CHECKSUM Description
True point-and-click hash creation and verification.
No-brainer hash creation and verification. In a word; simple.
Choice of MD5 or SHA1 hashing algorithms.
Create a regular MD5sum (128-bit), or further increase security by using the SHA1 algorithm (160-bit). checksum recognizes and works with both 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!
Multiple user-defined file mask groups.
For instance, hash only MP3 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. reports-*.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 playlist files (Winamp, etc.), checksum also supports .pls playlists (shoutcast/icecast). Your call.
Effortlessly handles all known** legacy md5 files.
If you discover an MD5sum that checksum doesn't support, send me that file!
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.
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 hashes just for fun; worry not; checksum will work it out!
Can be configured to 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, desktop.ini files, thumbs.db, whatever; it's easy to setup. The most common annoying file types already are.
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 and sha1 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.txt, foo.htm, and 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!
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.
Effortless hashing of read-only volumes.
checksum can create 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 fallback 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: @item which 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
The @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 @tokens.

Total cross-platform and legacy md5 file format support
MD5 and SHA1 hash files from UNIX, Linux, Mac and Solaris, as well as a myriad of legacy Windows and DOS MD5 formats, in fact, every hash file I've ever come across, is supported. Throw any old MD5sum at checksum, and you'll get results. And if you don't (*gasp*), Send Me That FILE!
Work with hidden checksums.
If you don't like to see those checksum 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)
"Quiet" operation.
Handy if you are making scheduled items, etc, and want to disable all the dialogs. Simply add a 'q'.
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 ini for more wee tricks like this.
Audio alerts.
Unrelated to the "quiet" option (above), checksum can thoughtfully invoke your peecee speaker to notify you of any verification failures as they happen, as well as shorter double-pips on completion. 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.
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 checksum.ini
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, take a look at checksum's many switches.
If you simply have some special task to perform, it can probably be achieved via the one-shot options dialog.
