Game: Crack the code

Heres a new game for us to try. One doper posts a sentence or paragraph that is in a certain code-thing, like cryptograms. Everyone else tries to figure out what the sentence says, then they post it and as much of the code as they know. They then post a new sentence/paragraph with a different code.

Example:

Jqpe pe tnxf g jyd. Lt xtj my gngfcyl.

means

This is only a test. Do not be alarmed
when the code is:

a-g
b-m
c-z
d-l
e-y
f-k
g-i
h-q
i-p
j-b
k-v
l-n
m-c
n-x
o-t
p-a
q-h
r-f
s-e
t-j
u-w
v-s
w-o
x-u
y-f
z-r
So, here’s the first one:

W oa jsfm jsfm jsfm pcfsr. Gc pcfsr hvoh W oa rcwbu hvwg.

I am very very bored. So bored that I am doing this.

Heres mine:

moyn yn d rym mxygoywx.

No takers?

Here is a hint if you are really stuck:

m=t o=h y=i n=s

Did you goof that last word? I can’t find any words that fit TIHI**

Correct, skidoo.

and let me just add:

DOH!

and

:smack:

It should have been this:

moyn yn d rym mxygpywx

Solution:

this is a bit trickier

Someone please post another code, I feel a bit silly now… :rolleyes:

I could toss up a perl coding script so that you could encode your own inputs. I think that’s about the only way to solve this.

Wikkit, there are tons of similar things at various webpages.

Except that I didn’t use a monoalphabetic substitution cipher. Similar, perhaps, but the same? Prove it. :slight_smile:

I figure this is a Vignerie Square. I can’t program and am not so motivated but am I on the right track?

BTW, if anyone is interested, The Code Book, by Simon Singh is a riveting, fascinating look at codemaking and codebreaking through the ages.

No, not a standard Vignere Square, but related to it. I’d never heard of it until now, it’s pretty interesting; especially that Babbage cracked it and never told anyone.

Actually, the Vigenere cipher is quite easy to crack if you know what you’re doing. However, Wikkit’s code is far too short for me to attack it using one of two standard techniques. Hmmm…interesting…

Alternating Bi-alphabetic?

10 alphabets, so it’s not square, but they’re all used in a non-linear non-random way. I can provide a larger sample if desired.
