Do not try to write --keyspace yourself

[sjohnny1972]

What is the rationale behind this behavior, just wondering? In the Hashcat help I find: "Show keyspace base:mod values and quit". What is base and mod(ulo)?

When I try with rule expansion the value doesn't increase, I would've guessed otherwise:

Code:

./hashcat64.bin -a 0 -r ../files/best64.rule --keyspace ../files/rockyou.txt
