But I'm really looking for a transparent solution, most importantly because I want to use
it with DVD-R - and don't wanna copy the whole image first...
I just tried the following (without success):
dd if=/dev/urandom of=cd1.img bs=1k count=65536
losetup -e aes -k 256 /dev/loop1 cd1.img
mkisofs -o /dev/loop1 -R -J photo-album/rawmart
losetup -d /dev/loop1
cdrecord dev=0,0,0 cd1.img
mount /cryptcd [with /etc/fstab entry: /dev/cdrom /cryptcd iso9660 loop=/dev/loop1,encryption=aes]
It seems, the whole CD is broken, because "cat /dev/cdrom" gives an I/O error.
Any tips??

Do I do this with mkisofs ... | aespipe -k256 ... | cdwrite - mount /dev/cdrom -o loop -e aes256 /cdromi just piped my iso image through gpg, while this doesn't allow you transparnet filesystem encryption it will always survive things like blocksize changes in the kernel(which happened in between 2.2 and 2.4). then you just dd the iso to the drive and decrypt it locally.
