I am trying to use encfs in reverse mode. I understand that the passphase is used to encrypt a key which is then stored encrypted into the encfs6.xml file.

What I do not understand is the following.

  • Create en encrypted virtual fs of a folder by using passphrase A
  • unmount this folder.
  • Delete all contents including the encfs6.xml file

  • If you then try to do the same with another passphrse I would expect that a new encfs6.xml would be created. However I get the following error message:

"Error decoding volume key, password incorrect"

So I wonder, what volume key is incorrect, I thought it was in the encfs6.xml file ?
