Post: RE: Do not try to write --keyspace yourself

Thread: How do I speed up my laptop

Thread: Bruteforce + rules
Post: RE: Bruteforce + rules
| To fully take advantage of GPU for a fast hash like MD5, you have to have more than a few rules.
You might try emulating a hybrid attack with generated rules.
