.NET Desktop Runtime(注意是6.0版本的Desktop Runtime，如已经安装忽略)<br/>
+1.打开微信，并登录。<br/>
+2.在软件左侧下方点击**新建工作区**，<br/>
+3.在**新建工作区界面**，选择要创建工作区的微信进程，并**确认下方微信号是否正确**<br/>
+4.解密方式**推荐选择用户名推断查找**！该方式理论支持所有64位版本微信。**但该模式需要确保微信账号正确**<br/>
+5.新手请忽略其他选项，直接**点击创建工作区**，程序会自动进行工作区创建、解密。<br/><br/>
+**工作区创建完毕，点击左侧工作区，尽情使用吧！**<br/>
+<br/>
+
+### 参考/引用
+项目在开发过程中参考了以下项目或资料，有引用相关代码，如有需要，推荐您可以去参考下相关资料：
+
+1. C#使用OpenSSL解密微信数据库，这里注意一下64位适配问题，注意dll引用，另外解密的资源优化不是很好，可以参考一下我改写的，C#还需要注意一下超大文件的问题： [Mr0x01/WXDBDecrypt.NET](https://github.com/Mr0x01/WXDBDecrypt.NET)<br/>
+2. C#使用地址获取微信Key： [AdminTest0/SharpWxDump](https://github.com/AdminTest0/SharpWxDump)
+3. 解密微信语音，我是直接调用解密，反正都要ffmpeg，多一个也是多，多两个也是多，懒得头铁实现： [kn007/silk-v3-decoder](https://github.com/kn007/silk-v3-decoder)
+4. 解密微信图片 [吾爱破解chenhahacjl/微信 DAT 图片解密 （C#）](https://www.52pojie.cn/forum.php?mod=viewthread&tid=1507922)
+5. 参考了句柄名称实现，注意获取句柄别看这里，#10 这个issue就是血泪 [huiyadanli/RevokeMsgPatcher](https://github.com/huiyadanli/RevokeMsgPatcher)
+6. 参考了句柄获取 [FuzzySecurity/Sharp-Suite](https://github.com/FuzzySecurity/Sharp-Suite)
+7. 这个获取秘钥更通用一些 [SnowMeteors/GetWeChatKey](https://github.com/SnowMeteors/GetWeChatKey) ,用户名不是很稳定
+
+### 其他声明
+[1] 理论支持所有64位版本指用户名推断和公钥头推断，地址直接获取方式需要version.json支持，更新不是很及时。
