Subject: RE: Wordlist Mangling Rule

Thanks Solar Designer,

The rule was more designed around the assumption that most residential AP's
protected with WPA etc
Probably have a 8 character or shorter word, possibly beginning with a
capital, and if not 8 digits then made
To come to 8 by adding the appropriate number of digits, probably 123 etc.

Do that make a rule any simpler to generate?

I find the above a bit inconsistent, but here you are:

-\r[c:c] <B >7 \p[clu]
-\r[c:c] <8 >6 \p[clu] $[0-9]
-\r[c:c] <7 >5 \p[clu] Az"[0-9][0-9]"
-\r[c:c] <6 >4 \p[clu] Az"[0-9][0-9][0-9]"
-\r[c:c] <5 >3 \p[clu] Az"[0-9][0-9][0-9][0-9]"

This includes some extra complexity to deal with case-insensitive hashes
optimally.  If you don't need that, or if you're using an older version of
JtR that does not understand the '\r' flag, you can simplify to:

<B >7 [clu]
<8 >6 [clu] $[0-9]
<7 >5 [clu] Az"[0-9][0-9]"
<6 >4 [clu] Az"[0-9][0-9][0-9]"
<5 >3 [clu] Az"[0-9][0-9][0-9][0-9]"

There's no performance difference between these two with case-sensitive
hashes, but the first one is up to 3x faster for case-insensitive.
