Thread: 15 chars limitation
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. |

However as the passwords on that list are only the ones that were found, I wonder how many of the "not found" hashes were > 15 characters in length?

Thread: Upgrade graphic card on PC, what to buy ?
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. |

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

Yeah I see what you mean. k/s can be easily misread as keys/sec. Maybe I should change this.

The remarkable cracking speeds you have are far more due to what you've done with SHA1 in GPUs, but there is this design flaw as well.

Thread: Agilebits 1Password support and Design Flaw?
Post: RE: Agilebits 1Password support and Design Flaw?
no, that's only half the issue.
the other half of the issue is that 2 blocks of hmac-sha1 are required to generate 320 bits, but only 1 block is required to validate the password. defenders have to d... |

Thread: Agilebits 1Password support and Design Flaw?
Post: RE: Agilebits 1Password support and Design Flaw?
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. |

Isn't the point of the OCLHashcat optimizations that these are being brute forced? Using a dictionary attack is a whole different ballgame.

oclHashcat always uses Markov by default everywhere a mask is used, unless you explicitly disable it via the '--markov-disable' switch.

your threshold would need to be less than 26 for this mask for it to have any effect |

Post: RE: I need help with syntax
maskprocessor is classic incremental, not markov. so you would want to use statsprocessor to see the actual generated words. |

Post: RE: I need help with syntax
oclHashcat generates plaintext candidates on the GPU, and thus is not able to output candidates to stdout.
So again, you would use statsprocessor. |
