Are there other ways to test the data?
I've counted the occurances of each byte, they seem to be within a few
hundred
of eachother when I generated a million of them... so it doesn't seem to be
too
biased with any certain characters..
Would generating two huge random documents like this and then xoring them
together
have any value?? If there were two bytes the same at the same position, I
could
count the number of '00000000' bit sets that show up...
something I did find strange, was in a few places, it would have "A%A" or
"7?7" ... I think that might be a bit of a problem.. (although "[A]"
probably
isn't)...
