Some would call everything in my GitHub repo beta...
The "bleeding-mask" branch currently lags behind bleeding-jumbo but it
has candidate generation on GPU for some fast formats (including NT),
although only when using mask mode. I think it supports some combination
of wordlist + mask though. Sayantan just picked up where he left so
hopefully it will evolve soon!
We do have a GPU version of "NETNTLMv2", but it's called ntlmv2-opencl
just to confuse people ;-) ...or rather because I never quite understood
the reasoning behind prefixing it with "NET".
Anyway it's slower than Hashcat but on the other hand it fully supports
Unicode as opposed to the tiny ISO-8859-1 subset Hashcat and others support.
MSSQL05 and others will be implemented as soon as that mask mode branch
has merged to our main branch. There's no point in implementing more
fast formats before that.
