Alphanumeric password + signs

[HostileBlue2020]

Hello. I'm trying to learn, but I can't get a mask that gets a wifi password of a size of between 6 and 12 characters, which can be uppercase and lowercase letters, numbers and signs.

Hey

The mask you want to use is "?a"

So for 6 it would be "?a?a?a?a?a?a"

Just be aware, even if you have a great machine that around 8 characters this will take years to finish
