Protect Data

[b._.o._.b]

Just tried to protect some files by encrypting them. I have never done that, and in ubuntu that is pretty easy.
Create a pgp file and you can use the file by entering a password and save the file.

Easy but not very usable. I would prefer a method that a folder is protected and not accessible and when you enter a password for the folder you are able to use the files.
Is something like this possible? I want to use the method on an already existing system, so don't want to add encryption into the filesystem (or this can be done very easily without breaking current setup).

I'm assuming you login as user X, so you could assign all folders and files in a folder as belonging to another user and have group and world rights removed. Then you need to login as that user to access the folder (or login as root).

It's not very secure however if someone has physical access to your machine or root access, so I'd use fuse-encfs. I know you don't want encryption, but it's the only safe way to go. Ubuntu already has Crypt Manager which should do all the work for you.

I would go for truecrypt, its quite strong.

Thanks guys. The standard file encryption on Ubuntu though very easy, is not what I'm looking for. Change user access is I also not what I want, I also want to protect my data in case I've lost a usb stick/drive or it is stolen.

Best would be on-the-fly encryption.
Should be possible with truecrypt. I've found this thread on Ubuntu forums http://ubuntuforums.org/showthread.php?t=1...rypt&page=6 will be fun to try it out. Not much info on fuse-encfs so I think will try truecrypt first.
