Just mount a file on a loopback, encrypt it with LUKS/dm-crypt and put that file on DropBox. I find it very convenient to have a stacked filesystem that can grow as needed (as opposed to pre-allocated block encryption). rsync of the underlying files). Even when it is, IO is not intensive so the performance hit from using FUSE has not been an issue. eCryptfs has been derived from Erez Zadok's Cryptfs. Just want input. Last edited by Redsandro (2013-01-18 20:50:01). The basic passphrase mode of operation provides equivalent func-tionality to that of EncFS[23] or CFS[20], with the … Then, after formatting my internal hard drive, I needed to access data on my encrypted folder. Just want opinions/experiences on whether I should use eCryptFS or encfs to get the job done. What can not be trusted is remote locations and portable storage. Until yesterday everything has always gone fine. Cryptsetup in sudoers is one step in the clever direction, but it still queries the kernel keyring, and I still have to add key/sig on reboot? zuluCrypt can also encrypt stand alone files (zuluCrypt menu -> zC -> encrypt a file). Is somehow possibile to migrate it to EncFS without re-encrypting it and thus without re-upload it to Dropbox? My Recommendation for ecryptfs. Anyway, LUKS doesn't provide the benefits I am looking for because it's disk-based.Looking for: File-based enctyption where I can just copy files on usb/smartphone/email and use them on a different location, File-system indendent, so no NTFS/EFS, ZFS or something stored in LUKS, loop or sparse files like TrueCrypt, Files not depending on anything (e.g. If your home partition can be physically trusted then there is no need to encrypt it. The keychain is safely locked away in my encrypted home, which can be physically trusted anyway. Ecryptfs isn't much better, according to some blogs the head developer left Canonical/Ubuntu and they have major problems adapting it to the latest Ubuntu releases, hence they dropped it in favour of LUKS/LVM in 19.04. EncFS needs config files in place). From: Dan Re: Ecryptfs vs encfs. Thus you cannot gather meta data of the underlying files, like size, a/c/mtime, directory structure etc. The problem with eCryptfs seems to be that it requires either root or fstab entries (which in turn require root). That protects data when the system is down, but when it's up it provides no protection whatsoever. encfs(1) - Linux man page Name. The keychain is safely locked away in my encrypted home, which can be physically trusted anyway. FYI, this script enables mounting ecryptfs folders without root access or touching the fstab: I may have misunderstood how that script works, but I believe that ecryptfs-simple does the same thing more efficiently. 1. eCryptfs. Is that what you're referring to? LUKS, full-disk encryption, is a better solution when no data at all is acceptable to leak outside of encrypted areas. When you say "full-disk-encryption", do you mean full system encryption? "recently used") will store them in both cases, so there is no difference there. Run the following command to create a new EncFS encrypted volume: This creates two directories. It is not secure. eCryptFS is a kernel module, while EncFS uses FUSE. Everything but /boot encrypted and using a device mapper to mount them. eCryptfs vs EncFS for subdirectories of $HOME. I did a talk about encrypted filesystems a month ago at the Chemnitzer Linux-Tage and looked deep into the details of encfs, gocrypts, cryfs and ecryptfs. This way you only have to remember the passphrase because all the other metadata is stored in the configuration file. -edit-I guess in theory I want to store the key in my user keyring, and copy it to the kernel keyring when I log in. I want to be able to use LVM to resize individual home partitions for a multi-user setup. 