    It is a good starting point, and that's what I thought of as well.
    However, the cutoff here seems to be 8 bytes instead of 7.  I'm still
    looking at it, but the encoding of the second chunk seems dependent on the
    first (e.g. the "321" chunk of "Pa$$word321" is different than that of
    "Password321".
    
    Just my 2 cents.
