Thread: 1Password Competition
Post: RE: 1Password Competition
| Yep. The only way to make real progress on it would be if multiple teams with lots of cards all cooperated. Which would itself be pretty cool, IMO. |

Thread: 2x Nvidia for opencl - SLI link necessary?
Post: RE: 2x Nvidia for opencl - SLI link necessary?
| Not necessary - in fact, definitely do not use SLI with hashcat.

Thread: 3DES Known Plaintext - How?
Post: RE: 3DES Known Plaintext - How?
| Separate from your syntax issue ... have you done the math of how long it would take to exhaust this mask (if it were even possible to run it with hashcat)?

Thread: 4 card cracking Rigg

Thread: 4 card cracking Rigg
Post: RE: 4 card cracking Rigg
| (Well, it's not *strictly* a 100% requirement for some attacks - but definitely required for others). You should try to get as close to that as possible, though. |

Thread: 500M hashes
