Another Complete Shot In The Dark...

Idea 1:
What if we thought of the question as:

Why The (CombOfNatashaOtomoski) Has 21 teeth?

My reason to focus on CombOfNatashaOtomoski is that it's 21 chars.

Likewise, we can choose to interpret the question in 2 more ways:
Why The Combination "OfNatashaOtomoski" Has 21 Teeth?
Why The Combination Of "NatashaOtomoski" Has 21 Teeth?


Idea 2:

Letters like m, n, h can look like teeth. Depending on what you interpret to look as a tooth (e.g m looks like 2 teeth):

      1            2                3,4                                       5                      6,7                    8                                        9
W   h   y   T   h   e   C   o   m   b   O   f   N   a   t   a   s   h   a   O   t   o   m   o   s   k   i   H   a   s   2   1   T   e   e   t   h      

9 "teeth" in this sentence, or more or less depending on what you interpret as "teeth".    


Just trying to think super "out of the box"...
                    

Edit: Included more interpretations of the question

Exactly!...how the heck do we check? For the love of everything, OP, release a second hint..

https://en.wikipedia.org/wiki/Dental_notation

In following with my previous idea that the teeth reference is a literal one, I just discovered that Dentistry labels teeth from A-T, and 1-32.

Coincidentally, the phrase CombOfNatashaOtomoski does not contain letters outside of the range of A-T.

Might be useful..

[HCP]

whe you will find something how you check it on correct ? 

Exactly!...how the heck do we check?

It's fairly simple.

You convert your 8 word/32 char, CamelCase English phrase with no special symbols into a private key/address (ie. brain wallet)... if you get the address: 179sxfh6rw6bHSo5wVUhLP96k46QaEzVP then you go it correct. If you don't get that address, then you're wrong.

So I'm tired of trying this weekend.

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

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?

I’ll 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.

I get what you're saying, sure. But just because a key exists that turns one phrase into another doesn't make that key meaningful.
If it was a 3- or 5-character key, that could be more meaningful. But there will always be a 15-character key that turns one 15-character phrase into another 15-character phrase. So it's basically irrelevant.

[jajorda23]

Totally hear you, Cassius. Here's my method, though.


Here are the steps...basically...and of course I could be wrong but take it with a grain of salt.

1. We know Natasha Otomoski is equivalent to Satoshi Nakamoto. That's very obvious.

2. To obtain NATASHAOTOMOSKI=SATOSHINAKAMOTO we know how the letters have to be arranged. Its exactly what Watashi-Kokoto said (whether he's the OP or not doesn't matter).

3. So numbering 1-15, we get "5, 2, 3, 8, 13, 6, 15, 1, 4, 14, 7, 11, 10, 9, 12"

4. Now let's use an alphabet:

5. A=1, B=2, C=3 D=4, E=5, etc..

6. Now rearrange the alphabet using step 3:

7. "E   B   C   H   M   F   O   A   D   N   G   K   J   I   L"

8. This is the decryption key.

9. (8,2,3,9,1,6,11,4,14,13,12,15,5,10,7)⇔(5,2,3,8,13,6,15,1,4,14,7,11,10,9,12)-1



SUMMARY

What I'm saying is that we know the NATASHA --> SATOSHI is a permutation. So, why wouldn't the rest of the phrase be as well?  I could be totally in left-field, for sure. But this is my best assumption.

My issue with this is that while it's clearly an anagram, it doesn't have to be a permutation cipher. In fact, the odds of it being a permutation cipher actually seem pretty low - because the key has to be 15 characters long. Example:

SATOSHINAKAMOTO
CRAIGSWRIGHTBTC
A key exists that maps the first to the second... but that doesn't prove anything.

3- or 5-character keys would also work, but none exist that map Natasha... -> Satoshi. If there was one, this would dramatically increase the odds of being on the right track.

[Wendigo]

There are 35 characters (37 if we take the number 21 into consideration) so I am not sure how you could possibly derive the right 8 passwords through a permutation cipher.

This puzzle is truly mind boggler one and the prize is quite interesting I did not encounter any puzzle like this before you need to have a strong technical background in cryptography before you can answer this also tried with some combinations using the brainwallet for almost 3 hours but no luck. .btw I can see .txt at the end of the answer is not actually related to answer in my opinion its just a file extension from the filename.

Satohash seems like a commonly followed repository between them all on Github.

I mean, there are several possibilities here. It could be that OP expects us to input a 32 (i.e. 32 bytes = 256bit) char english worded answer, convert it to private key through some algorithm like the one in the link.

It could also be that OP is simply referring to an 8 word 32 char answer to be input into a brainwallet checker right away.

It could be that the answer to the question leads to a second clue that will contain the private key.

Who knows?
