WechatBakTool

WeChat chat record backup analysis tool developed based on C#, striving to be the most useful WeChat backup tool.

• Theoretically, it supports the 64-bit version of all WeChat and supports two methods of indirect address acquisition of Key[1]
• Workspace concept supports multiple WeChat switching operations.
• Supports exporting Html files, TXT files, and batch exporting
• Supports chat frequency analysis and full message library content search
• Currently the following types of message parsing are supported:
• text message
• picture
• voice
• share link
• group chat
• System messages
• document
• Quote/forward message
• Expressions (requires pre-download)

If you have any good suggestions or comments, or encounter any problems, you are welcome to raise an issue and I will reply when I see it.

Recent development plans

The technology stack of this project is: C# + .NET6.0 + WPF

• New version UI interface development
• Improve various message support (preliminarily completed)
• word cloud
• Performance optimization
• Pack resource folder
• Manual mode (suitable for offline analysis)
• Annual report analysis (waiting for art resources, will not be done if there are no resources)

Part of the problem

Q: Does it support mobile phone version?
A: Just use the migration function on the mobile phone . Path: Me->Settings->Chat->Chat record migration and backup->Migration

Q: How to export all records
A: Workspace->right-click->Manage, and you’ll see it.

Q: What should I do if the decryption workspace prompts no such teble:MSG?
A: Basically it is caused by the cache not being written to the database just after the migration. It is recommended to restart WeChat after the migration and then create a workspace.

Q: What should I do if the decryption workspace prompts no such teble:XXXXXXX
A: This reason is basically caused by decryption failure. It falls back to using the fixed address search method for decryption. Please ensure that your WeChat version is supported in version.json

Q: What should I do if I get the message Unable to load DLL 'libcrypto-1_1' or one of its dependencies when decrypting?
A: This is because the running environment of the encryption and decryption library is not satisfactory. Install the vc++2015 x64 runtime library and try again.

Instructions for use

0. Install .NET Desktop Runtime (note that it is version 6.0 of Desktop Runtime, ignore it if it is already installed)
1. Open WeChat and log in.
2. Click New Workspace at the bottom left side of the software.
3. In the new workspace interface , select the WeChat process to create the workspace, and confirm whether the WeChat ID below is correct
4. The decryption method is recommended to select user name inference search ! This method theoretically supports all 64-bit versions of WeChat. But this mode requires ensuring that the WeChat account is correct
5. Newbies please ignore other options and click Create Workspace directly. The program will automatically create and decrypt the workspace.

After the workspace is created, click on the workspace on the left to use it!

Reference/Citation

During the development process of the project, the following projects or materials were referenced, and relevant codes were quoted. If necessary, it is recommended that you refer to the following relevant materials:

1. C# uses OpenSSL to decrypt the WeChat database. Here, pay attention to the 64-bit adaptation issue and the dll reference. In addition, the decryption resource optimization is not very good. You can refer to what I rewritten. C# also needs to pay attention to the problem of oversized files: Mr0x01/WXDBDecrypt. NET
   
2. C# uses the address to obtain the WeChat Key: AdminTest0/SharpWxDump
3. To decrypt WeChat voice, I directly call decryption. Anyway, I need ffmpeg. One more is a lot, two more is a lot. I am too lazy to implement it: kn007/silk-v3-decoder
4. Decrypt WeChat pictures I love to crack chenhahacjl/WeChat DAT picture decryption (C#)
5. Refer to the handle name implementation, please don’t look here to obtain the handle, #10 This issue is blood and tears huiyadanli/RevokeMsgPatcher
6. Refer to the handle to obtain FuzzySecurity/Sharp-Suite
7. This method of obtaining the secret key is more general, SnowMeteors/GetWeChatKey, the user name is not very stable.

Other statements

[1] Theoretically supporting all 64-bit versions refers to user name inference and public key header inference. The direct address acquisition method requires version.json support, and updates are not very timely.
