point-and-click MD5, SHA1 and BLAKE2 hashing for Windows..
The world's fastest hashing application, just got faster!
Welcome to checksum, a blisteringly fast, no-nonsense file hashing application for Windows, a program that generates and verifies BLAKE2, SHA1 and MD5 hashes; aka. "MD5 Sums", or "digital fingerprints"; of a file, a folder, or recursively, even through an entire disk or volume, does it extremely quickly, intelligently, and without fuss. Many people strongly believe it to be the best hashing utility on planet Earth.
Did I say fast? Not only mind-blowing hashing speeds (way faster than your hard drive!) but the quickest "get stuff done" time. With checksum you point and click and files, folders, even complete hard drives get hashed. Or verified. Simple. checksum just gets on with the job. Click-and-Go..
Available for 64 bit or 32 bit Windows (a basic Linux/UNIX/BSD version is also included).
In the decade before checksum, I must have installed and uninstalled dozens, perhaps hundreds of Windows MD5 hashing utilities, and overwhelmingly they leave me muttering "brain-dead POS!" under my breath, or words to that effect, or not under my breath. I always knew that data verification should be simple, even easy, but it invariably ended up a chore.
Either the brain-dead programs don't know how to recurse, or don't even pretend to, or they give the MD5 hash files daft, generic names, or they can't handle long file names, or foreign file names, or multiple files, or they run in MS DOS, or choke on UTF-8, or are painfully slow, or insist on presenting me with a complex interface, or don't have any decent hashing algorithms, or don't know how to synchronize new files with old, or have no shell integration or any combination of these things; and I would usually end up shouting "FFS! JUST DO IT!!!".
No more! Now I have checksum, and it suffers from none of these problems; as well as adding quite a few tricks of its own..
What is it for, exactly?
Peace of mind! BLAKE2, SHA1 and MD5 hashes are used to verify that a file or group of files has not changed. Simple as that. This is useful, even crucial, in all kinds of situations where data integrity is important.
For instance, these days, it's not uncommon to find MD5 hashes (and less rarely now, SHA1 hashes) published alongside downloads, even Windows downloads. This hash, when used, ensures that the file you downloaded is exactly the same file the author uploaded, and hasn't been tampered with in any way, Trojan added, etc.; even the slightest change in the data produces a wildly different hash.
It's also useful if you want to compare files and folders/directories; using checksums is far more accurate than simply comparing file sizes, dates or any other property. For quick file compare tasks, there's also checksum's little brother; simple checksum, simply drag & drop Two files for an instant hash-accurate comparison.
If you burn a lot of data to CD or DVD, you can use checksum to accurately verify the integrity of your data right after a burn, and at any time in the future. If you distribute data in any way, maybe torrenteering your favourite things, run a file server of some kind, or just email a few files to your friends; hashes enable the person at the other end to be absolutely sure that the file arrived perfectly, 100% intact.
As well as providing secure verification against tampering, virus infection, file (and backup file) corruption, transfer errors and more, digital fingerprints can serve as an "early warning" of possible media failures, be they optical or magnetic. It was a hash failure that recently alerted me to a failing batch of DVD-R disks; I saved my fading data in time, and got a refund on the disks. I'll leave you to consider the million other uses. There's only one reason, though; peace of mind.
Absolutely no-nonsense file verification..
checksum can create (two clicks, or a drag-and-drop) or verify (one click) hashes of a file, a folder, even a whole disk full of files and folders in one simple, no-nonsense, high-performance operation. Basically, you point it at a file or folder and go! The parameters are controlled by command-line switches, but most folk won't have to worry about that; it all happens invisibly, and is built-in to your Windows® Explorer context (aka "concept", aka "right-click") commands (see above).
Note: while checksum operates with command-line switches, it is NOT a Windows® console application; there's no messy DOS box, or anything like that. But if you want to run it from a console, that's covered, too.
There are a wealth of command-line options, but most people find that checksum just works exactly as they would expect, without any messing about; right-click and go! But, if you are the sort who likes to customize and hack at things, you will find plenty to keep you occupied!
