Step 4 took into consideration that some passwords are longer than 14 chars,
and even though LANMAN doesn't support it - we could still use these
characters for part of the analysis. You are correct though, I just chose
to get as much data out of the set as possible. I doubt it affected the
CHR file that much. The amount of passwords generated by step #4
is pretty small in comparison.

Yeah. I think that's what I actually did. But I did step 5 and 6 for the first
time I tested it, to make sure everything was generated correctly.
Better safe than sorry.

Step 3 and 4 will also generate lots of '' strings (blanks). These are
ignored during the CHR generation process so it didn't matter.
But you could easily add a     egrep -v ^$  in there to get rid of them.

The steps mentioned were more of a "rough idea" of how I did it.
Not a copy/paste of the actual command lines.
