## 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... Use it at your own risk !
