ethereum: No devices found/left.

[henfri]

Hello,

I am trying to recover the pass of my ethereum wallet (only 0.2eth... So not a desaster :-).
I run:

Code:

hashcat.exe -m15700 $ethereum$s*262144*8*1*xxx*yyy h:\dict.txt --status --status-timer=5 -w3 -r h:\OneRuleToRuleThemAll.rule  -S -D3
hashcat (v6.2.5) starting

No devices found/left.

D3 is my CPU:

Code:

hashcat -I
hashcat (v6.2.5) starting in backend information mode

I assume something went wrong using the CPU and that is why no device was left?

When running benchmark, I get:

Code:

hashcat -b -m15700
hashcat (v6.2.5) starting in benchmark mode

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

CUDA API (CUDA 11.6)
====================
* Device #1: NVIDIA GeForce GTX 1060 6GB, 5228/6143 MB, 10MCU

OpenCL API (OpenCL 3.0 CUDA 11.6.99) - Platform #1 [NVIDIA Corporation]
=======================================================================
* Device #2: NVIDIA GeForce GTX 1060 6GB, skipped

OpenCL API (OpenCL 2.1 WINDOWS) - Platform #2 [Intel(R) Corporation]
====================================================================
* Device #3: AMD Ryzen 5 2600X Six-Core Processor, skipped

Benchmark relevant options:
===========================
* --optimized-kernel-enable

----------------------------------------------------------------
* Hash-Mode 15700 (Ethereum Wallet, SCRYPT) [Iterations: 262144]
----------------------------------------------------------------

Speed.#1.........:        0 H/s (13.05ms) @ Accel:1 Loops:1024 Thr:4 Vec:1

So also here, the CPU is skipped.
When I force it (-D3), I get No defices found/left.

With respect to drivers, I installed w_opencl_runtime_p_2021.2.0.616.exe
Before this, I did not get the CPU listed at all.

Best regards,
Hendrik

Hm... A reboot helped...

We can close this one.
