I agree - this and many other probelms with this legislation were pointed
out during its passage through Parliament but the UK government would not
listen.

If my memory serves, Crypto++ comes with a Makefile. Opening this with VC++ creates a
project and can successfully build the library. Do a MSDN search on "makefile" and
dealing with projects
with makefiles and you should be almost there.

He's likely sending several posts via indepdendent chains of anonymous remailers,
on the assumption that at least one of the chains will fail. Which, sadly, is an
all too fair assumption.

Because it already *has* its fair share of Usenet kooks. If we get any
more, we'll be over quota and get complaints from Immigration.

It is only spurious if the watermark generating method is kept secret right?
The contest is set up with nothing but content and no method published right?
Why should anyone be interested in this exercise since it simply restates a
known.
Steganography can be relatively secure if the underlying method is kept secret.
If it fails this test, it was pretty dumb.
WHEN the method is leaked, it will fall.
Am I missing something here?

Does anybody now of a website with "Frequency Anaylysis" tables for most of

And does anybody know of an application that can do the Frequency analysis

Quite the contrary, They have transformed someone who would
not pirate (because they already bought & posess a legal copy)
into someone who might pirate if they have a crash. Do you see
how nuts this is? How long do you need to retrain a non-pirate
before he becomes an avid pirate?
It's like drug traffic. Do you try to limit supply or demand?

Right, thank you. Because, of course, DeCSS can be considered a means of
"circumventing CSS."
I like the idea of using a legitimate player as a decryption oracle,
though. :)

Hi
I am looking for info as to what is the best, or proper university to enroll

Any help on this will be highly appreciated.

As any modern textbook on cryptology should explain,
an S-box (introduced to the public as part of the
Data Encryption Standard) performs a substitution;
it has an m-bit input and an n-bit output (for DES,
m=6 and n=4). In DES, such substitutions alternate
with permutations, to thoroughly diffuse information
as it percolates through the system. In software,
an S-box is usually built as a look-up table. For
more information, read a description of DES.

Subject: wince encryption algorithm
This is the secret Ace (and WinAce) encryption algorithm. It is a
combination of a Blowfish derivation and a SHA-1 derivation and it
uses Cipher Block Chaining. I called it AceFish therefore...
This code will only work on machines with Intel byte order! It
shouldnt be too difficult to adapt it for Motorola byte order,
anyway.
==== begin AceFish.h ================================================
ifndef __ACEFISH_H__
define __ACEFISH_H__
typedef unsigned long u32
class AceFish
u32 _p18
u32 _s4256
u32 _cbc0, _cbc1 // for cipher block chaining
static void hash(const char str, u32 hash5)
void encrypt(u32 res_l, u32 res_r, u32 in_l, u32 in_r)
void decrypt(u32 res_l, u32 res_r, u32 in_l, u32 in_r)
public:
AceFish(const char password)
void encrypt(void buffer, size_t bytes) // (bytes 8) == 0!!
void decrypt(void buffer, size_t bytes) // (bytes 8) == 0!!
void resetCBC()
_cbc0 = _cbc1 = 0
endif
