Hi List,
I am using ecryptyfs to store some sensitive data in my PC (Debian
wheezy). The data is in a partition and the partition is mounted
automatically on bootup using /etc/fstab I have setup
/root/.ecryptfsrc with correct parameters. Contents of my .ecryptfsrc
are as follows:
key=passphrase:passphrase_passwd_file=/mnt/usb/password.txt
ecryptfs_sig=deadbeefdeadbeef
ecryptfs_cipher=aes
ecryptfs_key_bytes=16
ecryptfs_passthrough=n
ecryptfs_enable_filename_crypto=n
This partition is correctly getting mounted after a system reboot. So far fine.
I also need to transport this sensitive data to a remote place in a
USB drive securely. So I want to format a usb drive with ext2 fs and
mount it using ecryptfs. I also do not want to reuse the password and
want to give an one time password to each USB drive when the ecryptfs
is mounted.
Formatting and mounting of ext2 partition works as expected. The
command I used for mounting the new usb device using ecryptfs is as
follows. the password is stored (temporarily) in /root/usbpasswd.txt :
mount -t ecryptfs \
-o "rw,key=passphrase:passphrase_passwd_file=/root/usbpasswd.txt,\
ecryptfs_unlink_sigs,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,\
ecryptfs_passthrough=n,ecryptfs_enable_filename_crypto=y" \
/mnt/usb2/ /mnt/usb2/
Instead of mounting the freshly formatted /mnt/usb2 using password in
file, I am prompted for `Passphrase File` as follows:
Passphrase File: /root/usbpasswd.txt
Passphrase File: /mnt/usb/password.txt
Passphrase File: /root/usbpasswd.txt
Passphrase File: ^C
What could be wrong here?
Thanks and regards,
Raj
