Thread: Finding all the collisions for a given hash
Post: RE: Finding all the collisions for a given hash
| I don't know of a way to do this with hashcat today.
But the "jumbo" edition of John the Ripper has a "hidden" option (--keep-guessing) that will do this.
For CRC32, the source file has to be asse... |

Thread: Finding all the collisions for a given hash

Thread: Hashcat 1080(s) gpu error
Post: RE: Hashcat 1080(s) gpu error
| Hmm - that seems like enough headroom to me, on each power supply. With ~180W max per 1080 that's only 540W plus 460W for your mainboard, which seems like plenty.
Only other thing I can think of: I... |
