You may crack the password from a sniffed C/R pair. Now I need to clarify: my request to Sayantan to implement NTLM mask mode on GPU was for stored NT (aka NTLM) hashes, thus the nt-opencl format. Not any of the C/R stuff. I think that both stored NT hashes and the C/R protocol are sometimes referred to as "NTLM", although indeed they're different. Alexander
