Office 2013 Hash only 2000 H/s

[slyexe]

Code:

hashcat -m 9600 -a 3 hash.txt ?a?a?a?a?a?a

?a uses all possible characters and not only letters & numbers. So if you're only wanting both uppercase and lowercase letters & digits you will need to limit your keyspace to only select those options. See the wiki
