Status in “ecryptfs-utils” source package in Ubuntu: Fix Released
Bug description:
Binary package hint: ecryptfs-utils
- ecryptfs-utils_73-0ubuntu6 with Jaunty
- ecryptfs-utils_75-0ubuntu1 with Karmic
Trying to discover data from a crashed system with encrypted home-directory, it is recommended to use:
sudo mount -t ecryptfs /home/<username>/.Private /home/<username>
But after inserting the passphrase and answering the shown options, the volume is mounted to the given mount-point - but the name of files - and volumes are still encrypted, The content is partly readable.
It seem to me. the following is running wrong -> On a healthy system you will find inside /etc/mtab:
"ecryptfs_sig=14140887552e0bec,ecryptfs_fnek_sig=de5d090606c60111,ecryptfs_cipher=aes,ecryptfs_key_bytes=16", with different _sig values
but on a broken system after using above command both values are the same
"ecryptfs_sig=14140887552e0bec,ecryptfs_fnek_sig=14140887552e0bec,ecryptfs_cipher=aes,ecryptfs_key_bytes=16", independent of choosing (y/ n) for plaintext as well for foldername decryption (y/n).
These have been testet and verifyed with Jaunty and Karmic - both the same results.