If you want to change any of checksum's options on-the-fly, simply hold down the SHIFT key when you select its Explorer context menu item, and checksum will pop up a dialog for you to tweak the process. If you want to have anything permanently set, checksum comes with standard plain text Windows ini file for you to tweak to your heart's content. Anyone smart enough to use MD5sums, can edit plain text.
The options dialog is most useful when you want to only hash certain files in a folder, like mp3's, or movies. With your file mask groups, you can configure file-type specific hashing with just a couple of clicks.
You pop up the options by holding down the SHIFT key when you select the explorer menu item, so it's easy to get to the advanced options whenever you need them. Same goes for verification, though generally you won't need it - checksum is smart enough to just get on with the job, verifying whatever checksum files it finds in the path, be they MD5, SHA1 or BLAKE2, or all of the above, and you'll probably never need to use anything but the default verify command, no matter how advanced you are! And because checksum recognizes other formats of MD5 and SHA1 files (there is no standard BLAKE2 format), it can be used not only to verify and create new checksums, but also verify existing checksum files, even ancient ones, automatically.
I expect there is some weird MD5 file format out there that I don't have an example of, Wang, maybe? but in practice, checksum supports ALL known MD5 verification file formats, that is, known by me. If you find an MD5 file format that checksum doesn't support, !
There isn't really a standard SHA1 format yet, but checksum's is pretty good (it's the same as the output from a *NIX sha1sum command in binary mode). Shall we?
checksum usually operates as a regular installed desktop application with Explorer context menus, custom
.blake2 desktop icons, Windows start menu entries, and so on; but checksum can also operate in a completely portable state, and happily works from a pen-drive, DVD, or wherever you happen to be; no less than total portability.
Even with its little brother, simple checksum tagging along, the whole lot fits easily on the smallest pen-drive (the 32 bit version will UPX onto a floppy disk!), enabling you to create BLAKE2, SHA1 and MD5 hashes, wherever you are. To activate portable mode, simply drop a
checksum.ini file next to
checksum.exe (or run one-time with the "
portable" switch), you're done.
It's no problem to run checksum both ways simultaneously, or to run checksum in portable mode on a desktop where checksum is already installed. Simply put, if there's a
checksum.ini next to it, checksum will use it, and if there isn't an ini there, checksum uses the one in your user data folder (aka. "Application Data", aka. "AppData").
If you like applications to run in a portable state, even on your own desktop, no problem; you can skip the installer altogether and simply copy the files (
simple checksum.exe) to wherever you like. They are in the installer's
files/ directory inside the main zip archive. There's also a
checksum.ini inside the archive, so you can unzip-and-go.
Note: Regardless of whether you install checksum or run it in a portable state, its functionality is identical.
Introducing.. The Unified Hash Extension™
checksum uses the MD5, SHA1 and BLAKE2 hashing algorithms, and can create
.b2 or whatever you use) files to contain these hashes. But checksum prefers to instead create a single
.hash extension for all your hash files, whatever algorithm you use. Welcome to the unified
I feel there are quite enough file extensions to deal with, and with some effort on the part of software developers, this may catch on. I hope it does, anyway, and that you agree. A single, unified hash extension looks like the way forward, to me. All comments welcome, below.
As well as being able to verify MD5, SHA1 and BLAKE2 hashes, even mixed up in the same file, checksum can also create such a file, if you so desire. At any rate, if you start using BLAKE2 or SHA1 hashes some day, you can keep your old MD5 hashes handy, inside your
The single, unified hash extension gives us not only the freedom to effortlessly upgrade algorithms at any time, without having to handle yet-another-file-type, but also the ability to easily store output from multiple hashing algorithms inside a single
.hash file. Welcome to multi-hashing, which will doubtless have security benefits, to boot (a multi-hash is simply collision-proof).
If you do a lot of hashing, you will know that it's an intensive process, and relatively slow. Well, checksum is fast, lightning fast.
