Client to use a free encrypted cloud based network file system

 An easy-to-use, easy-to-setup, hassle-free secure file system with the
 encrypted data being stored on a remote cloud server without having to
 trust the server.
 .
 All key material is created on the user's computer and never stored or
 transferred to the server.
 .
 All data is locally encrypted (including the file name). The encrypted
 data (and only that!) is stored in the cloud. The data remains secure even
 if the cloud server is compromised. It does not need root or superuser
 privileges. No need to run your own server. All you need is the bash
 script (literally). It is one single command to add and use a
 file system:
 .
 $ erfs mount aDe5F2ik3x35x7pfAEAWdC5Y ~/secure
