 ## Warning !
-The only goal of this library is to be integrated in [DroidFS](https://forge.chapril.org/hardcoresushi/DroidFS). It's not actually ready for other usages. libgocryptfs doesn't implement all features provided by gocryptfs like symbolic links creation, thread-safety, reverse volume creation...
