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

No way! Br... |

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. |

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... |

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.

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

| yep, 5xxx series was super prone to ASIC hangs with even mild overclocking. there's not much headroom on those cards. i don't go higher than 880 Mhz on my 5870s, and that's with overvolting. |
