mounts or creates an encrypted virtual filesystem

--reverse
    Normally EncFS provides a plaintext view of data on demand.  Normally it stores enciphered data and
    displays plaintext data.  With --reverse it takes as source plaintext data and produces enciphered
    data on-demand.  This can be useful for creating remote encrypted backups, where you do not wish to
    keep the local files unencrypted.

    For example, the following would create an encrypted view in /tmp/crypt-view.
