Use image storage account password

Use the image to keep the account password-Linux general technology-Linux technology and application information. The following is a detailed description. You can use images to save account passwords or other text data.

You can use gimp to create an image. As an example, download an image over the Internet and save it as 1.jpg. Then a new license file is created, and the name is 2.txt. Enter a small amount of content, such as "123456 press ENTER www.linux110.com press enter admin press Enter password"
Then run the command
Cat 1.jpg 2.txt> 3.jpg
A new image file 3.jpg is displayed, but the text data is hidden.
Use the image watermark tool to open the image. The content is the same as that of 1.jpg.
To view the content, run more, less, vim, cat, and other commands. Skip the garbled part of the image and jump to the end to view the saved text.

This method saves things you don't want to see. It is not very safe, but it should be enough for people who just double-click with the mouse.
