Mount .ecryptfs file

[topher83]

Hi

I recently had a VHD file go corrupt on a VirtualBox VM running ubuntu
I have managed to run a recovery program and got a load of files from this however the home directory was encrypted
I have a few .ecryptfs files from the recovery and I know the password used however I am unable to recover the data (Not really sure if im doing it right)

-----------------

sudo mkdir /mnt/crypt
sudo mount -t ecryptfs b13600744.eCryptfs /mnt/crypt
Passphrase:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (loaded)
2) des3_ede: blocksize = 8; min keysize = 24; max keysize = 24 (not loaded)
3) cast6: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
4) cast5: blocksize = 8; min keysize = 5; max keysize = 16 (not loaded)
Selection [aes]:
Select key bytes:
1) 16
2) 32
3) 24
Selection [16]:
Enable plaintext passthrough (y/n) [n]:
Enable filename encryption (y/n) [n]: y

ecryptfs_sig=fbc2d5c3151701c4
WARNING: Based on the contents of [/root/.ecryptfs/sig-cache.txt],
it looks like you have never mounted with this key
before. This could mean that you have typed your
passphrase wrong.

Would you like to proceed with the mount (yes/no)? : yes
Would you like to append sig [fbc2d5c3151701c4] to
[/root/.ecryptfs/sig-cache.txt]
in order to avoid this warning in the future (yes/no)? : no
Not adding sig to user sig cache file; continuing with mount.
Error mounting eCryptfs: [-20] Not a directory
Check your system logs; visit <http://launchpad.net/ecryptfs>

-----------------

Im either going the wrong way about mounting a .ecryptfs file given only the passphrase or somethings wrong with the way im mounting the file

Can anyone point me in the right direction

Thanks

And the kern.log says

Hi topher83,

I have a similar problem, could you find a way to read or decrypt .ecryptfs files ?

Best regards.
