i,m trying to understand the option -stride and its affects:

1. is 58^8 the min and is 58^50 the max ? can the value be 0 or 1?
2. what if i lost say 10 chars or 11 chars from the end what value i shoud use for -stride, in this case i can not count for 58^8?
3. can we say that with -stride , we are trying to skip unneeded calculation so we reach faster. this is important to explain so the user can understand its value and function.

i have many amd gpu and it only work better with opencl
can u add it please for multi gpu
more than 10 gpu

thanks for all ur work

Hello
I've tested this wif solver and found that only works with legacy addresses.
For a segwit address (bc1q) there is no problem, because we can find the related legacy address with the same hash160.
How to recover the Wif of a p2sh address?

Hello Sir, im trying to run latest release version but get that message, kernel launch failed: ###.
im currently using older CUDA, thats GTX 1050 TI.
Can you please, teach me how to rebuild this for windows 10 x64 ?
i'm just new for C proggramming.
Thank you !!

Hi Pavel.
I am engaged in the implementation of similar projects to search for WIF keys and not only.

1. You are building on CUDA 11.5, so the program will only work on RTX3 GPUs... all other cards will have a carnel image error.
   Build like me on CUDA 10.22 will work on all GPUs.
2. I suggest adding a bloom filter to your project. You can take the finished bloom filter code for the GPU from me.
3. There are suggestions how to speed up WIF search by 5 times.

There are many interesting non-public ideas that we can discuss in the telegram group. https://t.me/+_mnQmgS1D5QyYmY6

Hi,
I am using RTX 2060, GPU driver and CUDA version are the same and COMPUTE_CAP=75. but I get device 0 failed.

Hello
How to proceed if the address is p2wpkh?

Hi there,

Are you tried to make the WifSolverCuda to Hashtopolis integration?
It will be helpful for a lot of projects. I hope they will be harmful to the integration.
They will share something with you too. Anyway.

Hello Pawel.
Is multi GPU possible?

Build
Windows:

Program was prepared using CUDA 11.6 - for any other version manual change in VS project config files is needed.
 Exe under /Releases/ was build using compute_cap=86, for cards 30xx. If you have older card, you must rebuild 
program using older CUDA/lower CCAP.

Linux:

Go to WifSolverCuda/ subfolder and execute make all. If your device does not support compute capability=86 (error 
"No kernel image is available for execution on the device"), do the change in Makefile (for example 1080Ti requires 
COMPUTE_CAP=61).

i was try to fix <Import Project="$(VCTargetsPath)\BuildCustomizations\CUDA 11.6.targets" />
in WifSolverCuda.vcxproj

but compiling failed yet after it

explain please where and how i may fix source code to compile for cuda less than 11.6 ?
thx a lot )

Hello. I suggest adding the time [00:00:00] to the toolbar on the left and adding total key on the right. [T: 1,754,976,610]
You can update the WIF position every sec.
It will be a useful addition if you need the code I can give.
Example:
[00:23:15] [L3UBXym7JYcMX91ssLgZzS2MvxTxjU3VRf9S4jJWXVFdDi4NsLcm] [C: 12.004%] [Speed: 1.2 Gkey/s] [T: 5,284,503,173,355]

Hi Pawel,

Could you please compile the program with compatibility for Nvidia A100 GPU?

Question : what i am doing wrong ? please help

Hi Pawel,

Seems there is no way to execute the software by selecting only part of the installed GPUs.
Like I have 4 GPUs and want to start the Wifsolvercuda only for 1,2 and 4 (for the software it will be 0,1 and 3)
I tried next
-d 013
-d 0,1,3
-d 0 -d 1 -d 3
No success.
Please help to apply the settings properly or make a new release.

Best Regards

How would we Calculate the stride?
I am confused on how to find the stride.

I have a private key that is a 56% match with the public address I am trying to recover.

I have the Private key of this address 156nQNtSdLMsng6HqTFiavcMb2uQLHP6VD and it is a 56% Match to the public key of this address 156nQNtSdLMsqD81zpjzzbHKonqgtBwVJq (Address I am trying to recover).

How would I calculate the stride for the address I am trying to the recover with the Private key and address I have now. Since it is a 56% match.

Please help me learn on how to find the stride for this.

Can you please explain the last release update with stride_1 feature ? how does this work ?

Hi! And if we don’t know first part of the wif , but we know that it’s compressed, it’s mean search in range 252-256 bit, right ?
