hashcat mask - phantom001 - 07-19-2020

I am new to hashcat and cant figure out how to make a mask for the following:

min char: 11
max char: 11

on every position the char could be [A-Z] and [0-9].

Maybe some one can show me the way.

first of all it's infeasible to brute-force (and in most cases also mask attack) a hash with a password that is very long and random. It's mathematically imposiible. NOT doable. just do the math (hint: it involves the total cracking speed in H/s and the total keyspace).

to answer your question:
hashcat -m 0 -a 3 --custom-charset2 ?u?d -w 3 -O hash.txt ?2?2?2?2?2?2?2?2?2?2?2

Hint for calculating total keyspace:


Divide this by your actual attack speed in hashes per second. For example, if your speed is 200M H/s, here is how many days it will take to exhaust that mask:
