There are already Bitcrack binaries available for Windows that can be ran standalone. They can be downloaded at https://github.com/brichard19/BitCrack/releases/tag/0.31. Which one you use depends on what GPU you have. NVIDIA gpus can use cuBitCrack.exe or clBitCrack.exe, while other gpus can only use clBitcrack.exe.

AddrGen doesn't require a GPU and can always be ran. It just generates a bitcoin address and public/private key.

[StefanKing]

Thanks for your response. I will try them.
I don't have a faster GPU right now.
If everything gets fine, I will go for a high end new faster GPU.

Hi mates..
I need a help!
clBitCrack.exe runs fine but when i try cuBitCrack.exe, i get this error - cudart32_80.dll missing.. What am i missing?
I have installed cuda 9.1 already

Looks like you're not the first one to run into this problem: https://github.com/brichard19/BitCrack/issues/65

cudart32_80.dll means you need 32-bit version CUDA 8.x.By any chance, do you intentionally download older version of BitCrack since latest BitCrack uses CUDA 10.1 ?

He just needs to unzip the CUDA 9.2 installer using a tool like 7-zip, which he can get from https://developer.nvidia.com/cuda-92-download-archive?target_os=Windows&target_arch=x86_64, and then locate cudart32_80.dll, extract it and put it in the same folder as

(though maybe as you said the newer CUDA 10.1 has to be downloaded instead, I'm not completely sure which version is required)

There is no need to install the CUDA sdk itself, only that single dll is needed. Just get the local installer though, not the network installer.


If I can get on my desktop soon I can get the dll myself and host it for you to download. The CUDA installer is a 1.5GB download on Windows 10.

I am using the new version on bitcrack but I have cuda 9.1 installed. That might be throwing this error i guess.
Does BitCrack v0.31 support Cuda 11.1? Coz I have downloaded 11.1 by mistake instead of 10.1

Latest BitCrack version is 0.31 (when i write this post), where you can download it from https://github.com/brichard19/BitCrack/releases/tag/0.31
Don't forget to install CUDA 10.1

BitCrack is being compiled with different CUDA header and lib versions on Win32 (32-bit) configuration than x64 configuration. On x64 configuration they are compiled using CUDA version 10.1. However on Win32 configuration it is using CUDA headers for version 9.2 and linking to CUDA 8.0 libraries instead.

https://github.com/brichard19/BitCrack/blob/2f66852015d05441df2db7d9bd2b243f0836dd69/cudaUtil/cudaUtil.vcxproj#L83-L156 this is where all the build targets are defined. It pulls the CUDA_INCLUDE and CUDA_LIB properties from Bitcrack.props.

It means the binaries on Github were made with Win32 configuration, that's why it has these crazy dependencies. I guess since you don't have Visual Studio (correct me if I'm wrong) you can't build the 64-bit version, so I'll see if I can host those somewhere (assuming I even get it to compile, I'll need to fetch my own copies of the sdk)

EDIT: I couldn't even get past the CUDA toolkit installation stage because it was hanging on checking system requirements, sorry.

which is the best gpu do run this program...?? any suggestions ..??

[StefanKing]

I would like to know about how Save/load progress from FILE works?

EDIT: I couldn't even get past the CUDA toolkit installation stage because it was hanging on checking system requirements, sorry.

It happened to me aswell but finally got Cuda 10.1 installed and can run BitCrack successfully.

The more recent your NVIDIA GPU is, it usually has more CUDA cores which speeds up key searching?

How long did it take you? I quitted the installer after 20 minutes to be honest. I'm 100% sure my disk and cpu (or memory for that manner but installers never use a lot of memory) are not a bottleneck.

The progress file just contains the information in RunConfig struct https://github.com/brichard19/BitCrack/blob/2f66852015d05441df2db7d9bd2b243f0836dd69/KeyFinder/main.cpp#L23-L58 : the start, next and end key, the number of threads, blocks and points per thread, times representing status and checkpoint intervals (I think they are times between printing program status to console and the save file respectively), elapsed time of running and total keys and a few other parameters.

It's saved periodically in the save file so that BitCrack can continue its progress without starting all over if it crashes abnormally.

Thankyou I got it! I am just wondering if I can have more than 1 progress FILE.

It took me like 5~ minutes..
20 minutes!! I guess its a lot of time. You may have to check your drive for errors.

Okay.. here's another one. Don't know why I am getting these weird things.

Last time when I ran BitCrack (a few hours ago) I didnot see "[Info] Allocating bloom filter"
Now I see this like in image.. BitCrack is running though..
Any clue about this "[Info] Allocating bloom filter" stuff?

The bloom filter is used to estimate, inside the GPU, whether the reverse of a RIPEMD160 hash is inside a set of SHA256 hashes. Public keys of addresses are hashes with SHA256 followed by RIPEMD160 to get the bulk of the address (there is another part of it called the checksum that's computed differently but I don't think checksums are validated in the code). I think these things have more to do with the puzzle transaction.

I'm impressed I was able to understand what the source code is doing without ever running the program. I am a C/C++ developer, so it may have something to do with that.

i don't really believe in those brute-force methods, then you should have a dictionary that contains that combination, i don't think anyone in the world has anything like it, and if you want to get started with that then you have a super computer necessary, that is sometimes calculated, it takes decades to be able to crack something like this and by the time you have cracked it, the owner already has a new wallet that seems impossible to me

[zahid888]

Anyone have compiled Cubitcrack with cuda updated for 30 series of GPUs ?

It is just luck. Everyday i give 15-20 minutes to try, so it's like lottery and the bonus is: it's free to join 
However i tried the software with one of my empty wallet which i know the private key, i set the start point near of the private key and it successfully found it. It works and i like the thrill to try everyday.

Hey guys,
Can i hire anyone for $80 to help me with getting this easily loaded onto Vast.ai instances
Basically i want to try two things:
1) load a list of passwords and check it against another file containing addresses
2) Generate random public wallets and check them against a database for a match (which im guessing is what bitcrack does)?

Am i correct that since this uses CUDA it processes up to 1 million or more passwords per second?
I'm only trying this with abandoned wallets. I'm in serious debt in about a month and this is my last ditch effort (i know the odds)

Thank you

It is better not to waste your time and resources.

I might be able to put Bitcrack on your Vast.ai servers, send me a PM.

Basically i want to try two things:
1) load a list of passwords and check it against another file containing addresses
2) Generate random public wallets and check them against a database for a match (which im guessing is what bitcrack does)?

1) Bitcrack doesn't deal with passwords at all, it can only take in addresses to try to find their private keys.
2) Bitcrack doesn't use any database of addresses or wallets to check against. Again, it will only try to "reverse-engineer" the private keys from the addresses you give it.

Am i correct that since this uses CUDA it processes up to 1 million or more passwords per second?

The number of passwords that can be tried is highly dependent on the graphics card. Newer GPUs with more recent CUDA versions can obviously try more passwords than older GPUs. I've seen 1080Tis and 2080s for rent at Vast.ai.

You don't have any chance actually. I'm trying this with 21 million wallets & 450million keys per seconds. Nothing found for more than 2 months. (Everyday 15 minutes of testing). I'm not trying for dump someone's wallet, i just want to see it's possible to crack a SHA256 with Bruteforce.
