A Rule For not more then 2 consecutive number or letter

[philsmd]

I looked in to maskprocessor rule, but i didn't find any.

The answer of atom was for maskprocessor ( https://hashcat.net/wiki/doku.php?id=maskprocessor , http://hashcat.net/tools/maskprocessor/ ), because you mentioned "maskprocessor".

if you look at maskprocessors help display:
mp64.exe --help
...
-q, --seq-max=NUM Maximum number of multiple sequential characters
...

oclHashcat does not directly support this feature, but if you really need it you can pipe the output of maskprocessor into oclHashcat

mp64.exe -q 2 ?a?a?a?a?a?a | oclHashcat64 -m ...