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 goes so far as to disclose it when you start up the encfs cli utility to ensure their users (new and old) are informed which is how I found out. In that case, I understand your point. EncFS provides an encrypted filesystem in user-space. I was under the assumption that you cannot. (C code using the ecryptfs library vs a lot of Bash subshells and shuffling). Ecryptfs is tied very close to Ubuntu and currently getting phased out by them. Hi all. The problem with eCryptfs seems to be that it requires either root or fstab entries (which in turn require root). As for the remote storage, I have a server running ownCloud but everyone agrees their remote encryption is very insecure. It's also a PITA to setup Ecryptfs, when it is not done by Ubuntu during installation. That's wrong, encfs does not split files. Encrypted data can only accessed by authorized parties while those who are not authorized cannot access it. There is also the issue of meta-data being generated off of your encrypted data into areas of the file-system which are not encrypted. I use encfs to backup my data to my external hard drive. The files can therefore be decrypted as long as they exist, whereas EncFS files depend on an extra file that could be lost (unlikely with proper backups, but still possible). That's handy info. It has highest performance and security. zuluCrypt is currently Linux onlyand it does hard drives encryption and it can manage PLAIN dm-crypt volumes, LUKS encrypted volumes, TrueCrypt encrypted volumes, VeraCrypt encrypted volumes and Microsoft’s BitLocker volumes. It is not secure. What can not be trusted is remote locations and portable storage. From: Dan Re: Ecryptfs vs encfs. If that script is only accessibly by your account and never uploaded to remote storage then it would achieve the same level of security, no? As for the rest of of your remarks, disk-based vs file-based encryption have different uses and are not interchangeable. It was written becauseolder NFS and kernel-based encrypted filesystems such as CFS had not kept pace with Linuxdevelopment. Don't really need help with the technical aspect. As I understand it, you just want to automate mounting of the encrypted directory locally without the passphrase prompt. I have not tried it myself, but it is possible thinly provisioned LVM LVs containing LUKS partitions would also be a solution to your problem. – Dustin Kirkland 19 gen. 12 2012-01-19 02:03:13 Thanks! A attacker may be able to gather the names of the files themselves in a situation like that and even that may not be acceptable to you. As for mlocate, /etc/updatedb.conf can be use to ignore ecryptfs and fuse.encfs so that these files are not tracked. Last edited by hunterthomson (2013-01-20 07:07:35). I created a 1.2GB file to get an idea of how long it would > take to write/read using ecryptfs vs non-ecryptfs on an ext3 file > system. You should not use eCryptfs. Anyway, apart from opinions, I take that you have no answer to my question? Obviously the system files need to be accessible for the system to be usable, but users may have sensitive data that they prefer to make accessible (i.e. [citation needed] As for the rest of of your remarks, disk-based vs file-based encryption have different uses and are not interchangeable. Using block encryption is not as versatile (fixed size, complicated backups) but I avoid double-encryption overhead and the hassles of using ecryptfs differently from the developers. Personally, while I like the simplicity of EncFS, I recommend eCryptFS. I thought, if so many distro's use it as a default, there's gotta be something to it.I want to use a long passphrase, that's why I need it in my keychain permanently. The files can therefore be decrypted as long as they exist, whereas EncFS files depend on an extra file that could be lost (unlikely with proper backups, but still possible). I recommend gocryptfs, it's pretty fast, follows the same principles as encfs and uses modern cryptography. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. Hence the long passphrase. But, I've decided that stacked filesystem encryption is better suited to my needs for my home directory, which is stored on a 7200 RPM HDD. In the question "What are the best encryption tools for Dropbox, that support easy sharing?" Don't take my word for it. 2. Press question mark to learn the rest of the keyboard shortcuts. But ecryptfs wants your passphrase to be in the kernel keyring. Cosa sia meglio, non saprei... bye, -- … 2. It is not a clever step it is what sudo is for. Does eCryptfs work like how Encfs does ? From a neutral point of view, you should consider that per-file encryption of eCryptfs may slow down low-performance hardware but allows a great level of flexibility, making the encryption process optional for your users and reversible without formatting if you need to change the MBT layout. I think what you may be looking for is a keyfile stored on a USB stick. I want to use a long passphrase, that's why I need it in my keychain permanently. I basically just want to be able to use eCryptfs the same way I can use EncFS. So