BitCrack - A tool for brute-forcing private keys

[NotATether]

i say one sing you all think in a wrong universe of numbers it is simple math but also need to scan some steps we need to scan between the 2^x and 2^y numbers.

You shouldn't need to modify source code to search that range, just pop it as the keyspace range for whatever puzzle you're trying to solve.

Very impressive everything is working great..

[t0nyst4r]

I'm getting about the same speeds as clbitcrack + 3090 which is ~1350MKey/s.

Does anyone know the optimal 3090 settings (b, t, p, etc) so I can perform additional tests?

Also, is -c and/or -u needed if I am just feeding bitcrack a list of public addresses using the -i option?

do not optimize default is better then -b -t -p

searching compressed is by default no need to type anything for both type -c & -u

Thx. I guess I don't know if I need uncompressed or not. If I include it, it's a hit on performance.

Bitcrack CUDA 11.2 Compute 8.6 Win10

Would appreciate some benchmarks for RTX 30 series cards.....

Cheers

One thing I am noticing with this build of cubitcrack is that there is almost 0 CPU usage with multiple threads, even with feeding it a 500K list. With clbitcrack, each thread of clbitcrack was about a 5-7% hit on total CPU. Does this work get offloaded to the GPU or RAM with cubitcrack, or is there a problem with this cubitcrack and the work is not happening at all?

With some tests i came to 900Mkey/s with Opel CL i have 730MKey/s i think normal the RTX 3070 must have over 1.200MKey/s.

What Driver you are running?

Edit: Here is some Update if i change some settings: -b 46 -t 256 -p 5096
if i go over -b 46 it goes down to 850 also if i change the -t 256 only the -p 5096 you can set down that is the maximum you can get out.
with this seetings in open cl i got  1050.51 MKey/s with cuda 1236.66 MKey/s maybe for the future if any driver is not compatible you can use the OpenCL Edition but dont set the -b to high.

[willi9974]

can someone explain what the exact use case is?
- search for private keys in a list of thousands of public key addresses?
- search for a private key of a specific btc address ?
- search for private keys of a btc puzzle?
- other use cases?

[fxsniper]

No, BitCrack can not using public key address to find private key

- search for a private key of a specific btc address ?

Yes, BitCrack can do (up to you CPU/GPU scan)

- search for private keys of a btc puzzle?

Yes, BitCrack can (up to you CPU/GPU scan)
this one is same with 2

- other use cases?

recovery bitcoin if you lost but still have some information like range for key
scan lost bitcoin (if know closeup range or know position)

[willi9974]

thanks

so if i will solve the puzzle #64 i have to start with that parameter...

cuBitCrack.exe --keyspace 8000000000000000:ffffffffffffffff 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN  

is that right?


other question: if i have tweo cards in my system, can i user all cards parallel?

Correct on parameters; but you will need to play with the -b -t -p settings to maximize your cards.

You can't run both cards in same range at same time like -d 0,1; but you can split the range in to 2 ranges and run each card in separate range.

Example:

Code:

cuBitCrack.exe -d 0 --keyspace 8000000000000000:bfffffffffffffff 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN 

Code:

cuBitCrack.exe -d 1 --keyspace c000000000000000:ffffffffffffffff 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN 

or however you want to break up the range(s)

[pacnload]

is there any way to let bitcrack work with octal and not hexdecimal to create and check the adresses?

and one more questions why in base58 the code uses "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz" why the IO l and 0 (zero) is missing?

[pacnload]

IIRC it's not possible unless you modify the source code to support octal

and one more questions why in base58 the code uses "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz" why the IO l and 0 (zero) is missing?

Because those 4 character are visually similar. Here's information from https://en.bitcoin.it/wiki/Base58Check_encoding#Background

Code:

// Why base-58 instead of standard base-64 encoding?
// - Don't want 0OIl characters that look the same in some fonts and
//      could be used to create visually identical looking account numbers.
// - A string with non-alphanumeric characters is not as easily accepted as an account number.
// - E-mail usually won't line-break if there's no punctuation to break at.
// - Doubleclicking selects the whole number as one word if it's all alphanumeric.

okay that with il and 0o i understand but if i change the sourcecode with other since it dont work. is it maybe possible to leave the 8 and 9 and add an 0 like "01234567ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"

for the octal numbers if someone read this and have knowledge please let me know.

That's not possible. The base58 encoding is like an alphabet, it cannot be changed because that's how it's defined in the BIP for it and also the various encoders out there would not be patched for such a change in letters.

for the octal numbers if someone read this and have knowledge please let me know.

It's technically possible but why would you want to do that though? Octal numbers take up more space to spell out on the command line and also in output.

What performance maximum bitcrack can do on there card?

GeForce RTX 3070
GeForce RTX 3080
GeForce RTX 3090
or
GeForce RTX 30xx

and if price on market is over price most out of stock, if buy GeForce RTX 2080 x 2 double card is ok or not (if can find tow)

most sold out all (or sale with computer build-in)
GeForce RTX 30xx sold out
GeForce RTX 20xx sold out
GeForce RTX 10xx sold out

GeForce RTX 1080 ti x 4 card ok or not (very old card/ if can find / may be second hand)

I looking for card support with can do machine learning (high cuda core) main use not for bitcrack

bitcrack just hobby

Bitcrack CUDA 11.2 Compute 8.6 Win10

Would appreciate some benchmarks for RTX 30 series cards.....

Cheers

Hello,

So, can you tell us more about the code problem ?
Thank you.

Hello,

So, can you tell us more about the code problem ?
Thank you.

At some point, Nvidia made a change in the way their newer GPUs ran CUDA code which causes a fatal Misaligned Access error when starting Bitcrack, and he apparently made a patch for it that he wants us to test.

(Don't have RTX 3000 GPUs to test with, sorry richie.)
