Generated wordlist size is not right? - strayapanda - 03-26-2017

Hi I would love to crack a password of length 8 with a combination of upper/lower/digit and !@#$%^&*?

I did a rough calculation which should be equal to 71^8 = 6.45753531245761 × 10^14.

But this is what hashcat gave me

The value 39390965405991421 is way more than i expected.
 

Did I do anything wrong?

Is it because I have 61 hashes, thats why it just multiply by 61.

You're right - I'm running it against a single hash, and I get the number you're expecting:

Code:
$ cat myowncharset
!@#$%^&*?

$ ./hashcat -m 5500 -a 3 -1 myowncharset -2 ?1?l?u?d test.hash ?2?2?2?2?2?2?2?2

And you've got it - 645753531245761 x 61 = 39390965405991421, so the number increases as a factor of the number of hashes, because each hash has what is effectively a unique salt.