I highly recommend it. Well first of all. The Private folder in your home folder is where the decrypted versions of your files will be ac… Certainly, it's easy (and even desirable) to combine the two. Ecryptfs vs encfs. It's basically the successor to encfs and fixes (or avoids) almost all of encfs issues. I used an old Lucid (10.04) install to mount my encrypted folder (was using 12.04 on my PC and it was the only available Linux install around) New comments cannot be posted and votes cannot be cast, More posts from the linuxquestions community, Press J to jump to the feed. ... My Rec ommendation for ecryptfs. I second this. Encfs development begun in 2003, when cryptographic standards weren't as developed as they currently are. After running: And then saving a file from Geany into /home/user/secret-dir . Ubuntu, Fedora, OpenSUSE all use LUKS/dm-crypt now. Last edited by Redsandro (2013-01-19 13:56:14). Additionally, if I've understood it correctly, the metadata is stored in the files themselves instead of EncFS's per-directory configuration file (.encfs6.xml). It runs in userspace,using the FUSE library for the filesystem interface. zuluCrypt can manage encrypted volumes that are hosted in image files, lvm, mdraid, hard drives, usb sticks or any other block device. I was looking for a way to make a simple arbitrary ecryptfs less rocketsciency and google redirected me to this topic. Anyway, distros use ecryptfs and LUKS/dm-crypt by default because they are in the mainline kernel. Yes, however with file-based encryption all the data in leaked as soon as you decrypt the file. Then everything can be automated. But the next day (aka after reboot) you have to add the key to the kernel ring all over again, making this unconvenient. You could only decrypt the file to like a ramdisk or tempfs to solve that problem. Things like mlocate. Nevertheless, I like the idea of using eCryptfs as it is supposedly faster and seemingly enjoys more widespread support. I confused ecryptfs with cryptoloop. https://www.youtube.com/watch?v=MPEKX3WE-VI, Last edited by hunterthomson (2013-01-20 06:20:21). But it comes with a penalty in speed, cryfs can become very slow for certain use cases. An obvious one would be if your swap partition wasn't encrypted and sensitive information was paged out to it and an attacker had access to your machine at a later time - even when the /home information was not unlocked. The encrypted files are not accessed very often so the directory is usually not mounted. Yes always use a long passphrase and change your passphrase about every month or better. Gocryptfs uses the same ideas as encfs but with much better cryptographic primitives. @3pic of course, he is one of the authors and maintainers of eCryptfs. I am generally used to encrypting entire block devices with Luks/cryptsetup, which is what I did to my boot drive. You can create a precomputed hash lookup table for cryptoloop. From: Dan Prev by Date: Re: wmv locks entire system ever since upgrade to 6.0.1; Next by Date: Re: libxaw7-dev busted, not sure why; Previous by thread: Ecryptfs vs encfs Add Video or Image. I'm not marking this as solved yet because I still think there's a way to do what I want, but I just can't spend any more time on trying to figure out how. The user has to weight convenience against security and performance, and it very much depends on expected usage. EncFS è un software molto semplice e intuitivo per la crittografia del disco Linux. The gocryptfs documentation has an overview of some virtual encrypted file systems: https://nuetzlich.net/gocryptfs/comparison/. It has been implemented as a stackable file system and provides filesystem-level encryption. Again, I am not really sure I know what you want. You boot and right after grub you enter your password in the console then it unlocks everything else and finishes booting. What kind of security would encryption provide if no key is needed to decrypt it? Riguardo encfs vs. ectryptfs, un'altra differenza (almeno, quando li provai io), e` che encfs ha la chiave in un unico file, mentre ecryptfs aggiunge un header ad ogni file. Side note: although I loved to use Truecrypt it shouldn't be on any comparison list due to the developer going AWOL and releasing a version with a panicked message stating Truecrypt is insecure leaving a lot of speculation. Will the unencrypted file be … Encfs is available on multiple platforms, whereas ecryptfs is tied very close to Ubuntu and currently getting out.
