My laptop (Ubuntu 12.04) stopped mounting my encrypted home drive today after several months of working fine. I have been using the same login password since I set up the encrypted home drive a few months back with no issues.
/var/log/syslog is showing that it is an
Incorrect wrapping key for my wrapped passphrase. I figure this means that my wrap-passphrase file is corrupted and is no longer valid. I have my mount passphrase password from when I encrypted the home drive.
I booted from LiveCD and executed the following process:
root@ubuntu:/media/backup/home/me# ecryptfs-recover-private INFO: Searching for encrypted private directories (this might take a while)... INFO: Found [/media/backup/home/.ecryptfs/me/.Private]. Try to recover this directory? [Y/n]: Y INFO: Found your wrapped-passphrase Do you know your LOGIN passphrase? [Y/n] n INFO: To recover this directory, you MUST have your original MOUNT passphrase. INFO: When you first setup your encrypted private directory, you were told to record INFO: your MOUNT passphrase. INFO: It should be 32 characters long, consisting of [0-9] and [a-f]. Enter your MOUNT passphrase: INFO: Success! Private data mounted read-only at [/tmp/ecryptfs.COf2NZVr].
However, when I
cd to the
tmp folder (i.e.
cd /tmp/ecryptfs.COf2NZVr), all I see are encrypted files (
ECRYPTFS_FNEK_ENCRYPTED.F...). Based on the question/answer located under ecryptfs-recover-private creating unreadable encrypted folders, it appears they fixed this issue with using the login passphrase. However, as I already pointed out, my login passphrase is not working.
Since the mounted Passphrase is partially working (it allows me to mount up in
/tmp the files successfully) is there anything else I can do to get these files unencrypted? Any help would be appreciated.
