Comment 4 for bug 1359776

You can create a new .encfs6.xml with these commands:
mkdir -p ~/tmp/plain
mkdir -p ~/tmp/enc
encfs --reverse ~/tmp/plain ~/tmp/enc
  - select x for expert modus
  - type 1 for AES
  - type 256 for key length
  - hit Enter for default blocksize
  - type 3 for stream-cipher
  - enter your new password twice

now you can copy the new .encfs6.xml to your destination drive and set up a new profile in BIT for this. Be careful not to override your existing .encfs6.xml as you will loose access to your current backup.

I prefer to keep default with block-cipher. This is a bug in encfs which I suspect to be fixed soon and I don't want to make users backups less secure in the meantime.
