Thread: using hashcat to generate file-checksums
Post: RE: using hashcat to generate file-checksums
| File checksumming on gpu would make not much sense because PCIe throughput would be the bottleneck. Besides, GPUs are fast because they have so many cores and can do many computations parallelly. That... |

Thread: using hashcat to generate file-checksums
Post: RE: using hashcat to generate file-checksums
| Sorry, I misread your statement about the bottleneck.
Most checksum functions are not designed to allow parallel processing of a single hashing operation and the sha1/2 familiy is one of that. (due... |

| For slow hashes it does not really matter but for fast hashes piping is slower because everything needs to be transferred from CPU to GPU. |

Thread: Need help with decryption rig
Post: RE: Need help with decryption rig
| You should roughly have ram=vram and go with one cpu core per gpu (this is optional but you don't need to save $100 on the CPU). Some midrange Ryzen would work nicely. |

Thread: Slow Speed With Tesla V100
Post: RE: Slow Speed With Tesla V100
| You can use -w4 for slightly better speed. Other than that, you are comparing a straight wordlist attack with over 3m hashes with a bruteforce on one single hash. Performance will definitely be worse.... |

| I'm not implying anything, it's explained right in that FAQ article. Your mask is too small to be a useful amplifier for a very fast hash type like NTLM. |

Yes, the speed difference is because that's just how hashcat works and for fast hashes there is no good workaround. You may be able to achieve slightly better speed by using a0 with rul... |
