Your files have secrets. Hash/Check knows how to ask nicely. Drop a file, verify a hash, sleep soundly. Now watching your Downloads folder so you don't have to.
Hash/Check is the no-nonsense (okay, maybe a little nonsense) hash calculator for macOS.
Drop a file — any file — and Hash/Check instantly serves up its MD5, SHA1, SHA256, SHA384, and SHA512 fingerprints. Copy a hash from the internet, and Hash/Check quietly checks whether your download is the real deal. Green means go. Red means… maybe don't open that.
Works the way you work:
- Drag & drop files onto the window, or use the menu bar extra for quick checks without leaving your flow
- Clipboard magic — copy a hash from anywhere and Hash/Check matches it automatically
- Finder Quick Actions — right-click any file to hash it on the spot via Shortcuts
- Downloads watcher — turn on "Monitor Downloads folder" and Hash/Check keeps an eye on new arrivals. When the app is open, it asks if you'd like to hash them. When you're running lean in the menu bar, it just goes ahead and does it
- Dark mode, light mode, auto mode — Hash/Check follows your lead
No subscriptions. No telemetry. No funny business. Just hashes.

It worked

I've never used a tool like this before. Very easy. I downloaded qBittorrent and before opening the installer I dragged the image to Hash/Check and the app automatically copied the checksum from my clipboard and highlighted if there was a match or not. (make sure to highlight and copy (ctrl-c) the checksum you want to check against before dragging the downloaded image your checking into this app.
Simple, easy hash checking

Finally an easy way to check hashes without wasting a few minutes running commands and shell scripts. THANK YOU!
Compare function not intuitive and broken
MC Ringbearer
Having to copy a hash value into the clipboard BEFORE calculating the hash is counter intuitive. You should simply allow user to PASTE a value into the compare field at the bottom. I wasted five minutes trying to figure out. Then as a test, I pasted garbage value into the clipboard then calculated the hash, and the app said Clipboard Match! across ALL algorithms, which is obviously incorrect. Completely unreliable.
Possible Malware

Program refuses to quit and cannot be accessed from MacOS Force Quit. Performs operations using the CPU even when not attempting to hash a file. Beware!
Developer Response
** Update: yes, it has been a while, a whole year! So the issue was if you have a Very Large File™ in your downloads folder (such as having just downloaded Xcode) the app would try to create hashes of said Very Large File™ and would beachball due to ... well, not having implemented the app using modern async/multithreading techniques. Well, you're in luck as Version 2.0 has fixed the Beachball of Doom. Yay!
Hash/Check got some upgrades. Nothing too flashy — just the good kind.
GitHub copies weird. Hash/Check is ready.
- Copying a hash from a GitHub release page tacks on a prefix like `sha256:` before the actual hash. Hash/Check now quietly strips that off and matches correctly. No manual editing required.
Monitor Downloads folder
- Turn it on in Settings and Hash/Check keeps watch over your Downloads folder. Pop open the app window and a friendly banner will ask if you want to hash whatever just landed. Running in the menu bar? It'll just hash it automatically and have the answer waiting for you.
A few things that were mildly annoying are now not annoying:
- The app no longer shows a "Calculate Hashes" button on a blank screen when nothing is loaded
- The menu bar popover now respects the "Monitor Downloads folder" setting instead of cheerfully loading your latest download whether you wanted it to or not
