OpenCL version is known to have such problems. Someone must fix the code. I only use CUDA version.

That's right.

the program skip private keys in amd rx580 but working fine with nvidia gtx 950m
anyone knows why?

amd rx580 command :
clbitcrack  -c -u -i test18.txt -o out.txt --device 1 --keyspace 2:FF
...
The clbitcrack has nothing to do with your AMD GPU. In order to utilize the GPU for this task you must use cuBitCrack.

He can only use the buggy clBitcrack with amd gpu.

No one answers? !!!
Answer at least my question:
I've overclocked my graphics card
Has it affected my graphics card?
And the output?

I wonder can it be used for cracking fpga acceleration cards such xilinx alveo, sqrl bcu 1525 or reverse engineered chinese asic-s such blackminer f1 ... they support opencl ... Huh

Hello, would it be possible for someone to modify the program so that instead of searching for the bitcoin address he searches for the public key (compressed) in its hexadecimal form without the prefix (02 or 03).

Example: we know that for private key N°1 (1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH) the compressed public address corresponds to: 0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798
I would like BitCrack to search for this public key without the prefix 02 at the start (basically it searches for the X coordinate only)

 My goal here is not to find the private key of an address but to search (try ^^) to find a correlation between private key and public key. I know that at the moment of today certain think that it is impossible (and they are certainly right) but I would like all the same to carry out certain research and that is why I will need to modify the program. Unfortunately my skills in C ++ and even in python for that matter leave something to be desired. Thank you in advance for the help you could give me or any external link not too complicated to implement. Thank you

Bitcrack is not made for that but you can use this for what you're talking about but the speed is not with an gpu though.

first of all thank you for your answer, I knew all these utilities and I have already had the opportunity to test them. The problems that I encountered with Pollard kangoroo are that on the one hand it does not use the GPU and that I do not wish to search for the private keys with their prefixes (02 or 03) but only the coordinate of x which is elsewhere calculated in the first step before check if y is odd or even. The ideal would be a model like bitcrack which randomizes a private key in a range and submits it to the elliptical curve and checks only the coordinate of x. I think it must be possible right? thank you again for being interested in my problem.

BitCrack does not authorize private messages from noobies like me, I allow myself to send him my request here ^^ which incidentally and always the same as before (I don't let anything go - lol)

Hello,

First of all I want to apologize for my English which is not necessarily at the top.

I had the opportunity to try your program and I want to congratulate you because it is really effective.
On the other hand I would have liked that this one seeks only the coordinate of x and not the bitcoin address in its base58 form.
I think that after all this must be faster (I can be wrong) because it is the first thing that this one calculates after having given him the private key. So instead of providing a list of addresses
(eg: 173g6UwTFYWKrks6h4waxNdCewsPWeLuUo), I would like to be able to provide him a list of coordinates x (ex: d41255c006185d9dd1ab6eccef02bf8a6b8cc7e20cffbe84b8e0b6) and that the program in the same principle as currently checks the correspondence. Unfortunately after consulting the source code I am unable to make the changes. If I understood correctly, the modification should take place in the function:

void KeyFinder :: setTargets (std :: string targetsFile)

where the addresses are converted to hash160 before being checked. this function would therefore not be necessary for my use as well as the others (base58 - sha256 etc ..) only the ECSDA function interests me in this case. My knowledge of C ++ is close to zero and I am unable to modify anything (it is not for lack of trying ^^). Ok, would you be kind enough to modify it or at least provide me with a piece of code or some details that could allow me to modify it?

I will understand if you do not have the time or the will and would be grateful for the work already done by sharing Bitcrack.

Your biggest fan ^^

this request having become public, any charitable soul is of course welcome. thank you in advance

WIF is just another representation of the private key (In other words, they are the same thing)

I can help you to restore/recover your wallet or password.

But 'alphabetical' checking of WIFs is not this same as 'alphabetical' checking hex pkey....

Of course not, WIF has way more permutations than the possible priv keys.
