Need help with building mask

[singhn]

Hi,

I am trying to recover ms access 2010 encrypted database password. I have tried with dictionary but no luck.

I usually keep 8 to 20 char alpha numeric with special char password. Unfortunately, i am not able to recall the password.

I have generated the hash from access database, and I am going to try brute force with min 8 length with increment of 1, however how do i specify the correct mask.

I tried this wiki https://hashcat.net/wiki/doku.php?id=mask_attack

For example, if we use the mask “?l?l?l?l?l?l?l?l” we can only crack a password of the length 8.

but this appears to be only for lowercase

can someone help me with building the mask which can try alpha numeric with special char

Thanks
