Version: (using KDE Devel) Installed from: Compiled sources show md5, sha checksums in file properties dialog similar to bug #81258 but instead of verifying existing checksum files, konq should perform and display the checksum when the file properties window is shown.
I'm not sure this is a good idea, calculating the md5 for a big file is not a quick task.
I'm not saying it has to be done right when the window pops up. Instead, start another thread in the background with a progress bar like k3b does.
