Some thoughts and initial observations about the FUSE-powered userspace Encrypted Filesystem, EncFS:

  1. A filesystem created with encfs version 1.2.5 (the version in Debian unstable) can be read with 1.2.0 (the version in Debian stable)
  2. You can't copy one of the encrypted files into a different encfs directory, even if the two directories were protected by the same passphrase. You need the .encfs5 file.
  3. You can burn an encfs back-end directory onto a CD or DVD and decrypt the files later, but filename limitations imposed by the ISO format are made more severe by encfs (you definitely need joliet and/or rockridge extensions)
