Hash/Check is a simple app to verify downloaded files by hash.
That's it. That's the app.
The concept is very simple. You download a file. The website you downloaded a file from (nicely) provides
you with a hash to verify the file you have in your Downloads folder matches what the website thinks you downloaded.
The app was inspired by this post about a malicious copy
of HandBrake going around. As most people don't download a file, pop open the
Terminal and run
shasum /path/to/file and check the hashes match, I figured I'd make a go at
making the act of hash checking (see what I did there?) simple.
To that end, I created a quick app a few years ago and threw it in the App Store. It throws an icon on your Mac
status bar and when you download a file from a website, it will create the hash values of the most recent file in
Downloads folder - then all you have to do is select the hash on the website,
⌘ c is your friend, and
boom. It is either a match or it isn't.
