BitCrack - A tool for brute-forcing private keys

[NotATether]

Say sp_ does add the code for pooling Bitcrack one day (though I doubt it), if somebody fires up a cluster of say 100 Windows boxes with 18 GPUs in each, its only a matter of time before Windows restarts itself for an automatic update.

Bitcrack is a simple terminal program. I think it's possible to run it on linux in Wine.

Dude you're kidding right?

It is by no means a "simple terminal program", hardware acceleration from the GPU driver is a mission-critical part of this program for its peak performance. Bitcrack does and I have seen it slow down massively because of bloated debug libraries, so I can only imagine how crippled it's going to be when every CUDA runtime call is going to be instrumented with 3x more instructions just to emulate a Windows API - that's exactly the kind of shit we're trying to speed up.

We already incurred a speed penalty just to make it work for RTX cards and the last thing everyone needs is a even slower program just to get it to run on Linux.

This isn't like the GPU mining business where you can get away without source code like PhoenixMiner devs did, because you can't direct shares to a different address in the first place. Trust in key crackers is essential because there's nothing stopping someone from wiretapping the private key over the network after its found.

I don't think there's a special relation between the patterns in the digits and the private keys, because they are random numbers anyway and as such it is not possible to influence the digits of the result, else it wouldn't be so random anymore.

Is there any way to generate all privat keys with compressed and uncompressed and save them to txt file with 100MB Splited size?

starting from:
000000000000000000000000000000000000000000000001A838B13505B26867
ending on:
000000000000000000000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

Then you are doing something wrong.
My first RTX 3060 card has arrived and I will make a fix in bitcrack sp-mod #6 (windows) with fullspeed wine support.
spminer #2 for vertcoin has already been released with rtx 3060 support. Mine fullspeed on x1 riser cables and latest drivers without NVIDIA blocking you.

So.. when your sp-mod #6 will arrive ?? hope very soon we will get rid of that message (Error: misaligned address).

I guess you have an RTX 3000 but you're waiting for me to make the exe right 

I'll try to find time for it today. Been struggling off and on with incremental backups on the box it's supposed to compile on so that's been eating away at my time.

[willi9974]

i have two 3070er cards a i waiting too :-)

[pacnload]

is there maybe a way to compare a list of bitcoin adresses i have generaded with a list of adresses with balance?
if i check it online with some tools i need to long to check for balance. the better way is to compare 2 lists but do know  someone a way to do this?

Yes i was trying to compile your source code but i can't

download it .......
My computer check 1 address in 36579687 address ( balance > 0.00000001 BTC ) only 1~2 second

Code:

$ wc -l blockchair_bitcoin_addresses_latest2.tsv
36579687 blockchair_bitcoin_addresses_latest2.tsv
 
$ time grep  16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN  blockchair_bitcoin_addresses_latest2.tsv

that is a goog question. is it possible to speed that up, comparing two list with millions of lines?

[NotATether]

If you sort the file and use binary search to look for each item in your list then your runtime becomes O(log2(n)) for each  for each entry and so you're going to have a maximum of O(NumberOfAddresses*log2(n)) as your worst case runtime. It's really not slow, that's about 30 units of time to search for an address in a list with 1,000,000,000 lines in it.

Actually fitting all that into memory is going to be a problem though. There are some algorithms I read in a Knuth book about on-disk sorting but they're very old and I think they may have to be adapted for hard disks instead of tapes.

i have generated 13million adresses with some settings i think that can be usefull and i need to check it against some other list with adresses with balance
now the only thing it must do is check it one by one or maybe if it use memory maybe 1.000 by 1.000
i also tried to use an text editor that can compare 2 files but it wont work and i think there are many scripts written in python that can do it but i dont know where i must search for. it not must be an bitcoin programm.

or i need an script that works faster to check the balance on websites. maybe there is an website i can search with an connection for a small price to search for. the problem is the timeout of the websites. i think the best way is to compare with an list of balance but i dont know what script i need.

Use awk. I use it on windows. Download git for windows if you run windows. Then compare two files.

Is it possible when we use someone's compiled version of bitcrack and they modified the source code like that "if addr is = 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN email me xyz@hotmail.com and print reached end of keyspace" something like that So We do not know that we have solved the key. And does the compiler get the key without knowing us

yes , compiled exe can do it .... only use net socket connect to his server....
like Trojan Virus .....
but 0x8000000000000000  is very big number ....
we have no super GPUs to find  #64 private key .... possibility is very little

Last few characters have little similarities if we are able to guess few characters of key from back or front we will be able to solve atleast p64.

but dont send the WIF Code

Guys on Windows I'm getting an error about some file called "Cuda 10.2.props" is not found in this location:

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\BuildCustomizations\CUDA 10.2.props"


I guess it's time for some hackery inside the .vcxproj files to remove this reference

Huh? It simply means you don't have 10.2 loaded on your machine. No hackery needed. Just download 10.2

Or change the reference to whichever CUDA you are running. 10.0, 10.1, 11.0, 11.1, etc. Not sure it will compile with the 11s though.

Can possible port BitCrack full version to BitCrack Lite version for small version cpu and port again to mobile device, android for convert old mobile device unused to be BitCrack android

That's a bad idea. Continuous CPU usage of phones while they're charging will deplete the battery's maximum capacity. Besides a phone doesn't have enough memory to run it anyway, even when I use -b 1 -t 32 -p 1 I'm still using about 100MB+ of video card memory (not RAM, remember that. Embedded GPU chips don't have that much VRAM).

I just think how can useful some mobile phone unused

but if can port to be lite version for using on low memory low space or no GPU device may be help to can use on many device
