★What is the purpose of the SHA256 digital signature

Issue: 

When downloading the software, there is a SHA256 digital signature. What is the content, and what is its function?

Solution:

A SHA256 refers to the hash value of the installer file. It is a unique value derived from the file using a specific algorithm.

By comparing the hash value of the downloaded file with that of the source file, we can verify its integrity. If the values match, it means the two files are identical, and the download process was not corrupted.

If they do not match, it indicates that the downloaded file differs from the original and may have been damaged during download.

 Here's how to use it:

1. Press the Win+ R keys on the computer, enter CMD.
   
   
2. Enter the following command.
   certutil.exe -hashfile <full path to the file that we want to get its sha256sum> sha256
   For example, if the file is target.tar, and its full path is d:\target.tar, then type: certutil.exe -hashfile d:\target.tar sha256
   The output will be like:
   SHA256 hash of target.tar:
