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?
