Subject: RE: Special character (like TAB) in rules
Magnum,
I'm really curious, but where are you encountering non-printable
characters in passwords? Part of the reason I'd like to know is I've been
using tabs as my separators, (due to some of the salts including ':'),
because I'd never thought that people could even use a tab in a password
field. Heck, I actually switch between the username and password fields in a
lot of places by hitting tab since it automatically moves me to the next
field.
Thanks,
Matt Weir

Solar, thanks for your efforts.
Is there a way to specify specific non-printables in rules? Say I want
to prepend a TAB, or match a TAB and replace with a BEL, just as
examples. The documentation does not mention any way to do this. In
external modes, I can use 0x09 of course.
A generic way to specify *any* non-printable, like \x09 or something to
that effect, would be very usable. I thought of placing this
functionality in the preprocessor but keep in mind you may want to use
it in a PP list (like [0-9\x09] for digits + TAB) too. Or even a CR or
LF for that matter. I haven't looked into it yet, any comments off the
top of your head?
Regards
MPI
