Cute. Is it available?
$39 + tax in Fry's.
I don't mean the disk - there are lots of those.
I mean your software.
Also, can your tool use floppies instead of USB keys?

How do you prevent other applications from reading the file off your
USB disk, either while your application is using it or some other time?
That's

OTP is also good when:

Its certainly usable provided key distribution isn't an issue - if it is
also worth the trouble and expense is another matter.

Pretty much, yes. at least one real world OTP system assumes you will
be using three CDRW disks; the three are xored (as you say) together,

Naive question here, but what if you made multiple one time pads (XORing

hi,
An extract frm this months cryptogram goes as below.
On the other hand, if you ever find a product that
actually uses a one-time pad, it is almost certainly
unusable and/or insecure.
So, let me summarize. One-time pads are useless

OTPs won't help a bit for that problem.
