Encrypting any kind of data storage?

Hi

here's the situation: I need an EASY (or at least scriptable) way to
encrypt/decrypt every single "sector" on a given storage device (flash
drive, hard drive, floppy disk etc.pp.). Ideally that would be done
using a boot disk (boot CD, flash, floppy...). Any suggestions on how to
do that securely?

Also, does anyone know of any good research paper on recovering (or
prevention of recovery) of overwritten data on various kinds of storage
media, i.e. which one is safer? magnetic vs. optical vs. electronic?

Thanks
Jens

The loop device supports encryption; see the losetup(8) and mount(8)
manpages for details.

optical media is not a 'long term' storage solution ...

Nor are magnetic or electronic (solid state) storage particularly good
long-term solutions.

Magnetic tape is probably the best option, but it needs to be
adequately shielded against electromagnetic interference.

Unfortunately, the data density of punched tape is too low to be of
practical use nowadays.
