Description
Currently we link to the Github page of OpenHashTab, which of course is an .exe which must be downloaded and installed. The certutil command is already built into Windows:
https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/certutil
Example output:
C:\Users\user\Downloads>certutil -hashfile pfSense-plus-memstick-serial-22.05-RELEASE-amd64.img.gz sha256
SHA256 hash of pfSense-plus-memstick-serial-22.05-RELEASE-amd64.img.gz:
f14558ad85a8a38aea04c0e5989ea0099119fbaa94872fd54e8d69fbec7b2587
CertUtil: -hashfile command completed successfully
- % Done changed from 0 to 80
It'd be nice to have the PowerShell way listed as well, now that this shell is becoming essential in managing Windows based systems, plus others.
Get-FileHash -Algorithm SHA256 [-Path] {path to image}
https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-filehash
PS /home/user> Get-FileHash -Algorithm SHA256 -Path /home/user/Downloads/pfSense-CE-2.6.0-RELEASE-amd64.iso.gz
Algorithm Hash Path

PowerShell is definitely the way to go for this. Any supported version of Windows is going to have that available. No reason to prefer cmd prompt methods these days.
