Wouldn’t it be nice to right click on a file and calculate the MD5 or SHA-1 checksum? That’s what I wanted to do and this is how I did it!

Download the [Microsoft File Checksum Integrity Verifier (FCIV)][1] and extract to where ever. It will have a file called fciv.exe that you should copy to C:\Windows\System32\ (You can alternatively add an additional path parameter to the system environmental variables that points to the directory that contains fciv.exe)

Then open regedit and add the appropriate keys:


Now right click any file and there will be a “Checksum” option that you can select and it will automatically calculate the MD5 and SHA-1 checksum :smile:
