BitCrack - A tool for brute-forcing private keys

[citb0in]

well if ETH mining is profitable with 20 such cards and power consumption, why not... good luck.

[citb0in]

that's what I expected to hear. Yes, absolutely agree. If I were you I would use those rigs for cracking the puzzles. However, this will cost a lot of electricity and the chances still are very low to hit a key.

ETH can't be mined with GPU after the latest update, it shifted from POW to POS so people are now "staking" ETH instead.
But this is off-topic, just saying.

[citb0in]

that was my first thought, then I thought maybe he's renting GPU power at NH or similar. But that's really offtopic now, lets keep on topic

[italiandigger]

On Saturday I went to an electronics fair and I talked to professionals in home automation and solar panel installation. I am looking for a small house with a roof wide enough for panels. I've found one and i'm evaluating seriously to buy it. The geographical position in which I live allows me a good solar irradiation all year round, obviously more intense in summer.
The costs are as follows: a 4 kilowatt power system with 6-8 panels costs about 12-15000$ including assembly.
The technician I spoke to at his house has 14 kilowatts with 18 panels (I didn't even ask him for the price, the battery is around 6-10000$ used/new, like the tesla car battery).
Free energy in any case.
I'm also thinking of doing as in Siberia and putting 3-4 asic antminers in the cavities of the garage wall to warm up a little winter for free too.
Sorry, a bit off topic..

Your "gaps" are keyspaces much much much much bigger than mine (500/1500 billions keys), you could have more chance randomly with keyhunt-cuda, or with same size keyspaces randomly choosen (like i do).

[WanderingPhilospher]

if yall plan to post/use keyspaces searched by other people (lot of trust has to go into that) set up a python program that randomly searches whatever sized range and then print that range to a file; rinse and repeat. And then it's just a matter of posting your ranges somewhere for others to view.
As we all know, it is a huge undertaking as the td pool had searched 15%+ of the 64 key and still did not find it before someone else did.

Unfortunately I don't know how to program in Pyton.
I use the option of cubitcrack (--share) e.g. --share 23252314/25000000 (1500 billion keys for each share, it takes 3 hours with my 1060 3GB). I choose the share (e.g. 23252314) randomly with : https://xoomer.virgilio.it/roberto-ricci/variabilialeatorie/esperimenti/numeriacaso2.htm
Then i copy the keyspace from the terminal and i paste it on an excel list in progressive order.
I do that 1-3 times daily.

If someone from the forum with a good reputation posted their keyspaces I don't see why I shouldn't trust them.

Why BitCrack doesn't support new types of adress? (from '3' or 'bc' starting)?

And another quesion. Is this adresses also generating from the same space of numbers as P2PKH keys? I mean, that for example I have a private key
 

Code:

36a9e7f1c95b82ffb99743e0c5c4ce95d83c9a430aac59f84ef3cbfab6145068

For this key I have two P2PKH adresses  1AxSQFHqQ2nFUbZwcWSmHYrYumuQnK2nYG 12b9TofPY9R5gtKRUHBWjQrNP6mBYZuFqr. Can I generate also P2SH adress using this key?

The first address is generated from the uncompressed public key pair of that private key.
The next address is from the compressed public key.

Probably because it's designed to bruteforce the "puzzle transaction" (link), and the puzzle's addresses aren't p2sh nor bech32.

sure. The private key you mentioned results in:

Code:

Bitcoin address = 12b9TofPY9R5gtKRUHBWjQrNP6mBYZuFqr
Uncompressed Bitcoin address = 1AxSQFHqQ2nFUbZwcWSmHYrYumuQnK2nYG
Segwit address = bc1qz9k42yuypn3h0u98dfjw6frlxn3mhhc07pwhqg
p2sh segwit address = 31iwoQNky2ZMHEgYnTnARVmHEHArTqwLUq (corresponding p2sh script   : 0014116d5513840ce377f0a76a64ed247f34e3bbdf0f)

Thanks for everybody for explanation.
And any tool to take participate in loterry? I want random bruteforce of all keyspace, at a database of all BTC adresses with balance

I think about Hashcat, but it doesn't take secret exponent, in can bruteforce onli WIFs

Go with Keyhunt if you want to use CPU & RAM
https://github.com/albertobsd/keyhunt

And go with KeyHunt-Cuda if you want to use Nvidia GPU(Only)

Go to this thread to see the list of bruteforce tools: https://bitcointalk.org/index.php?topic=5422375.0

Those are designed for the puzzle transaction but you can specify the range if you want the whole keyspace. (which isn't comparable to lottery)

It wouldn't be too hard to code a fast (and optimized) Bech32 converter. It would have very useful applications in general-purpose wallet recovery software - not just for private keys, but say you have a lost wallet but all you remember is part of a password and a single address.

#2 released

Added support for compute 5.0 and compute 7.5
~20% faster generation of starting points
~1% kernel speedup

https://github.com/sp-hash/Bitcrack/releases/

Can you help me, your version of bitcrack doesn't see uncompressed adress. I have made test list with 2 000 000 adresse, and Bitcrack finds compressed adress well. I started with different option

• --compression BOTH
• -c -u
• -u

Even starting bitcrack with -u options doesn't help. It can't find uncompressed adress

[miku128]

KeyHunt-Cuda's range (--range) should fill in what is the largest？

[stalker00075]

Please tell me if the version of bitcrack would take private key from the file txt?

I have a large database of 10Gb+ private keys, can I check them for bitcrack? what would be the speed of the file?

- how much will it cost to be able to check private keys (sha256) from a file txt?

(I know about brainflayer, but its speed is very slow, (100,000p/s)

Hi. Which version of bitcrack works with the 3090ti ? I tried the latest version of cuBitCrack.exe from brichard19 but it did not work. There are no errors. Just nothing happens after running it.
