BitCrack - A tool for brute-forcing private keys

[BiT_black]

#2 released

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

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

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

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.
MSI GeForce RTX 3090 Ti Suprim X 24G
Driver - 527.56
CUDA - 12.0.94

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

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

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.

Maybe? ...

Put that on our list?

I use bitcrack with 2gb file & large address database without any problem, bitcrack only support bitcoin address start with 1
as per speed it depend on what GPU you using.
For cost depend on hardware & how many address you want to check.

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?

Did You crreate them mnually or using bitcrack?

Interesting repository, I see some of my tools there but also some interesting codes, I will check some codes there because they implement libgmp.

Thanks

Did You create them manually or using bitcrack?

Using secp256k1 library: https://github.com/AlexCurl/bitcoin_tools/blob/main/ecc_gmp_C/main.c

https://github.com/AlexCurl/bitcoin_tools/blob/main/secp256k1/secp256k1.py

Could numba be inserted into this code? I have not yet seen secp256k1 that the calculations go through @jit - that it has full GPU support.

if you are on python just use this library: https://github.com/iceland2k14/secp256k1
fastest out there for python since .dll(Windows) and .so(Linux) are shared libraries containing compiled functions written in C++ ready to load and use.
Most my codes that are there just good for testing and research. That is what I do mostly.
For CPU best option is VanitySearch code base it is the fastest.
It is in C++ and easy to understand and use.

I want to make one that will do 300Miilion Key/s from python. One or more GPUs....The only way is through numba and jit.
https://numba.pydata.org/
And there is nowhere an example of how to calculate secp256k1 through @jit . These are simple mathematical formulas, not rocket science.
It's as if someone doesn't want this to speed up on purpose.

It is likely that another program will need to be developed to handle the remaining keys between #64 and #160. Bitcrack does not seem to be capable of solving any more keys and is no longer effective.

[hZti]

For home desktop computer way too hard.

If there is no new version of bitcrack, than we will simply have to wait a few years until home computers have the power to solve it. Sooner or later we will even have to worry about the security of usual bitcoin adresses, but this will be in a few hundred years maybe. Until then there will be a solution. Even right now you could just make the bitcoin addresses a bit longer.

Hi, i have a laptop with nvidia gpu rtx and i tried cuBitcrack and i get only around 150 Mkey/s and with VanitySearch i get 450 Mkey/s , but i want to use Bitcrack as i can save progress. Is there any chance to get more Mkey/s with cuBitcrack? I need different version or to make some settings on it for higher rate?

what are your bitcrack settings such as:  -b 96 -t 512 -p 1024
that will help the community better assist you.

hi i used deafult and i tried this  -b 96 -t 512 -p 1024 get out of memory and  tried  -b 96 -t 256 -p 1024 i get 395 Mkey/s now. should i try different one? anyway thanks i get more x3 speed than before with Bitcrack

yes, you should experiment with your GPU, since each one will get better performance using different settings.

[yoshimitsu777]

what is the difference between bitcrack and keyhunt?both work with cuda and keyhunt delivers the higher rate without exception.
what is the reason for this?
why therefore do not most use keyhunt from albertobsd for cracking the puzzles?

If you are referring to keyhunt-cuda, albertobsd did not program it.

Why people still use bitcrack, maybe for the stride function...I'm not sure.

[yoshimitsu777]

https://github.com/albertobsd/keyhunt

i did think albertobsd developed keyhunt - sorry.
in my tests keyhunt-cuda is always showing higher performance and rate so i do not understand why some people still use bitcrack or bitcrack2

what is the best tool in term of performance rate in your opinion to use for trying to crack puzzle 66 where no pubkey is known?