Even on my old desktop (a lowly 1.3GHz, where checksum was initially developed) it would rip through a 100MB file in under one second. The latest checksum can crunch data faster than any hard drive can supply it. Hashing your average album or TV episode is instantaneous.
With right-click convenience, intelligent recursion and synchronization, full automization, and crazy-fast hashing speeds, digital fingerprinting is no longer a chore, it's a joy!
Okay, I'm getting carried away, but seriously, this is how hashing was always meant to be.
If you like lists, and who doesn't, here's a list of checksum's "features", as compared to your average md5 utility..
True point-and-click hash creation and verification..
No-brainer hash creation and verification. In a word; simple.
Choice of MD5, SHA1 or BLAKE2 hashing algorithms..
Create a regular MD5sum (128-bit), or further increase security by using the SHA1 algorithm (160-bit). For the ultimate in security, you can create BLAKE2 hashes (technically, BLAKE2s-256, which kicks the SHA family's butt in both security AND hashing speed). checksum recognizes and works with all these formats, even mixed up in the same file.
hash single files, or folders/directories full of files.. no problem..
checksum can create hash files for individual files or folders full of files, and importantly, automatically recognizes both kinds during verification, verifying every kind of checksum file it can find. Also, when creating individual hash files, checksum is smart enough to skip any that already exist.
Effortless recursion (point at a folder/directory or volume and GO!) ..
Not only fully automatic creation and verification of files, and folders full of files, but hash all the files and folders inside, and all the folders inside them, and so on, and so on, through an entire volume, if you desire.. one click! ... Drive hashing is now officially EASY!
LONG PATH support..
All checksum's internal file operations use UNC-style long paths, so can easily create and verify hashes for files with paths of up to 32,767 characters in length. Goodbye
Full UNICODE file name support..
checksum can work with file names in ANY language, even the tricky ones like Russian, Arabic, Greek, Japanese, Belarusian and Urdu. checksum can also handle those special characters and symbols that lurk inside many fonts. In short, if you can use it as a Windows file or folder name, checksum can hash it!
"root", folder or individual file hashes, your call..
Some people prefer hashes of folders, some prefer "root" hashes (with an entire volume's hashes in a single file). Some people like individual hashes of every single file. I like all three, depending on the situation, and checksum has always been able to do it all.
checksum can mail you when it detects errors in your files; especially handy for scheduled tasks running while you are away or otherwise engaged. checksum's Mail-On-Fail can do CC, BCC, SSL, single and multiple file attachments (including attaching your generated log file), mail priority and more.
Multiple user-defined file mask groups..
For instance, hash only audio files, or only movies, whatever you like, available from a handy drop-down menu. All your favourite file types can be stored in custom groups for easy-peezy file-type-specific hashing. e.g..
The most common groups are already provided, and it's trivial to create your own. You can also enter custom masks directly into the one-shot options, e.g.
report*.pdf, to hash all the reports in a folder, create ad-hoc groups, or whatever.
Automatic music playlist creation..
Another killer feature; checksum can create music playlist files along with your checksums! When creating a folder hash, if checksum encounters any of the music files you have specified in your preferences; mp3's, ogg files, wma, whatever; it can create a playlist for the collection (i.e.. the album). Rather nifty, and a perfect addition to the custom command in the tips and tricks section.
As well as regular Windows standard
.m3u/m3u8 playlist files (Winamp, etc.), checksum also supports
.pls (shoutcast/icecast) playlists.
Effortlessly handles all known** legacy md5 files..
If you discover an MD5sum that checksum doesn't support,
Create lowercase or UPPERCASE checksums at will..
Like many things, this can also be set permanently, if you so wish.
Automatic synchronization of old and new files..
Automatically add new hashes to existing checksum files.
That's right! Automatically add new hashes to existing checksum files!
Integrated Windows® Explorer context (right-click) operation..
