Clearly. it has to be a return to triple component vector displacement crypto for me - that means accepting the large plaintext to ciphertext expansion ration of that cryptology as de rigueur but essential. - AOB

That's the wrong lesson. Such a return won't help in the slightest.

Until you solve your key scheduling problem (which you never will
because you don't understand the problem and have no idea how to solve
it or even that a solution is necessary), a realistic use of *any* of
your cryptosystems (if there is such a thing as a realistic use) would
see Alice and Bob re-using the same key many times, giving Eve an easy
"in" to your cipher.

I think I could probably post a hundred CDX-4 ciphertexts, all encrypted
with the same key, without worrying unduly about any of their plaintexts
being revealed in less than about six months (and possibly a fair bit
longer).

But, thanks to the unique way you design cryptosystems, if you were to
post twenty-odd ciphertexts all encrypted with the same key (and if you
didn't cheat, and if by some miracle you were able to do so without
corrupting them), I'd be very surprised if the cipher held up for more
than a fortnight.

There is no substitute for learning.

We keep leading the horse to water, but he (AOB) continues to refuse to
drink.

And it is amazing that when no one bothers to break his crypto in
several days, he takes that as perfect proof of his assertion of
unbreakable. But when someone breaks one within two hours of posting,
he simply shrugs it off, has zero curiousity as to how (I'm very
curious how colin's breaking them) and trots off to make another
trivial change to his 84MB of Ada duplicated source code only to return
and try yet again.

He has already done so. There's none so blind as those who will not see.

Perhaps we suffer, in a sense, from the same problem. We keep hoping
against hope that he will learn *something*, despite vast swathes of
evidence to the contrary.

Well, I broke the superencryption on ShuttlePads so thoroughly that he
removed it. I then showed, often in nauseous detail, how to get
plaintext out of ShuttlePads, VeeCrypt, and DotCrypt - all of which were
completely unbreakable according to their author.

Colin seems to have taken up the reins now, which is fine by me. I
hereby announce my retirement from breaking AOB ciphers - at least until
such time as he fixes his key scheduling problem and learns about diffusion.

I'd be interested to hear your reasoning!

Also I'd quite like to know why Chris M. Thomasson suggested 'status'

The actual answer isn't particularly interesting. What *is* interesting
is the thought processes that go into people's attempts to find a
solution, because pattern-matching is intrinsic to cryptanalysis.

The sequence of first letters in the capitalized words indicated

realize the pattern required another lowercase 'stitching' word like
"of".

It was a shot in the dark, but sometimes that works.

Yes, there is a strong pattern of UPPER lower, so that would suggest a
six-letter *lower* case word; but there is no alphabetical sequence in
the lower case words.

It does. But this time it didn't. :-)

But you made headway. You spotted two patterns. One of them might be
significant. And there might be other patterns too (or, at least, a very
interesting fact about one of the sets of words).

We keep leading the horse to water, but he (AOB) continues to refuse to
drink.
And it is amazing that when no one bothers to break his crypto in
several days, he takes that as perfect proof of his assertion of
unbreakable.  But when someone breaks one within two hours of posting,
he simply shrugs it off, has zero curiousity as to how (I'm very
curious how colin's breaking them) and trots off to make another
trivial change to his 84MB of Ada duplicated source code only to return
and try yet again.

He has already done so. There's none so blind as those who will not see.
Perhaps we suffer, in a sense, from the same problem. We keep hoping
against hope that he will learn *something*, despite vast swathes of

Or perhaps more importantly, what's missing? Well, let's just look at
the six-letter words beginning "oa".

