The Big Rip

[czardas]

The Big Rip is the name given to a theory in physics where the expansion of the universe accelerates to the point where even atoms get ripped apart. The first signs of the big rip will be when stars start to disappear from the night sky.

Believe me you will be waiting around longer than the end of the universe if you try to randomly brute force even quite a short big rip encoded message. It works using the simplest possible method of all - namely the barrel lock. While most barrel locks are one dimensional, this one is three dimensional.
Is this an encryption program?

It was iintended as a coding exercise more than anything else. It fails as a universal encryption program because this version only works on multiline text documents written in AscII which contain the full delimiter string @CRLF. The text does not need to be arranged in a square. Anyone thinking of trying a 'meet in the middle attack' should look at what happens when you try to encode a message where all bits are set. It simply doesn't work. Is this a weakness? Well you decide.

There are no instructions and all the controls are hidden (I want you to try and figure it out). Just something to put off a would-be hacker who happens to find your lost portable storage device. It might buy you a bit of extra time to cancel your credit card pin.



Thanks to Guiness for help with the muliline password control. That's one unique feature you don't see every day.

Thanks for looking.

When I was 11 years old I set a challenge to my teacher. I created a sequence of numbers some of which were missing. To my amazement my teacher had filled in the missing numbers before hometime. I was gobsmacked! It was a good lesson, but I'm going to stick my neck out once more. I could end up eating humble pie, but we'll see.

The first person to provide the correct plain text and password to the encoded message in the previous post gets a financial reward. £50 (UK) is currently on offer and the challenge lasts until the end of 2012. I know it's not much, however if after midnight GMT on 31 Dec 2012 nobody has come up with the solution, I will consider renewing the challenge.

If a wrong but plausible solution is discovered, it may be necessary for me to reveal the real solution to resolve the matter, at which point the challenge will be withdrawn.

The password should be either a sequence of characters or an array of numbers. I know there are people out there who crave challenges like this. Crack the big rip challenge, if you can.

@ac1dm4n You never know, there's a lot of talent out there!

I hashed the file using sha1 method

Edited April 30, 2012 by ac1dm4n

@ac1dm4n You're not supposed to respond to this thread. Thanks for confirming the hash of the text file for me anyway. You will notice that the forum code boxes are formatting the cyphertext and corrupting the message, so what you have posted is no longer correct. This is why I decided to zip the file up and attach it to post No3.

Only joking about not responding BTW. Questions about the program will be answered. Questions about the plaintext to the challenge will be ignored.

Thanks to those who downloaded this.

Question

How long did it take you to figure out the controls?

Do you think they are obvious or not?

I have to keep reminding myself that no responce is a good sign.

hehehehe

[czardas]

The strange thing about this program is that it sometimes flickers either blue or red. I don't know why it does that (although it doesn't bother me too much), but why blue and red? Is it something to do with blue shift and red shift?

Anyone knows why it does that, please let me know (or any way to fix it).

Edited May 14, 2012 by czardas

I have a sneaky suspicion that the solution to my previous question was to use $WS_EX_COMPOSITED style for the GUI. Does it still flicker? (required resources are in the zip file - 1st post)

[Extract]
Conventional wisdom says the universe is
infinite. But it could be finite, merely giving
the illusion of infinity. This possibility has
plagued philosophers and  scientists since
the beginning of recorded history. But now
modern science is starting to drag this
abstract issue into the realm of the real,
the tangible and the observable.

How the universe got its spots looks at how
science is coming up sharp against the mind-
boggling idea that the universe may be finite.
Such a revelation would provide the ultimate
twist to the Copernican revolution, for we
would find out exactly where we are in the
cosmos. Its impact would be even more
radical than the discovery that the Earth is
round or that the Earth is expanding.
Through a decade of observation and
thought-experiment, we have started to
chart out the universe in which we live,
just as we have mapped the oceans and the
continents of our planet.

Now, in the dawn of the new millenium, details
of this grand cosmic map are coming into focus.
Through a kind of cosmic archaeolegy and
without leaving Earth, we can look at the
pattern of hot spots left over from the big
bang and begin to trace the ‘shape of space’.
Beautifully written in a colloquial style, How
the Universe Got its Spots explores our aspirations
to observe our universe and contemplates our
deep connection with it. While relating her own
personal and intellectual journey through
space abd time, the author gently takes in such
gravity-defying concepts as black holes, time-
warps, invisible ‘strings’ and chaotic flows.
It is a fantastic voyage, impressing on us the
extraordinary fact that we are progeny of this
universe and that our ability to understand it
is an inheritance.

[Extract]
In the last twenty years or so, a clear pattern has emerged in the world of chess—
the overall superiority and depth of the Russian chess masters. This book was prepared
originally in 1947 by Irving Chernev, one of our countries leading experts, in an effort
to point out the causes and factors contributing to this decisive supremacy of the
Soviet aces over American and other players.

Chernev has put together a remarkable anthology of games—chosen from among
thousands of top-flight matches involving Russian masters. Fully annotated and dia­
grammed, they provide a unique, analytical view of the emergence of Soviet domin­
ance, while illustrating the winning styles of about 40 prominent players. There are
over 50 modern, instructive games by such greats as Botvinnik, Keres, Boleslavsky,
Kotov, Ragizin, Tolush,and many others.

For this new edition, Chernev has included an additional section containing analysis
of six games played in recent years by Smyslov, Petrosian, Taland Bronstein. Inci­
dentally, all were virtually unknown when this book was first published—indicating
the continuing progress and development of Russian chess mastery.

Here are examples of the artistic endgame, the brilliant queen scarifice, the extended
combination (one splendid combination by Botvinnik is carried out successfully for
over twenty moves!), the imaginative attack, the beautiful trap, etc. in games which
help to make clear why the Russians have attained the top rank in international play.
These games offer a treasure-trove of ideas in chess strategy; a study of them will be
of inestimable value to chess players of every level.

Enlarged version of the work first published in 1947; 6 additional games. New preface
for this edition by the author. Total of 637 diagrams. viii + 215pp. 5 3/8 × 8.

Conclusion

The impression I get is that this system is very strong. I can only liken it to doing a massive Rubix cube blindfold: since a normal rubix cube has a known outcome. Considering that it took Google 30 years to crunch through all the possible solutions from all starting possitions of the rubix cube, I never much feared for my money. However encryption is not my expertise, so who knows?

With this project I learned something valuable about handling complicated algorithms, yet the overall concept is in reality very simple. I wouldn't go as far to say it is impossible to crack, just that it may take forever.

The original idea for this project started here:

I think I may make a weaker version of this (to increase speed and size limitations).

 

I did exactly that. There's no reason to have an encryption where you have to wait until the end of the universe to see if anyone can crack it. The following encryption should be far weaker than the previous. It's much faster and more flexible. The code still needs additional error checking.

CODE DELETED

;I just need to create a new GUI for it. This is my final attempt at working on such a project. Code will be removed to a new location shortly, so take a look at it now. I prefer it for its simplicity.

This is quite interesting.. how the heck does one come up with it?!

[czardas]

Joeit I'm glad you find it interesting. I found it a challenge to come up with a unique encryption. How strong it really is is difficult to say. If I try to do the maths for the time it takes for brute force attacks, the numbers get silly. I know how it works and I wouldn't have a clue how to unscramble the data without the correct password. This is not quite the final version, but very close.
