I am trying to encrypt individual sessions on a CD-ROM using aespipe with the
intention of being able to recover them using the kernel's loop device.
The algorithm I would like to use is something like:
1. Get the old session parameters
cdrecord -msinfo dev=0,0,0
2. Create a new session and encrypt it on the fly
mkisofs -C params -M /dev/cdrw -o -r /backupdir | aespipe > crypt.iso
3. Burn the encrypted image:
cdrecrod -multi -pad dev=0,0,0 crypt.iso
This much seems to work ok (in that the actual command succeeds). To recover the data, I would like to do something like:
mount -o encryption=aes,loop=/dev/loop0,session=C /dev/cdrw /mnt/data
However, this doesn't work: mount doesn't believe that the filessytem is
iso9660. I suspect that there is a fundamental flaw in the method I am trying
to use; can anyone comment if this is so, or have I missed something simple?
Many thanks for any comments or advice,
Jim Sweet