First, the *nix file: grep -ix "oa...." /usr/share/dict/words | fmt

Oahu's Oakley Oaxaca oafish oaring oath's oats's

As you can see, it cheats a bit, as it includes some hits that are using
punctuation instead of letters! Let's drop those, which leaves us with:

Oakley Oaxaca oafish oaring

Now from my dictionary: grep -x "oa...." bigdict.txt | fmt

oafdom oafish oakers oakier oaklet oakums oakweb oarage oarial oarier
oaring oarium oarlop oarman oasean oatbin oatear oaters oathay oathed
oaxaca

A good solid 21. Let's take away the hits from /u/s/d/w:

oafdom oakers oakier oaklet oakums oakweb oarage oarial oarier
oarium oarlop oarman oasean oatbin oatear oaters oathay oathed

Not perhaps the commonest of words, and I think the /u/s/d/w folks have
probably got the balance about right - they've included pretty much all
the words that pretty much most people pretty much need (99171 in my
case), presumably deciding that if anyone needs a more detailed list
they're perfectly capable of jolly well finding their own (431963 in my
case).

Just for the benefit of our studio audience, I can now confirm that
Colin's answer is 100% correct.

A puzzle without hints would have been better, though. Mostly I
undershoot this group (i.e. it is more resourceful and creative and
downright sneaky than I would have predicted), but occasionally I
overshoot. This time, it seems, I overshot.

Here's where I stand with this; the capitalised words are obviously placeholders
for other words. "Obviously" because of the A, B, C... pattern and the complete
superficial unrelatedness of them. The lowercase words have a structure that
looks like they want to be a sentence "Suppose A policeman OFFICIALLY talks
OF someone WHO is ...." or some such. Belgium could be (e.g) Flanders, which
may be in turn code for "philander(s|ing)".

I posted a hint else-thread, in ROT-11.

Here's another hint, though, in the clear. The word list is clearly made
up of pairs (upper and lower case), and the alphabetisation of the upper
case words suggests strongly that order matters.

Does that help at all? I recommend that you chase down that other hint,
though.

expansion ration of that cryptology as de rigueur but essential. -
AOB

That's the wrong lesson. Such a return won't help in the slightest.
Until you solve your key scheduling problem (which you never will
because you don't understand the problem and have no idea how to
solve it or even that a solution is necessary), a realistic use of
*any* of your cryptosystems (if there is such a thing as a realistic
use) would see Alice and Bob re-using the same key many times, giving
Eve an easy "in" to your cipher.

It is quite sad how unwilling he is to listen and/or learn anything.

Post by Richard Heathfield
I think I could probably post a hundred CDX-4 ciphertexts, all
encrypted with the same key, without worrying unduly about any of
their plaintexts being revealed in less than about six months (and
possibly a fair bit longer).
But, thanks to the unique way you design cryptosystems, if you were
to post twenty-odd ciphertexts all encrypted with the same key (and
if you didn't cheat, and if by some miracle you were able to do so
without corrupting them), I'd be very surprised if the cipher held up
for more than a fortnight.
There is no substitute for learning.

We keep leading the horse to water, but he (AOB) continues to refuse to
drink.

Unfortunately, "apparently" so. Think if Austin is hyper smart, and just
playing around, like a real Eve... Perhaps, he has us all tricked at a
certain level! Btw, thank you for your patience with all our
correspondence for I have learned a heck of a lot here, in this group:
Thank you all.

Btw, Austin:

And it is amazing that when no one bothers to break his crypto in
several days, he takes that as perfect proof of his assertion of
unbreakable. But when someone breaks one within two hours of posting,
he simply shrugs it off, has zero curiousity as to how (I'm very
curious how colin's breaking them) and trots off to make another
trivial change to his 84MB of Ada duplicated source code only to return
and try yet again.

Hi Chris,

Re hexdump :-

My personal hypothesis is that ASCII is physically so low down (positionally) on the Unicode standard format that when any decimal number that represents an ASCII character such as in my AOB cipher recently is converted to Hex the chances are high that the ASCII character in question is represented by the first two digits of the converted number.

The upshot of this then is a secondary fallout string of character possibilities (emanating from studying the first two hex digits conversion) that will have a very pertinent probability that Eve can work on with fairly high expectations of success. Ordinary cryptanalysis of this new string is then possible.

