Thread: Hashcat running VERY slow
Post: RE: Hashcat running VERY slow
| bcrypt has a cost factor
2 ^ cost factor is determining the iteration count. You can't compare apple to oranges. different cost factors imply different speeds |

Thread: Hashcat running VERY slow
Post: RE: Hashcat running VERY slow
