WPA2 hash - limit the amount of capital letters

[gg1103]

Hi Hashcat-users,

I know my wpa2 hash is 10 characters long and consists of numbers, lowercase letters and uppercase letters. But is there easy a way to limit e.g. the numbers so that e.g. maximum can be 5 uppercase letters and 3 numbers.

I have looked at mask attack - but can not figure out if there is a smart solution to limit the combinations in a brute force attack.

I hope you can help and thank you in advance.
I am not the great technician with math skills but have found a lot of help here and on youtube.

Best regards

George
