That's also a very good reason. Encryption is thought of as an add-on because the drives are rotated off-site. Since the drive are traveling, might as well add encryption. I ran some tests with dm-crypt and it's surprising how little overhead encryption incurs. In one instance, a 2GB copy to an encrypted partition was 1 second faster than to a regular partition (with machine reboots in between just to be sure no cache mechanism gets in the way). Add to that all the recurring news stories about laptops stolen or lost and some such involving lost data of various kind, encryption then makes a lot of sense. I guess there's no other way than having the password in clear text in a script. The script could be then be made readable only by root, everybody else gets a permission denied. That could perhaps suffice. Cheers, Al -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
