md5im-1.2.0.zip (68K) a zipped hfs disk image and checksum file. The disk image can be mounted with Mini vMac. Includes source code.

Md5Im is an application to use in Mini vMac (version 3.0.0 or later) to calculate or verify an md5 checksum of a file located on the real computer. (It combines the functionality of the Md5Fl and ImportFl applications.)

Note that there are numerous programs for various operating systems that will compute an md5 checksum, way faster than Md5Im can run in emulation. However, because there are so many, I'm not going to support any of them. (That is, I won't document using them, or answer questions about using them.) Md5Im will work identically on all computers that can run Mini vMac.

When Md5Im is the active application running in the emulated computer, then any of the methods normally used to mount a disk image will instead checksum a file. For example, dragging the icon of the file to be checksummed into the Mini vMac window.

warning: When attempting to use Md5Im, if you see a dialog asking if you want to initialize the disk, choose “Eject”, not “Initialize”! This will happen if Md5Im is not actually the active application, in which case the file you are attempting to checksum is treated as a disk image. Choosing “Initialize” will turn it into a valid disk image, destroying parts of the previous content.

The calculated md5 checksum will be displayed in Md5Im's window. The checksum will also be placed on the clipboard of the real computer (not the clipboard of the emulated computer). Before replacing the contents of the clipboard it will examine the old contents and see if matches the new value. If it matches, an "equals" sign is displayed on the right side of Md5Im's window. If it doesn't match, but the old content looks like an md5 checksum, then a "not equals" sign is displayed. Otherwise, if the old content doesn't look like an md5 checksum, no extra symbol is displayed.

For example, to verify the Md5Im zip archive, copy "4346163700a994edca6ac1588ed6d2e8" (not including the quotes) onto the clipboard of your real computer, run the Md5Im application in Mini vMac, and then drag the icon of the file "md5im-1.2.0.zip" onto the Mini vMac window. The Md5Im window should display "4346163700a994edca6ac1588ed6d2e8" followed by an "equals" sign.

Md5Im was created using md5 code from glibc-2.3.4, copyright the Free Software Foundation, and written by Ulrich Drepper.

The name "Md5Im" stands for "MD5 of IMported file".

Here is the md5 checksum for the download:
