Can't reverse known hash ?

[philsmd]

mask work position-wise, you need to specify the built-in or custom charset (or hardcoded char) for each and every position

so this should work:
cudaHashcat64.exe -a 3 -m 400 hascc.hash hashca?l

and also this:
cudaHashcat64.exe -a 3 -m 400 hascc.hash hash?l?l?l

see also --increment switch.

Please note that the hash file must always be specified before the mask/dictionary/directory/mask file etc

you do not need -1 (or --custom-charset1) since ?l is a built-in charset.
