OK, lets spice things up a little bit.

Third wallet (with 6 random characters from a-Z) now has 0.5 BTC prize.

And I added the Fourth one with 5 random characters using only lower case letters from "a" to "z".

****************************   FOURTH   **************************

Bitcoin Address:
15p4qtmfRyTHfPYFRmhGYVGhP9FEZYrFsu

Encrypted Private Key:
6PfTCyR1k5FDHwFXm9Uch5aTGXLQQDtzbQt3sKxmN8i2HppJecyoHbzb9i

Password: 5 random characters (small English letters only (a-z))

Prize: 0.2 BTC

*****************************************************************

I will add the forth wallet to OP also.

Trying the second one with all 5-letter english words right now... All lowercase, I hope there's no uppercase letters Smiley

EDIT: Found it! The password was 'grAce'. and DAMMIT someone beat me by ~2 hours Sad

EDIT2: And I'm not even going to try the 3rd one. I can try ~20 passwords per second with my current setup, and I've calculated cracking it will take ~30 years...

Thanks for the fun challenge! Smiley

What tool did you use? Any good tutorials around?

i also would like to know about that if any thread or tutorials available to know how to crack that pib38, i got pib38 cracker but it's not working for me, any other good software for that?

Interesting challenges.

I guess it is almost impossible to crack the third one. I did some searches and math:

First wallet: About 800 4-letter names x lower/upper cases => 12k to 13k

Second wallet: About 9000 5 letter words x lower/upper cases => 250k to 300k

Third wallet: Exactly 52^6 = 19,770,609,664

The fastest cracker we have, Dirbaio, can do 20 tries/second. He will take about about 31.34 years to find! No one will commit this much energy and time to crack the wallet with only 0.1BTC, and therefore the puzzle will not be solved... unless minimalB is going to provide some hints.
omg what a long time will take 31.34 years to crack with your maths calculation but i think if someone have luck then can be cracked in 31.34 seconds. Wink

LOL! Very true! If you are lucky, you can generate a random address (with private key) and it may be the richest address!
i think luck is most important factor to get free bitcoins from cracking private key, but sometime skill works in that kind of matter.


Very much so.  You can get the key on the first try or on the last.

Wow... 2 out of 3 already cracked... good job guys! Yes, password for second one is "grAce".

I guess third one is going to be a little harder to crack : )

Well, no luck trying some random shots, neither compiling anything to bruteforce this... I'll quit for now and I bet when I come here later today there will be no more funds, lol

congrats to first person who crack that one, any guess for second key would like to crack it and trying to solve that math puzzle.

Second password is a standard 5-letter English word. It should be in any English dictionary.

bitcoin ... oh wait... =P

Can you give some hint like first and last letter from those four?

I guess you are already too late : )



Can you tell us what was/is the first pass?

Hey,

I'd like to figure out how fast BIP38 paper wallets could get cracked in case someone gets to them physically and tries to guess the password.

I created three BIP38 encrypted paper wallets with easy to crack passwords. Only small and capital English letters are used (from "a" to "Z", no numbers, no special characters). Say thanks when you get the money : )

I'll update this post with results when all three wallets are redeemed.

Happy cracking!
