Yeah I know vanitygen has been around a while but I found another vanity program called vanitysearch that is 10 times faster than vanitygen and 3 times as fast as bitcrack, at least it is with my 1080ti!

hey has anyone checked out vanitysearch?

With vanitygen I get 100MKey/s, with cubitcrack I get 350Mkey/s but with vanitysearch I get 1000Mkey/s and that's on a 1080ti

Vanitysearch has a starting point parameter but no end point parameter but I reckon the code could be altered for keyspace parameters

-snip-
Suggestions are always welcome.

The brute force way: Start @ ~607809 (multiplied the last known value by 1.7) convert to hex, create addresses, check if one address matches the next in turn.



What would be the best tool to attack this in a brute force way while we all think on something better or discover a easier way?

Some GPU bot would be the best to brute force it, like shorena was saying.

Need to code one, but I'm not in the mood now Smiley

Anyone out there doing it? Or maybe there is something existing?

I think the best existing tool currently is yours or otherwise private. I would think the best way would be to modify (ocl)vanitygen according to BurtW's suggestion. You would need to limit the random number generator to a certain amount of bits and keep the rest.


Yes lol ... vanitygen is being checked since 2015, early days of the "~32 BTC prize to who solves it"

My previous hopping speed was around 110000.
> I removed text files wild.txt and tame.txt
> gained speed because  
 A) I update wild and tame lists outside calculation loops
 B) I do not check collisions (comparator)  at each step in the while loop, but only  once every cycle (if (Hops % Cycle) ==
  
One more thing, you can experiment with different tame and wild kangaroo herd sizes Nw and Nt.

I've optimized the code. Hopping speed improved about  50% per core.
with 4 cores I've reached 850000 h/s.
Timing:

maybe i sad wrong, i need all keys and adresses which bitcrack goes to save

No, bitcrack saves only the address to the found private key. It does not save all the generating keys.
But the code is opensource, you can add the file saving to the code and make the compilation.

What is your reason to save all the generated keys and addresses?

-o, --out FILE
    Append private keys to FILE, one per line

can bitcrack save adresses in file or only private keys?
to this file bitcrack record found addresses with keys.one per line.can also be called as you want -o 1out.txt, -o myrich.txt ,etc.

try to use this function, but don't see files that bitcrack record, where is it saves, in bin??
in windows it saves in the same folder where the bitcrack is located. the file is created as soon as at least 1 key is found.

The Cuda version is 10.1.

When I used Cuda 9.0 the BitCrack was not being able to launch, and I don't know how to change the script itself to use other Cuda version + on Github it's written that you need Cuda 10.1 and Visual Studio ? Or anyway to resolve this Cheesy

try running cudaInfo.exe at first... you need to identify your ID of that GTX 660 card, which you will have to use as parameter with cuBitCrack.exe --device xx

make sure you also have Nvidia CUDA 9.xx or 10.xx installed according to what version of BitCrack you are running

can anyony told me how to use --continue to save a result of scan private and addr?
or mb show a command?

 use first time -  xxBitCrack -c -u -i target.txt -o finish.txt --keyspace 1:FFFFFFFFFFF -continue step.txt
 and after       -  xxBitCrack -c -u -i target.txt -o finish.txt -continue step.txt

How do u guys convert hex to wif? offline?

this converts lots of stuff.  save and run offline.

download one of two or both and convert offline.
click on the bitaddress.org.html,index.html in the folder and here’s your offline local site.

Thanks for answering, but I already downloaded them.
But I just can’t understand how I can do this from 0x01 this is KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU73sVHnoWn hmmmm
