Another question about mask to deal with space

[gale6k]

I'm not sure why you are asking all these mask questions, it is all very well documented on wiki (and/or already asked and answered on forum - use forum search), also see http://hashcat.net/wiki/doku.php?id=mask_attack .

To answer the question, why you want to use hex-charset... hex is just another notation to write out the chars... you don't need it for printable/typeable character (in general)...

The command w/ mask is
-a 3 '?d?d?d?d '

do you see the space at the end? This is very basic cmd/dos/shell standard that you need to quote spaces (and other special characters).

Thank you for your reply.

I tried it, but -a 3 '?d?d?d?d ' do not work.

My total cmd is :
oclHashcat-plus64.exe -a 3 -m 1000 --force -o "ntlm_out.txt" --outfile-format=2 --markov-disable --gpu-temp-disable -i --increment-min=8 --increment-max=8 "ntlm.txt" '?a?a?a?a?a?a 2'

this cmd exit with mask is too small

the password may be start with six ?a and end with space and 2.
