CryFS

CryFS encrypts your files, so you can safely store them anywhere. It works well together with cloud services like Dropbox, iCloud, OneDrive and others. See https://www.cryfs.org.

Install latest release

Easy install (Ubuntu and Debian)

wget -O - https://www.cryfs.org/install.sh | sudo bash

Manual install (Ubuntu)

# Add apt key
wget -O - https://www.cryfs.org/apt.key | sudo apt-key add -

# Add apt repository
sudo sh -c "echo \"deb http://apt.cryfs.org/ubuntu `lsb_release -s -c` main\" > /etc/apt/sources.list.d/cryfs.list"

# Install cryfs 
sudo apt-get update
sudo apt-get install cryfs

Manual install (Debian)

# Add apt key
wget -O - https://www.cryfs.org/apt.key | sudo apt-key add -

# Add apt repository
sudo sh -c "echo \"deb http://apt.cryfs.org/debian `lsb_release -s -c` main\" > /etc/apt/sources.list.d/cryfs.list"

# Install cryfs

GUI

If you want to use a GUI to mount your CryFS volumes, take a look at zuluCrypt. You can simply drag&drop your CryFS encrypted directory into the zuluMount application to mount it.

Building from source

Requirements

• Git (for getting the source code)
• GCC version >= 4.8 or Clang >= 3.5
• CMake version >= 2.8
• libcurl4 (including development headers)
• Boost libraries version >= 1.56 (including development headers)
  • filesystem
  • system
  • chrono
  • program_options
  • thread
• Crypto++ version >= 5.6.3 (including development headers)
• SSL development libraries (including development headers, e.g. libssl-dev)
• libFUSE version >= 2.8.6 (including development headers), on Mac OS X instead install osxfuse from https://osxfuse.github.io/
• Python >= 2.7

You can use the following commands to install these requirements

    # Ubuntu
    $ sudo apt-get install git g++ cmake libcurl4-openssl-dev libboost-filesystem-dev libboost-system-dev libboost-chrono-dev libboost-program-options-dev libboost-thread-dev libcrypto++-dev libssl-dev libfuse-dev python
    
    # Fedora
    TODO
    
    # Macintosh
    brew install cmake boost cryptopp openssl

Build & Install

1. Clone repository

   $ git clone https://github.com/cryfs/cryfs.git cryfs
   $ cd cryfs
   

2. Build

   $ mkdir cmake && cd cmake
   $ cmake ..
   $ make
   

3. Install

   $ sudo make install
   

You can pass the following variables to the cmake command (using -Dvariablename=value):

• -DCMAKE_BUILD_TYPE=[Release|Debug]: Whether to run code optimization or add debug symbols. Default: Release
• -DBUILD_TESTING=[on|off]: Whether to build the test cases (can take a long time). Default: off

Troubleshooting

On most systems, CMake should find the libraries automatically. However, that doesn't always work.

1. Boost headers not found

   Pass in the boost include path with

    cmake .. -DBoost_INCLUDE_DIRS=/path/to/boost/headers
   

   If you want to link boost dynamically (e.g. you don't have the static libraries), use the following:

    cmake .. -DBoost_USE_STATIC_LIBS=off
   

2. Fuse/Osxfuse library not found

   Pass in the library path with

    cmake .. -DFUSE_LIB_PATH=/path/to/fuse/or/osxfuse
   

3. Fuse/Osxfuse headers not found

   Pass in the include path with

    cmake .. -DCMAKE_CXX_FLAGS="-I/path/to/fuse/or/osxfuse/headers"
   

4. CryptoPP library not found

   Pass in the library path with

    cmake .. -DCRYPTOPP_LIB_PATH=/path/to/cryptopp
   

5. Openssl headers not found

   Pass in the include path with

    cmake .. -DCMAKE_C_FLAGS="-I/path/to/openssl/include"
   

Creating .deb packages

There are additional requirements if you want to create .deb packages. They are:

• CMake version >= 3.3
• (optional) rpmbuild

1. Clone repository

   $ git clone https://github.com/cryfs/cryfs.git cryfs
   $ cd cryfs
   

2. Build

   $ mkdir cmake && cd cmake
   $ cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=off
   $ make package
