![]() ![]() This ability means that a file can actually be stored on more than one server. ![]() Users can set up a grid - a collection of servers - for storage use. However, what makes Tahoe stand out is its ability to decentralize files. It includes no option for not encrypting files, as well as options for working with Tor. To start with, Tahoe automatically encrypts all files with its a 2000-bit RSA public key. ![]() Basically, Tahoe is designed to give the cloud storage provider as little control over your data as possible The name is short for “Least Authority FileSystem,” a reference to a classic principle. Tahoe-LAFS provides the most comprehensive solution. However, if you prefer desktop apps, you are more likely to favor Cryptomator.įigure 2: Cryptomator has a graphical interface that makes encryption accessible to all. If you want some control of the encryption process, you are likely to prefer EncFS. Whether you prefer EncFS or Cryptomator depends on your habits. As with EncFS, a vault placed in the local directory for a storage provider like Dropbox will be uploaded to the cloud when users sync. All files added to the vault are encrypted automatically. Returning to the opening window, users can open a vault and use the system’s file manager to copy files to the vault. Naturally, the first time Cryptomator runs, a vault must be created by giving a path and a password. The main difference is some of the jargon - for example, in Cryptomator, encrypted directories are “vaults.”Ĭryptomator’s window opens with the option to create a vault or open one. The workflow for Cryptomator is structured much the same as EncFS. This problem seems to have been addressed in the Testing repository version in the Testing repository, so use that one.įigure 1: EncFS’s expert mode explains itself well enough that most users should be able to work with it. As well, when you install the version of EncFS in Debian “stable,” a note from 2014 warns that it is vulnerable to attacks from users with read and write access to the files, including lowering the encryption complexity and using timing analysis. Note, however, that EncFS does not guard against the provider moving or deleting files. Files added to the /Private directory will automatically be added to ~-Dropbox/-encrypted. The next time users sync with the online storage on Dropbox, the encrypted directory will be added to it. Alternatively, you can skip answering the questions by running the command with the -standard option, which uses predefined settings. The expert questions are clearly explained, so even a novice should have no trouble answering them, if only by accepting the default. You can start with the default paranoia mode by pressing the p key or the expert mode by pressing x and making the choices for encryption manually. The command sets up the encrypted directory by asking a series of questions. This command creates the directory for encrypted files in the home directory and another directory for the unencrypted files. For example, with Dropbox, the command to set everything up would be: encfs ~/Dropbox/encrypted ~/Private It can create remote virtual filesystems as easily as local ones if you are using a storage site that syncs a remote directory with a local one. EncFSĮncFS is used generally to create encrypted virtual filesystems. As two of the names suggest, each of these treats the online storage as a virtual filesystem, although the quality of them varies considerably. In Linux, three of the most usable tools for this purpose are EncFS, Cryptomator, and Tahoe-LAFS. However, these solutions also require trust - they only shift the trust requirement to a third party, and basic security requires the user to verify security for themselves.Ī better solution is to use open source tools to encrypt files before they are placed in online storage. Numerous tools exist for encrypting in the cloud. Fortunately, security can be regained by users storing only encrypted files. However, the convenience of cloud storage is too great for many companies and individuals to avoid it. The trouble is, it relies on the ability of users to trust the provider, yet often the only assurance available is the provider’s word. From a security perspective, cloud storage ought never to have happened. ![]()
