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
2015-12-17 19:49:06 +01:00
======================
2018-01-13 00:22:24 +01:00
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.
2015-12-17 19:49:06 +01:00
2017-09-30 07:17:34 +02:00
sudo apt install cryfs

GUI
===
2017-11-23 02:56:01 +01:00
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

2016-02-12 10:16:38 +01:00
Build & Install
---------------
2015-09-29 15:47:05 +02:00
1. Clone repository
2016-02-11 19:58:55 +01:00
$ git clone https://github.com/cryfs/cryfs.git cryfs
2015-09-29 15:47:05 +02:00
$ cd cryfs
2. Build
$ mkdir cmake && cd cmake
$ cmake ..
$ make
3. Install
2015-10-26 20:44:00 +01:00
$ 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
---------------
2016-02-12 10:16:38 +01:00
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:
2016-02-17 01:19:20 +01:00
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"
2018-05-19 21:42:35 +02:00
4. **Openssl headers not found**
Pass in the include path with
2016-02-15 18:12:23 +01:00
cmake .. -DCMAKE_C_FLAGS="-I/path/to/openssl/include"
2016-02-15 18:07:24 +01:00
2016-02-12 10:16:38 +01:00
Creating .deb and .rpm packages
-------------------------------
2016-02-12 10:16:38 +01:00
There are additional requirements if you want to create packages. They are:
2016-02-12 10:16:38 +01:00
- CMake version >= 3.3
- rpmbuild for creating .rpm package
2016-02-12 10:16:38 +01:00
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
2016-09-19 23:48:05 +02:00
Disclaimer
----------------------
2016-09-22 20:17:05 +02:00
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.