The antidote in my opinion would be to for Alice to convert the English language plaintext in hand into some other language that is a lot further along (highre up)the Unicode list - even a JCK language might be needed if necessary.

The operative word here is this "The number under scrutiny MUST represent, by direct mapping of the character that is being attempted to retrieve by a hexdump (in normal decryption by Bob say)and not just be related to it in some remote tenuous correlation like some weak arithmetical functional way ".

*Using other number bases would not be as good as hexadecimal In my view.

Le Meas,

ASCII is a seven-bit code. On modern PCs, bytes are eight bits. So an
ASCII character always fits in a byte. The chances aren't just high. The
chances are 100%.

(Unicode characters take several bytes. A hex dump would deal with these
one at a time.)

You *cannot* be this stupid. The reason a hex dump was used was simple:
Colin (or whoever it was) had a decrypt that was correct except for the
first handful of bytes (nine, I think?), which didn't give him printable
characters. The hex dump enabled him to inspect those byte values
directly, that's all.

In your strange, twisted world? Perhaps. But real cryptosystems don't
care what kind of file Alice encrypts. They can deal with all of them.
And they don't give a stuff about hex dumps, because hex dumps can only
display information you already have. If Eve has the plaintext, it's a
bit pointless to be worrying about whether or not she hex-dumps it.

Post by a***@hotmail.com

Hex dumps don't attempt to retrieve characters. They translate
characters. So if you have a file like this:

Hi Bob II, this is Alice.

a hex-dump looks like this:

48 69 20 42 6f 62 20 49 49 2c 20 74 68 69 73 20 |Hi Bob II, this |
69 73 20 41 6c 69 63 65 2e 0a |is Alice..|

Note that the first value, hex-48, is 4 * 16 + 8 = 72. ASCII 72 is H,
the first letter of the message. And so on.

That isn't because the hex-dump magically guessed the contents of the
file. It's because the hex-dump was told the name of the file, and then
it pulled out the data from the given file, one byte at a time.

That's all a hex-dump does, okay?

[MM]

My personal hypothesis ...

Why do you need a hypothesis? Unicode is *WELL* documented, and the
full facts are available.

... is that ASCII is physically so low down (positionally) on the Unicode
standard format ...

The top actually. The first 128 bytes, from 00 to 7F (or equivalently 0 to 127
in decimal).

... that when any decimal number that represents an ASCII character such
as in my AOB cipher recently is converted to Hex the chances are high that
the ASCII character in question is represented by the first two digits of the
converted number.

This is so mangled as to be nearly incomprehensible. In code points, Unicode
is a set of numbers in the range 0 ... 10FFFF hexadecimal. Generally speaking
you want the *LAST* two characters of the number, that is the rightmost
two, with zeroes padding the left if necessary.

The upshot of this then is a secondary fallout string of character possibilities
(emanating from studying the first two hex digits conversion) that will have a
very pertinent probability that Eve can work on with fairly high expectations
of success. Ordinary cryptanalysis of this new string is then possible.

Nonsense.

The antidote in my opinion would be to for Alice to convert the English
language plaintext in hand into some other language that is a lot further
along (highre up)the Unicode list - even a JCK language might be needed
if necessary.

Rubbish. There should be no need to change the plaintext, ever.

The operative word here is this "The number under scrutiny MUST
represent, by direct mapping of the character that is being attempted
to retrieve by a hexdump (in normal decryption by Bob say)and not
just be related to it in some remote tenuous correlation like some weak
arithmetical functional way ".

More nonsense.

Get rid of the word "hexdump" from your repertoire. You clearly have no
idea of its purpose.

*Using other number bases would not be as good as hexadecimal In my view.

Number base is irrelevant, as is your view.

Why? Bases larger than 16 can be more "compact" wrt storing larger
numbers. For instance:

9876543210 in base 10 can be represented in hex as:

24cb016ea

Well, it can also be represented in base 30 as:

dgd7qr0

Look, 2 symbols shorter than base 16! ;^)

Btw, you should look into extended ascii because it can hold the range
of an entire byte: (0...255) in base 10, or (00...FF) in base 16.

