    Thread: oclHashcat-plus v0.09b52 speed issues
Post: RE: oclHashcat-plus v0.09b52 speed issues

NV has done something to either the driver, or to the cuda 5.0 toolkit. Litecat, v0.10 release vs 0.11b20 is always a bit slower in all algos, except LM and old oracle 7-10g. Rolling back to good ol...

    Thread: no faster WPA2 cracking?
Post: RE: no faster WPA2 cracking?

So, technically, Solar Designer was wrong, it is usable with WPA2, it simply will not be practical, since you'll get a tiny increase(0.002%) in speed. But for algos with low iteration count(by low I m...

Post: RE: catalyst 13.1

I remember similar situation with NV. When they released CUDA 3.2(which required 260.xx), there was a HUGE speed loss, but oclhc was using OpenCL for NV then. I was using the old version of oclhc and ...

Post: RE: can't crack wpa even if key is in dictionary

I have tried to reproduce using plus and hc, and also with third party software. None found the password as "mercedes1" Mayhaps its not "mercedes1" ? Or the hccap is corrupted.

Post: RE: Breaking AIX hashes with hashcat

I like how md5-based variant is more secure in terms of computation than sha-2 based variant.

Yeah, it's basically multiplying shaders by their clock, but comparison is good between a certain generation only.
