easy md5sum generation
Last modified: 2007-01-20 17:51:21 UTC
There should be a button allowing user to generate and verify file's md5 (and others) checksum. Look at this extension for MS Win: http://www.beeblebrox.org/hashtab/
This is a great project for one of nautilus' scripting interfaces, there here should work. http://g-scripts.sourceforge.net/cat-fileproc.php
IMHO modern operating system (and desktop environment) should provide easy way of verifying files' checksums out-of-the-box. Please don't tell that it's already available from shell. I really know about it, but it's not a solution for typical users.. Also, installing of external scripts is not what typical users wants to do...
Thats not what I'm trying to say, I'm saying, the infrastructure for such a system exists already. I'm not a nautilus developer, so I won't weight in on why or why not, just a how.
You can achieve this by installing Nautilus Actions (http://www.grumz.net/index.php?q=node/8) and the Generate Checksums (http://www.grumz.net/?q=node/249) and Verify Checksums (http://www.grumz.net/?q=node/250) actions.
