file check

Sometimes we need to check the MD5 value of the file for some reason. Under Linux, this is very simple, just use the md5sum command, but we don't know the corresponding command on Windows. I checked some online today, and sure enough, Windows also has corresponding commands. And this command can also view the function of SHA1 value and SHA256 value. The command is as follows:

[plain]  view plain copy  

1. certutil -hashfile filename MD5  
2. certutil -hashfile filename SHA1  
3. certutil -hashfile filename SHA256
