Subject: encryption metadata not stored with filesystem
Date: Mon, 19 Dec 2011 13:36:04 +0100 [thread overview]
Message-ID: <201112191336.05938.ms@teamix.de> (raw)
Hi!
On trying to work with ecryptfs I have found that I have to store ecryptfs
configuration in an undocumented file ~/.ecryptfsrc like:
merkaba:~> cat .ecryptfsrc
ecryptfs_unlink_sigs
ecryptfs_sig=[…]
ecryptfs_fnek_sig=[…]
ecryptfs_xattr
ecryptfs_key_bytes=32
ecryptfs_cipher=aes
ecryptfs_passthrough=n
in order to mount ecryptfs without mount options.
This makes handling of ecryptfs filesystem more complicated than encfs, since
encfs seems to store encryption metadata in the encrypted directory itself:
merkaba:~> ls -l /home/.ms2/.encfs5
-rw-r----- 1 root root 241 Mai 19 2008 /home/.ms2/.encfs5
Thus with ecryptfs I have to save the encrypted directory and the filesystem
settings for a backup while with encfs its enough to copy the encrypted
directory.
Please consider to add this feature in ecryptfs.
It will also make setting up ecryptfs easier.
Thanks,
