Other Projects
==============

There are several open-source file encryption solutions available.
This page tries to help to find the right one for your use case:

* [gocryptfs](https://nuetzlich.net/gocryptfs/) (this project), aspiring successor of EncFS
* [EncFS](https://github.com/vgough/encfs), mature with known security issues
* [eCryptFS](http://ecryptfs.org/), integrated into the Linux kernel
* [Cryptomator](https://cryptomator.org/), strong cross-platform support through Java and WebDAV

If you spot an error or want to see a project added, please
[file a ticket](https://github.com/rfjakob/gocryptfs-website)!
