(Sometimes colons or spaces are used to group the checksum.) Make sure to compare it to the checksum with the right algorithm (SHA-256). It has to match for all hexadecimal digits. Once you have entered the command, it will return an alphanumeric string, which you can compare to the one on the Gpg4Win package integrity site. Open a command line, navigate to your Download-Folder, and use a command like the following, but adapt the filename to the version you have downloaded and you want to check:Ĭertutil -hashfile gpg4win-3.1.15.exe sha256 Once you have downloaded the file, you can verify that it matches the published checksums (that you have gotten via a trusted channel).
