Do not try to write --keyspace yourself

Keyspace is not the number of words in a wordlist:

Quote:$ wc -l rockyou.txt 
14344391 rockyou.txt
$ ./hashcat --keyspace rockyou.txt 
14344384

So 14344391 != 14344384.

It's also dynamic when it comes to masks:

Quote:$ ./hashcat --keyspace -a 3 ?a
1
$ ./hashcat --keyspace -a 3 ?a?a
95
$ ./hashcat --keyspace -a 3 ?a?a?a
9025
$ ./hashcat --keyspace -a 3 ?a?a?a?a
857375
$ ./hashcat --keyspace -a 3 ?a?a?a?a?a
81450625

So you think you see the logic? Now this:

Quote:$ ./hashcat --keyspace -a 3 ?a?a?a?a?a?a
81450625
$ ./hashcat --keyspace -a 3 ?a?a?a?a?a?a?a
81450625

It's on a limit? No it's not!

Quote:$ ./hashcat --keyspace -a 3 ?a?a?a?a?a?a?a?a
7737809375

And it changes over time:

v3.6.0:

Quote:$ ./hashcat --keyspace rockyou.txt 
14343296

v4.0.x:

Quote:$ ./hashcat --keyspace rockyou.txt 
14344384

So 14343296 != 14344384.

The morale of this: Don't try to emulate how it works, just use --keyspace
