I have an old Lacie 5big NAS that does not support encryption. It speaks SMB, AFS and FTP.
I'm looking for a way to store encrypted data on the NAS, at the same time it should be accessible by multiple users.
Some of the users use Linux, some use Windows. Some may use Mac OS X but that's considered less critical for now.
Is there a solution? Can encfs work with a multi-user setup? Truecrypt containers will only work read-only.
