simple checksum

checksum's little brother!

Wherever checksum goes, his wee brother usually tags along. He's called simple checksum, an ultra-low profile desktop application, designed for ad-hoc drag-and-drop hashing tasks. He's the good-looks to checksum's muscle, which he borrows. He really is a mere strip of a lad!..

Simple..

Yes, but he's smarter than he looks, and not only supports drag-and-drop file hashing, but on-demand string hashing, as well as hash-perfect file comparison. You can also drag and drop files directly onto his program icon (or a shortcut to it, maybe on your desktop), as well as supply file names on the command-line, to launch immediately into a checksum calculation or comparison job. Simple, sure, but clever, too!

Fast..

Uses the same ultra-fast hashing engine as his big brother, checksum. Enough said.

Yet, fully featured..

Supports both MD5 and SHA1 hashing algorithms, completely FREE (it comes with checksum). So feel free to throw a shortcut somewhere handy (maybe in your SendTo menu), always ready for instant hashes and file comparison jobs.
simple checksum is designed to sit out-of-the-way somewhere, and supports transparency and "always on top" bit-setting for extended desktop usage, enabling you to do visual comparisons of online checksums, even with your web browser open full screen.

You can show/hide simple checksum by simply clicking its system tray icon. Everything has ToolTip help, even the system tray icon.

Easily switch between MD5 and SHA1 hashing with HotKeys or via simple checksum's application menu - simple checksum will recalculate the hash using the new algorithm, without the need for a second drag-and-drop.



Launch simple checksum with a file (via drag & drop, SendTo, etc.), and get an instant MD5 or SHA1 hash, ready to view or copy into your clipboard.

simple checksum's new Auto.. menu enables you to automatically send your hashes to either your Windows® ClipBoard, or directly to a fresh .hash file, as part of one simple drag and drop. Switch algorithm (Alt-M or Alt-S) and with AutoSave enabled, you've got yourself a MD5+SHA1 MultiHash™ from a single drag and drop!

Drop Two files, and simple checksum transforms into a simple, highly efficient file comparison utilty…

File Compare..

Drop Two files onto simple checksum; either the program itself (or a shortcut to it), or directly onto its input, and simple checksum will compare them, using your currently selected hashing algorithm. If the files are identical, you get "Files MATCH!", and if not, "Files DO NOT MATCH!", simple as that.

If required, you can get to the actual hashes by hitting Alt-C. If the hashes were different, hitting Alt-C a second time will get you the second hash. From then on, Alt-C toggles between the two hashes.

When comparing files, if AutoCopy is enabled, your clipboard will contain a mini-report, with the two file names, their individual hashes, and right at the top, the status of the file comparison; match or not.

Web Hash Compare..

If you drop a file onto simple checksum's input and there is already a hash in your clipboard, simple checksum will compare the hash of the dropped file with that in the clipboard and report whether or not they match (rather than report the hash string - if you need that, IT'S IN YOUR CLIPBOARD!)

This makes it a no-brainer to compare the hashes of download files with the hashes published on web sites, simply copy the hash from the page (select it, hit Ctrl+C) and then drop the downloaded file into simple checksum. TADA! If you have the latest beta, this will also work on launch.

It also means that you can compare the hashes of two files that are not physically next to each other; with Auto-Copy enabled, drag the first file into simple checksum - its hash is placed in the clipboard. When you drag-and-drop the second file, simple checksum will compare its hash to the one in the clipboard.

NOTE: simple checksum will automatically switch between MD5 and SHA1 hashing depending on the type of hash in your system clipboard.

NOTE: If you have Auto-copy-to-clipboard enabled, it will deactivate when comaring hashes with the clipboard, your original hash will still be there after the operation.

It's FREE!

simple checksum is FREE! (it is intalled along with checksum)

After a month or so, checksum will occasionally remind you that it is Shirtware, but simple checksum keeps on working without interruption, for life. En-joy!
