Thread: How long to decrypt SHA256
Post: RE: How long to decrypt SHA256
| There's no online calculator that I'm aware of.

Thread: low-end CPU recommendation.
Post: RE: low-end CPU recommendation.
| FWIW, for some attacks I've seen it's good to have one core per GPU. I haven't seen anything that would benefit from multiple cores per GPU. |

Thread: About --keep-guessing

| Almost not at all. I guess it would alter the behavior for any hashes that already keep guessing (is it 7-Zip?) |
