RustDesk Custom ID Tool

Introduction

Note that if a certain ID is invalid and reset, please try more IDs. For example, on my Mac computer, IDs starting with 'mac' are all reset to other random ID.

中文文档: README_CN.md

This project aims to provide a custom ID generation function for RustDesk, making it easier for users to remember and manage devices. The primary function is to simulate the official encryption algorithm, encrypting user-entered custom IDs and outputting the encrypted ID. By replacing the enc_id field in the configuration file with this output, users can complete the setup.

For MacOS, the configuration file is located at:

• ~/Library/Preferences/com.carriez.RustDesk/RustDesk.toml

For Windows, the configuration file is located at:

• C:\Users\username\AppData\Roaming\RustDesk\config\RustDesk.toml

When running in service mode in Windows, specified by --service :

• C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\RustDesk\config\RustDesk.toml

Features

• Generate encrypted custom ID
• Decrypt and validate encrypted ID
• Use UUID as the encryption and decryption key

Usage

Get UUID

1. Windows:

   • Press Win + R to open the Run dialog box.
   • Type regedit and press Enter to open the Registry Editor.
   • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography.
   • Copy the MachineGuid value as the uuid parameter.

2. MacOS:

   • Open Terminal.
   • Enter the following command: ioreg -rd1 -c IOPlatformExpertDevice | grep IOPlatformUUID
   • Copy the UUID from the output as the uuid parameter.

Validate UUID

1. Clone the code locally.
2. Find the enc_id field in the respective configuration file.
3. Run the command cargo run -- --eid $enc_id --uuid $uuid.
4. The program will output the decrypted ID, compare it with the current ID to check consistency.

Customize ID

1. Clone the code locally.
2. Run the command cargo run -- --eid $custom_id --uuid $uuid.
3. The program will output the encrypted ID, copy and replace it in the enc_id field of the configuration file.

Example of program execution:

cargo run -- --id 123456 --uuid 12345678-1234-1234-1234-123456789012

Encryption Process

This program uses the crypto::secretbox module in the sodiumoxide library for symmetric encryption. The encryption key comes from the provided UUID string.

1. Convert the custom ID string into a byte array.
2. Convert the UUID string into a byte array and adjust its size to match the key length requirement.
3. Use the sodiumoxide::crypto::secretbox module to create a key and nonce.
4. Choose encryption or decryption operation based on the encrypt parameter.
5. Use the secretbox::seal or secretbox::open function for encryption or decryption.
6. Convert the encrypted byte array to a base64 encoded string and output it to the console.