Hi,
Point taken but going outside of ASCII has no future even if the non-standard data appears to have useful crypto attributes. It can only be given non-negotiable, non-standard *curio value at this juncture.

The US government has set the bounds of the writable subset of ASCII and I am bound to observe this fact. Also, going outside of ASCII as a convenience to cryptology is not necessary in my current cryptography and I don't think I will ever do that anyway on principle - that is a perversion of the system that we are all signed up to so to speak. It is not becoming to cryptology to make exceptions. The US government got in first with the advent of computing in about 1963 and they can call the shots today - I don't think anybody disagrees with this.

Communication attempts re submissions of prospective ciphers with the NSA for instance will always draw the retort "Unsolicited data that is non-standard" - I haven't tried writing to them ever but I do know that is what happens when one does.

In passing, I am becoming more and more convinced that it is becoming sine qua non in the crypto establishment that scalar data has no future as an obfuscating tool in cryptography whatever and it can be written off as a non-starter.

The exceptions of course being AES that depends on the diffusion of binary digits that makes it irreversible in cryptanalysis and RSA that depends entirely on computer power. It may eventually become ubiquitous to cryptographers that scalar data and the associated methods that go with it are categorically prohibitive for the reasons that any cipher that uses it will be automatically prone to well known off-the-shelf cryptanalysis.

He's previously argued that his ciphers are easier to apply than things
like RSA since RSA requires graduate mathematicians to operate. (He had
no idea how a computer could perform multiprecision arithmetic and so
presumably had a rather Dickensian mental image of how it was
implemented, with lots of clerks performing paper calculations.)

He's also argued that GPS might be used to factor integers to break RSA.
And he's also argued that public key cryptography would entirely disappear.

So sure, there's some understanding but it seems very shallow (and
rather weak), and I don't see any sign it's changed in any way.

(He does seem to have abandoned Unicode in favour of ASCII for some
reason. Once upon a time he was all in on Unicode (and Unicode was one
of the main (confused) reasons he chose Ada), with ASCII just being a
bit easier to demonstrate. Might just be that generating mutual shared
databases is even more annoying to do for Unicode.)

Another opportunity to demonstrate decryption by " Hex Dump " from a
distance. or indeed by any cryptanalysis. Nothing by way of decryption
came out of the last test sample.

Shortly after Darnay arrives in Paris.....

Just over two hours, *if* you saw the post as soon as it was made.
(Unlikely.) So probably a lot quicker.

Now, let's get this into some perspective.

You were faced with an unbreakable cryptosystem - and we know it's
unbreakable because AOB said so (just like he says all his cryptosystems
are unbreakable, usually not long before they get broken). You cracked a
ciphertext in probably rather less than two hours, even though AOB said
this is utterly impossible.

And his reaction? "Fair cop."

Not: "man, you must be the greatest cryppie ever, how the hell did you
do it, what am I doing wrong, how can I learn from you?"

Nope. Just "fair cop".

And in a couple of weeks he'll be back with a piddling little change
that he thinks makes the cipher unbreakable again, and he'll laugh scorn
in our faces for pointing out stuff he ought to be learning, and he'll
wave challenges around and celebrate for every day that passes without
anyone bothering to pick the challenge up - and then, eventually,
someone will get fed up with it and post the plaintext... and round and
round we go.

I wouldn't mind so much if he showed that he could *learn*.

Another opportunity to demonstrate decryption by " Hex Dump " from a
distance...

Hexadecimal file dumping is not a "from a distance" method.

It is used to display data that you already have in a way that
unambiguously shows the values of all bytes, not just the
printable ASCII ones.

I was demonstrating software engineering to children not so long
ago, and even they knew this.

Another opportunity to demonstrate decryption by " Hex Dump " from a distance. or indeed by any cryptanalysis. Nothing by way of decryption came out of the last test sample.
