[Dvdrtools-users] Re: crypt ISO image -- can't encrypt images any more than you can compress

First off, an .iso is an image of a filesystem, ISO9660 or UDF specifically.

Secondly, if you crypt/compress the .iso, you can't burn it with cdrecord AFAIK.
 If I'm wrong, please correct me.

You'd be better off doing encryption on a per-file basis, then mastering the
image from that.

Correct.

So you're not talking about burning it to media, but just leaving it as a
"single file" on your hard drive?  If so, then you _can_ do such using the
loopback device.
