Post: RE: 15 chars limitation

it would be less of an issue if combinator in hashcat behaved like combinator.bin or combinator in oclHashcat-plus. but, it would be even nicer if the a0 and a1 kernels just supported longer lengths. ...

Post: RE: 15 chars limitation

there's always a tradeoff, and a small loss of speed is an acceptable tradeoff to make something more flexible and more powerful. speed isn't everything.

Post: RE: Upgrade graphic card on PC, what to buy ?

You need to stress test the card under compute workloads, not gaming workloads. GTA-V will not stress the GPU anywhere near like md5stress or MD4 single hash brute force will.

65C is completely fine, why would you sacrifice performance when the card is not at all in danger of overheating?

Reducing temp from 65C to 50C will have no measurable impact on longevity.

you're assuming brute force, which no one would be dumb enough to do. a more significant measurement: 3 MH/s means we can get through rockyou in 4.7s, rockyou + d3ad0ne.rule in 90m.

maskprocessor is classic incremental, not markov. so you would want to use statsprocessor to see the actual generated words.

oclHashcat generates plaintext candidates on the GPU, and thus is not able to output candidates to stdout. So again, you would use statsprocessor.
