My grasp of computing theory isn't terribly strong or theoretical so I hope
others will correct me if anything I say here is inaccurate
I got curious to see if I could find a good basic description of hashing
online so I did a Google search on hash index. I was surprised how many

A hash is a key value pair
i.e. if you want a value for a unique key (in perl anyway) you can do

1 = true,
0 = false
);
If I have a variable that hold an integer such as
$test = 1 I can do the following.
if($status

relates to encryption. What exactly IS a hash index?
Just curious,
