Finally I managed to find the solution by searching 5Juu2CkB3XFdBzEcyH9dypNhDZ8fXgh6RQwwbo5* in 3h:50m:39s using an Intel i7-4xxx Smiley

The solution is:
#3 = XFdBz
#9 = ueBaf
#10 = eGYoMm5

I thank you very much for this interesting puzzle.

Congratulations! Did I read right that your bruteforce tool solves at a rate of 100,000 keys/s?
Yes and no. I created one bruteforce tool which could do 100,000 tries in one second which was being used for finding brain wallets only.

For this challenge, I created another brute force tool which did following:
1. Split the guesses in many batches
2. Assemble the first guess in the batch as a base58 string
3. Then do a base58_decode which outputs a 37 byte binary
4. Take byte #1 to #32 (counting from #0) and load it into the EC library (yes, you can ignore the checksum here)
5. Do an EC point multiplication p=G*k where p=public key, G=base point and k=your first guess
6. If ripemd160(sha256(p)) matches target, alert and stop
7. Do an EC point addition p=p+G and goto 6. until 58n/232 repetitions has been made. n is the number of characters missing at the end
8. Open a new batch and goto 2

This gave me the boost to try 500,000 valid keys in one second.
My computer found the key in under 4 hours instead of cracking for days because I told the bruteforcer to try a limited character set first. It was:
  • Alphabet 6Fabcdefghijkmnopqrstuvwxyz for puzzle #9, char #1,2,4,5
  • Alphabet 6abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ for puzzle #9, char #3
Puzzle #10 was auto-solved by the ECDSA point addition loop.


I would be happy to hear from the anonymous cracker what his/her approach was because I'm curious.

Congratulations ! ! you're the Second one to crack the Cipher! but the first one to keep the BTC Smiley Job well done!
Great BTC adress mate Wink

Thanks to everyone who have participant ! i hope you enjoyed the Cipher !

Congratulations! Good work Smiley

Can I ask who was the first one to solve the puzzle? Was it Coblee? Did he make the donation after solving it? Smiley

EDIT: I see now it was already solved a month ago, didn't even notice that Cheesy

i have no idea actually who solved it the first time, i only got a Anonymous PM haha but i'm sure he/she is here somewhere.

glad you guys liked it. i might make a new Cipher soon, but at the moment i'm focusing on this project  https://bitcointalksearch.org/topic/operation-caeluswe-will-send-a-bitcoin-satellite-to-space-escrow-1183158 (sending a Bitcoin Node to space)

but i'm very eager to  make a new cipher right away tho. we'll see Smiley

There's a lot of Intellectual people here, so if you wanna take on another challenge while you crack the Cipher you should take a look at my other project as well Smiley

I found this puzzle today.  Looks like you solved most of it.  My take at 3:

Page(Word)-Letter-

counting numbers as words and skipping headlines gives

XFdBz

(x of flux, f of family, d of discussed, b of but, z of zygotes)

Note: page 192 seems to be 207 in PDF (the offset is not completely consistent, but 192 is the start of the chapter according to the table of contents).  The other pages have an offset of 16 and there are numbered pages in the vicinity.

Did you try that with some of the other combinations for the later uncertain ones? I have a feeling somebody will be claiming this prize soon Smiley

i'll keep this short, i've made a cipher, anyone who can crack it will receive 0.56 Bitcoins. Depending on how long it will take you i might increase the reward over time Smiley (timer 30 Days, after that i'll decide what to do)

here it is !

I think there is some information in there on what to change in the code?

"from simple to complex" -> ...
"from the lower to the higher" --> upper and lower cases
"cyclic changes" --> Maybe changes in other parts of the puzzle apply here as well?

hey guys can any one here kind enough to tell me what Cipher is? Tongue
I really don't know and has anyone cracked it that's mentioned by the OP?

From wikipedia Wink
Quote
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure

Yes, someone did crack this cipher but didn't want the prize(rich/kind?) Cheesy
So, he sent back the cipher prize so that other people can enjoy it Smiley
