May 10, 201610 yr I wrote about encFS many years ago on this forum and wanted to provide an update. A number of new alternatives have emerged and unRAID architecture has changed quite a bit. Block device encryption remain the fastest way to protect a hard drive especially if the CPU provides AES-NI instructions. Will unRAID be ever able to mount external dm-crypt encrypted USB drive used for backups? Now for NAS/unRAID storage and also Cloud storage a per file encryption is prefered and encFS has been around for quite some time but has never been perfect security and performance wise. I recently cam across a couple of new projects that aim to be an alternative to encFS such as : gocryptfs https://github.com/rfjakob/gocryptfs securefs https://github.com/netheril96/securefs I ran a simple benchmark on a desktop and a SSD and wanted to share it with the unRAID community. https://gist.github.com/alphazo/09a2e523e22e7aa00d491ab67678dd80
May 12, 201610 yr There is also ecryptfs which has some level of kernel adoption. It's what ubuntu (perhaps others?) use to provide encrypted homedirs etc I believe. It can behave in the same way as encfs (normal user, single directory) https://en.wikipedia.org/wiki/ECryptfs
