Rules or mask understanding (Specify number of chars/numbers)

[FleetwoodAMAC]

I would do it like so:

Code:

mp64.exe -1 a0 ?1?1?1?1?1?1?1?1 > all_masks.txt
echo "%20%6a" > reject.rule
hashcat-cli64.exe --stdout all_masks.txt -r reject.rule > masks.txt
sed -i 's/a/?l/g;s/0/?d/g' masks.txt

(Using maskprocessor and hashcat-legacy)

Of course, as always, there are multiple ways to do the same thing.

Hi,

I'm having difficulty creating rules for a mixed password. 

I believen it is between 10-12 characters

I know the first letter is Uppercase, and the last is a special character. The rest are upper, lower, numbers and characters.

Is there any way to create rules for something like this?

I'm trying to crack an -m 15700 eth and clearly confused.

Thank you!
