I've made a cipher.  This is not a cipher I would use for encrypting my bank credentials, but it should be interesting to see if you guys can crack it!

The ciphertext you're trying to break is this:

Old ciphertext, use the one on page 2.

Code: (Ciphertext) [Select]

KI"Gx=P#FG4"$5@t|sAo1*EVE>!HzpY$[U$#BF*@*_)=X-4=V_Q^<.h?H4G`%JtpEnmNb*,=g"v2TxKyss+9Fc`2pofMwcMhmV5jHw6'LIHdxoU6]?siZSU|LWXJ9_#p=(@3y"aFS[bV|nc)Fh.CY\Z&$pxi/+DL/3f067'bm?/%T&rPKtfU_|j7O()8w#+6{(nq0d&y;Qb!q;CW.{3@[LEHi&c8qh<`&te$@`/.;,M[ovm;@%d%SE

If you want to know the ciphertext for a chosen plaintext, post it in [code][/code] or [tt][/tt] tags and I'll reply with the ciphertext!

EDIT: Restored all the old ciphertexts, and put the V2 ones on page 2.  Ignore all the ciphertexts on page 1.

each seperate line is a seperate plaintext (why do you say cypher???)

I say cypher because I'm weird that way!  So there.

[Ipquarx]

The characters it can output are this: (Go ahead and encrypt this too... i guess)

Code: [Select]

!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~

(The newline at the end is no mistake)

And:

Code: [Select]

This time with each seperate plaintext in a seperate code block (includes newlines)

16 newlines. in case that doesn't come across right.

16 newlines. in case that doesn't come across right.

Code: [Select]

All trailing newlines are removed before the cipher is applied.

[Ipquarx]

>:(
well okay then mr technicalities
"aaaa" then 4 newlines then "aaaa"
"aaaa" then 8 newlines then "aaaa"
"aaaa" then 16 newlines then "aaaa"

My top-model deciphering skills tell me that Xalos' Cypher is bald showing us the most used letter of the alphabet. Case closed!

My top-model deciphering skills tell me that Xalos' Cypher is bald showing us the most used letter of the alphabet. Case closed!

So, all of them are equally-used?  That seems... improbable!  :)

[Pastrey Crust]

The new lines are increasing exponentially after each "aaaa", Ippy. That has to have something to do.

[Foxscotch]

all of these characters:

!"#$%&'()*+,-./0123456789:;<=>?@ ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~

individually, pls. I'm sure that would be tedious, but it should be easy to get the result for each one with a quick python program or something
also note that this is not exactly the same as ipquarx's previous one, it has a space before the first alphabet

Characters encrypted, in the same order

I can see patterns. I don't know what they are. But I see them.

[Foxscotch]

I can see patterns. I don't know what they are. But I see them.

the whole reason I asked for that was because in this post

Each ciphertext on a seperate line:

I noticed that "a" and "b" were remarkably similar
I have no clue what the patterns are either :(((

something really weird is that half the results seem to indicate that the number of characters in the ciphered text will always be multiples of four, but some also indicate otherwise. I'm sure that means something

also I numbered each character in that set, for my own use, and I guess I might as well paste it here too

(but now the space is at the front, rather than at 33. to correspond better to ASCII values. so if you're comparing it to the ciphered list you need to move the stuff at line 33 to line 1)
and uhhhhhhhhhhh xalos can you cipher a space and a ~ individually again? they seem to be the same when ciphered, judging by the list you posted. which doesn't sound right