The installer will setup Windows® Explorer context commands for all files and folders, so you can right-click anything and create or verify checksums at will. Very handy. "setup", the rather clever installer, is also available in its own right, as a free, and 100% ini-driven installer engine for your own goodies. Stuffed with features, easy to use, and definitely deserving a page to itself. Soon.
As explained above, you can also bypass the installer altogether, and simply unzip-and-go, for 100% portable checksumming. Or you can have both.
One of checksum's special startup tasks is a Scheduler Wizard, which will guide you simply through the process of creating a checksum scheduled command in Windows Task Scheduler.
Click a few buttons, set your preferences in the familiar one-shot options dialog, and go!
No-fuss intelligent checksum verification..
Cut and paste your own checksum files if you like, rename them, mix and match legacy MD5 formats in a single file, even throw in a few SHA1 or BLAKE2 hashes just for fun; worry not; checksum will work it out!
Permanently ignore any file types..
Obviously we don't want checksums files of checksum files, for starters, but if you have other file types you'd like on a permanent ignore,
thumbs.db, whatever; it's easy to setup. The most common annoying file types already are.
As well as a set of permanently ignored folders (like "System Volume Information", $RECYCLER, and so on) you can set custom ignore masks on a per-job basis, using standard Windows file masks, e.g. "
foo*" or "
Real-time tool-tip style dynamic progress update..
Drag it around the screen - it snaps to the edges, and stays there (checksum also remembers its dialog screen positions, for intuitive, fast operation).
Tool-tip progress can be disabled altogether, if you wish.
Right-click the Tooltip for extra options.
During verification, any failures can be seen real-time in a system tray tool-tip, hover your mouse over the tray icon for details. checksum also flashes the progress tooltip red momentarily, and (optionally) beeps your PC speaker, to let you know of any hash failures. If there were errors, the final tooltip is red (by default). Anything to make life a bit easier.
Verify a mix of multiple (and nested) MD5, SHA1 and BLAKE2 checksum files with a single command..
Does what it says on the can!
Extensionless checksum files..
Traditionally, individual checksum files are named
filename.ext.md5. Personally, I find this inelegant, and prefer them to be named
filename.md5. I like it so much, I made it the default, but you can change that, if you like. When running extensionless; if checksum encounters multiple files with same name, it simply adds them to the same checksum file, so checksums for
foo.jpg would all go inside
foo.md5, or better yet,
foo.hash. Highly groovy.
On the verify side of things, checksum has always verified every possible checksum it can find, so these multi-hash file look just like regular folder hash files, and verify perfectly, so long as the data hasn't changed, of course!
Search & Verify Single Files..
With checksum, you can verify a single file, anywhere in your system, from anywhere in your system, regardless of where its associated
.hash file is in the file tree, be it in a folder or root (aggregate) hash.
checksum will search up the tree, first looking for matching individual
.hash files, and then folder hashes, all the way up to the root of the volume until it finds one containing a hash for your file, at which point it will verify that one hash and return the result. Another fantastic time-saver!
This works best as an explorer context menu command (supplied).
Smart checksum file naming, with dynamic @tokens..
checksum file names reflect the actual files or folders checked! Automatically.
If you want more, you can specify either static or dynamic checksum file names, with a wide range of automagically transforming tokens. See below for details.
Report Changed/Corrupt/Missing States..
checksum can optionally store a file's modification date and time along with the checksums, like so..
Thanks to the extra information, during verification checksum will report files with mismatched hashes as either "CHANGED" (they have been modified by some user/process) or "CORRUPT", where the modification time stamp is unchanged.
These will show as a different color in your HTML logs.
You can choose whether or not to report (and log) missing, changed, or corrupted files. For example, if you only want to know about CORRUPT files, but don't care about changed or missing files, you would set..
As one commenter (below) pointed out, with this sort of functionality, checksum would become "the only tool against silent data corruption". I believe this goal has now been achieved.
The chosen algorithm is also stored along with this information, for possible future use (aye, more algorithms!).
Automatically remove hashes for missing files..
