![]() You will be presented with two standard configuration options, standard and paranoid, and an expert option. Assuming an existing folder called MyFolder and you want an encrypted folder called MyFolderEnc, try this: $ encfs -reverse MyFolder MyFolderEnc This is the opposite of storing the files in encrypted form and providing an unencrypted view, hence "reverse encryption". This creates a folder that acts as an encrypted view of another folder, where the encrypted data is provided on the fly from the unencrypted files. Configure reverse encryptionĮncFS has an option to do "reverse encryption". If there is such an icon there, open it and press the "Remove" button before trying to install again. Note: If you're having trouble installing osxfuse, check if you already have it installed by looking for a "Fuse for OS X" icon in "System Preferences". Type encfs -v to verify EncFS is available. ![]() Just follow the instructions provided by Homebrew to manually install osxfuse, then do brew install encfs again. This is because Yosemite (and later OS X versions) require all kernel extensions to be signed, and Homebrew doesn't do binary signing at the moment. If you are running OS X 10.10 or later you'll get an error about having to manually install osxfuse. Installing EncFS is simple: $ brew install encfs $ ruby -e "$(curl -fsSL )"įollow the instructions, and then you are ready to brew. Paste the following into a terminal (or copy it from the Homebrew website if you are cautious/paranoid). Open Terminal and type the following: $ xcode-select -installįollow the instructions in the popup dialog, and after that you won't have to worry about Xcode again. They are provided in the Xcode app bundle, and can be quickly installed from the command line. Next you need to install the Xcode command line tools. Open Xcode and accept any license agreements that pop up, then quit Xcode. Many Homebrew formulae require Xcode for compilation, so go to the AppStore and install Xcode. The easiest way to get started is to install EncFS with Homebrew. Note: This article assumes you know your way around a Terminal window, and it will be easier to follow if you know a thing or two about bash scripting (bonus points for expect/tcl knowledge). Encrypted archives or disk images can be used and are easy to setup, but another option is to use EncFS to create an encrypted view of some part of your filesystem. ![]() You can however work around this problem by encrypting the backup before uploading it to the storage provider. ![]() If you want full privacy you have to be able to supply your own encryption key, and very few cloud storage providers have that option. In order to provide services like file sharing and media preview they have to use an encryption key that they control on their end, which means they can decrypt your data. Using a file synchronization and backup service in the cloud like JottaCloud or Dropbox for backups is convenient, but not as secure as you might think.
