Re: FileCopy overwrites the existing file

You've lived in USSR for too long...

Actually, I've been living in EU for the last 15 years....

You're letting the govt screw you too easily.

If you don't mind, could you please disclose your current location -
maybe, there is some
free place that I am just unaware of?

Windows CryptoAPI provides all first-class encryption algorithms, which
really "cannot be broken by agencies on a matter of minutes". The "agencies"
would really LOVE to do that, but don't have such luck

If you think so...... well, then keep on thinking this way - I don't
mind it at all

It's not 1980s-90s.

This is true.....

When it comes to civil liberties, quite a lot has changed in the
Western world since
11/09/2001....

And if you don't trust MS implementation, you can always find open source
code, which will really works the same way.

David,

Certainly, bitlocker is a good idea in itself, at least
*THEORETICALLY*. However, let's get real....

Taking into account current trends, i.e governments attempting to
control every single aspect of people's life, do you really think MSFT
would be allowed to offer "common users" any encryption scheme that
cannot be broken by agencies on a matter of minutes?????

Therefore, if you are really concerned about your privacy, you may
need something "custom"....

I would suggest you read up on bitlocker that comes with Vista. If you
use
a TPM you don't care about the algorithm because it is documented and has
been vetted to ensure it is 'secure' or some definition thereof. There
were
a couple of posts today about how the BIOS and TPM protect the
PIN/password
by making it slow enough that testing a 4 digit pin would take a year to
test all/half of the possible values.

I would like to see some posts from RSA and Counterpaine about bitlocker.

Grzegorz,

Actually, after a thought - it is a brilliant idea and it could be done
quite effectively.


I said it, then thought about what I said...... and at this point I
realized that I had eventually come up with the idea of a commercial
product, which I was stupid enough to give away to the entire world
right on the spot.....

To be honest, I've been thinking about my own product for around 2
years without any successes (developing something that already exists
is not a great fun,don't you think), and have accidentally arrived at
something of interest. One of the guys I used to work together with
does something similar, but he does it for Linux - he writes his own
(stripped-down) Linux distribution that comes on USB keychain.

However, the problem still remains - once we are speaking about the
general-purpose commercial product, again, we get into the trouble with
hiding algorithm details (after all, who holds the attacker back from
disassembling the part that comes on the CD once he can easily purchase
it???)

In fact, I have some thoughts on the subject (one can design a
not-so-pseudo random
sequence that is defined solely by the N-bit key that the user has to
define himself, so that after N iterations the same seed may produce
2^N paths that depend solely on the key, and decoding some certain
value(s) does not help you with decoding the whole key)

Anton,

Actually, after a thought - it is a brilliant idea and it could be done
quite effectively. The drive would have all hardware architecture
required for encrypting/decrypting and all the non-critical software.
Now, the critical parts of an algorithm would be provided with the key
and loaded temporarily to the hardware each time you boot your machine
or connect encrypted drive. Such drive would be dedicated mini-computer.
