Maybe someone can give me a WIF missing the last 12 characters and the public address, compressed or uncompressed, doesn't matter, so I can show that it works and not just me picking and choosing the WIF?

here you go

WIF:
KwLp2q49zihR4tgPrJaWSqcquiMhW2dRaXNkrM1F

legacy addressed compressed:
1CPHidfp1KfF79A54RA4MkMtdFwPSGjZwV

on my machine, it takes 3min to find the correct WIF with last 8 missing characters. But it would take a huge time for 12 missing characters at the end so I am curious to see your results and how much time it took.

Can you explain what you mean by 40 characters?
L2Dxz8UtQhVhC7WAedJRnoHYnhawTukMerG2XTpUdRHNkpQX2Nw4

and

8 or 9 characters in a month? Depending on location of missing characters, and if they are sequentially missing, which seems to be what you are referring to (a fourth of a piece of paper); 8 or 9 missing from the end can be brute forced solved in seconds. Missing 13 or 14 from the end can be brute force solved in under an hour.

I just guesstimated the 40 characters in a WIF from memory. Apparently it is closer to 50.

The 8-9 chars metric is independent of the WIF length and I basically multiplied 1 billion tries (keys) * 60 seconds * 60 minutes * 24 hours * 30 days.

CPUs of course cannot check that many keys per second but newer GPUs certainly can, particularly if they are used in SLI or whatever the heck NVIDIA calls it today.

Or used in Parallel ...

VBCR v2 ? which tool is this and where can we download ?

VBCR v2 on development stage.
If I'm not mistaken, it will soon be available for download here: https://github.com/WanderingPhilosopher/VanBitCrackenRandom2

Correct...

New GPU test and result (last 12 characters from WIF missing) for the WIF statement above:

I put a short leash on the -r (rekey factor, I used -r 500, so GPU was generating new keys every 4 seconds) to jump in and out of more ranges more quickly...I do not think there is a right or wrong; I was giving insight into the amount of rekeys and the slowed down hash rate.

There were 337,424,071,507 keys to check but the program only reached 152,672,665,600 keys checked before finding the key. Sequentially spread out over the range may have worked faster, or a lot slower. It's all luck when you get into these higher bit ranges, IMO.

Maybe someone can give me a WIF missing the last 12 characters and the public address, compressed or uncompressed, doesn't matter, so I can show that it works and not just me picking and choosing the WIF?

[EXIT] Reached end of keyspace.

Overall speed was quicker, but that is because the GPU speed was roughly 120 MKey/s faster due to no rekey involved. A small rekey chokes the GPU speed. But it had to check almost 50 billion more keys.
Why do I say it's luck? Let's say our beginning range was different. Let's move it up by 2,000,000 keys. New starting range of: 955179c4c20fadbaa6e568fc22badc890a8f6712844e51e2f0363442bfe94d99

A lot faster than the original. The point, it all depends on where you start and end your range check, how many threads (GPU grid size), and how many keys per thread you let it run...basically, all luck LOL.

Same for random...all about luck:

It's key to watch and tinker with your GPU grid size. I increased the grid size to 996,512 (now more random starting points( and almost found key immediately.

Smaller grid = faster counting but covers less of keyspace/range. Larger grid = slower counting but covers much more of the keyspace/range.

VBCR v2 ? which tool is this and where can we download ?

VBCR v2 on development stage.
If I'm not mistaken, it will soon be available for download here: https://github.com/WanderingPhilosopher/VanBitCrackenRandom2

As for right now, it's nearly impossible to brute force private keys. You literally need a quantum computer that will work 24/7 for that. So I think it's literally easier to just fish for the private keys.

Fishing for keys Grin

good one.

Depends on how many WIF chars are missing though. Right now you can brute force about 8 or 9 chars in about a month. There are ~40some characters in a WIF so this means roughly a fourth of a piece of paper. But it should be possible to brute force more chars with specialized ASICS (not the kind used in mining).

Can you explain what you mean by 40 characters?

and

8 or 9 characters in a month? Depending on location of missing characters, and if they are sequentially missing, which seems to be what you are referring to (a fourth of a piece of paper); 8 or 9 missing from the end can be brute forced solved in seconds. Missing 13 or 14 from the end can be brute force solved in under an hour.

As always, it depends on the program you are running and how much hardware you have.

I did a quick test, using random versus sequential (to make it a little harder lol). I took a WIF and removed the last 10 characters.

What is the risk of using root? Good thing I was unable to execute the given commands on that site, sometimes ignorance is a friend.😄

Using root to execute application is equal to giving application full access to your device. In this case, the risk is depends on whether CryptoXploit modify the binary/source to perform malicious task. Although in general, few non-malicious application would either refuse to run or cannot run properly.

There is no reason to run any computational program as root or administrator as all you will accomplish is making it easier for hackers to infect your system with phony copies of the software. You should actually run it from within a jail so that it can't gain any privileges with `sudo` or other stuff.

How to run BitCrack with linux

As detailed as possible here: cryptoxploit[dot]com/bitcrack/#

How did you find this guide? I did quick seems and few things seems to be fishy (or at least unusual),
1. This guide perform git clone from his own repository, not https://github.com/brichard19/BitCrack.
2. His repository seems provide both binary executable (for Windows) and source code inside compressed file.
3. The guide lack few detail (e.g. which linux distro is used and why the guide use user root on Linux).

First time using linux in life, I'm stuck at command not found using root@ or even sudo, lol can't even get to github from linux command shell. I wonder what this error is ~# lol

How to run BitCrack with linux

You have to compile BitCrack from source code. In past i tried to run compiled .exe with Wine, but i experience few problem. With cuBitCrack.exe, i receive error about missing .dll for CUDA library. As for clBitCrack.exe, it failed to detect any device even though i already install OpenCL device.

Why would someone try to run a performance program through WINE anyway. That's just dumb. Even if the CUDA or OpenCL drivers do manage to get emulated, the performance will be greatly inferior to the native alternative.

The program is no longer functional. Even though I double-tap the Bitcrack64 record, the software ends. My outdated GTX 1050ti is collecting dust. I could use it again.
-snip-

Those executables aren't supposed to be double-clicked, you need to run it in a command line.
If you're using Windows, that's either your "Command Prompt" or "PoweShell".

Also, "BitCrack64.exe" is only available in the very old version, the latest only has the OpenCL and Cuda versions (go to releases for the updated binaries)
Then, use "cuBitCrack.exe" instead.

Darn, I installed CUDA, now my RAM doesn't show GDDR5 in task manager, my GPU meter used to show temperature, but now it doesn't show that. Lol what have I done.

Did you install the correct CUDA version for your NVIDIA card?

When you install CUDA, it replaces your GeForce/Quadro drivers with CUDA-bundled ones. It's quite a mess, I admit.

That's what happens when your video card market consists of 2 or 3 vendors only.

I'm not sure if it was the right one, however I'm using unigine benchmark tool for now, might reinstall my old drivers and compare the results.
I just wanted a executable, I had to install VS CUDA, spending 2 days to figure out what compiling, building actually is.🤣

You don't have to download the whole cuda package, you can run the exe in a folder with vcruntime, nvrtc, and msvcp .dll(s) files inside the same folder.

For the CUDA10.props error; you can change your props inside the VS code to whatever props you have, such as 10.1, 10.2, 11, etc.
