Hi all,
I've set up backups (using bacula) of my ecryptfs encrypted home directory (on lucid), and now I am checking that I can restore the filesystem. I've restored it from the backup onto a completely different server, so now I am trying to mount it.
Does anyone know what the default cipher and key bytes are, that Ubuntu uses when it first creates the encrypted filesystem? I know my passphrase is correct, so I'm not sure what I should be entering for the questions below in order to get it to mount.
Code:
mount -t ecryptfs /restore/home/.ecryptfs/paul/.Private /mnt
Passphrase:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
2) blowfish: blocksize = 16; min keysize = 16; max keysize = 56 (not loaded)
3) des3_ede: blocksize = 8; min keysize = 24; max keysize = 24 (not loaded)
4) twofish: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
5) cast6: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
6) 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]: y
Enable filename encryption (y/n) [n]: y
Filename Encryption Key (FNEK) Signature [xxxxxxxxxxxxxxx]:
Attempting to mount with the following options:
ecryptfs_unlink_sigs
ecryptfs_fnek_sig=xxxxxxxxxxxxxxxx
ecryptfs_passthrough
ecryptfs_key_bytes=16
ecryptfs_cipher=aes
ecryptfs_sig=xxxxxxxxxxxxxxx
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 [xxxxxxxxxxxxxxxx] 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.
Mounted eCryptfs
Thanks, Paul.
