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.

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.

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.

blockladder / watashi-kokoto GitHub connection

Looking at blockladder's "project pr" forks, there is a user called bakujo. Not much by itself, but they are following one and only person: our watashikokoto.
blockladder and watashi are perhaps close friends.

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

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?

Forget using the code in the repository. There's no .cpp file (which I am not skilled enough to compose) so gcc won't compile it--the header file contains undefined references.

I was thinking.. 8 words 32 char....
an average of 4 letter per word....
it reminds me of the BIP39 wordlist... where all words have 4 significant letters (some only 3)

Maybe the question refers to that list somehow...?
there are 8 words in the question (not counting "?", "21", ".txt" )

I'm trying some COMB-inations.. so far nothing ...

To further the connection between Blockladder and watashi-kokoto:






They both have yahoo.co.jp addresses if that means anything to you. Blockladders PGP sig on github reveals his email.

Maybe they're both japanese?  Grin Grin Grin

The answer might not be part of the BIP39 wordlist at all. If OP just created a custom sentence in Brainwallet to fit the puzzle, it would invalidate bruteforcing with the BIP39 list.

In general, so, there is some kind of healthy logic! all that is connected with this riddle. a ton of information. which I read and rechecked in 2 weeks! on different topics! It is not even clear how a private key is obtained. and each of the probable answers has to be transferred through different systems and thus you get a different key, respectively !!! Not very informative (Given) this question! Abstract! 8 words 32 characters without special ... the digit is not a special character but it is not specified that it can be used! Generally from where do I know that this is not just the author’s backup wallet, from where he will withdraw this amount on a rainy day. Does a private key have any relation to the task at all? )))) Grin Grin Grin Grin Grin Grin Grin Huh

After looking at watashi's post they do seem like the same person. her post before this thread was about reversing something multiple ways until they all reach the same point. maybe its related to that


and the 2nd post to this thread shows a possible way to decrypt a piece of it.  so maybe you need to follow the steps done to decrypt that for the entire message.


Also on the first page she provides a solution on how to get the key.


i'm not a 100% sure they're the same person but assuming it is you would have alot of information to go on.

So...

You know how Watashi linked into a github repo by movedon2otherthings that included code for a tool called Satohash?

Yeah...the code didn't work.

BUT I FIXED IT!

There were absolutely no declarations in the header file to match the definitions.

https://github.com/jajorda2/satohash

You just need to compile in terminal:

Code:
gcc satohash.c hash.h -o run

You can then follow the example instructions in the readme.md.

Code:
./run
to execute whatever you're trying to do.



DISCLAIMER

I do not know if this has anything to do with the puzzle. I've converted a number of phrases this way into sha256 private keys, converted them to WIF, and no glorious "179..."


Enjoy Cheesy

Just tested it. The code works in Windows as well, you just need a C compiler (I downloaded GCC) and ran the results.

"Why 21 million? The truth is, it was an educated guess. The math worked out, or as close to it as I had wanted it to. Before settling  on 21 million however, I had considered making 100 BTC as the reward, and 42—the answer to life, the universe, and everything. But afraid that others would consider my reference to Hitchhikers Guide to the Galaxy a quip and at the expense of not being taken seriously, I changed it to 21 million," the author writes.

In This text he say why 21 Million
But watashi-kokoto have shit solution and only and Magic to disappear  Last Active: January 19, 2019, 03:50:45 PM

He say:
my approach
start with shit solution

SheIsCombingWithTheCombFeelsGood

then you can replace "The" with "A"
fill the extra space with new words

SheIsCombingWithACombThatMagical

then you can reorder

ACombThatMagicalSheIsCombingWith

or even

AMagicalCombThatSheIsCombingWith

put back "The", change "Magical" to "Magic"
