http://www.howtoforge.com – Encrypt Your Data With EncFS (Ubuntu 12.10) EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Ubuntu 12.10 to encrypt your data. (HowTos)

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. EncFS is open source software, licensed under the GPL.

As with most encrypted filesystems, Encfs is meant to provide security against off-line attacks; ie your notebook or backups fall into the wrong hands, etc.

I would like to use Encfs to encrypt a copy of / for a backup. Whenever I do this through other tools, they have an option to not cross filesystems.

Is there an equivalent option in Encfs? Or would such attributes pass through to the encrypted version, and I should just run my backup tool with the one filesystem option?

Yesterday I’ve done an introduction to EncFS, a Free (GPL) FUSE-based cryptographic filesystem that transparently encrypts files, using an arbitrary directory as storage for the encrypted files. i’ve show how install and use it from the command line, but there is also an easier way to integrate it with your Desktop: Cryptkeeper.

I want to encrypt my filesystem with encfs, but I don't know how long my password should be.

I'm gonna be using AES 256, with blocks of 4096 bits.

How many guesses per second can I expect an attacker can make on files encrypted with that?

I'm worried that this might depend on the size of the smallest encrypted file.

Any thoughts?

Currently I'm using EncFS to encrypt my directory "confidential" to ".encconfidential" and sync that encrypted directory using an online service (e.g. Dropbox, UbuntuOne etc). However my entire disk is already LUKS encrypted, so the double encryption takes a toll on performance.

I wonder is there an "inverted" EncFS option?

Symlinks and EncFS 1 year 4 weeks ago

I am trying to secure my Dropbox account by using EncFS. My strategy is as follows:

I store all my files in a folder called ~/Public/. The encrypted counterpart of ~/Public/ is ~/Private/. Use EncFS: encfs ~/Private/ ~/Public/

Now the problem is that I'd like to use Dropbox for backing up my dotfiles as well. So I tried symlinking ~/.rc/ (the folder containing my dotfiles) into ~/Public.
