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.

This repository contains the filesystem implementation. There are submodules in the following repositores:

• Blockstore: Store (encrypted) fixed-size blocks of data in different backends
• Blobstore: Store resizeable blobs of data using blocks from a blockstore
• ParallelAccessStore: Concurrency primitive for Blockstore/Blobstore
• Fs++: Implement a file system against a platform independent interface

Building from source

Requirements

• biicode

  # After installing, call
  $ bii setup:cpp
  

• GCC version >= 4.8 or Clang (TODO which minimal version?)

• CMake version >= 3.3

• libcurl4 (including development headers)

• libFUSE >= 2.8.6 (including development headers)

  # Ubuntu
  $ sudo apt-get install libfuse-dev
  
  # Fedora
  TODO
  
  # Macintosh
  TODO
  

Build

1. Clone repository

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

2. Build

   $ bii init -L
   $ bii configure -D CMAKE_BUILD_TYPE=Release
   $ bii build
   

3. (if build failed) Biicode can have a bug sometimes where the first call to configure fails. If that happens, just call it again.

4. Install

   $ cd bii/build/messmer_cryfs
   $ sudo make install
   

You can pass normal make parameters after a double dash. This can for example be used to add "-j5" to compile with 5 build threads in parallel:

    $ bii build -- -j5
