MD5 is like a "digital fingerprint" of a file. The MD5 value of any file is unique. If anyone makes any changes to this file, its MD5 value will change. Therefore, we can verify whether the file has been tampered with maliciously by comparing the MD5 value of the file. The PC download website compiles the best md5 verification tool for everyone. As long as you drag the downloaded software or tool into the software for calculation, you can get the MD5 value of the software, and then compare it with the MD5 value given by the official. It is very convenient to know whether the software you downloaded has been modified.
