Help with btcrecover

[opies32765]

Hi everyone

I need some help with btcrecover and cannot find a way to contact the developer directly(gurnec). I have set up the program and its working. I have a second GPU that i would like to add to my computer. In the GPU acceleration info for the program there is mention of multiple GPU's. I went ahead and installed a second one but btcrecover is asking me to pick one it says --gpus names....is it possible to add multiple GPU's ? I have run the test and it sees both of them. I cannot figure out what the setting would be ? I have tried naming them but cannot figure it out. I have a GeForce GTX 1080 Ti and a GeForce GTX 1080 my info is below

cd C:\temp\btcrecover-master
C:\python27\python btcrecover.py --wallet wallet.dat --enable-gpu --global-ws 262144 --local-ws 1024 --tokenlist tokens.txt --no-dupchecks --no-eta --max-tokens 10 --typos 1 --typos-case --autosave savefile

thanks in advance.....

By default, btcrecover only uses multiple GPUs at the same time if they're identical, but you can force it to use different GPUs if you'd like.

First, ask it for a list of your current OpenCL devices like so:

Code:

> C:\python27\python btcrecover.py --list-gpus
#1 GeForce GTX 1080 Ti
#2 GeForce GTX 1080
#3 Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz

It's easiest to specify the GPUs you want to use by the #ID numbers, so for example to use the two 1080s, even though they're different models:

Code:

> C:\python27\python btcrecover.py --enable-gpu --gpu-names #1,#2 ...

Note that you may get better performance if you use a different global-ws for each GPU (with a bigger global-ws for the Ti), something like this:

Code:

> C:\python27\python btcrecover.py --enable-gpu --gpu-names #1,#2 --global-ws 262144,196608 --local-ws 1024 ...

Note that the order matters: in this example, GPU #1 (the faster one) is listed first after --gpu-names, so the larger --global-ws is also listed first. Only way to know if using different global-ws values improves performance is trial and error unfortunately.

Good luck!

hey chaps,

i too have been using the brilliant btcrecover software.

i have tested on a known password and it works (after 2 solid days) using several omitted characters.

for example i had the test password: Apasswordtotest

i removed the known end characters and placed the wildcards like this: Apasswordto%P%P%P%P

this solved the password. this was just a test.

however in my current case i has something like: Apasswordtotest??etc where the ? is the unknown password characters and unknown length.

the password is up to 40 characters long and i know around 25-30 of those characters.

any help will appreciated.

this one password holds the key for all my crypto wallets. some parts of this password are reordered and reused.

the current one i am trying is one of my BTC wallets.

sorry about the hijack opies, i am in a bind.

Hi do i need another version of openCL to read my cpu only my gpu shows up when i type --list-gpus? any help would be appreciated

What is your CPU? Is it an Intel or an AMD CPU? It might not have a compatible built-in iGPU... which would explain why it isn't detected as a "GPU"
