This Go code encrypts files in a specified directory, generates a wallpaper image, and sets it as the desktop wallpaper. Additionally, it logs the details of encrypted files.

• Go programming language installed
• Basic understanding of Go programming concepts
• Windows operating system

1. Modify the root variable in the code to specify the root directory where encryption should start. For Windows systems, the default is C:\.

2. Update the key variable to set the encryption key. The key should be a 16-byte byte array.

3. Run the program using the command go run main.go in the terminal.

4. The program will encrypt files with extensions .docx, .xlsx, and .pptx in the specified directory and its subdirectories.

5. The encrypted files will be saved with a .goblok extension in the same location as the original files.

6. The program will generate a new wallpaper image with the text "silahkan periksa file anda" and save it as output.png in the temporary folder.

7. The generated wallpaper image will be set as the desktop wallpaper.

8. The program will create a log file named encryption.log in the same directory. The log file will contain details of each encrypted file in the format filename with extension | encrypted filename with extension | directory.

9. After execution, check the log file for the encrypted file details.

• To encrypt files with different extensions, modify the ext comparison in the code to include the desired file extensions.

• To change the text on the wallpaper image, modify the addLabel function in the code.

• To set the wallpaper image from a different location, update the tempFile variable with the desired file path.

• The code provided is for educational purposes and should be used responsibly.

• Encrypting files indiscriminately can have serious consequences. Ensure you have appropriate permissions and take necessary precautions before running the code.

• Changing the desktop wallpaper requires administrative privileges.

• Always back up important files before encryption.
