I’m very grateful for your comments on the first version of DropSum, a little drag-and-drop utility to check MD5 and SHA-256 hashes of files. Following those I have made several improvements to the app, and am delighted to offer version 1.1.

For those who tried it before their first coffee of the day, if you drop an app or other folder onto it, it now politely informs you that it can’t compute hashes for it.

It has also gained a new toggle switch to enable/disable computation of the MD5 hash. Those are becoming increasingly uncommon, and by omitting that, DropSum can take as little as half the time to compute only the SHA-256 hash, which is the better of the two.

It has been redecorated in a different colour scheme so that its controls stand out better in all appearance modes, and its window is instantly recognisable.

The MD5 toggle makes it quicker to use for checking whether two files are identical. To do that,

1. toggle MD5 off,
2. click on the Clear button,
3. drop the first file onto its window,
4. drop the second file onto its window.

If the data for the two files is identical, and their SHA-256 hashes are the same, DropSum will display ✅. The app doesn’t compare their extended attributes, though, only the file data. For example, that will show two copies of the same file downloaded on different days are the same, although download details in their extended attributes are likely to be different.

When the MD5 toggle is set to off, its boxes are hidden.

DropSum 1.1 for Big Sur and later, including Tahoe, is now available from here: dropsum11
and from its Product Page.

For the record, here are its hashes, as computed by DropSum:

• MD5 21fadab0eba02c96b8ad2f06c7295021
• SHA256 97c2d1bfd8122f364b54cc301a5e9ef4c5578312eca4ce14c810743846aeb2f6

Enjoy!
