# CryFS [](https://circleci.com/gh/cryfs/cryfs/tree/next)
|
|
|
|
**TODO:** Update CI link to correct branch when merging next->develop or develop->master
|
|
|
|
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](https://www.cryfs.org).
|
|
|
|
Install latest release
|
|
======================
|
|
|
|
This only works for Ubuntu 17.04 and later, and Debian Stretch and later.
|
|
You can also use CryFS on older versions of these distributions by following the **Building from source** instructions below.
|
|
|
|
sudo apt install cryfs
|
|
|
|
GUI
|
|
===
|
|
Theres some GUI applications with CryFS support. You usually have to install the GUI **and** also CryFS itself for it to work.
|
|
- [SiriKali](https://mhogomchungu.github.io/sirikali/)
|
|
- [Plasma Vault](https://www.kde.org/announcements/plasma-5.11.0.php) in KDE Plasma >= 5.11
|
|
|
|
Building from source
|
|
====================
|
|
|
|
Requirements
|
|
------------
|
|
- Git (for getting the source code)
|
|
- GCC version >= 4.8 or Clang >= 3.7
|
|
- 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 make 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
|
|
sudo dnf install git gcc-c++ cmake make libcurl-devel boost-devel boost-static cryptopp-devel openssl-devel fuse-devel python
|
|
|
|
# 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
|
|
- **-DCRYFS_UPDATE_CHECKS**=off: Build a CryFS that doesn't check online for updates and security vulnerabilities.
|
|
|
|
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 and .rpm packages
|
|
-------------------------------
|
|
|
|
There are additional requirements if you want to create packages. They are:
|
|
- CMake version >= 3.3
|
|
- rpmbuild for creating .rpm package
|
|
|
|
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
|
|
|
|
|
|
Disclaimer
|
|
----------------------
|
|
|
|
On the event of a password leak, you are strongly advised to create a new filesystem and copy all the data over from the previous one. Done this, all copies of the compromised filesystem and config file must be removed (e.g, from the "previous versions" feature of your cloud system) to prevent access to the key (and, as a result, your data) using the leaked password.
