Microsoft DOS fciv command
The fciv command is an external command that is not pre-installed with any version of Windows, it must be downloaded from Microsoft. Once installed it is executed using the fciv.exe external file. See the link below for full steps on installing and using the FCIV command.

Running the fciv against any file (in this case hope.txt) displays the file checksum information similar to the example below.
// File Checksum Integrity Verifier version 2.05.
fciv hope.txt -both
Running the above command gives the output for both MD5 and SHA-1.
fciv -add hope.txt -xml hope.xml
Add the MD5 information of the "hope.txt" file to the XML hope.xml file. If the file does not exist a new file will be created. Below is an example of the XML file created using this command.
<?xml version="1.0" encoding="utf-8"?>
