Hashcat CPU has parts of ASM. For oclHashcat-* its plain C for the host-code part, OpenCL for AMD kernels, CUDA for NV kernels. Both OpenCL and CUDA and nearly 1:1 to C. There are also some parts of ...

Post: RE: What linux distro do you recommend?

hashcat is a 32 bit only app and you are on 64 bit linux. so you need to install 32 bit compatibility libraries. maybe this helps: sudo apt-get install ia32-libs

I think he's talking about cracking vbull hashes. You can crack them with hashcat v4.0.1 in mode 2611 (not 2711) when not using -O.

I've explained that in detail in the hashcat v3.00 release notes. If you don't work on the system -w 3 is fine. With -w 3 it should be ~96ms, but that's possible only with enough amplifiers. With stra...

You will not be able to do anything on the desktop. I'd still recommend -w 3, it has several advantages

Propably because of host process can't load words from dictionary. You might want to retry with -a 3 and see if it still happens. If no, then that's the reason.

Older version do not work anymore because of the timebomb, thats why I removed them from download section. There is no way around updating to a more recent GPU.
