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: DES ECB error

| But why does the cracking approach sometimes find one first, and sometimes find the other one first? I would expect the attack to be deterministic and reproducible. |
