BBS E-mail policy Now see if this number is in one of the following ranges:

[1.5 .. 2.5] encrypted text [3 .. 6] regular text [7 .. 8] line noise This is a very simple measure. There are other measures to look for the deviation from an expected distribution, which give much more accurate distinctions. One can very easily separate languages from each other just by looking at such measures. Where does uuencoded [compressed] binary lie? I would suspect it lies right around where encrypted text is. Presumably straight encrypted text is statistically random [7..8], but that when you8 encrypt to just the ascii subset is when you lose the entropy. dean
