Calculating the MD5 checksum of a file under Windows

I was working on my Windows laptop and needed to calculate the MD5 checksum of a file. Under Linux no problem, but how do you do that under Windows? As always Google is your friend. I found the Microsoft File Checksum Integrity Verifier tool on the Microsoft website. Easy to install and use.

These are the steps

  • Download the tool from here
  • Unpack it to a directory of your choice

To calculate the MD5 checksum of a file run the following command:

fciv <filename>

To calculate the SHA1 checksum of a file run the following command:

fciv -sha1 <filename>

To calculate both the MD5 and the SHA1 checksum of a file run the following command:

fciv -both <filename>

Easy, right?
