Thread: Help with spaces and rules
Post: RE: Help with spaces and rules
| 'head' just shows the first X lines of output (the default is 10 lines). This is just to make the output shorter, and give a sample from the beginning of the output. |

Post: RE: hashing MS Office 2010 so slow
| Yes, newer Office hashes are pretty slow.
You can add -w 4 and -O; that might help. |

Thread: Bruteforce + Custom characters
Post: RE: Bruteforce + Custom characters
| If the first 8 characters are truly unknown, then the first 8 positions of the mask would be ?a, and the rest would be literal / hard-coded:

Thread: DES ECB error

Thread: Hybrid Attack
Post: RE: Hybrid Attack
| Nevertheless, that's the answer. Because of how hashcat is optimized to run, undersized masks on the left-hand side have more of an impact on speed than undersized masks on the right-hand side. |

Thread: is hashcat still support VCL?
Post: RE: is hashcat still support VCL?
| VCL is no longer supported. Intel GPUs are supported via OpenCL, though there are some known problems with Intel's GPU OpenCL implementation, so YMMV. |
