This is just coded english, it is no more a seperate language than the ASCII encoding itself is a seperate language.

And it's not half as evil as talking in Finnish

As for them writing a program to crack it... that would be quite difficult, and I could just change the encryption scheme.

Does anyone want to guess the encryption scheme, or should I just post it?

Drogue · May 25, 2003, 18:53

I'd go for posting, I can't see us guessing it straight off, although I did have a look at the program the other day...

Cedayon · May 25, 2003, 21:52

k, the encryption:
x = random number from 1 to 31
output binary 5 bit binary encoding of x
output x random bits

for each character a in the input string:
__b = binary encoding of a
__y = random number from 0 to 1
__output y
__if (y == 0)
____output flip1(b)
__if (y == 1)
____output flip2(b)

output x random bits

output = flipS(output)

done

flip1, given an 8 character string, outputs it in the order: 2,1,4,3,6,5,8,7
flip2, given an 8 character string, outputs it in the order: 3,4,1,2,7,8,5,6
flipS, given an input string, outputs it in reverse order.

Decryption is obvious, just very tedious, which is why we're letting the computer do it

I bow to your superior encryption skills.

With you on our side, not even Datajack Roze herself can hack us!

Cedayon · May 26, 2003, 00:45

I'm taking Web Programming right now (May term), so the actual program follows from what I've been studying, and the actual encryption stuff is nothing special... I could have made it much more complicated, actually (with, say, a 2-3 bit prefix to each character, choosing between 4 or 8 different kinds of flipping, or 8-16 if I did something different with characters at places that are multiples of the random key number or have the same evenness/oddness of the key), but I figured this would be sufficient... I'll save the other tricks for the possibility that this code is compromised.

It was a decent amount of work, though, and I'm glad it's helpful and appreciated

I wonder how hard the other factions will try to crack it... it's certainly possible (some of them seem quite intelligent), but it would be a lot of time investment, which is time investment not devoted to strategizing and such... and I would just change the code to something much more painful

I have found I problem. I translated:

Dammit, speak in new code you lot

Nice one Cedayon

Maniac: Jamski picked up on what Googlie said about it being the wrong day and went with the days of the week one. It only works on or 2 days a week, with out old code.

Corellion: What did you write in? I can't get it to work.

What code is Honghu writing in, tried deleting letters, doesn't work.

What's going wrong Cedayon?

However it does not translate back

Drogue · May 26, 2003, 17:20

DP sorry

Drogue · May 26, 2003, 17:29

Have worked it out. You cannot write more than one paragraph in the same translation. They must be translated, and re-translated paragraph by paragraph.

Drogue · May 26, 2003, 20:12

Also, how about we put a few just jumbled ones in there, saying nothing. Whenever you feel like it. Then they will think it's changed again, even if they get it. We can fool them so easily

Corellion · May 26, 2003, 20:43

What does everyone think of the Hive's new code? Actual unoriginal binary-related, or mindless jibberish in an attempt to get us to decipher it? We should have a poll on this.

My vote goes for gibberish, they're trying to goad us into a competition.

Drogue · May 26, 2003, 21:05

Either gibberish or adding gibberish somewhere into it. Zero's post certainly contains some gibberish, as theer are many 010101 throughout the middle of it, which are obviously added. I don't think it matters, will take a lot to crack, for something virtually worthless, as they won't put anything too important there.

Cedayon · May 26, 2003, 21:32

Oh, sorry, I thought I mentioned that you can't have line breaks in the to-be-translated string, or it pukes horribly

It's not much of a loss, because it can only take so large an input too, before it just gives up or something.

It's not perfect, just give it small inputs and it will perform acceptably (there's still that odd thing where it puts a '*' after every ')' when decoding).

As for Honghu's code... *shrug* I'm not gonna try to crack it, I just plug it into my decryptors to see if they broke the codes. We, the cyborg faction, have an RP justification for writing in binary... the Hive doesn't, they may as well write in Navaho or something if they want a code

Drogue · May 26, 2003, 21:43

That's a point I was trying to make to Jamski.

Corellion · May 26, 2003, 22:09

Indeed

Drogue · May 26, 2003, 22:25

Having spoken to Jam, they are trying very hard to crack it. We must be wary. He said their's was not too hard, but did not involve deletion (although it is not a multiple of 8, but of 4).

Cedayon · May 26, 2003, 23:08

If you want I can make a 3rd version of the encryptor that uses an even-more-disgustingly-mangling code, so even if they do break this one (which I don't see happening) it won't matter much.

Drogue · May 27, 2003, 09:08

I don't think that's necessary. It will take them a while, and we hardly discuss anything too sensitive. However, they have read all our old messages, since they solved that code.
