So I'm tired of trying this weekend.

Quote

NATASHAOTOMOSKI --> SATOSHINAKAMOTO

is a permutation cipher. I've known this for a while. Here's the key:

e b c h m f o a d n g k j i l

Here's what I can't figure out. If the remainder of the phrase is also a permutation cipher, how do we extend this key? It does NOT work for the entire phrase.

If we can figure out the key for the WHOLE phrase, that'll give us the full translation for whatever the ?.txt file might be.

Someone skilled in decoding might have some ideas. Let's keep this going

edit:

5   2   3   8   13   6   15   1   4   14   7   11   10   9   12
S   A   T   O   S   H   I   N   A   K   A   M   O   T   O

How can you be sure this is a permutation cipher? It's equally possible the 'key' is just the result of a random anagram, right?

Ill type a detailed response after breakfast. You can use this permutation cipher silver to check the key. Type natashaotomoski in the bottom box, the key where it says key, and hit decrypt.
