Character Set question - Technodude_UK - 09-15-2025
Hi. I'm pretty new to Hashcat so apologies if this is a stupid question.
[*]I've got a long, complex password I want to crack but I know it doesn't include all of the characters from the built-in charsets.
[*]For example... I need all of ?l and ?u but only the number 1 and only a % symbol. I've been using ?a but figured I can reduce the combinations needed by a few billion if I can drop unnecessary characters...
[*]
[*]Is there an easy way to create a reduced charset including only those I need please?

[*]
- ?l = abcdefghijklmnopqrstuvwxyz
- ?u = ABCDEFGHIJKLMNOPQRSTUVWXYZ
- ?d = 0123456789
- ?s = «space»!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~

Yes. In the command line,
-1 ?l?u1% ?1?1?1?1?1?1?1?1?1
Or, in the mask file,
?l?u1%,?1?1?1?1?1?1?1?1?1

Awesome. Thank you :-)

Yes — use custom charsets with
-1
..
-4
and masks. Example:
# all lowercase + uppercase + only 1 and %
hashcat -m <type> -a 3 hash.txt -1 ?l?u1% ?1?1?1?1?1?1?1?1
Or split:
# letters + forced 1 or %
hashcat -m <type> -a 3 hash.txt -1 ?l?u -2 1% '?1?1?1?1?1?1?1?2'
?1
,
?2
reference your custom sets. Run multiple masks for different lengths.
