Full Version: Speeding up prince

I hope I can get some insight into whats going on in this situation.

I'm using pp64 to feed into hashcat. When compared to using just a regular dictionary, I'm seeing a huge performance decrease.

(alt use for a mining rig):
i3-7350 4.2GHZ
8G ram
6x gtx1070

I see my ntlm hash rate go from ~4000kh per card, down to around 1200kh per. (dict vs prince) I figured the speed change was because I'm piping candidates serially, so I added 2 rulesets to help create more work, but the hash rate remains the same.

Aren't the rulesets processed in the GPU? I would have expected the hashrate to increase since each password from prince would be exploded into a thousand permutations.

Any suggestions on how to speed it up and info on what going on would be appreciated.

Thanks!
How big were the rulesets? Do you get better performance if you add a larger ruleset, like dive?
OK, my apologies, due to the late night last night I was *way* off with what I thought I saw; things look to be working just as expected.

Thats nearly 10G/H

For comparison, here it is with a wordlist and a single ruleset:

Prince and a couple rulesets have my rig pretty flat out. Smile

Thanks for getting back to me!!
You're welcome - enjoy!