Stuff gets deleted, on purpose; fact of computing life. When verifying your hashes, you can have checksum remove those entries from your
.hash file automatically, so you never have to think about them again!
The number of deleted hashes, if any, is posted in your final notification.
Automatically update hashes for changed files..
Files gets mindfully altered; another fact of computing life - MP3's get new ID3 tags, documents get edited, and so on. Now you can have your hashes updated, too! That's right! During verification, you can instruct checksum to automatically update (aka. "refresh") those entries (and their associated timestamps) inside your
.hash file. No more editing required!
The number of updated hashes, if any, is also posted in your final notification.
Effortless hashing of read-only volumes..
checksum can create BLAKE2, SHA1 and MD5 hashes for the read-only volume, but store the checksum files elsewhere; either with relative paths inside; so you can later copy the checksum file into other copies of the volume, or absolute paths; so you can keep tabs on the originals from anywhere.
checksum currently has three different read-only fall-back strategies to choose from; use whichever most suits your needs.
Extensive logging capabilities, with intelligent log handling and dynamic log naming..
checksum always gives you the option to log failures. But you can log everything if you prefer. hashing times can be included in the logs, and proper CSS classes ensure you can tell what's-what at a glance.
Relative or absolute log file path locations can be configured in your preferences, as can the checksum log name itself; with dynamic date and time, as well as dynamic location and status tokens, so you can customize the output naming format to your exact requirements.
In other words, as well leaving it to checksum to work out automatically, or typing a regular name into your prefs, such as "checksum.log", you can use cool
@tokens to insert the current..
@sec... seconds value. from 00 to 59
@min... minutes value. from 00 to 59
@hour... hours value, in 24-hour format. from 00 to 23
@mday... numeric day of month. from 01 to 31
@mon... numeric month. from 01 to 12
@year... four-digit year
@wday... numeric day of week. from 1 to 7 which corresponds to Sunday through Saturday.
@yday... numeric day of year. from 1 to 366 (or 365 if not a leap year)
There is also a special token:
@itemwhich is transformed into the name of the file or folder being checked, and
@status, which automatically transforms into the current success/failure status.
You can mix these up with regular strings, like so..
log_name=[@year-@mon-@mday @ @hour.@min.@sec] checksums for @item [@status!].log
@status strings can also be individually configured in your prefs, if you wish. Roll the whole thing up, and with the settings above, the final log name might look like..
[2007-11-11 @ 16.43.50] checksums for golden boy [100% AOK!].log
HTML logging with log append and auto log-rotation..
As well as good old plain text, checksum can output logs in lovely XHTML, with CSS used for all style and positional elements. With the ability to append new logs to old, and auto-transforming tokens, you setup automatic daily/monthly/whatever log rotation by doing no more than choosing the correct name. You can even have your logs organized by section and date, all automatically; via the free-energy from your
checksum can be instructed to run a program upon job completion. It can also pass its own exit code to the program.
Total cross-platform and legacy md5 file format support..
Work with hidden checksums..
If you don't like to see those
.hash files, no problem; checksum can create and verify hidden checksum files as easily as visible ones. Like most options, as well as on-the-fly configuration via the options dialog (hold down SHIFT when you launch checksum), you can set this permanently by altering checksum.ini.
To create hidden checksums (same as attrib +h), use "h" on the command-line, or choose that option from the options dialog.
Don't worry about creating music playlists with the invisible option enabled, the playlists will be perfectly visible, only the checksums get hidden! (well, someone asked! ;o)
Handy if you are making scheduled items, etc, and want to disable all dialogs and notifications. Simply add a 'q' (or check the box in the one-shot options).
You can also set checksum to only pop up dialogs for "long operations". Just how long constitutes a long operation, is of course, up to you. The default is 0, so you get "SUCCESS!", even if it only took a millisecond. Check your preferences for many more wee tricks like this.
"No-Lock" file reading..
checksum doesn't care is a file is in-use, it will hash it anyway! And it won't lock your files up while it's doing it. Feel free to point checksum at any folder.
