Descrypt 8 Char PW - 512bytes - 11-29-2017
How long would it take to crack an 8 char DESCrypt password composed of ?a?a?a?a?a?a?a?a using a GTX 1060 ?
RE: Descrypt 8 Char PW - royce - 11-29-2017
I couldn't immediately find any public benchmarks on 4.x hashcat for a 1060.
If you happen to have one, run that actual attack and check the time estimate; that will be the most accurate way to get your answer.

OK, the card doesn't arrive for a week or so. Its was either a GTX 970 or 1060, and the 1060 seemed a lot faster.

undeath, cool - yours? Was that under -w 4?
Here's one for 6x 1080s, -w 4:

Thanks for the benchs.
I saw a benchmark on the GTX 970:
Hashtype: descrypt, DES(Unix), Traditional DES
Workload: 128 loops, 256 accel
Speed.GPU.#1.: 89998.0 kH/s
Why's it so much slower than the 1060 ?
RE: Descrypt 8 Char PW - royce - 11-30-2017
Faster base clock (1708 MHz vs1050 MHz) ?

RE: Descrypt 8 Char PW - 512bytes - 11-30-2017
Ah, good that means I can OC and get more speed.
RE: Descrypt 8 Char PW - royce - 11-30-2017
For a single 1060, it will still take four months, I would think.

Yeah, Im thinking of getting x2 1060s and a 1070.
Once done I can put them in to a secondary PC (which has an old GTX 260 at the moment).
