Solve a riddle, guess a 4 char password and add 10 BTC to your xmas... SOLVED!!

[CIYAM]

Why would he deliberately generate 1Cpu?

Actually I didn't - that address was just a complete fluke (used ./vanitygen 1) - but good try - final hint not far off.

I think the password is 1Cpu

But since the logic of generating the hash isn't clear, it's hard to figure out the hash. And even if we know the password, without the clear logic of generating this hash its hard to crack the gpg priv key.

From his post above:

Hmm, seems to be more of a challenge aimed at programmers with the highest spec machinery, which I am not, than a riddle.
I'll keep at it any way in case I get lucky.

Generates a key.
Uses first chars of it to generate a hash. Something like 1Cpu1Cpu1Cpu1Cpu or simliar.
Creates a pgp priv key
Encrypts the bitcoin priv key with the gpg public key.

If the password is random.. Then simply good luck cracking it without knowing the exact logic.

[CIYAM]

Actually the password really isn't so random (but the main part of the riddle/puzzle is really the "equation") but I am not going to give away anything more about that unless it isn't successfully brute forced within a day after the next hint...

[OpenYourEyes]

0x5E? :p I'm looking at your keys/IDs for clues.

Looking forward to the next hint to the equation. It's had my brain baffled for days.

[AwkwardSituation]

The Answer is 42.

Therefore, the 4 character password is

a#42

[CIYAM]

Okay - am pretty sure this should be the final hint:

Code:

1p+1p=2.p

and Go!

So, I've put my mkpwds password generator up on my misc github repo, for anyone who's interested.

It's not as fast as the python one described above but it does work and when piping to JTR I don't think it slows down the process. Seems to gen about 127k pwds/s and I was only getting about 61k pwds/s on JTR with my GPU.

I think I'll kick this whole 'at least thing ' out of my equation. But there are still infinite ways to make a second string out of string + string...

Not sure, but I see a chance that this wasn't your last hint, sir^^

[CIYAM]

hmm... seems my way of thinking must be very different to the people trying to solve this puzzle....

let's try this then...

Code:

1p+1p=2.p
       ^
(my wife thinks I meant something else here *and* the equation is how you might/would "write" it down on paper)

Do they still teach writing these days  

Is this the reason no-one has guessed this?

Let me list some simple math operations....

1. addition
2. subtraction
...

I saw this as a regex dot and could be any char. But now I've mended my ways and changed my pattern list. Still a lot of variants possible.

and updated again... going once, going twice....

Sounds like you are referring to some rather rout of context transformation such as

"one %s plus one %s equals two %s"

The possibilities are too many.
With or without spaces
"plus" / "sum" / "added to"
"equals" / "is"

And the whole "at least" thing suggests that either there are more elements in the equation, or the equation make rather little sense.

I think most ppl trying to crack this are rather technical in their minds

[CIYAM]

Think of a type of graphical window system that has one letter...

[BkkCoins]

Also not sure just how literal to take the clues. One may have a general idea but since even one char slightly off ruins it it's easy to scrap an idea out and try another tack.

[CIYAM]

We have a winner!!!!

Now you are suggesting that you use X (Capital letter x) as multiplication operator!  

A lower case x would make just a tad more sense. Not much, but still

Come on guys - let's finish it up:

Code:

1p+1p=2xp(at least)

I've been scanning on patterns just like that for a while now... nothing yet.
I mean I've even got everything ready so if I get the pwd I can extract the key and import and sweep it lightening fast. This is when you want that 400k p/s!

[BkkCoins]

Damn It. Just found the key and it had been swept already!

Must have been just seconds....

I wonder if I could issue another spend with higher fees and have it go to me.... ha ha.
It's still unconfirmed.