Unrelated to the "quiet" option (above), checksum can thoughtfully invoke your PC speaker to notify you of any verification failures as they happen, as well as shorter double-pips on completion (if your PC supports this - many modern PCs don't). You can even specify the exact KHz value for the beeps, whatever suits you best.
You can also assign WAV files for the success and failure sounds, if you prefer. A few samples can be found here.
Drag-and-drop files, folders and drives onto checksum..
If you prefer to drag and drop things, you can keep checksum (or a shortcut to it) handy on your desktop/toolbars/SendTo menu, and drag files or folders onto it for instant checksum creation. This works for verification, too; if you drag a hash file onto checksum, its hashes are instantly verified.
Note: like regular menu activation, you can use the SHIFT key to pop-up the options dialog at launch-time. You can also drag and drop files and folders onto the one-shot options dialogs, to have their paths automatically inserted for you.
User preferences are stored in a plain text Windows® ini file..
You can look at it, edit it, back it up, script with it, and handle it. Lots of things can be tweaked and set from here, though 99.36% of people will probably find the defaults are just fine, and the one-shot option dialogs handle everything else they could ever need. But if you are a more advanced user, with special requirements, chances are checksum has a setting just for you. Click here to find out more about
Comprehensive set of command-line switches..
Normally with checksum, you simply click-and-go; but checksum also accepts a large number of command-line switches. If you are creating a custom front-end, modifying your explorer context menu commands, or creating a custom scheduled task or batch file, take a look at checksum's many switches. For lots more details, see here.
If you simply have some special task to perform, it can probably be achieved via the one-shot options dialog.
Shutdown when done..
If your system doesn't normally run 24/7, don't let that stop you from hashing Terabytes of data! checksum can be instructed to shutdown your PC at the end of the job.
That's a lot of features! And it's not even them all!
checksum is jam-packed with thoughtful little touches, you might even call it Artificial Intelligence! Wherever possible, if checksum can anticipate and interpret users, it will.
Legacy and cross-platform MD5/SHA1 file formats that checksum can handle..
If you look inside any MD5/SHA1 checksum file - it's plain text - you find all sorts of things.
Here's what a regular (MD5) checksum file looks like..
Each line begins with the MD5/SHA1 digest (hash), followed by a space, then an asterisk, then the filename. It's a clear format, flexible, relatively fool-proof ("*" is not allowed on any file system), and well supported.
Other formats I've come across..
single file single MD5/SHA1 hash types - these necessarily have the same name as the file, with ".md5" or ".sha1" extension added, and are often hand-made by system admins, or else piped from a shell md5/sha command) ..
space delimited hashes (before we figured out the clever asterisk)..
double-space delimited hashes (just silly, really)..
Believe it or not, this is the de-facto standard for md5 files, mainly because it's the output from the UNIX md5sum/sha1sum command in 'text' mode, which amazingly; is the default setting. By the way; md5sum's "-b" or "--binary" switch overrides this insanity.
TAB delimited hashes (I am assured these do exist!)..
back-to-front hashes in parenthesis - this is quite a common format around the UNIX/Solaris archives of the world (it's the output from
openssl dgst command) ..
MD5(01 - Stygian Vista (radio controlled).mp3)= 01805fe7528f0d98c
MD5 (01 - Stygian Vista (radio controlled).mp3) = 01805fe7528f0d98c
SHA1(01 - Stygian Vista (radio controlled).mp3)= 4988ae20125db8071
checksum supports verification of all these formats with ease, so feel free to point it at any old folder structure, Linux CD, whatever, or any .md5 or .sha1 files you have lying around, and get results.
And in case the above track names got you googled here, yes, checksum also works great in Microsoft® Vista, and Windows 7, Windows 8, Windows 8.1, and Windows Server of course, even XP! ;o)
Installed along with checksum is checksum's little brother app, "simple checksum", a supremely simple, handy, free, and highly cute drag-and-drop desktop checksumming tool utilizing checksum's ultra-fast hashing library; for all those "wee" hashing tasks..
