If the file is manipulated some way then the hash will change. The purpose of publishing the hash is to help you verify that the file you are downloading is the actual file the developer is distributing. Please see this SHA256 hash example for our GlassWire installer version 2.2.201.

Software developers sometimes list the hash of a file when distributing it over the Internet to help others verify the file’s integrity.
What is one to do about the “REMark – initialization” are those commands?, are they “set” in some other folder? what? Anyway, thanks for trying.Why would someone want to know the hash of a file on Windows? Unix/Linx is better but overall the tech sphere does a good job repelling anyone who wants to learn a bit at a time rather than becoming a programmer.
MS Help is as useful as an ice-cube in hell. I do not know that about your instructions, only that they don’t work for me. In addition many of the “suggestions” for what to enter into a terminal are not proofread and usually don’t work because of a typo -some I’ve found most I’ve wasted time with.

I have used Unix terminal some and tried to use MSwhatthe f–k but always hit the same wall: the instructions assume the user already knows how to do whatever and just needs a little clarification i.e.: teckie talk to teckie. That is, you talk amongst yourselves NOT to us “uninitiated”. But I’m afraid you have made the same assumptions and/or mistakes as EVERY other teckie-trying-to-help-non-teckies that I’ve encountered over the years. Januat 10:59 C Berlin Thank you for your effort to help (at 2:31am!).

The remarks at the top show how to use the script, and there is also a usage prompt if no parameter is provided or the first parameter is a file that doesn’t off Here’s a script I wrote that takes the information in this article and shows or checks the checksum.

In the subsequent versions of Windows the case doesn’t matter. Be sure to type, for example, not “md5” but “MD5”. Hash Algorithms: Note that on Windows 7, the hash algorithms are case-sensitive.
