I'm not sure what you mean by this. Could you rephrase?

Post: RE: hash160(x) a.k.a. ripemd160(sha256(x))

There is no way to combine hashes that I know of. It would be a very interesting and useful feature, but it might be difficult to implement.

    Thread: Hashcat & OpenCL... Why OpenCL?
Post: RE: Hashcat & OpenCL... Why OpenCL?

OpenCL is the framework that hashcat uses to perform the computation on the selected hardware. Without an OpenCL driver for a given hardware platform, you cannot use modern hashcat on that hardware...

FWIW, under Ubuntu 18.04 I'm also able to run hashcat well using the native packages. I have these installed: Code: -- $ dpkg -l | grep nvidia | egrep -v '^ii' | cut -b1-80 rc  libnvidia-compu...

Post: RE: Hashcat 1080(s) gpu error

Could be a power issue. Have you audited real-world power draw from the wall for each PSU under various workloads? How is the power balanced across the board and GPUs?

Post: RE: Hashcat 1080(s) gpu error

Hmm - that seems like enough headroom to me, on each power supply. With ~180W max per 1080 that's only 540W plus 460W for your mainboard, which seems like plenty. Only other thing I can think of: I...

Not sure what the root cause is, but if you change the the OpenCL directory and run hashcat from there, it should work (in other words ../hashcat64.exe)

I'm not clear from your post which tests are the ones that are for a large number of hashes. And to clarify, by "Optimized" do you mean that you are using the -O flag?

By default, hashcat expects bare hashes (without username). To ignore username, use --username. With -a 0, you also need to supply a wordlist. If you want to try the default mask attack set instea...
