This app works with: SheepShaver, Basilisk II, Mini vMac

Here is Checksum 1.3 - a utility allowing you to check the MD5sum of downloaded files via a Classic Mac.

Any Mac that can run a Mac OS from version 6 through to 9.2.2 that is!

MD5 checksum & file name: e63a76b937006f44a26ec2a7042f4ef0 *Checksum_0_0.sit

Hint: On your first time use of Checksum 1.3 to match an MD5 Checksum: Under Options menu, uncheck everything except for RSA MD5 and Data fork (see image 3 of 4 this page) then go File menu Open and navigate to the location of the file you want to check, select and [OK] to run your checksum.

Checksum 1.3 will remember your last used settings. Supports drag and drop (on Macs that support "Macintosh Drag & Drop") and can do batch checksumming of folder contents.

Free for personal and educational use - Enjoy.

Architecture: 68k

Runs on Mac Plus through to G4, also Mini vMac, Basilisk II and SheepShaver.

If "drag & drop" does not appear to work for you with Checksum 1.3, you should try rebuilding your desktop database files, i.e; Start up or Restart your Mac with the "Option" & "Command" keys held down until the Mac boots up and presents you with a dialog window asking if you wish to "Rebuild the Desktop" of your hard drive[s], click [OK]. You should be able to drag files onto Checksum's icon to automatically launch and obtain a checksum after doing this.

It is an easy program to use, and for a Classic Mac, the only one I know of that does MD5 checksumming (there may be others but I don't know of them offhand).

On Mac OS X tho', I use the built-in MD5 checksummer via Terminal. Its also very easy to use and faster than starting Classic (if you have Classic). Terminal command is: md5(+ a space) drag icon of file to check into Terminal window after the space (to get filename and PATH to it into Terminal) and hit "enter" or "return" key.

A very easy program to use, and it works well in Classic Mode. Everyone who uploads critical software, such as System Software, should consider taking the couple of extra minutes to perform/add a checksum along with the upload. Smile

The archived file should return the MD5 checksum:
