New crypto challenge!

Here's a new crypto challenge!

This one is actually an encoded message in plain English. See if you can decipher it!

TF IZ TLE I
FIZL ITI ELEZ JTZL E ZET
FI ETF Z
ZT YT EL V E M TEZ FL VI


Tip: it's not really mathematical...

Have fun! ;)

Ammo

i used a decrypter, and it couldnt find anything,.

illv //

ok, in a 20 questions style id be asking the following (assumin i get yes to my answers):

is it character substitution?
dose the character standard change with every letter?

ok thats only 2 outta 20 but those are my thought on it. i am thinking that its character substitution cause its just characters, but then that it changes characters cause thers 3 seperate 1 character groups in it and, assuming that it is in english, theres only 3 one character words in the dictionary, I, A, and j (tho ill be damned if i have ever see j used as a word before)

these are great, i got a college interview tomorrow and need to wake up in 7 hours and im spending time cracking sweet nothings, i love this place, there should be more challenges, there REALLY fun

I like the idea of the "crypto challenge"

But ummm... maybe a hint would help?

Is it like a cryptoquip?, or is it like encrypted with a variation of ROT-39?

Ok, tip time:
1- It's not really an encryption "alogrithm"... It's rather home made (think outside the box! ;)
2- It's "based" on an old binary encoding standard
3- Encrypting and decrypting in this way is a two step process.

Next tip I'll give you an a cleartext and it's ciphertext example pair!

Ammo

Ok, I sense this could get old fast if I don't post more clues...
Here's an example of a cleartext / ciphertext pair:

Cleartext: "Just an example"

Ciphertext:
IZTE VT YI F
JE ZL
I EUZ JF TF IEFL JTV L


This might give you a better starting point...

Ammo

Ok other tip..
Think more steganography...
Also, the text font does have some importance... AO's font might not be the best for this, but it is still decipherable...

Two step encryption process goes like this:
1- Encode in an old binary format
2- Obfuscate in a steganographic style
(Reverse to decode)

Ammo

PS: Next tip I'll try to post a little win32 prog (written in C++ MFC) that encodes/decodes..
It'll give away the cleartext of the challenge but you'll still have to explain how it works..

All right... the "old binary code" is morse code...
Can anyone see it now?

Ammo

I can see the correlations, but have not had the time to look at it anymore than being able to recognize it. Not that it helps... LOL

S...O....S...N...E...E...D...A...N...O...T...H...E...R...H...I...N...T.

Lol Negative ;)

Look for the morse in the shape of the letters...

Ammo

aaaargh! It's driving me mad!..........(sort of)

OK, I think I got it.

"Make Crypto Not Munitions"

Every letter with a dash in it (E, T, F, Z) gets a -

Every letter you would have to dot (I, J) gets a .

Every letter with a v (M, V, Y) gets a ..

Nice work DarkGuardian!!! Looks like you got it.

Ding ding ding!!! DarkGuardian scores! ;)

Little precision on DarkGuaridan answer: only look at the top of the letters for the morse...

Gotta admit it's an intersting obfuscation scheme!

Ammo

I didn't take long, once I used the example. The only tricky part was the M, V, and Y. After that, wasn't too bad.

But I wouldn't have gotten it if it weren't for the hint for morse code.

And you're right -- an interesting scheme.

ok still horribly stuck on this </ignorant>

so the first step is to run the initial code through a morse code convertor(since i dont know morse code)?
reverse the morse code?
then convert it back to english?

Fist step is to take only the top pixels of the letters and put that into morse:
eg: TF IZ TLE I => -- .- -.- . (top bar of the T, F, Z, E become "-" and top point of the I, L become "."

Second step is to run it through a morse translator, which will give the cleartext.

Ammo

ah yeah all good :( i actually didn't notice here was second page with hows its done
